-This chapter describes how to use the GNU History Library interactively,
-from a user's standpoint.  It should be considered a user's guide.  For
-information on using the GNU History Library in your own programs,
-see section <A HREF="history.html#SEC6">Programming with GNU History</A>.

-The History library provides a history expansion feature that is similar
-to the history expansion provided by <CODE>csh</CODE>.  This section
-describes the syntax used to manipulate the history information.
-
-</P>
-<P>
-History expansions introduce words from the history list into
-the input stream, making it easy to repeat commands, insert the
-arguments to a previous command into the current input line, or
-fix errors in previous commands quickly.
-
-</P>
-<P>
-History expansion takes place in two parts.  The first is to determine
-which line from the history list should be used during substitution.
-The second is to select portions of that line for inclusion into the
-current one.  The line selected from the history is called the
-<EM>event</EM>, and the portions of that line that are acted upon are
-called <EM>words</EM>.  Various <EM>modifiers</EM> are available to manipulate
-the selected words.  The line is broken into words in the same fashion
-that Bash does, so that several words
-surrounded by quotes are considered one word.
-History expansions are introduced by the appearance of the
-history expansion character, which is <SAMP>`!'</SAMP> by default.

-
-<P>
-Many programs read input from the user a line at a time.  The GNU History
-library is able to keep track of those lines, associate arbitrary data with
-each line, and utilize information from previous lines in composing new
-ones.
-
-</P>
-<P>
-The programmer using the History library has available functions
-for remembering lines on a history list, associating arbitrary data
-with a line, removing lines from the list, searching through the list
-for a line containing an arbitrary text string, and referencing any line
-in the list directly.  In addition, a history <EM>expansion</EM> function
-is available which provides for a consistent user interface across
-different programs.
-
-</P>
-<P>
-The user using programs written with the History library has the
-benefit of a consistent user interface with a set of well-known
-commands for manipulating the text of previous lines and using that text
-in new commands.  The basic history manipulation commands are similar to
-the history substitution provided by <CODE>csh</CODE>.
-
-</P>
-<P>
-If the programmer desires, he can use the Readline library, which
-includes some history manipulation by default, and has the added
-advantage of command line editing.
-
-</P>
-<P>
-Before declaring any functions using any functionality the History
-library provides in other code, an application writer should include
-the file <CODE>&#60;readline/history.h&#62;</CODE> in any file that uses the
-History library's features.  It supplies extern declarations for all
-of the library's public functions and variables, and declares all of
-the public data structures.

-<H2><A NAME="SEC8" HREF="history.html#TOC8">History Storage</A></H2>

-The history list is an array of history entries.  A history entry is

-} HIST_ENTRY;
-</PRE>
-
-<P>

-History Expansion
-=================
-
-   The History library provides a history expansion feature that is
-similar to the history expansion provided by `csh'.  This section
-describes the syntax used to manipulate the history information.
-
-   History expansions introduce words from the history list into the
-input stream, making it easy to repeat commands, insert the arguments
-to a previous command into the current input line, or fix errors in
-previous commands quickly.
-
-   History expansion takes place in two parts.  The first is to
-determine which line from the history list should be used during
-substitution.  The second is to select portions of that line for
-inclusion into the current one.  The line selected from the history is
-called the "event", and the portions of that line that are acted upon
-are called "words".  Various "modifiers" are available to manipulate
-the selected words.  The line is broken into words in the same fashion
-that Bash does, so that several words surrounded by quotes are
-considered one word.  History expansions are introduced by the
-appearance of the history expansion character, which is `!' by default.

-

-
-Event Designators
------------------
-
-   An event designator is a reference to a command line entry in the
-history list.
-
-`!'
-     Start a history substitution, except when followed by a space, tab,
-     the end of the line, `=' or `('.
-
-`!N'
-     Refer to command line N.
-
-`!-N'
-     Refer to the command N lines back.
-
-`!!'
-     Refer to the previous command.  This is a synonym for `!-1'.
-
-`!STRING'
-     Refer to the most recent command starting with STRING.
-
-`!?STRING[?]'
-     Refer to the most recent command containing STRING.  The trailing
-     `?' may be omitted if the STRING is followed immediately by a
-     newline.
-
-`^STRING1^STRING2^'
-     Quick Substitution.  Repeat the last command, replacing STRING1
-     with STRING2.  Equivalent to `!!:s/STRING1/STRING2/'.
-
-`!#'
-     The entire command line typed so far.
-
-
-File: history.info,  Node: Word Designators,  Next: Modifiers,  Prev: Event Designators,  Up: History Interaction
-
-Word Designators
-----------------
-
-   Word designators are used to select desired words from the event.  A
-`:' separates the event specification from the word designator.  It may
-be omitted if the word designator begins with a `^', `$', `*', `-', or
-`%'.  Words are numbered from the beginning of the line, with the first
-word being denoted by 0 (zero).  Words are inserted into the current
-line separated by single spaces.
-
-   For example,
-
-`!!'
-     designates the preceding command.  When you type this, the
-     preceding command is repeated in toto.
-
-`!!:$'
-     designates the last argument of the preceding command.  This may be
-     shortened to `!$'.
-
-`!fi:2'
-     designates the second argument of the most recent command starting
-     with the letters `fi'.
-
-   Here are the word designators:
-
-`0 (zero)'
-     The `0'th word.  For many applications, this is the command word.
-
-`N'
-     The Nth word.
-
-`^'
-     The first argument; that is, word 1.
-
-`$'
-     The last argument.
-
-`%'
-     The word matched by the most recent `?STRING?' search.
-
-`X-Y'
-     A range of words; `-Y' abbreviates `0-Y'.
-
-`*'
-     All of the words, except the `0'th.  This is a synonym for `1-$'.
-     It is not an error to use `*' if there is just one word in the
-     event; the empty string is returned in that case.
-
-`X*'
-     Abbreviates `X-$'
-
-`X-'
-     Abbreviates `X-$' like `X*', but omits the last word.
-
-   If a word designator is supplied without an event specification, the
-previous command is used as the event.
-
-
-File: history.info,  Node: Modifiers,  Prev: Word Designators,  Up: History Interaction
-
-Modifiers
----------
-
-   After the optional word designator, you can add a sequence of one or
-more of the following modifiers, each preceded by a `:'.
-
-`h'
-     Remove a trailing pathname component, leaving only the head.
-
-`t'
-     Remove all leading  pathname  components, leaving the tail.
-
-`r'
-     Remove a trailing suffix of the form `.SUFFIX', leaving the
-     basename.
-
-`e'
-     Remove all but the trailing suffix.
-
-`p'
-     Print the new command but do not execute it.
-
-`s/OLD/NEW/'
-     Substitute NEW for the first occurrence of OLD in the event line.
-     Any delimiter may be used in place of `/'.  The delimiter may be
-     quoted in OLD and NEW with a single backslash.  If `&' appears in
-     NEW, it is replaced by OLD.  A single backslash will quote the
-     `&'.  The final delimiter is optional if it is the last character
-     on the input line.
-
-`&'
-     Repeat the previous substitution.
-
-`g'
-     Cause changes to be applied over the entire event line.  Used in
-     conjunction with `s', as in `gs/OLD/NEW/', or with `&'.

-Introduction to History
-=======================
-
-   Many programs read input from the user a line at a time.  The GNU
-History library is able to keep track of those lines, associate
-arbitrary data with each line, and utilize information from previous
-lines in composing new ones.
-
-   The programmer using the History library has available functions for
-remembering lines on a history list, associating arbitrary data with a
-line, removing lines from the list, searching through the list for a
-line containing an arbitrary text string, and referencing any line in
-the list directly.  In addition, a history "expansion" function is
-available which provides for a consistent user interface across
-different programs.
-
-   The user using programs written with the History library has the
-benefit of a consistent user interface with a set of well-known
-commands for manipulating the text of previous lines and using that text
-in new commands.  The basic history manipulation commands are similar to
-the history substitution provided by `csh'.
-
-   If the programmer desires, he can use the Readline library, which
-includes some history manipulation by default, and has the added
-advantage of command line editing.
-
-   Before declaring any functions using any functionality the History
-library provides in other code, an application writer should include
-the file `<readline/history.h>' in any file that uses the History
-library's features.  It supplies extern declarations for all of the
-library's public functions and variables, and declares all of the
-public data structures.
-
-
-File: history.info,  Node: History Storage,  Next: History Functions,  Prev: Introduction to History,  Up: Programming with GNU History
-
-History Storage
-===============
-
-   The history list is an array of history entries.  A history entry is
-declared as follows:
-
-     typedef struct _hist_entry {
-       char *line;
-       char *data;
-     } HIST_ENTRY;
-
-   The history list itself might therefore be declared as
-
-     HIST_ENTRY **the_history_list;
-
-   The state of the History library is encapsulated into a single
-structure:
-
-     /* A structure used to pass the current state of the history stuff around. */
-     typedef struct _hist_state {
-       HIST_ENTRY **entries;         /* Pointer to the entries themselves. */
-       int offset;                   /* The location pointer within this array. */
-       int length;                   /* Number of elements within this array. */
-       int size;                     /* Number of slots allocated to this array. */
-       int flags;
-     } HISTORY_STATE;
-
-   If the flags member includes `HS_STIFLED', the history has been
-stifled.

-     removed element is returned so you can free the line, data, and
-     containing structure.
-
- - Function: HIST_ENTRY * replace_history_entry (int which, char *line,
-          char *data)
-     Make the history entry at offset WHICH have LINE and DATA.  This
-     returns the old entry so you can dispose of the data.  In the case
-     of an invalid WHICH, a `NULL' pointer is returned.
-
- - Function: void clear_history ()
-     Clear the history list by deleting all the entries.
-
- - Function: void stifle_history (int max)
-     Stifle the history list, remembering only the last MAX entries.
-
- - Function: int unstifle_history ()
-     Stop stifling the history.  This returns the previous amount the
-     history was stifled.  The value is positive if the history was
-     stifled, negative if it wasn't.
-
- - Function: int history_is_stifled ()
-     Returns non-zero if the history is stifled, zero if it is not.
-

-
-Information About the History List
-----------------------------------
-
-   These functions return information about the entire history list or
-individual list entries.
-
- - Function: HIST_ENTRY ** history_list ()
-     Return a `NULL' terminated array of `HIST_ENTRY' which is the
-     current input history.  Element 0 of this list is the beginning of
-     time.  If there is no history, return `NULL'.
-
- - Function: int where_history ()
-     Returns the offset of the current history element.
-
- - Function: HIST_ENTRY * current_history ()
-     Return the history entry at the current position, as determined by

-     pointer.
-
- - Function: HIST_ENTRY * history_get (int offset)
-     Return the history entry at position OFFSET, starting from
-     `history_base'.  If there is no entry there, or if OFFSET is
-     greater than the history length, return a `NULL' pointer.
-
- - Function: int history_total_bytes ()
-     Return the number of bytes that the primary history entries are
-     using.  This function returns the sum of the lengths of all the
-     lines in the history.

-
-Moving Around the History List
-------------------------------
-
-   These functions allow the current index into the history list to be
-set or changed.
-
- - Function: int history_set_pos (int pos)
-     Set the position in the history list to POS, an absolute index
-     into the list.
-
- - Function: HIST_ENTRY * previous_history ()
-     Back up the current history offset to the previous history entry,
-     and return a pointer to that entry.  If there is no previous
-     entry, return a `NULL' pointer.
-
- - Function: HIST_ENTRY * next_history ()
-     Move the current history offset forward to the next history entry,
-     and return the a pointer to that entry.  If there is no next
-     entry, return a `NULL' pointer.
-
-
-File: history.info,  Node: Searching the History List,  Next: Managing the History File,  Prev: Moving Around the History List,  Up: History Functions
-
-Searching the History List
---------------------------
-
-   These functions allow searching of the history list for entries
-containing a specific string.  Searching may be performed both forward
-and backward from the current history position.  The search may be
-"anchored", meaning that the string must match at the beginning of the
-history entry.
-
- - Function: int history_search (char *string, int direction)
-     Search the history for STRING, starting at the current history
-     offset.  If DIRECTION < 0, then the search is through previous
-     entries, else through subsequent.  If STRING is found, then the
-     current history index is set to that history entry, and the value
-     returned is the offset in the line of the entry where STRING was
-     found.  Otherwise, nothing is changed, and a -1 is returned.
-
- - Function: int history_search_prefix (char *string, int direction)
-     Search the history for STRING, starting at the current history
-     offset.  The search is anchored: matching lines must begin with
-     STRING.  If DIRECTION < 0, then the search is through previous
-     entries, else through subsequent.  If STRING is found, then the
-     current history index is set to that entry, and the return value
-     is 0.  Otherwise, nothing is changed, and a -1 is returned.
-
- - Function: int history_search_pos (char *string, int direction, int
-          pos)
-     Search for STRING in the history list, starting at POS, an
-     absolute index into the list.  If DIRECTION is negative, the search
-     proceeds backward from POS, otherwise forward.  Returns the
-     absolute index of the history element where STRING was found, or
-     -1 otherwise.

-
-Managing the History File
--------------------------
-
-   The History library can read the history from and write it to a file.
-This section documents the functions for managing a history file.
-
- - Function: int read_history (char *filename)
-     Add the contents of FILENAME to the history list, a line at a
-     time.  If FILENAME is `NULL', then read from `~/.history'.
-     Returns 0 if successful, or errno if not.
-
- - Function: int read_history_range (char *filename, int from, int to)
-     Read a range of lines from FILENAME, adding them to the history
-     list.  Start reading at line FROM and end at TO.  If FROM is zero,
-     start at the beginning.  If TO is less than FROM, then read until
-     the end of the file.  If FILENAME is `NULL', then read from
-     `~/.history'.  Returns 0 if successful, or `errno' if not.
-
- - Function: int write_history (char *filename)
-     Write the current history to FILENAME, overwriting FILENAME if
-     necessary.  If FILENAME is `NULL', then write the history list to
-     `~/.history'.  Values returned are as in `read_history ()'.
-
- - Function: int append_history (int nelements, char *filename)
-     Append the last NELEMENTS of the history list to FILENAME.
-
- - Function: int history_truncate_file (char *filename, int nlines)
-     Truncate the history file FILENAME, leaving only the last NLINES
-     lines.

-History Expansion
------------------
-
-   These functions implement `csh'-like history expansion.
-
- - Function: int history_expand (char *string, char **output)
-     Expand STRING, placing the result into OUTPUT, a pointer to a
-     string (*note History Interaction::.).  Returns:
-    `0'
-          If no expansions took place (or, if the only change in the
-          text was the de-slashifying of the history expansion
-          character);
-
-    `1'
-          if expansions did take place;
-
-    `-1'
-          if there was an error in expansion;
-
-    `2'
-          if the returned line should be displayed, but not executed,
-          as with the `:p' modifier (*note Modifiers::.).
-
-     If an error ocurred in expansion, then OUTPUT contains a
-     descriptive error message.
-
- - Function: char * history_arg_extract (int first, int last, char
-          *string)
-     Extract a string segment consisting of the FIRST through LAST
-     arguments present in STRING.  Arguments are broken up as in Bash.
-
- - Function: char * get_history_event (char *string, int *cindex, int
-          qchar)
-     Returns the text of the history event beginning at STRING +
-     *CINDEX.  *CINDEX is modified to point to after the event
-     specifier.  At function entry, CINDEX points to the index into
-     STRING where the history event specification begins.  QCHAR is a
-     character that is allowed to end the event specification in
-     addition to the "normal" terminating characters.
-
- - Function: char ** history_tokenize (char *string)
-     Return an array of tokens parsed out of STRING, much as the shell
-     might.  The tokens are split on white space and on the characters
-     `()<>;&|$', and shell quoting conventions are obeyed.

-History Variables
-=================
-
-   This section describes the externally visible variables exported by
-the GNU History Library.
-
- - Variable: int history_base
-     The logical offset of the first entry in the history list.
-
- - Variable: int history_length
-     The number of entries currently stored in the history list.
-
- - Variable: int max_input_history
-     The maximum number of history entries.  This must be changed using
-     `stifle_history ()'.
-
- - Variable: char history_expansion_char
-     The character that starts a history event.  The default is `!'.
-
- - Variable: char history_subst_char
-     The character that invokes word substitution if found at the start
-     of a line.  The default is `^'.
-
- - Variable: char history_comment_char
-     During tokenization, if this character is seen as the first
-     character of a word, then it and all subsequent characters up to a
-     newline are ignored, suppressing history expansion for the
-     remainder of the line.  This is disabled by default.
-
- - Variable: char * history_no_expand_chars
-     The list of characters which inhibit history expansion if found
-     immediately following HISTORY_EXPANSION_CHAR.  The default is
-     whitespace and `='.
-
- - Variable: char * history_search_delimiter_chars
-     The list of additional characters which can delimit a history
-     search string, in addition to whitespace, `:' and `?' in the case
-     of a substring search.  The default is empty.
-
- - Variable: int history_quotes_inhibit_expansion
-     If non-zero, single-quoted words are not scanned for the history
-     expansion character.  The default value is 0.
-
- - Variable: Function * history_inhibit_expansion_function
-     This should be set to the address of a function that takes two
-     arguments: a `char *' (STRING) and an integer index into that
-     string (I).  It should return a non-zero value if the history
-     expansion starting at STRING[I] should not be performed; zero if
-     the expansion should be done.  It is intended for use by
-     applications like Bash that use the history expansion character
-     for additional purposes.  By default, this variable is set to NULL.

-       rreeaaddlliinnee will read a line from the terminal and return it,
-       using pprroommpptt as a prompt.  If pprroommpptt is null, no prompt is
-       issued.  The line returned is allocated with _m_a_l_l_o_c(3), so
-       the  caller must free it when finished.  The line returned
-       has the final newline removed, so only  the  text  of  the
-       line remains.
-
-       rreeaaddlliinnee  offers  editing  capabilities  while the user is
-       entering the line.  By default, the line editing  commands
-       are  similar  to  those of emacs.  A vi-style line editing
-       interface is also available.
-
-RREETTUURRNN VVAALLUUEE
-       rreeaaddlliinnee returns the text of the line read.  A blank  line
-       returns  the  empty  string.   If EEOOFF is encountered while
-       reading a line, and the line is empty, NNUULLLL  is  returned.
-       If  an EEOOFF is read with a non-empty line, it is treated as
-       a newline.
-
-NNOOTTAATTIIOONN
-       An emacs-style notation  is  used  to  denote  keystrokes.
-       Control  keys  are  denoted by C-_k_e_y, e.g., C-n means Con-
-       trol-N.  Similarly, _m_e_t_a keys are denoted by M-_k_e_y, so M-x
-       means Meta-X.  (On keyboards without a _m_e_t_a key, M-_x means
-       ESC _x, i.e., press the Escape key then the  _x  key.   This
-       makes  ESC  the  _m_e_t_a _p_r_e_f_i_x.  The combination M-C-_x means
-       ESC-Control-_x, or press the Escape key then hold the  Con-
-       trol key while pressing the _x key.)
-
-       Readline  commands  may  be given numeric _a_r_g_u_m_e_n_t_s, which
-       normally act as a repeat count.  Sometimes, however, it is
-       the  sign  of the argument that is significant.  Passing a
-       negative argument to a command that acts  in  the  forward
-       direction  (e.g., kkiillll--lliinnee) causes that command to act in
-       a backward direction.  Commands whose behavior with  argu-
-       ments deviates from this are noted.
-
-       When  a  command  is  described  as _k_i_l_l_i_n_g text, the text

-       deleted is saved for possible future retrieval  (_y_a_n_k_i_n_g).
-       The  killed  text  is  saved  in a _k_i_l_l _r_i_n_g.  Consecutive
-       kills cause the text to  be  accumulated  into  one  unit,
-       which  can  be  yanked all at once.  Commands which do not
-       kill text separate the chunks of text on the kill ring.
-
-IINNIITTIIAALLIIZZAATTIIOONN FFIILLEE
-       Readline is customized by putting commands in an  initial-
-       ization file (the _i_n_p_u_t_r_c file).  The name of this file is
-       taken from the value of the IINNPPUUTTRRCC environment  variable.
-       If  that  variable  is  unset,  the default is _~_/_._i_n_p_u_t_r_c.
-       When a program which uses the readline library starts  up,
-       the  init file is read, and the key bindings and variables
-       are set.  There are only a few basic constructs allowed in
-       the  readline  init file.  Blank lines are ignored.  Lines
-       beginning with a ## are comments.  Lines beginning with a $$
-       indicate  conditional  constructs.  Other lines denote key
-       bindings and variable settings.  Each program  using  this
-       library may add its own commands and bindings.
-
-       For example, placing
-
-              M-Control-u: universal-argument
-       or
-              C-Meta-u: universal-argument
-       into  the  _i_n_p_u_t_r_c  would  make M-C-u execute the readline
-       command _u_n_i_v_e_r_s_a_l_-_a_r_g_u_m_e_n_t.
-
-       The following  symbolic  character  names  are  recognized
-       while processing key bindings: _R_U_B_O_U_T, _D_E_L, _E_S_C, _L_F_D, _N_E_W_-
-       _L_I_N_E, _R_E_T, _R_E_T_U_R_N, _S_P_C, _S_P_A_C_E, and _T_A_B.
-
-       In addition to command names, readline allows keys  to  be
-       bound to a string that is inserted when the key is pressed
-       (a _m_a_c_r_o).
-
-
-   KKeeyy BBiinnddiinnggss
-       The syntax for controlling key  bindings  in  the  _i_n_p_u_t_r_c
-       file  is  simple.  All that is required is the name of the
-       command or the text of a macro and a key sequence to which
-       it  should  be  bound. The name may be specified in one of
-       two ways: as a symbolic key name, possibly with  _M_e_t_a_-  or
-       _C_o_n_t_r_o_l_-  prefixes,  or as a key sequence.  When using the
-       form kkeeyynnaammee:_f_u_n_c_t_i_o_n_-_n_a_m_e or _m_a_c_r_o, _k_e_y_n_a_m_e is  the  name
-       of a key spelled out in English.  For example:
-
-              Control-u: universal-argument
-              Meta-Rubout: backward-kill-word
-              Control-o: ">&output"
-
-       In the above example, _C_-_u is bound to the function uunniivveerr--
-       ssaall--aarrgguummeenntt,  _M_-_D_E_L  is  bound  to  the  function   bbaacckk--
-       wwaarrdd--kkiillll--wwoorrdd,   and  _C_-_o  is  bound  to  run  the  macro

-       sseeqq differs from kkeeyynnaammee above in that strings denoting an
-       entire  key  sequence  may  be  specified  by  placing the
-       sequence within double quotes.  Some GNU Emacs  style  key
-       escapes can be used, as in the following example.
-
-              "\C-u": universal-argument
-              "\C-x\C-r": re-read-init-file
-              "\e[11~": "Function Key 1"
-
-       In  this  example, _C_-_u is again bound to the function uunnii--
-       vveerrssaall--aarrgguummeenntt.   _C_-_x  _C_-_r  is  bound  to  the   function
-       rree--rreeaadd--iinniitt--ffiillee,  and _E_S_C _[ _1 _1 _~ is bound to insert the
-       text FFuunnccttiioonn KKeeyy 11.  The full  set  of  GNU  Emacs  style
-       escape sequences is
-              \\CC--    control prefix
-              \\MM--    meta prefix
-              \\ee     an escape character
-              \\\\     backslash
-              \\""     literal "
-              \\''     literal '
-
-       In  addition  to  the  GNU Emacs style escape sequences, a
-       second set of backslash escapes is available:
-              \\aa     alert (bell)
-              \\bb     backspace
-              \\dd     delete
-              \\ff     form feed
-              \\nn     newline
-              \\rr     carriage return
-              \\tt     horizontal tab
-              \\vv     vertical tab
-              \\_n_n_n   the character whose ASCII code is the  octal
-                     value _n_n_n (one to three digits)
-              \\xx_n_n_n  the  character  whose ASCII code is the hex-
-                     adecimal value _n_n_n (one to three digits)
-
-       When entering the text of a macro, single or double quotes
-       should  be  used to indicate a macro definition.  Unquoted
-       text is assumed to be a function name.  In the macro body,
-       the backslash escapes described above are expanded.  Back-
-       slash will quote any other character in  the  macro  text,
-       including " and '.
-
-       BBaasshh  allows  the current readline key bindings to be dis-

-       using the --oo option to the  sseett  builtin  command.   Other
-       programs  using  this  library provide similar mechanisms.

-   VVaarriiaabblleess
-       Readline has variables that can be used  to  further  cus-
-       tomize its behavior.  A variable may be set in the _i_n_p_u_t_r_c
-       file with a statement of the form
-
-              sseett _v_a_r_i_a_b_l_e_-_n_a_m_e _v_a_l_u_e
-
-       Except where noted, readline variables can take the values
-       OOnn or OOffff.  The variables and their default values are:
-
-       bbeellll--ssttyyllee ((aauuddiibbllee))
-              Controls  what  happens when readline wants to ring
-              the terminal bell.  If set to nnoonnee, readline  never
-              rings the bell.  If set to vviissiibbllee, readline uses a
-              visible bell if one is available.  If set to  aauuddii--
-              bbllee, readline attempts to ring the terminal's bell.
-       ccoommmmeenntt--bbeeggiinn ((````##''''))
-              The string that is inserted in  vvii  mode  when  the
-              iinnsseerrtt--ccoommmmeenntt  command  is executed.  This command
-              is bound to MM--## in emacs mode and to ## in  vi  com-
-              mand mode.
-       ccoommpplleettiioonn--iiggnnoorree--ccaassee ((OOffff))
-              If  set  to OOnn, readline performs filename matching
-              and completion in a case-insensitive fashion.
-       ccoommpplleettiioonn--qquueerryy--iitteemmss ((110000))
-              This determines when  the  user  is  queried  about
-              viewing  the  number of possible completions gener-
-              ated by the ppoossssiibbllee--ccoommpplleettiioonnss command.   It  may
-              be  set  to any integer value greater than or equal
-              to zero.  If the number of possible completions  is
-              greater  than  or  equal to the value of this vari-
-              able, the user is asked whether or not he wishes to
-              view  them; otherwise they are simply listed on the
-              terminal.
-       ccoonnvveerrtt--mmeettaa ((OOnn))
-              If set to OOnn, readline will convert characters with
-              the  eighth  bit  set  to  an ASCII key sequence by
-              stripping the eighth bit and prepending  an  escape
-              character (in effect, using escape as the _m_e_t_a _p_r_e_-
-              _f_i_x).
-       ddiissaabbllee--ccoommpplleettiioonn ((OOffff))
-              If set to OOnn, readline will  inhibit  word  comple-
-              tion.   Completion characters will be inserted into
-              the line as if they had been mapped to sseellff--iinnsseerrtt.
-       eeddiittiinngg--mmooddee ((eemmaaccss))
-              Controls  whether readline begins with a set of key
-              bindings similar to _e_m_a_c_s or _v_i.  eeddiittiinngg--mmooddee  can
-              be set to either eemmaaccss or vvii.
-       eennaabbllee--kkeeyyppaadd ((OOffff))
-              When  set  to  OOnn,  readline will try to enable the
-              application keypad when it is called.  Some systems
-              need this to enable the arrow keys.

-       hhoorriizzoonnttaall--ssccrroollll--mmooddee ((OOffff))
-              When set to OOnn, makes readline use  a  single  line

-              single screen line when it becomes longer than  the
-              screen width rather than wrapping to a new line.
-       iinnppuutt--mmeettaa ((OOffff))
-              If  set to OOnn, readline will enable eight-bit input
-              (that is, it will not strip the high bit  from  the
-              characters it reads), regardless of what the termi-
-              nal claims it can support.  The name mmeettaa--ffllaagg is a
-              synonym for this variable.
-       iisseeaarrcchh--tteerrmmiinnaattoorrss ((````CC--[[CC--JJ''''))
-              The  string  of characters that should terminate an
-              incremental search without  subsequently  executing
-              the  character  as a command.  If this variable has
-              not been given a value, the characters _E_S_C and  _C_-_J
-              will terminate an incremental search.
-       kkeeyymmaapp ((eemmaaccss))
-              Set  the current readline keymap.  The set of legal
-              keymap names is _e_m_a_c_s_, _e_m_a_c_s_-_s_t_a_n_d_a_r_d_,  _e_m_a_c_s_-_m_e_t_a_,
-              _e_m_a_c_s_-_c_t_l_x_, _v_i_, _v_i_-_m_o_v_e_, _v_i_-_c_o_m_m_a_n_d, and _v_i_-_i_n_s_e_r_t.
-              _v_i is equivalent to _v_i_-_c_o_m_m_a_n_d; _e_m_a_c_s is equivalent
-              to _e_m_a_c_s_-_s_t_a_n_d_a_r_d.  The default value is _e_m_a_c_s; the
-              value of  eeddiittiinngg--mmooddee  also  affects  the  default
-              keymap.

-       oouuttppuutt--mmeettaa ((OOffff))
-              If set to OOnn, readline will display characters with

-              prefixed escape sequence.
-       pprriinntt--ccoommpplleettiioonnss--hhoorriizzoonnttaallllyy ((OOffff))
-              If  set  to  OOnn,  readline will display completions

-              order, rather than down the screen.
-       sshhooww--aallll--iiff--aammbbiigguuoouuss ((OOffff))
-              This  alters the default behavior of the completion
-              functions.  If set to oonn,  words  which  have  more
-              than  one  possible completion cause the matches to
-              be listed immediately instead of ringing the  bell.
-       vviissiibbllee--ssttaattss ((OOffff))
-              If set to OOnn, a character denoting a file's type as

-       conditional compilation features  of  the  C  preprocessor
-       which allows key bindings and variable settings to be per-
-       formed as the result of  tests.   There  are  four  parser
-       directives used.
-
-       $$iiff    The  $$iiff construct allows bindings to be made based
-              on the editing mode, the terminal  being  used,  or
-              the  application  using  readline.  The text of the
-              test extends to the end of the line; no  characters
-              are required to isolate it.
-
-              mmooddee   The  mmooddee== form of the $$iiff directive is used
-                     to test whether readline is in emacs  or  vi
-                     mode.   This may be used in conjunction with
-                     the sseett kkeeyymmaapp command, for instance, to set
-                     bindings  in  the  _e_m_a_c_s_-_s_t_a_n_d_a_r_d and _e_m_a_c_s_-
-                     _c_t_l_x keymaps only if  readline  is  starting
-                     out in emacs mode.
-
-              tteerrmm   The tteerrmm== form may be used to include termi-
-                     nal-specific key bindings, perhaps  to  bind
-                     the  key  sequences output by the terminal's
-                     function keys.  The word on the  right  side
-                     of  the == is tested against the full name of
-                     the terminal and the portion of the terminal
-                     name before the first --.  This allows _s_u_n to
-                     match both _s_u_n and _s_u_n_-_c_m_d, for instance.
-
-              aapppplliiccaattiioonn
-                     The aapppplliiccaattiioonn construct is used to include
-                     application-specific settings.  Each program
-                     using the readline library sets the _a_p_p_l_i_c_a_-
-                     _t_i_o_n  _n_a_m_e,  and  an initialization file can
-                     test for a particular value.  This could  be
-                     used to bind key sequences to functions use-
-                     ful for a specific program.   For  instance,
-                     the  following  command  adds a key sequence
-                     that quotes the current or previous word  in
-                     Bash:
-
-                     $$iiff bash
-                     # Quote the current or previous word
-                     "\C-xq": "\eb\"\ef\""
-                     $$eennddiiff
-
-       $$eennddiiff This command, as seen in the previous example, ter-
-              minates an $$iiff command.
-
-       $$eellssee  Commands in this branch of the  $$iiff  directive  are
-              executed if the test fails.
-
-       $$iinncclluuddee
-              This  directive takes a single filename as an argu-
-              ment and reads  commands  and  bindings  from  that

-SSEEAARRCCHHIINNGG
-       Readline provides commands for searching through the  com-
-       mand  history  for  lines  containing  a specified string.
-       There are two search modes: _i_n_c_r_e_m_e_n_t_a_l and  _n_o_n_-_i_n_c_r_e_m_e_n_-
-       _t_a_l.
-
-       Incremental  searches  begin  before the user has finished
-       typing the search string.  As each character of the search
-       string is typed, readline displays the next entry from the
-       history matching the string typed so far.  An  incremental
-       search  requires only as many characters as needed to find
-       the desired history entry.  The characters present in  the
-       value of the _i_s_e_a_r_c_h_-_t_e_r_m_i_n_a_t_o_r_s variable are used to ter-
-       minate an incremental search.  If that  variable  has  not
-       been  assigned a value the Escape and Control-J characters
-       will terminate  an  incremental  search.   Control-G  will
-       abort an incremental search and restore the original line.
-       When the search is terminated, the history entry  contain-
-       ing  the  search string becomes the current line.  To find
-       other matching entries in the history list, type Control-S
-       or Control-R as appropriate.  This will search backward or
-       forward in the history for  the  next  line  matching  the
-       search  string typed so far.  Any other key sequence bound
-       to a readline command will terminate the search  and  exe-
-       cute that command.  For instance, a _n_e_w_l_i_n_e will terminate
-       the search and accept the line, thereby executing the com-
-       mand from the history list.
-
-       Non-incremental  searches  read  the  entire search string
-       before starting to search for matching history lines.  The
-       search  string  may be typed by the user or be part of the
-       contents of the current line.

-       uunniivveerrssaall--aarrgguummeenntt
-              This is another way to  specify  an  argument.   If

-              optionally with a leading minus sign, those  digits
-              define the argument.  If the command is followed by
-              digits, executing uunniivveerrssaall--aarrgguummeenntt again ends the
-              numeric  argument,  but is otherwise ignored.  As a
-              special case, if this command is  immediately  fol-
-              lowed  by  a  character  that is neither a digit or
-              minus sign, the argument count for the next command
-              is  multiplied by four.  The argument count is ini-
-              tially one, so executing this  function  the  first
-              time  makes  the argument count four, a second time

-       The  following is a list of the default emacs and vi bind-
-       ings.  Characters with the 8th  bit  set  are  written  as
-       M-<character>, and are referred to as _m_e_t_a_f_i_e_d characters.
-       The printable ASCII characters not mentioned in  the  list
-       of  emacs  standard  bindings are bound to the _s_e_l_f_-_i_n_s_e_r_t
-       function, which just inserts the given character into  the
-       input  line.   In  vi  insertion  mode, all characters not
-       specifically mentioned are bound to _s_e_l_f_-_i_n_s_e_r_t.   Charac-
-       ters  assigned to signal generation by _s_t_t_y(1) or the ter-
-       minal driver, such as C-Z or C-C,  retain  that  function.
-       Upper  and lower case _m_e_t_a_f_i_e_d characters are bound to the
-       same function in the emacs mode meta keymap.  The  remain-
-       ing  characters are unbound, which causes readline to ring
-       the  bell  (subject  to  the  setting  of  the  bbeellll--ssttyyllee

-<P>
-The following paragraphs describe the notation used to represent
-keystrokes.
-
-</P>
-<P>
-The text <KBD>C-k</KBD> is read as `Control-K' and describes the character
-produced when the <KBD>k</KBD> key is pressed while the Control key
-is depressed.
-
-</P>
-<P>
-The text <KBD>M-k</KBD> is read as `Meta-K' and describes the character
-produced when the Meta key (if you have one) is depressed, and the <KBD>k</KBD>
-key is pressed.
-The Meta key is labeled <KBD>ALT</KBD> on many keyboards.
-On keyboards with two keys labeled <KBD>ALT</KBD> (usually to either side of
-the space bar), the <KBD>ALT</KBD> on the left side is generally set to
-work as a Meta key.
-The <KBD>ALT</KBD> key on the right may also be configured to work as a
-Meta key or may be configured as some other modifier, such as a
-Compose key for typing accented characters.
-
-</P>
-<P>
-If you do not have a Meta or <KBD>ALT</KBD> key, or another key working as
-a Meta key, the identical keystroke can be generated by typing <KBD>ESC</KBD>
-<I>first</I>, and then typing <KBD>k</KBD>.
-Either process is known as <EM>metafying</EM> the <KBD>k</KBD> key.
-
-</P>
-<P>
-The text <KBD>M-C-k</KBD> is read as `Meta-Control-k' and describes the
-character produced by <EM>metafying</EM> <KBD>C-k</KBD>.
-
-</P>
-<P>
-In addition, several keys have their own names.  Specifically,
-<KBD>DEL</KBD>, <KBD>ESC</KBD>, <KBD>LFD</KBD>, <KBD>SPC</KBD>, <KBD>RET</KBD>, and <KBD>TAB</KBD> all
-stand for themselves when seen in this text, or in an init file
-(see section <A HREF="readline.html#SEC9">Readline Init File</A>).
-If your keyboard lacks a <KBD>LFD</KBD> key, typing <KBD>C-j</KBD> will
-produce the desired character.
-The <KBD>RET</KBD> key may be labeled <KBD>Return</KBD> or <KBD>Enter</KBD> on
-some keyboards.

-Often during an interactive session you type in a long line of text,
-only to notice that the first word on the line is misspelled.  The
-Readline library gives you a set of commands for manipulating the text
-as you type it in, allowing you to just fix your typo, and not forcing
-you to retype the majority of the line.  Using these editing commands,
-you move the cursor to the place that needs correction, and delete or
-insert the text of the corrections.  Then, when you are satisfied with
-the line, you simply press <KBD>RETURN</KBD>.  You do not have to be at the
-end of the line to press <KBD>RETURN</KBD>; the entire line is accepted
-regardless of the location of the cursor within the line.

-In order to enter characters into the line, simply type them.  The typed
-character appears where the cursor was, and then the cursor moves one
-space to the right.  If you mistype a character, you can use your
-erase character to back up and delete the mistyped character.
-
-</P>
-<P>
-Sometimes you may mistype a character, and
-not notice the error until you have typed several other characters.  In
-that case, you can type <KBD>C-b</KBD> to move the cursor to the left, and then
-correct your mistake.  Afterwards, you can move the cursor to the right
-with <KBD>C-f</KBD>.
-
-</P>
-<P>
-When you add text in the middle of a line, you will notice that characters
-to the right of the cursor are `pushed over' to make room for the text
-that you have inserted.  Likewise, when you delete text behind the cursor,
-characters to the right of the cursor are `pulled back' to fill in the
-blank space created by the removal of the text.  A list of the bare
-essentials for editing the text of an input line follows.

-</P>
-<P>
-<EM>Killing</EM> text means to delete the text from the line, but to save
-it away for later use, usually by <EM>yanking</EM> (re-inserting)
-it back into the line.
-(`Cut' and `paste' are more recent jargon for `kill' and `yank'.)
-
-</P>
-<P>
-If the description for a command says that it `kills' text, then you can
-be sure that you can get the text back in a different (or the same)
-place later.
-
-</P>
-<P>
-When you use a kill command, the text is saved in a <EM>kill-ring</EM>.
-Any number of consecutive kills save all of the killed text together, so
-that when you yank it back, you get it all.  The kill
-ring is not line specific; the text that you killed on a previously
-typed line is available to be yanked back later, when you are typing
-another line.
-<A NAME="IDX7"></A>
-
-</P>
-<P>
-Here is the list of commands for killing text.
-
-</P>
-<DL COMPACT>
-
-<DT><KBD>C-k</KBD>
-<DD>
-Kill the text from the current cursor position to the end of the line.
-
-<DT><KBD>M-d</KBD>
-<DD>
-Kill from the cursor to the end of the current word, or, if between
-words, to the end of the next word.
-Word boundaries are the same as those used by <KBD>M-f</KBD>.
-
-<DT><KBD>M-DEL</KBD>
-<DD>
-Kill from the cursor the start of the previous word, or, if between
-words, to the start of the previous word.
-Word boundaries are the same as those used by <KBD>M-b</KBD>.
-
-<DT><KBD>C-w</KBD>
-<DD>
-Kill from the cursor to the previous whitespace.  This is different than
-<KBD>M-DEL</KBD> because the word boundaries differ.
-
-</DL>
-
-<P>
-Here is how to <EM>yank</EM> the text back into the line.  Yanking
-means to copy the most-recently-killed text from the kill buffer.
-
-</P>
-<DL COMPACT>
-
-<DT><KBD>C-y</KBD>
-<DD>
-Yank the most recently killed text back into the buffer at the cursor.
-
-<DT><KBD>M-y</KBD>
-<DD>
-Rotate the kill-ring, and yank the new top.  You can only do this if
-the prior command is <KBD>C-y</KBD> or <KBD>M-y</KBD>.
-</DL>
-
-
-
-<H3><A NAME="SEC7" HREF="readline.html#TOC7">Readline Arguments</A></H3>
-
-<P>
-You can pass numeric arguments to Readline commands.  Sometimes the
-argument acts as a repeat count, other times it is the <I>sign</I> of the
-argument that is significant.  If you pass a negative argument to a
-command which normally acts in a forward direction, that command will
-act in a backward direction.  For example, to kill text back to the
-start of the line, you might type <SAMP>`M-- C-k'</SAMP>.
-
-</P>
-<P>
-The general way to pass numeric arguments to a command is to type meta
-digits before the command.  If the first `digit' typed is a minus
-sign (<SAMP>`-'</SAMP>), then the sign of the argument will be negative.  Once
-you have typed one meta digit to get the argument started, you can type
-the remainder of the digits, and then the command.  For example, to give
-the <KBD>C-d</KBD> command an argument of 10, you could type <SAMP>`M-1 0 C-d'</SAMP>.
-
-</P>
-
-
-<H3><A NAME="SEC8" HREF="readline.html#TOC8">Searching for Commands in the History</A></H3>
-
-<P>
-Readline provides commands for searching through the command history
-for lines containing a specified string.
-There are two search modes:  <VAR>incremental</VAR> and <VAR>non-incremental</VAR>.
-
-</P>
-<P>
-Incremental searches begin before the user has finished typing the
-search string.
-As each character of the search string is typed, Readline displays
-the next entry from the history matching the string typed so far.
-An incremental search requires only as many characters as needed to
-find the desired history entry.
-To search backward in the history for a particular string, type
-<KBD>C-r</KBD>.  Typing <KBD>C-s</KBD> searches forward through the history.
-The characters present in the value of the <CODE>isearch-terminators</CODE> variable
-are used to terminate an incremental search.
-If that variable has not been assigned a value, the <KBD>ESC</KBD> and
-<KBD>C-J</KBD> characters will terminate an incremental search.
-<KBD>C-g</KBD> will abort an incremental search and restore the original line.
-When the search is terminated, the history entry containing the
-search string becomes the current line.
-
-</P>
-<P>
-To find other matching entries in the history list, type <KBD>C-r</KBD> or
-<KBD>C-s</KBD> as appropriate.
-This will search backward or forward in the history for the next
-entry matching the search string typed so far.
-Any other key sequence bound to a Readline command will terminate
-the search and execute that command.
-For instance, a <KBD>RET</KBD> will terminate the search and accept
-the line, thereby executing the command from the history list.
-
-</P>
-<P>
-Non-incremental searches read the entire search string before starting
-to search for matching history lines.  The search string may be
-typed by the user or be part of the contents of the current line.

-<P>
-Although the Readline library comes with a set of Emacs-like
-keybindings installed by default, it is possible to use a different set
-of keybindings.
-Any user can customize programs that use Readline by putting
-commands in an <EM>inputrc</EM> file, conventionally in his home directory.
-The name of this
-file is taken from the value of the environment variable <CODE>INPUTRC</CODE>.  If
-that variable is unset, the default is <TT>`~/.inputrc'</TT>.
-

-<DT>Variable Settings
-<DD>
-You can modify the run-time behavior of Readline by
-altering the values of variables in Readline
-using the <CODE>set</CODE> command within the init file.  Here is how to
-change from the default Emacs-like key binding to use
-<CODE>vi</CODE> line editing commands:
-
-
-<PRE>
-set editing-mode vi
-</PRE>
-
-A great deal of run-time behavior is changeable with the following
-variables.
-
-<DL COMPACT>
-
-<DT><CODE>bell-style</CODE>
-<DD>
-<A NAME="IDX9"></A>
-Controls what happens when Readline wants to ring the terminal bell.
-If set to <SAMP>`none'</SAMP>, Readline never rings the bell.  If set to
-<SAMP>`visible'</SAMP>, Readline uses a visible bell if one is available.
-If set to <SAMP>`audible'</SAMP> (the default), Readline attempts to ring
-the terminal's bell.
-
-<DT><CODE>comment-begin</CODE>
-<DD>
-<A NAME="IDX10"></A>
-The string to insert at the beginning of the line when the
-<CODE>insert-comment</CODE> command is executed.  The default value
-is <CODE>"#"</CODE>.
-
-<DT><CODE>completion-ignore-case</CODE>
-<DD>
-If set to <SAMP>`on'</SAMP>, Readline performs filename matching and completion
-in a case-insensitive fashion.
-The default value is <SAMP>`off'</SAMP>.
-
-<DT><CODE>completion-query-items</CODE>
-<DD>
-<A NAME="IDX11"></A>
-The number of possible completions that determines when the user is
-asked whether he wants to see the list of possibilities.  If the
-number of possible completions is greater than this value,
-Readline will ask the user whether or not he wishes to view
-them; otherwise, they are simply listed.  The default limit is
-<CODE>100</CODE>.
-
-<DT><CODE>convert-meta</CODE>
-<DD>
-<A NAME="IDX12"></A>
-If set to <SAMP>`on'</SAMP>, Readline will convert characters with the
-eighth bit set to an ASCII key sequence by stripping the eighth
-bit and prefixing an <KBD>ESC</KBD> character, converting them to a
-meta-prefixed key sequence.  The default value is <SAMP>`on'</SAMP>.
-
-<DT><CODE>disable-completion</CODE>
-<DD>
-<A NAME="IDX13"></A>
-If set to <SAMP>`On'</SAMP>, Readline will inhibit word completion.
-Completion  characters will be inserted into the line as if they had
-been mapped to <CODE>self-insert</CODE>.  The default is <SAMP>`off'</SAMP>.
-
-<DT><CODE>editing-mode</CODE>
-<DD>
-<A NAME="IDX14"></A>
-The <CODE>editing-mode</CODE> variable controls which default set of
-key bindings is used.  By default, Readline starts up in Emacs editing
-mode, where the keystrokes are most similar to Emacs.  This variable can be
-set to either <SAMP>`emacs'</SAMP> or <SAMP>`vi'</SAMP>.
-
-<DT><CODE>enable-keypad</CODE>
-<DD>
-<A NAME="IDX15"></A>
-When set to <SAMP>`on'</SAMP>, Readline will try to enable the application
-keypad when it is called.  Some systems need this to enable the
-arrow keys.  The default is <SAMP>`off'</SAMP>.
-
-<DT><CODE>expand-tilde</CODE>
-<DD>
-<A NAME="IDX16"></A>
-If set to <SAMP>`on'</SAMP>, tilde expansion is performed when Readline
-attempts word completion.  The default is <SAMP>`off'</SAMP>.
-
-<DT><CODE>horizontal-scroll-mode</CODE>
-<DD>
-<A NAME="IDX17"></A>
-This variable can be set to either <SAMP>`on'</SAMP> or <SAMP>`off'</SAMP>.  Setting it
-to <SAMP>`on'</SAMP> means that the text of the lines being edited will scroll
-horizontally on a single screen line when they are longer than the width
-of the screen, instead of wrapping onto a new screen line.  By default,
-this variable is set to <SAMP>`off'</SAMP>.
-
-<DT><CODE>input-meta</CODE>
-<DD>
-<A NAME="IDX18"></A>
-<A NAME="IDX19"></A>
-If set to <SAMP>`on'</SAMP>, Readline will enable eight-bit input (it
-will not strip the eighth bit from the characters it reads),
-regardless of what the terminal claims it can support.  The
-default value is <SAMP>`off'</SAMP>.  The name <CODE>meta-flag</CODE> is a
-synonym for this variable.
-
-<DT><CODE>isearch-terminators</CODE>
-<DD>
-<A NAME="IDX20"></A>
-The string of characters that should terminate an incremental search without
-subsequently executing the character as a command (see section <A HREF="readline.html#SEC8">Searching for Commands in the History</A>).
-If this variable has not been given a value, the characters <KBD>ESC</KBD> and
-<KBD>C-J</KBD> will terminate an incremental search.
-
-<DT><CODE>keymap</CODE>
-<DD>
-<A NAME="IDX21"></A>
-Sets Readline's idea of the current keymap for key binding commands.
-Acceptable <CODE>keymap</CODE> names are
-<CODE>emacs</CODE>,
-<CODE>emacs-standard</CODE>,
-<CODE>emacs-meta</CODE>,
-<CODE>emacs-ctlx</CODE>,
-<CODE>vi</CODE>,

-<DT>Key Bindings
-<DD>
-The syntax for controlling key bindings in the init file is
-simple.  First you need to find the name of the command that you
-want to change.  The following sections contain tables of the command
-name, the default keybinding, if any, and a short description of what
-the command does.
-
-Once you know the name of the command, simply place the name of the key
-you wish to bind the command to, a colon, and then the name of the
-command on a line in the init file.  The name of the key
-can be expressed in different ways, depending on which is most
-comfortable for you.
-
-<DL COMPACT>
-
-<DT><VAR>keyname</VAR>: <VAR>function-name</VAR> or <VAR>macro</VAR>
-<DD>
-<VAR>keyname</VAR> is the name of a key spelled out in English.  For example:
-
-<PRE>
-Control-u: universal-argument
-Meta-Rubout: backward-kill-word
-Control-o: "&#62; output"
-</PRE>
-
-In the above example, <KBD>C-u</KBD> is bound to the function
-<CODE>universal-argument</CODE>, and <KBD>C-o</KBD> is bound to run the macro
-expressed on the right hand side (that is, to insert the text
-<SAMP>`&#62; output'</SAMP> into the line).
-
-<DT>"<VAR>keyseq</VAR>": <VAR>function-name</VAR> or <VAR>macro</VAR>
-<DD>
-<VAR>keyseq</VAR> differs from <VAR>keyname</VAR> above in that strings
-denoting an entire key sequence can be specified, by placing
-the key sequence in double quotes.  Some GNU Emacs style key
-escapes can be used, as in the following example, but the
-special character names are not recognized.
-
-
-<PRE>
-"\C-u": universal-argument
-"\C-x\C-r": re-read-init-file
-"\e[11~": "Function Key 1"
-</PRE>
-
-In the above example, <KBD>C-u</KBD> is bound to the function
-<CODE>universal-argument</CODE> (just as it was in the first example),
-<SAMP>`<KBD>C-x</KBD> <KBD>C-r</KBD>'</SAMP> is bound to the function <CODE>re-read-init-file</CODE>,
-and <SAMP>`<KBD>ESC</KBD> <KBD>[</KBD> <KBD>1</KBD> <KBD>1</KBD> <KBD>~</KBD>'</SAMP> is bound to insert
-the text <SAMP>`Function Key 1'</SAMP>.
-
-</DL>
-
-The following GNU Emacs style escape sequences are available when
-specifying key sequences:
-
-<DL COMPACT>
-
-<DT><CODE><KBD>\C-</KBD></CODE>
-<DD>
-control prefix
-<DT><CODE><KBD>\M-</KBD></CODE>
-<DD>
-meta prefix
-<DT><CODE><KBD>\e</KBD></CODE>
-<DD>
-an escape character
-<DT><CODE><KBD>\\</KBD></CODE>
-<DD>
-backslash
-<DT><CODE><KBD>\"</KBD></CODE>
-<DD>
-<KBD>"</KBD>, a double quotation mark
-<DT><CODE><KBD>\'</KBD></CODE>
-<DD>
-<KBD>'</KBD>, a single quote or apostrophe
-</DL>
-
-In addition to the GNU Emacs style escape sequences, a second
-set of backslash escapes is available:
-
-<DL COMPACT>
-
-<DT><CODE>\a</CODE>
-<DD>
-alert (bell)
-<DT><CODE>\b</CODE>
-<DD>
-backspace
-<DT><CODE>\d</CODE>
-<DD>
-delete
-<DT><CODE>\f</CODE>
-<DD>
-form feed
-<DT><CODE>\n</CODE>
-<DD>
-newline
-<DT><CODE>\r</CODE>
-<DD>
-carriage return
-<DT><CODE>\t</CODE>
-<DD>
-horizontal tab
-<DT><CODE>\v</CODE>
-<DD>
-vertical tab
-<DT><CODE>\<VAR>nnn</VAR></CODE>
-<DD>
-the character whose <CODE>ASCII</CODE> code is the octal value <VAR>nnn</VAR>
-(one to three digits)
-<DT><CODE>\x<VAR>nnn</VAR></CODE>
-<DD>
-the character whose <CODE>ASCII</CODE> code is the hexadecimal value <VAR>nnn</VAR>
-(one to three digits)
-</DL>
-
-When entering the text of a macro, single or double quotes must
-be used to indicate a macro definition.
-Unquoted text is assumed to be a function name.
-In the macro body, the backslash escapes described above are expanded.
-Backslash will quote any other character in the macro text,
-including <SAMP>`"'</SAMP> and <SAMP>`''</SAMP>.
-For example, the following binding will make <SAMP>`C-x \'</SAMP>
-insert a single <SAMP>`\'</SAMP> into the line:
-
-<PRE>
-"\C-x\\": "\\"

-<H3><A NAME="SEC11" HREF="readline.html#TOC11">Conditional Init Constructs</A></H3>
-
-<P>
-Readline implements a facility similar in spirit to the conditional
-compilation features of the C preprocessor which allows key
-bindings and variable settings to be performed as the result
-of tests.  There are four parser directives used.
-
-</P>
-<DL COMPACT>
-
-<DT><CODE>$if</CODE>
-<DD>
-The <CODE>$if</CODE> construct allows bindings to be made based on the
-editing mode, the terminal being used, or the application using
-Readline.  The text of the test extends to the end of the line;
-no characters are required to isolate it.
-
-<DL COMPACT>
-
-<DT><CODE>mode</CODE>
-<DD>
-The <CODE>mode=</CODE> form of the <CODE>$if</CODE> directive is used to test
-whether Readline is in <CODE>emacs</CODE> or <CODE>vi</CODE> mode.
-This may be used in conjunction
-with the <SAMP>`set keymap'</SAMP> command, for instance, to set bindings in
-the <CODE>emacs-standard</CODE> and <CODE>emacs-ctlx</CODE> keymaps only if
-Readline is starting out in <CODE>emacs</CODE> mode.
-
-<DT><CODE>term</CODE>
-<DD>
-The <CODE>term=</CODE> form may be used to include terminal-specific
-key bindings, perhaps to bind the key sequences output by the
-terminal's function keys.  The word on the right side of the
-<SAMP>`='</SAMP> is tested against both the full name of the terminal and
-the portion of the terminal name before the first <SAMP>`-'</SAMP>.  This
-allows <CODE>sun</CODE> to match both <CODE>sun</CODE> and <CODE>sun-cmd</CODE>,
-for instance.
-
-<DT><CODE>application</CODE>
-<DD>
-The <VAR>application</VAR> construct is used to include
-application-specific settings.  Each program using the Readline
-library sets the <VAR>application name</VAR>, and you can test for it. 
-This could be used to bind key sequences to functions useful for
-a specific program.  For instance, the following command adds a
-key sequence that quotes the current or previous word in Bash:
-
-<PRE>
-$if Bash
-# Quote the current or previous word
-"\C-xq": "\eb\"\ef\""
-$endif
-</PRE>
-
-</DL>
-
-<DT><CODE>$endif</CODE>
-<DD>
-This command, as seen in the previous example, terminates an
-<CODE>$if</CODE> command.
-
-<DT><CODE>$else</CODE>
-<DD>
-Commands in this branch of the <CODE>$if</CODE> directive are executed if
-the test fails.
-
-<DT><CODE>$include</CODE>
-<DD>
-This directive takes a single filename as an argument and reads commands
-and bindings from that file.

-<H2><A NAME="SEC40" HREF="readline.html#TOC40">Readline Signal Handling</A></H2>
-
-<P>
-Signals are asynchronous events sent to a process by the Unix kernel,
-sometimes on behalf of another process.  They are intended to indicate
-exceptional events, like a user pressing the interrupt key on his
-terminal, or a network connection being broken.  There is a class of
-signals that can be sent to the process currently reading input from
-the keyboard.  Since Readline changes the terminal attributes when it
-is called, it needs to perform special processing when a signal is
-received to restore the terminal to a sane state, or provide application
-writers with functions to do so manually.
-
-</P>
-<P>
-Readline contains an internal signal handler that is installed for a
-number of signals (<CODE>SIGINT</CODE>, <CODE>SIGQUIT</CODE>, <CODE>SIGTERM</CODE>,
-<CODE>SIGALRM</CODE>, <CODE>SIGTSTP</CODE>, <CODE>SIGTTIN</CODE>, and <CODE>SIGTTOU</CODE>).
-When one of these signals is received, the signal handler
-will reset the terminal attributes to those that were in effect before
-<CODE>readline ()</CODE> was called, reset the signal handling to what it was
-before <CODE>readline ()</CODE> was called, and resend the signal to the calling
-application.
-If and when the calling application's signal handler returns, Readline
-will reinitialize the terminal and continue to accept input.
-When a <CODE>SIGINT</CODE> is received, the Readline signal handler performs
-some additional work, which will cause any partially-entered line to be
-aborted (see the description of <CODE>rl_free_line_state ()</CODE>).
-
-</P>
-<P>
-There is an additional Readline signal handler, for <CODE>SIGWINCH</CODE>, which
-the kernel sends to a process whenever the terminal's size changes (for
-example, if a user resizes an <CODE>xterm</CODE>).  The Readline <CODE>SIGWINCH</CODE>
-handler updates Readline's internal screen size state, and then calls any
-<CODE>SIGWINCH</CODE> signal handler the calling application has installed. 
-Readline calls the application's <CODE>SIGWINCH</CODE> signal handler without
-resetting the terminal to its original state.  If the application's signal
-handler does more than update its idea of the terminal size and return (for
-example, a <CODE>longjmp</CODE> back to a main processing loop), it <EM>must</EM>
-call <CODE>rl_cleanup_after_signal ()</CODE> (described below), to restore the
-terminal state. 
-
-</P>
-<P>
-Readline provides two variables that allow application writers to
-control whether or not it will catch certain signals and act on them
-when they are received.  It is important that applications change the
-values of these variables only when calling <CODE>readline ()</CODE>, not in
-a signal handler, so Readline's internal signal state is not corrupted.

-In order to complete some text, the full list of possible completions
-must be available.  That is, it is not possible to accurately
-expand a partial word without knowing all of the possible words
-which make sense in that context.  The Readline library provides
-the user interface to completion, and two of the most common
-completion functions:  filename and username.  For completing other types
-of text, you must write your own completion function.  This section
-describes exactly what such functions must do, and provides an example.
-
-</P>
-<P>
-There are three major functions used to perform completion:
-
-</P>
-
-<OL>
-<LI>
-
-The user-interface function <CODE>rl_complete ()</CODE>.  This function is
-called with the same arguments as other Readline
-functions intended for interactive use:  <VAR>count</VAR> and
-<VAR>invoking_key</VAR>.  It isolates the word to be completed and calls
-<CODE>completion_matches ()</CODE> to generate a list of possible completions.
-It then either lists the possible completions, inserts the possible
-completions, or actually performs the
-completion, depending on which behavior is desired.
-
-<LI>
-
-The internal function <CODE>completion_matches ()</CODE> uses your
-<EM>generator</EM> function to generate the list of possible matches, and
-then returns the array of these matches.  You should place the address
-of your generator function in <CODE>rl_completion_entry_function</CODE>.
-
-<LI>
-
-The generator function is called repeatedly from
-<CODE>completion_matches ()</CODE>, returning a string each time.  The
-arguments to the generator function are <VAR>text</VAR> and <VAR>state</VAR>.
-<VAR>text</VAR> is the partial word to be completed.  <VAR>state</VAR> is zero the
-first time the function is called, allowing the generator to perform
-any necessary initialization, and a positive non-zero integer for
-each subsequent call.  When the generator function returns
-<CODE>(char *)NULL</CODE> this signals <CODE>completion_matches ()</CODE> that there are
-no more possibilities left.  Usually the generator function computes the
-list of possible completions when <VAR>state</VAR> is zero, and returns them
-one at a time on subsequent calls.  Each string the generator function
-returns as a match must be allocated with <CODE>malloc()</CODE>; Readline
-frees the strings when it has finished with them.

-Introduction to Line Editing
-============================
-
-   The following paragraphs describe the notation used to represent
-keystrokes.
-
-   The text <C-k> is read as `Control-K' and describes the character
-produced when the <k> key is pressed while the Control key is depressed.
-
-   The text <M-k> is read as `Meta-K' and describes the character
-produced when the Meta key (if you have one) is depressed, and the <k>
-key is pressed.  The Meta key is labeled <ALT> on many keyboards.  On
-keyboards with two keys labeled <ALT> (usually to either side of the
-space bar), the <ALT> on the left side is generally set to work as a
-Meta key.  The <ALT> key on the right may also be configured to work as
-a Meta key or may be configured as some other modifier, such as a
-Compose key for typing accented characters.
-
-   If you do not have a Meta or <ALT> key, or another key working as a
-Meta key, the identical keystroke can be generated by typing <ESC>
-first, and then typing <k>.  Either process is known as "metafying" the
-<k> key.
-
-   The text <M-C-k> is read as `Meta-Control-k' and describes the
-character produced by "metafying" <C-k>.
-
-   In addition, several keys have their own names.  Specifically,
-<DEL>, <ESC>, <LFD>, <SPC>, <RET>, and <TAB> all stand for themselves
-when seen in this text, or in an init file (*note Readline Init
-File::.).  If your keyboard lacks a <LFD> key, typing <C-j> will
-produce the desired character.  The <RET> key may be labeled <Return>
-or <Enter> on some keyboards.

-Readline Interaction
-====================
-
-   Often during an interactive session you type in a long line of text,
-only to notice that the first word on the line is misspelled.  The
-Readline library gives you a set of commands for manipulating the text
-as you type it in, allowing you to just fix your typo, and not forcing
-you to retype the majority of the line.  Using these editing commands,
-you move the cursor to the place that needs correction, and delete or
-insert the text of the corrections.  Then, when you are satisfied with
-the line, you simply press <RETURN>.  You do not have to be at the end
-of the line to press <RETURN>; the entire line is accepted regardless
-of the location of the cursor within the line.

-Readline Bare Essentials
-------------------------
-
-   In order to enter characters into the line, simply type them.  The
-typed character appears where the cursor was, and then the cursor moves
-one space to the right.  If you mistype a character, you can use your
-erase character to back up and delete the mistyped character.
-
-   Sometimes you may mistype a character, and not notice the error
-until you have typed several other characters.  In that case, you can
-type <C-b> to move the cursor to the left, and then correct your
-mistake.  Afterwards, you can move the cursor to the right with <C-f>.
-
-   When you add text in the middle of a line, you will notice that
-characters to the right of the cursor are `pushed over' to make room
-for the text that you have inserted.  Likewise, when you delete text
-behind the cursor, characters to the right of the cursor are `pulled
-back' to fill in the blank space created by the removal of the text.  A
-list of the bare essentials for editing the text of an input line
-follows.
-
-<C-b>
-     Move back one character.
-
-<C-f>
-     Move forward one character.
-
-<DEL> or <Backspace>
-     Delete the character to the left of the cursor.
-
-<C-d>
-     Delete the character underneath the cursor.
-
-Printing characters
-     Insert the character into the line at the cursor.
-
-<C-_> or <C-x C-u>
-     Undo the last editing command.  You can undo all the way back to an
-     empty line.
-
-(Depending on your configuration, the <Backspace> key be set to delete
-the character to the left of the cursor and the <DEL> key set to delete
-the character underneath the cursor, like <C-d>, rather than the
-character to the left of the cursor.)

-
-Readline Movement Commands
---------------------------
-
-   The above table describes the most basic keystrokes that you need in
-order to do editing of the input line.  For your convenience, many
-other commands have been added in addition to <C-b>, <C-f>, <C-d>, and
-<DEL>.  Here are some commands for moving more rapidly about the line.
-
-<C-a>
-     Move to the start of the line.
-
-<C-e>
-     Move to the end of the line.
-
-<M-f>
-     Move forward a word, where a word is composed of letters and
-     digits.
-
-<M-b>
-     Move backward a word.
-
-<C-l>
-     Clear the screen, reprinting the current line at the top.
-
-   Notice how <C-f> moves forward a character, while <M-f> moves
-forward a word.  It is a loose convention that control keystrokes
-operate on characters while meta keystrokes operate on words.

-
-Readline Killing Commands
--------------------------
-
-   "Killing" text means to delete the text from the line, but to save
-it away for later use, usually by "yanking" (re-inserting) it back into
-the line.  (`Cut' and `paste' are more recent jargon for `kill' and
-`yank'.)
-
-   If the description for a command says that it `kills' text, then you
-can be sure that you can get the text back in a different (or the same)
-place later.
-
-   When you use a kill command, the text is saved in a "kill-ring".
-Any number of consecutive kills save all of the killed text together, so
-that when you yank it back, you get it all.  The kill ring is not line
-specific; the text that you killed on a previously typed line is
-available to be yanked back later, when you are typing another line.
-
-   Here is the list of commands for killing text.
-
-<C-k>
-     Kill the text from the current cursor position to the end of the
-     line.
-
-<M-d>
-     Kill from the cursor to the end of the current word, or, if between
-     words, to the end of the next word.  Word boundaries are the same
-     as those used by <M-f>.
-
-<M-DEL>
-     Kill from the cursor the start of the previous word, or, if between
-     words, to the start of the previous word.  Word boundaries are the
-     same as those used by <M-b>.
-
-<C-w>
-     Kill from the cursor to the previous whitespace.  This is
-     different than <M-DEL> because the word boundaries differ.
-
-   Here is how to "yank" the text back into the line.  Yanking means to
-copy the most-recently-killed text from the kill buffer.
-
-<C-y>
-     Yank the most recently killed text back into the buffer at the
-     cursor.
-
-<M-y>
-     Rotate the kill-ring, and yank the new top.  You can only do this
-     if the prior command is <C-y> or <M-y>.
-

-
-Readline Arguments
-------------------
-
-   You can pass numeric arguments to Readline commands.  Sometimes the
-argument acts as a repeat count, other times it is the sign of the
-argument that is significant.  If you pass a negative argument to a
-command which normally acts in a forward direction, that command will
-act in a backward direction.  For example, to kill text back to the
-start of the line, you might type `M-- C-k'.
-
-   The general way to pass numeric arguments to a command is to type
-meta digits before the command.  If the first `digit' typed is a minus
-sign (`-'), then the sign of the argument will be negative.  Once you
-have typed one meta digit to get the argument started, you can type the
-remainder of the digits, and then the command.  For example, to give
-the <C-d> command an argument of 10, you could type `M-1 0 C-d'.
-
-
-File: readline.info,  Node: Searching,  Prev: Readline Arguments,  Up: Readline Interaction
-
-Searching for Commands in the History
--------------------------------------
-
-   Readline provides commands for searching through the command history
-for lines containing a specified string.  There are two search modes:
-INCREMENTAL and NON-INCREMENTAL.
-
-   Incremental searches begin before the user has finished typing the
-search string.  As each character of the search string is typed,
-Readline displays the next entry from the history matching the string
-typed so far.  An incremental search requires only as many characters
-as needed to find the desired history entry.  To search backward in the
-history for a particular string, type <C-r>.  Typing <C-s> searches
-forward through the history.  The characters present in the value of
-the `isearch-terminators' variable are used to terminate an incremental
-search.  If that variable has not been assigned a value, the <ESC> and
-<C-J> characters will terminate an incremental search.  <C-g> will
-abort an incremental search and restore the original line.  When the
-search is terminated, the history entry containing the search string
-becomes the current line.
-
-   To find other matching entries in the history list, type <C-r> or
-<C-s> as appropriate.  This will search backward or forward in the
-history for the next entry matching the search string typed so far.
-Any other key sequence bound to a Readline command will terminate the
-search and execute that command.  For instance, a <RET> will terminate
-the search and accept the line, thereby executing the command from the
-history list.
-
-   Non-incremental searches read the entire search string before
-starting to search for matching history lines.  The search string may be
-typed by the user or be part of the contents of the current line.

-Readline Init File
-==================
-
-   Although the Readline library comes with a set of Emacs-like
-keybindings installed by default, it is possible to use a different set
-of keybindings.  Any user can customize programs that use Readline by
-putting commands in an "inputrc" file, conventionally in his home
-directory.  The name of this file is taken from the value of the
-environment variable `INPUTRC'.  If that variable is unset, the default
-is `~/.inputrc'.
-
-   When a program which uses the Readline library starts up, the init
-file is read, and the key bindings are set.
-
-   In addition, the `C-x C-r' command re-reads this init file, thus
-incorporating any changes that you might have made to it.

-
-* Readline Init File Syntax::	Syntax for the commands in the inputrc file.

-
-* Sample Init File::		An example inputrc file.
-
-
-File: readline.info,  Node: Readline Init File Syntax,  Next: Conditional Init Constructs,  Up: Readline Init File
-
-Readline Init File Syntax
--------------------------
-
-   There are only a few basic constructs allowed in the Readline init
-file.  Blank lines are ignored.  Lines beginning with a `#' are
-comments.  Lines beginning with a `$' indicate conditional constructs
-(*note Conditional Init Constructs::.).  Other lines denote variable
-settings and key bindings.
-
-Variable Settings
-     You can modify the run-time behavior of Readline by altering the
-     values of variables in Readline using the `set' command within the
-     init file.  Here is how to change from the default Emacs-like key
-     binding to use `vi' line editing commands:
-
-          set editing-mode vi
-
-     A great deal of run-time behavior is changeable with the following
-     variables.
-
-    `bell-style'
-          Controls what happens when Readline wants to ring the
-          terminal bell.  If set to `none', Readline never rings the
-          bell.  If set to `visible', Readline uses a visible bell if
-          one is available.  If set to `audible' (the default),
-          Readline attempts to ring the terminal's bell.
-
-    `comment-begin'
-          The string to insert at the beginning of the line when the
-          `insert-comment' command is executed.  The default value is
-          `"#"'.
-
-    `completion-ignore-case'
-          If set to `on', Readline performs filename matching and
-          completion in a case-insensitive fashion.  The default value
-          is `off'.
-
-    `completion-query-items'
-          The number of possible completions that determines when the
-          user is asked whether he wants to see the list of
-          possibilities.  If the number of possible completions is
-          greater than this value, Readline will ask the user whether
-          or not he wishes to view them; otherwise, they are simply
-          listed.  The default limit is `100'.
-
-    `convert-meta'
-          If set to `on', Readline will convert characters with the
-          eighth bit set to an ASCII key sequence by stripping the
-          eighth bit and prefixing an <ESC> character, converting them
-          to a meta-prefixed key sequence.  The default value is `on'.
-
-    `disable-completion'
-          If set to `On', Readline will inhibit word completion.
-          Completion  characters will be inserted into the line as if
-          they had been mapped to `self-insert'.  The default is `off'.
-
-    `editing-mode'
-          The `editing-mode' variable controls which default set of key
-          bindings is used.  By default, Readline starts up in Emacs
-          editing mode, where the keystrokes are most similar to Emacs.
-          This variable can be set to either `emacs' or `vi'.
-
-    `enable-keypad'
-          When set to `on', Readline will try to enable the application
-          keypad when it is called.  Some systems need this to enable
-          the arrow keys.  The default is `off'.
-
-    `expand-tilde'
-          If set to `on', tilde expansion is performed when Readline
-          attempts word completion.  The default is `off'.
-
-    `horizontal-scroll-mode'
-          This variable can be set to either `on' or `off'.  Setting it
-          to `on' means that the text of the lines being edited will
-          scroll horizontally on a single screen line when they are
-          longer than the width of the screen, instead of wrapping onto
-          a new screen line.  By default, this variable is set to `off'.
-
-    `input-meta'
-          If set to `on', Readline will enable eight-bit input (it will
-          not strip the eighth bit from the characters it reads),
-          regardless of what the terminal claims it can support.  The
-          default value is `off'.  The name `meta-flag' is a synonym
-          for this variable.
-
-    `isearch-terminators'
-          The string of characters that should terminate an incremental
-          search without subsequently executing the character as a
-          command (*note Searching::.).  If this variable has not been
-          given a value, the characters <ESC> and <C-J> will terminate
-          an incremental search.
-
-    `keymap'
-          Sets Readline's idea of the current keymap for key binding
-          commands.  Acceptable `keymap' names are `emacs',
-          `emacs-standard', `emacs-meta', `emacs-ctlx', `vi',
-          `vi-command', and `vi-insert'.  `vi' is equivalent to
-          `vi-command'; `emacs' is equivalent to `emacs-standard'.  The
-          default value is `emacs'.  The value of the `editing-mode'
-          variable also affects the default keymap.
-
-    `mark-directories'
-          If set to `on', completed directory names have a slash
-          appended.  The default is `on'.
-
-    `mark-modified-lines'
-          This variable, when set to `on', causes Readline to display an
-          asterisk (`*') at the start of history lines which have been
-          modified.  This variable is `off' by default.
-
-    `output-meta'
-          If set to `on', Readline will display characters with the
-          eighth bit set directly rather than as a meta-prefixed escape
-          sequence.  The default is `off'.
-
-    `print-completions-horizontally'
-          If set to `on', Readline will display completions with matches
-          sorted horizontally in alphabetical order, rather than down
-          the screen.  The default is `off'.
-
-    `show-all-if-ambiguous'
-          This alters the default behavior of the completion functions.
-          If set to `on', words which have more than one possible
-          completion cause the matches to be listed immediately instead
-          of ringing the bell.  The default value is `off'.
-
-    `visible-stats'
-          If set to `on', a character denoting a file's type is
-          appended to the filename when listing possible completions.
-          The default is `off'.
-
-Key Bindings
-     The syntax for controlling key bindings in the init file is
-     simple.  First you need to find the name of the command that you
-     want to change.  The following sections contain tables of the
-     command name, the default keybinding, if any, and a short
-     description of what the command does.
-
-     Once you know the name of the command, simply place the name of
-     the key you wish to bind the command to, a colon, and then the
-     name of the command on a line in the init file.  The name of the
-     key can be expressed in different ways, depending on which is most
-     comfortable for you.
-
-    KEYNAME: FUNCTION-NAME or MACRO
-          KEYNAME is the name of a key spelled out in English.  For
-          example:
-               Control-u: universal-argument
-               Meta-Rubout: backward-kill-word
-               Control-o: "> output"
-
-          In the above example, <C-u> is bound to the function
-          `universal-argument', and <C-o> is bound to run the macro
-          expressed on the right hand side (that is, to insert the text
-          `> output' into the line).
-
-    "KEYSEQ": FUNCTION-NAME or MACRO
-          KEYSEQ differs from KEYNAME above in that strings denoting an
-          entire key sequence can be specified, by placing the key
-          sequence in double quotes.  Some GNU Emacs style key escapes
-          can be used, as in the following example, but the special
-          character names are not recognized.
-
-               "\C-u": universal-argument
-               "\C-x\C-r": re-read-init-file
-               "\e[11~": "Function Key 1"
-
-          In the above example, <C-u> is bound to the function
-          `universal-argument' (just as it was in the first example),
-          `<C-x> <C-r>' is bound to the function `re-read-init-file',
-          and `<ESC> <[> <1> <1> <~>' is bound to insert the text
-          `Function Key 1'.
-
-     The following GNU Emacs style escape sequences are available when
-     specifying key sequences:
-
-    `\C-'
-          control prefix
-
-    `\M-'
-          meta prefix
-
-    `\e'
-          an escape character
-
-    `\\'
-          backslash
-
-    `\"'
-          <">, a double quotation mark
-
-    `\''
-          <'>, a single quote or apostrophe
-
-     In addition to the GNU Emacs style escape sequences, a second set
-     of backslash escapes is available:
-
-    `\a'
-          alert (bell)
-
-    `\b'
-          backspace
-
-    `\d'
-          delete
-
-    `\f'
-          form feed
-
-    `\n'
-          newline
-
-    `\r'
-          carriage return
-
-    `\t'
-          horizontal tab
-
-    `\v'
-          vertical tab
-
-    `\NNN'
-          the character whose `ASCII' code is the octal value NNN (one
-          to three digits)
-
-    `\xNNN'
-          the character whose `ASCII' code is the hexadecimal value NNN
-          (one to three digits)
-
-     When entering the text of a macro, single or double quotes must be
-     used to indicate a macro definition.  Unquoted text is assumed to
-     be a function name.  In the macro body, the backslash escapes
-     described above are expanded.  Backslash will quote any other
-     character in the macro text, including `"' and `''.  For example,
-     the following binding will make `C-x \' insert a single `\' into
-     the line:
-          "\C-x\\": "\\"

-
-Conditional Init Constructs
----------------------------
-
-   Readline implements a facility similar in spirit to the conditional
-compilation features of the C preprocessor which allows key bindings
-and variable settings to be performed as the result of tests.  There
-are four parser directives used.
-
-`$if'
-     The `$if' construct allows bindings to be made based on the
-     editing mode, the terminal being used, or the application using
-     Readline.  The text of the test extends to the end of the line; no
-     characters are required to isolate it.
-
-    `mode'
-          The `mode=' form of the `$if' directive is used to test
-          whether Readline is in `emacs' or `vi' mode.  This may be
-          used in conjunction with the `set keymap' command, for
-          instance, to set bindings in the `emacs-standard' and
-          `emacs-ctlx' keymaps only if Readline is starting out in
-          `emacs' mode.
-
-    `term'
-          The `term=' form may be used to include terminal-specific key
-          bindings, perhaps to bind the key sequences output by the
-          terminal's function keys.  The word on the right side of the
-          `=' is tested against both the full name of the terminal and
-          the portion of the terminal name before the first `-'.  This
-          allows `sun' to match both `sun' and `sun-cmd', for instance.
-
-    `application'
-          The APPLICATION construct is used to include
-          application-specific settings.  Each program using the
-          Readline library sets the APPLICATION NAME, and you can test
-          for it.  This could be used to bind key sequences to
-          functions useful for a specific program.  For instance, the
-          following command adds a key sequence that quotes the current
-          or previous word in Bash:
-               $if Bash
-               # Quote the current or previous word
-               "\C-xq": "\eb\"\ef\""
-               $endif
-
-`$endif'
-     This command, as seen in the previous example, terminates an `$if'
-     command.
-
-`$else'
-     Commands in this branch of the `$if' directive are executed if the
-     test fails.
-
-`$include'
-     This directive takes a single filename as an argument and reads
-     commands and bindings from that file.
-          $include /etc/inputrc

-
-Commands For Manipulating The History
--------------------------------------
-
-`accept-line (Newline, Return)'
-     Accept the line regardless of where the cursor is.  If this line is
-     non-empty, add it to the history list.  If this line was a history
-     line, then restore the history line to its original state.
-
-`previous-history (C-p)'
-     Move `up' through the history list.
-
-`next-history (C-n)'
-     Move `down' through the history list.
-
-`beginning-of-history (M-<)'
-     Move to the first line in the history.
-
-`end-of-history (M->)'
-     Move to the end of the input history, i.e., the line currently
-     being entered.
-
-`reverse-search-history (C-r)'
-     Search backward starting at the current line and moving `up'
-     through the history as necessary.  This is an incremental search.
-
-`forward-search-history (C-s)'
-     Search forward starting at the current line and moving `down'
-     through the the history as necessary.  This is an incremental
-     search.
-
-`non-incremental-reverse-search-history (M-p)'
-     Search backward starting at the current line and moving `up'
-     through the history as necessary using a non-incremental search
-     for a string supplied by the user.
-
-`non-incremental-forward-search-history (M-n)'
-     Search forward starting at the current line and moving `down'
-     through the the history as necessary using a non-incremental search
-     for a string supplied by the user.
-
-`history-search-forward ()'
-     Search forward through the history for the string of characters
-     between the start of the current line and the point.  This is a
-     non-incremental search.  By default, this command is unbound.
-
-`history-search-backward ()'
-     Search backward through the history for the string of characters
-     between the start of the current line and the point.  This is a
-     non-incremental search.  By default, this command is unbound.
-
-`yank-nth-arg (M-C-y)'
-     Insert the first argument to the previous command (usually the
-     second word on the previous line).  With an argument N, insert the
-     Nth word from the previous command (the words in the previous
-     command begin with word 0).  A negative argument inserts the Nth
-     word from the end of the previous command.
-
-`yank-last-arg (M-., M-_)'
-     Insert last argument to the previous command (the last word of the
-     previous history entry).  With an argument, behave exactly like
-     `yank-nth-arg'.  Successive calls to `yank-last-arg' move back
-     through the history list, inserting the last argument of each line
-     in turn.
-
-
-File: readline.info,  Node: Commands For Text,  Next: Commands For Killing,  Prev: Commands For History,  Up: Bindable Readline Commands
-
-Commands For Changing Text
---------------------------
-
-`delete-char (C-d)'
-     Delete the character under the cursor.  If the cursor is at the
-     beginning of the line, there are no characters in the line, and
-     the last character typed was not bound to `delete-char', then
-     return `EOF'.
-
-`backward-delete-char (Rubout)'
-     Delete the character behind the cursor.  A numeric argument means
-     to kill the characters instead of deleting them.
-
-`forward-backward-delete-char ()'
-     Delete the character under the cursor, unless the cursor is at the
-     end of the line, in which case the character behind the cursor is
-     deleted.  By default, this is not bound to a key.
-
-`quoted-insert (C-q, C-v)'
-     Add the next character typed to the line verbatim.  This is how to
-     insert key sequences like <C-q>, for example.
-
-`tab-insert (M-TAB)'
-     Insert a tab character.
-
-`self-insert (a, b, A, 1, !, ...)'
-     Insert yourself.
-
-`transpose-chars (C-t)'
-     Drag the character before the cursor forward over the character at
-     the cursor, moving the cursor forward as well.  If the insertion
-     point is at the end of the line, then this transposes the last two
-     characters of the line.  Negative arguments have no effect.
-
-`transpose-words (M-t)'
-     Drag the word before point past the word after point, moving point
-     past that word as well.
-
-`upcase-word (M-u)'
-     Uppercase the current (or following) word.  With a negative
-     argument, uppercase the previous word, but do not move the cursor.
-
-`downcase-word (M-l)'
-     Lowercase the current (or following) word.  With a negative
-     argument, lowercase the previous word, but do not move the cursor.
-
-`capitalize-word (M-c)'
-     Capitalize the current (or following) word.  With a negative
-     argument, capitalize the previous word, but do not move the cursor.
-

-
-Killing And Yanking
--------------------
-
-`kill-line (C-k)'
-     Kill the text from point to the end of the line.
-
-`backward-kill-line (C-x Rubout)'
-     Kill backward to the beginning of the line.
-
-`unix-line-discard (C-u)'
-     Kill backward from the cursor to the beginning of the current line.
-
-`kill-whole-line ()'
-     Kill all characters on the current line, no matter point is.  By
-     default, this is unbound.
-
-`kill-word (M-d)'
-     Kill from point to the end of the current word, or if between
-     words, to the end of the next word.  Word boundaries are the same
-     as `forward-word'.
-
-`backward-kill-word (M-DEL)'
-     Kill the word behind point.  Word boundaries are the same as
-     `backward-word'.
-
-`unix-word-rubout (C-w)'
-     Kill the word behind point, using white space as a word boundary.
-     The killed text is saved on the kill-ring.
-
-`delete-horizontal-space ()'
-     Delete all spaces and tabs around point.  By default, this is
-     unbound.
-
-`kill-region ()'
-     Kill the text in the current region.  By default, this command is
-     unbound.
-
-`copy-region-as-kill ()'
-     Copy the text in the region to the kill buffer, so it can be yanked
-     right away.  By default, this command is unbound.
-
-`copy-backward-word ()'
-     Copy the word before point to the kill buffer.  The word
-     boundaries are the same as `backward-word'.  By default, this
-     command is unbound.
-
-`copy-forward-word ()'
-     Copy the word following point to the kill buffer.  The word
-     boundaries are the same as `forward-word'.  By default, this
-     command is unbound.
-
-`yank (C-y)'
-     Yank the top of the kill ring into the buffer at the current
-     cursor position.
-
-`yank-pop (M-y)'
-     Rotate the kill-ring, and yank the new top.  You can only do this
-     if the prior command is yank or yank-pop.
-
-
-File: readline.info,  Node: Numeric Arguments,  Next: Commands For Completion,  Prev: Commands For Killing,  Up: Bindable Readline Commands
-
-Specifying Numeric Arguments
-----------------------------
-
-`digit-argument (M-0, M-1, ... M--)'
-     Add this digit to the argument already accumulating, or start a new
-     argument.  <M-> starts a negative argument.
-
-`universal-argument ()'
-     This is another way to specify an argument.  If this command is
-     followed by one or more digits, optionally with a leading minus
-     sign, those digits define the argument.  If the command is
-     followed by digits, executing `universal-argument' again ends the
-     numeric argument, but is otherwise ignored.  As a special case, if
-     this command is immediately followed by a character that is
-     neither a digit or minus sign, the argument count for the next
-     command is multiplied by four.  The argument count is initially
-     one, so executing this function the first time makes the argument
-     count four, a second time makes the argument count sixteen, and so
-     on.  By default, this is not bound to a key.
-
-
-File: readline.info,  Node: Commands For Completion,  Next: Keyboard Macros,  Prev: Numeric Arguments,  Up: Bindable Readline Commands
-
-Letting Readline Type For You
------------------------------
-
-`complete (TAB)'
-     Attempt to do completion on the text before the cursor.  This is
-     application-specific.  Generally, if you are typing a filename
-     argument, you can do filename completion; if you are typing a
-     command, you can do command completion; if you are typing in a
-     symbol to GDB, you can do symbol name completion; if you are
-     typing in a variable to Bash, you can do variable name completion,
-     and so on.
-
-`possible-completions (M-?)'
-     List the possible completions of the text before the cursor.
-
-`insert-completions (M-*)'
-     Insert all completions of the text before point that would have
-     been generated by `possible-completions'.
-
-`menu-complete ()'
-     Similar to `complete', but replaces the word to be completed with
-     a single match from the list of possible completions.  Repeated
-     execution of `menu-complete' steps through the list of possible
-     completions, inserting each match in turn.  At the end of the list
-     of completions, the bell is rung and the original text is restored.
-     An argument of N moves N positions forward in the list of matches;
-     a negative argument may be used to move backward through the list.
-     This command is intended to be bound to `TAB', but is unbound by
-     default.
-
-`delete-char-or-list ()'
-     Deletes the character under the cursor if not at the beginning or
-     end of the line (like `delete-char').  If at the end of the line,
-     behaves identically to `possible-completions'.  This command is
-     unbound by default.

-
-Keyboard Macros
----------------
-
-`start-kbd-macro (C-x ()'
-     Begin saving the characters typed into the current keyboard macro.
-
-`end-kbd-macro (C-x ))'
-     Stop saving the characters typed into the current keyboard macro
-     and save the definition.
-
-`call-last-kbd-macro (C-x e)'
-     Re-execute the last keyboard macro defined, by making the
-     characters in the macro appear as if typed at the keyboard.
-
-
-File: readline.info,  Node: Miscellaneous Commands,  Prev: Keyboard Macros,  Up: Bindable Readline Commands
-
-Some Miscellaneous Commands
----------------------------
-
-`re-read-init-file (C-x C-r)'
-     Read in the contents of the INPUTRC file, and incorporate any
-     bindings or variable assignments found there.
-
-`abort (C-g)'
-     Abort the current editing command and ring the terminal's bell
-     (subject to the setting of `bell-style').
-
-`do-uppercase-version (M-a, M-b, M-X, ...)'
-     If the metafied character X is lowercase, run the command that is
-     bound to the corresponding uppercase character.
-
-`prefix-meta (ESC)'
-     Make the next character typed be metafied.  This is for keyboards
-     without a meta key.  Typing `ESC f' is equivalent to typing `M-f'.
-
-`undo (C-_, C-x C-u)'
-     Incremental undo, separately remembered for each line.
-
-`revert-line (M-r)'
-     Undo all changes made to this line.  This is like executing the
-     `undo' command enough times to get back to the beginning.
-
-`tilde-expand (M-~)'
-     Perform tilde expansion on the current word.
-
-`set-mark (C-@)'
-     Set the mark to the current point.  If a numeric argument is
-     supplied, the mark is set to that position.
-
-`exchange-point-and-mark (C-x C-x)'
-     Swap the point with the mark.  The current cursor position is set
-     to the saved position, and the old cursor position is saved as the
-     mark.
-
-`character-search (C-])'
-     A character is read and point is moved to the next occurrence of
-     that character.  A negative count searches for previous
-     occurrences.
-
-`character-search-backward (M-C-])'
-     A character is read and point is moved to the previous occurrence
-     of that character.  A negative count searches for subsequent
-     occurrences.
-
-`insert-comment (M-#)'
-     The value of the `comment-begin' variable is inserted at the
-     beginning of the current line, and the line is accepted as if a
-     newline had been typed.
-
-`dump-functions ()'
-     Print all of the functions and their key bindings to the Readline
-     output stream.  If a numeric argument is supplied, the output is
-     formatted in such a way that it can be made part of an INPUTRC
-     file.  This command is unbound by default.
-
-`dump-variables ()'
-     Print all of the settable variables and their values to the
-     Readline output stream.  If a numeric argument is supplied, the
-     output is formatted in such a way that it can be made part of an
-     INPUTRC file.  This command is unbound by default.
-
-`dump-macros ()'
-     Print all of the Readline key sequences bound to macros and the
-     strings they ouput.  If a numeric argument is supplied, the output
-     is formatted in such a way that it can be made part of an INPUTRC
-     file.  This command is unbound by default.

-
-Readline vi Mode
-================
-
-   While the Readline library does not have a full set of `vi' editing
-functions, it does contain enough to allow simple editing of the line.
-The Readline `vi' mode behaves as specified in the POSIX 1003.2
-standard.
-
-   In order to switch interactively between `emacs' and `vi' editing
-modes, use the command M-C-j (toggle-editing-mode).  The Readline
-default is `emacs' mode.
-
-   When you enter a line in `vi' mode, you are already placed in
-`insertion' mode, as if you had typed an `i'.  Pressing <ESC> switches
-you into `command' mode, where you can edit the text of the line with
-the standard `vi' movement keys, move to previous history lines with
-`k' and subsequent lines with `j', and so forth.
-
-   This document describes the GNU Readline Library, a utility for
-aiding in the consitency of user interface across discrete programs
-that need to provide a command line interface.

-Basic Behavior
-==============
-
-   Many programs provide a command line interface, such as `mail',
-`ftp', and `sh'.  For such programs, the default behaviour of Readline
-is sufficient.  This section describes how to use Readline in the
-simplest way possible, perhaps to replace calls in your code to
-`gets()' or `fgets ()'.
-
-   The function `readline ()' prints a prompt and then reads and returns
-a single line of text from the user.  The line `readline' returns is
-allocated with `malloc ()'; you should `free ()' the line when you are
-done with it.  The declaration for `readline' in ANSI C is
-
-     `char *readline (char *PROMPT);'
-
-So, one might say
-     `char *line = readline ("Enter a line: ");'
-
-in order to read a line of text from the user.  The line returned has
-the final newline removed, so only the text remains.
-
-   If `readline' encounters an `EOF' while reading the line, and the
-line is empty at that point, then `(char *)NULL' is returned.
-Otherwise, the line is ended just as if a newline had been typed.
-
-   If you want the user to be able to get at the line later, (with
-<C-p> for example), you must call `add_history ()' to save the line
-away in a "history" list of such lines.
-
-     `add_history (line)';
-
-For full details on the GNU History Library, see the associated manual.
-
-   It is preferable to avoid saving empty lines on the history list,
-since users rarely have a burning need to reuse a blank line.  Here is
-a function which usefully replaces the standard `gets ()' library
-function, and has the advantage of no static buffer to overflow:
-
-     /* A static variable for holding the line. */
-     static char *line_read = (char *)NULL;
-     
-     /* Read a string, and return a pointer to it.  Returns NULL on EOF. */
-     char *
-     rl_gets ()
-     {
-       /* If the buffer has already been allocated, return the memory
-          to the free pool. */
-       if (line_read)
-         {
-           free (line_read);
-           line_read = (char *)NULL;
-         }
-     
-       /* Get a line from the user. */
-       line_read = readline ("");
-     
-       /* If the line has any text in it, save it on the history. */
-       if (line_read && *line_read)
-         add_history (line_read);
-     
-       return (line_read);
-     }
-
-   This function gives the user the default behaviour of <TAB>
-completion: completion on file names.  If you do not want Readline to
-complete on filenames, you can change the binding of the <TAB> key with
-`rl_bind_key ()'.
-
-     `int rl_bind_key (int KEY, int (*FUNCTION)());'
-
-   `rl_bind_key ()' takes two arguments: KEY is the character that you
-want to bind, and FUNCTION is the address of the function to call when
-KEY is pressed.  Binding <TAB> to `rl_insert ()' makes <TAB> insert
-itself.  `rl_bind_key ()' returns non-zero if KEY is not a valid ASCII
-character code (between 0 and 255).
-
-   Thus, to disable the default <TAB> behavior, the following suffices:
-     `rl_bind_key ('\t', rl_insert);'
-
-   This code should be executed once at the start of your program; you
-might write a function called `initialize_readline ()' which performs
-this and other desired initializations, such as installing custom
-completers (*note Custom Completers::.).

-Custom Functions
-================
-
-   Readline provides many functions for manipulating the text of the
-line, but it isn't possible to anticipate the needs of all programs.
-This section describes the various functions and variables defined
-within the Readline library which allow a user program to add
-customized functionality to Readline.
-
-   Before declaring any functions that customize Readline's behavior, or
-using any functionality Readline provides in other code, an application
-writer should include the file `<readline/readline.h>' in any file that
-uses Readline's features.  Since some of the definitions in
-`readline.h' use the `stdio' library, the file `<stdio.h>' should be
-included before `readline.h'.

-
-The Function Type
------------------
-
-   For readabilty, we declare a new type of object, called "Function".
-A `Function' is a C function which returns an `int'.  The type
-declaration for `Function' is:
-
-`typedef int Function ();'
-
-   The reason for declaring this new type is to make it easier to write
-code describing pointers to C functions.  Let us say we had a variable
-called FUNC which was a pointer to a function.  Instead of the classic
-C declaration
-
-   `int (*)()func;'
-
-we may write
-
-   `Function *func;'
-
-Similarly, there are
-
-     typedef void VFunction ();
-     typedef char *CPFunction (); and
-     typedef char **CPPFunction ();
-
-for functions returning no value, `pointer to char', and `pointer to
-pointer to char', respectively.
-
-
-File: readline.info,  Node: Function Writing,  Prev: The Function Type,  Up: Custom Functions
-
-Writing a New Function
-----------------------
-
-   In order to write new functions for Readline, you need to know the
-calling conventions for keyboard-invoked functions, and the names of the
-variables that describe the current state of the line read so far.
-
-   The calling sequence for a command `foo' looks like
-
-     `foo (int count, int key)'
-
-where COUNT is the numeric argument (or 1 if defaulted) and KEY is the
-key that invoked this function.
-
-   It is completely up to the function as to what should be done with
-the numeric argument.  Some functions use it as a repeat count, some as
-a flag, and others to choose alternate behavior (refreshing the current
-line as opposed to refreshing the screen, for example).  Some choose to
-ignore it.  In general, if a function uses the numeric argument as a
-repeat count, it should be able to do something useful with both
-negative and positive arguments.  At the very least, it should be aware
-that it can be passed a negative argument.
-

-
-Readline Variables
-==================
-
-   These variables are available to function writers.
-
- - Variable: char * rl_line_buffer
-     This is the line gathered so far.  You are welcome to modify the
-     contents of the line, but see *Note Allowing Undoing::.  The
-     function `rl_extend_line_buffer' is available to increase the
-     memory allocated to `rl_line_buffer'.
-
- - Variable: int rl_point
-     The offset of the current cursor position in `rl_line_buffer' (the
-     *point*).
-
- - Variable: int rl_end
-     The number of characters present in `rl_line_buffer'.  When
-     `rl_point' is at the end of the line, `rl_point' and `rl_end' are
-     equal.
-
- - Variable: int rl_mark
-     The mark (saved position) in the current line.  If set, the mark
-     and point define a *region*.
-
- - Variable: int rl_done
-     Setting this to a non-zero value causes Readline to return the
-     current line immediately.
-
- - Variable: int rl_pending_input
-     Setting this to a value makes it the next keystroke read.  This is
-     a way to stuff a single character into the input stream.
-
- - Variable: int rl_erase_empty_line
-     Setting this to a non-zero value causes Readline to completely
-     erase the current line, including any prompt, any time a newline
-     is typed as the only character on an otherwise-empty line.  The
-     cursor is moved to the beginning of the newly-blank line.
-
- - Variable: char * rl_prompt
-     The prompt Readline uses.  This is set from the argument to
-     `readline ()', and should not be assigned to directly.
-
- - Variable: int rl_already_prompted
-     If an application wishes to display the prompt itself, rather than
-     have Readline do it the first time `readline()' is called, it
-     should set this variable to a non-zero value after displaying the
-     prompt.  The prompt must also be passed as the argument to
-     `readline()' so the redisplay functions can update the display
-     properly.  The calling application is responsible for managing the
-     value; Readline never sets it.
-
- - Variable: char * rl_library_version
-     The version number of this revision of the library.
-
- - Variable: char * rl_terminal_name
-     The terminal type, used for initialization.
-
- - Variable: char * rl_readline_name
-     This variable is set to a unique name by each application using
-     Readline.  The value allows conditional parsing of the inputrc file
-     (*note Conditional Init Constructs::.).
-
- - Variable: FILE * rl_instream
-     The stdio stream from which Readline reads input.
-
- - Variable: FILE * rl_outstream
-     The stdio stream to which Readline performs output.
-
- - Variable: Function * rl_startup_hook
-     If non-zero, this is the address of a function to call just before
-     `readline' prints the first prompt.
-
- - Variable: Function * rl_pre_input_hook
-     If non-zero, this is the address of a function to call after the
-     first prompt has been printed and just before `readline' starts
-     reading input characters.
-
- - Variable: Function * rl_event_hook
-     If non-zero, this is the address of a function to call periodically
-     when readline is waiting for terminal input.
-
- - Variable: Function * rl_getc_function
-     If non-zero, `readline' will call indirectly through this pointer
-     to get a character from the input stream.  By default, it is set to
-     `rl_getc', the default `readline' character input function (*note
-     Utility Functions::.).
-
- - Variable: VFunction * rl_redisplay_function
-     If non-zero, `readline' will call indirectly through this pointer
-     to update the display with the current contents of the editing
-     buffer.  By default, it is set to `rl_redisplay', the default
-     `readline' redisplay function (*note Redisplay::.).
-
- - Variable: Keymap rl_executing_keymap
-     This variable is set to the keymap (*note Keymaps::.) in which the
-     currently executing readline function was found.
-
- - Variable: Keymap rl_binding_keymap
-     This variable is set to the keymap (*note Keymaps::.) in which the
-     last key binding occurred.

-
-File: readline.info,  Node: Function Naming,  Next: Keymaps,  Up: Readline Convenience Functions
-
-Naming a Function
------------------
-
-   The user can dynamically change the bindings of keys while using
-Readline.  This is done by representing the function with a descriptive
-name.  The user is able to type the descriptive name when referring to
-the function.  Thus, in an init file, one might find
-
-     Meta-Rubout:	backward-kill-word
-
-   This binds the keystroke <Meta-Rubout> to the function
-*descriptively* named `backward-kill-word'.  You, as the programmer,
-should bind the functions you write to descriptive names as well.
-Readline provides a function for doing that:
-
- - Function: int rl_add_defun (char *name, Function *function, int key)
-     Add NAME to the list of named functions.  Make FUNCTION be the
-     function that gets called.  If KEY is not -1, then bind it to
-     FUNCTION using `rl_bind_key ()'.
-
-   Using this function alone is sufficient for most applications.  It is
-the recommended way to add a few functions to the default functions that
-Readline has built in.  If you need to do something other than adding a
-function to Readline, you may need to use the underlying functions
-described below.
-
-
-File: readline.info,  Node: Keymaps,  Next: Binding Keys,  Prev: Function Naming,  Up: Readline Convenience Functions
-
-Selecting a Keymap
-------------------
-
-   Key bindings take place on a "keymap".  The keymap is the
-association between the keys that the user types and the functions that
-get run.  You can make your own keymaps, copy existing keymaps, and tell
-Readline which keymap to use.
-
- - Function: Keymap rl_make_bare_keymap ()
-     Returns a new, empty keymap.  The space for the keymap is
-     allocated with `malloc ()'; you should `free ()' it when you are
-     done.
-
- - Function: Keymap rl_copy_keymap (Keymap map)
-     Return a new keymap which is a copy of MAP.
-
- - Function: Keymap rl_make_keymap ()
-     Return a new keymap with the printing characters bound to
-     rl_insert, the lowercase Meta characters bound to run their
-     equivalents, and the Meta digits bound to produce numeric
-     arguments.
-
- - Function: void rl_discard_keymap (Keymap keymap)
-     Free the storage associated with KEYMAP.
-
-   Readline has several internal keymaps.  These functions allow you to
-change which keymap is active.
-
- - Function: Keymap rl_get_keymap ()
-     Returns the currently active keymap.
-
- - Function: void rl_set_keymap (Keymap keymap)
-     Makes KEYMAP the currently active keymap.
-
- - Function: Keymap rl_get_keymap_by_name (char *name)
-     Return the keymap matching NAME.  NAME is one which would be
-     supplied in a `set keymap' inputrc line (*note Readline Init
-     File::.).
-
- - Function: char * rl_get_keymap_name (Keymap keymap)
-     Return the name matching KEYMAP.  NAME is one which would be
-     supplied in a `set keymap' inputrc line (*note Readline Init
-     File::.).
-
-
-File: readline.info,  Node: Binding Keys,  Next: Associating Function Names and Bindings,  Prev: Keymaps,  Up: Readline Convenience Functions
-
-Binding Keys
-------------
-
-   You associate keys with functions through the keymap.  Readline has
-several internal keymaps: `emacs_standard_keymap', `emacs_meta_keymap',
-`emacs_ctlx_keymap', `vi_movement_keymap', and `vi_insertion_keymap'.
-`emacs_standard_keymap' is the default, and the examples in this manual
-assume that.
-
-   Since `readline' installs a set of default key bindings the first
-time it is called, there is always the danger that a custom binding
-installed before the first call to `readline' will be overridden.  An
-alternate mechanism is to install custom key bindings in an
-initialization function assigned to the `rl_startup_hook' variable
-(*note Readline Variables::.).
-
-   These functions manage key bindings.
-
- - Function: int rl_bind_key (int key, Function *function)
-     Binds KEY to FUNCTION in the currently active keymap.  Returns
-     non-zero in the case of an invalid KEY.
-
- - Function: int rl_bind_key_in_map (int key, Function *function,
-          Keymap map)
-     Bind KEY to FUNCTION in MAP.  Returns non-zero in the case of an
-     invalid KEY.
-
- - Function: int rl_unbind_key (int key)
-     Bind KEY to the null function in the currently active keymap.
-     Returns non-zero in case of error.
-
- - Function: int rl_unbind_key_in_map (int key, Keymap map)
-     Bind KEY to the null function in MAP.  Returns non-zero in case of
-     error.
-
- - Function: int rl_unbind_function_in_map (Function *function, Keymap
-          map)
-     Unbind all keys that execute FUNCTION in MAP.
-
- - Function: int rl_unbind_command_in_map (char *command, Keymap map)
-     Unbind all keys that are bound to COMMAND in MAP.
-
- - Function: int rl_generic_bind (int type, char *keyseq, char *data,
-          Keymap map)
-     Bind the key sequence represented by the string KEYSEQ to the
-     arbitrary pointer DATA.  TYPE says what kind of data is pointed to
-     by DATA; this can be a function (`ISFUNC'), a macro (`ISMACR'), or
-     a keymap (`ISKMAP').  This makes new keymaps as necessary.  The
-     initial keymap in which to do bindings is MAP.
-
- - Function: int rl_parse_and_bind (char *line)
-     Parse LINE as if it had been read from the `inputrc' file and
-     perform any key bindings and variable assignments found (*note
-     Readline Init File::.).
-
- - Function: int rl_read_init_file (char *filename)
-     Read keybindings and variable assignments from FILENAME (*note
-     Readline Init File::.).
-
-
-File: readline.info,  Node: Associating Function Names and Bindings,  Next: Allowing Undoing,  Prev: Binding Keys,  Up: Readline Convenience Functions
-
-Associating Function Names and Bindings
----------------------------------------
-
-   These functions allow you to find out what keys invoke named
-functions and the functions invoked by a particular key sequence.
-
- - Function: Function * rl_named_function (char *name)
-     Return the function with name NAME.
-
- - Function: Function * rl_function_of_keyseq (char *keyseq, Keymap
-          map, int *type)
-     Return the function invoked by KEYSEQ in keymap MAP.  If MAP is
-     NULL, the current keymap is used.  If TYPE is not NULL, the type
-     of the object is returned in it (one of `ISFUNC', `ISKMAP', or
-     `ISMACR').
-
- - Function: char ** rl_invoking_keyseqs (Function *function)
-     Return an array of strings representing the key sequences used to
-     invoke FUNCTION in the current keymap.
-
- - Function: char ** rl_invoking_keyseqs_in_map (Function *function,
-          Keymap map)
-     Return an array of strings representing the key sequences used to
-     invoke FUNCTION in the keymap MAP.
-
- - Function: void rl_function_dumper (int readable)
-     Print the readline function names and the key sequences currently
-     bound to them to `rl_outstream'.  If READABLE is non-zero, the
-     list is formatted in such a way that it can be made part of an
-     `inputrc' file and re-read.
-
- - Function: void rl_list_funmap_names ()
-     Print the names of all bindable Readline functions to
-     `rl_outstream'.
-
- - Function: char ** rl_funmap_names ()
-     Return a NULL terminated array of known function names.  The array
-     is sorted.  The array itself is allocated, but not the strings
-     inside.  You should free () the array when you done, but not the
-     pointrs.

-
-Allowing Undoing
-----------------
-
-   Supporting the undo command is a painless thing, and makes your
-functions much more useful.  It is certainly easy to try something if
-you know you can undo it.  I could use an undo function for the stock
-market.
-
-   If your function simply inserts text once, or deletes text once, and
-uses `rl_insert_text ()' or `rl_delete_text ()' to do it, then undoing
-is already done for you automatically.
-
-   If you do multiple insertions or multiple deletions, or any
-combination of these operations, you should group them together into
-one operation.  This is done with `rl_begin_undo_group ()' and
-`rl_end_undo_group ()'.
-
-   The types of events that can be undone are:
-
-     enum undo_code { UNDO_DELETE, UNDO_INSERT, UNDO_BEGIN, UNDO_END };
-
-   Notice that `UNDO_DELETE' means to insert some text, and
-`UNDO_INSERT' means to delete some text.  That is, the undo code tells
-undo what to undo, not how to undo it.  `UNDO_BEGIN' and `UNDO_END' are
-tags added by `rl_begin_undo_group ()' and `rl_end_undo_group ()'.
-
- - Function: int rl_begin_undo_group ()
-     Begins saving undo information in a group construct.  The undo
-     information usually comes from calls to `rl_insert_text ()' and
-     `rl_delete_text ()', but could be the result of calls to
-     `rl_add_undo ()'.
-
- - Function: int rl_end_undo_group ()
-     Closes the current undo group started with `rl_begin_undo_group
-     ()'.  There should be one call to `rl_end_undo_group ()' for each
-     call to `rl_begin_undo_group ()'.
-
- - Function: void rl_add_undo (enum undo_code what, int start, int end,
-          char *text)
-     Remember how to undo an event (according to WHAT).  The affected
-     text runs from START to END, and encompasses TEXT.
-
- - Function: void free_undo_list ()
-     Free the existing undo list.
-
- - Function: int rl_do_undo ()
-     Undo the first thing on the undo list.  Returns `0' if there was
-     nothing to undo, non-zero if something was undone.
-
-   Finally, if you neither insert nor delete text, but directly modify
-the existing text (e.g., change its case), call `rl_modifying ()' once,
-just before you modify the text.  You must supply the indices of the
-text range that you are going to modify.
-
- - Function: int rl_modifying (int start, int end)
-     Tell Readline to save the text between START and END as a single
-     undo unit.  It is assumed that you will subsequently modify that
-     text.

-Redisplay
----------
-
- - Function: void rl_redisplay ()
-     Change what's displayed on the screen to reflect the current
-     contents of `rl_line_buffer'.
-
- - Function: int rl_forced_update_display ()
-     Force the line to be updated and redisplayed, whether or not
-     Readline thinks the screen display is correct.
-
- - Function: int rl_on_new_line ()
-     Tell the update functions that we have moved onto a new (empty)
-     line, usually after ouputting a newline.
-
- - Function: int rl_on_new_line_with_prompt ()
-     Tell the update functions that we have moved onto a new line, with
-     RL_PROMPT already displayed.  This could be used by applications
-     that want to output the prompt string themselves, but still need
-     Readline to know the prompt string length for redisplay.  It
-     should be used after setting RL_ALREADY_PROMPTED.
-
- - Function: int rl_reset_line_state ()
-     Reset the display state to a clean state and redisplay the current
-     line starting on a new line.
-
- - Function: int rl_message (va_alist)
-     The arguments are a string as would be supplied to `printf'.  The
-     resulting string is displayed in the "echo area".  The echo area
-     is also used to display numeric arguments and search strings.
-
- - Function: int rl_clear_message ()
-     Clear the message in the echo area.
-
- - Function: void rl_save_prompt ()
-     Save the local Readline prompt display state in preparation for
-     displaying a new message in the message area with `rl_message'.
-
- - Function: void rl_restore_prompt ()
-     Restore the local Readline prompt display state saved by the most
-     recent call to `rl_save_prompt'.

---------------
-
- - Function: int rl_insert_text (char *text)
-     Insert TEXT into the line at the current cursor position.
-
- - Function: int rl_delete_text (int start, int end)
-     Delete the text between START and END in the current line.
-
- - Function: char * rl_copy_text (int start, int end)
-     Return a copy of the text between START and END in the current
-     line.
-
- - Function: int rl_kill_text (int start, int end)
-     Copy the text between START and END in the current line to the
-     kill ring, appending or prepending to the last kill if the last
-     command was a kill command.  The text is deleted.  If START is
-     less than END, the text is appended, otherwise prepended.  If the
-     last command was not a kill, a new kill ring slot is used.

-Utility Functions
------------------
-
- - Function: int rl_read_key ()
-     Return the next character available.  This handles input inserted
-     into the input stream via PENDING INPUT (*note Readline
-     Variables::.)  and `rl_stuff_char ()', macros, and characters read
-     from the keyboard.
-
- - Function: int rl_getc (FILE *)
-     Return the next character available from the keyboard.
-
- - Function: int rl_stuff_char (int c)
-     Insert C into the Readline input stream.  It will be "read" before
-     Readline attempts to read characters from the terminal with
-     `rl_read_key ()'.
-
- - Function: int rl_extend_line_buffer (int len)
-     Ensure that `rl_line_buffer' has enough space to hold LEN
-     characters, possibly reallocating it if necessary.
-
- - Function: int rl_initialize ()
-     Initialize or re-initialize Readline's internal state.
-
- - Function: int rl_reset_terminal (char *terminal_name)
-     Reinitialize Readline's idea of the terminal settings using
-     TERMINAL_NAME as the terminal type (e.g., `vt100').  If
-     TERMINAL_NAME is NULL, the value of the `TERM' environment
-     variable is used.
-
- - Function: int alphabetic (int c)
-     Return 1 if C is an alphabetic character.
-
- - Function: int numeric (int c)
-     Return 1 if C is a numeric character.

-     Ring the terminal bell, obeying the setting of `bell-style'.
-
- - Function: void rl_display_match_list (char **matches, int len, int
-          max)
-     A convenience function for displaying a list of strings in
-     columnar format on Readline's output stream.  `matches' is the list
-     of strings, in argv format, such as a list of completion matches.
-     `len' is the number of strings in `matches', and `max' is the
-     length of the longest string in `matches'.  This function uses the
-     setting of `print-completions-horizontally' to select how the
-     matches are displayed (*note Readline Init File Syntax::.).

-
-Alternate Interface
--------------------
-
-   An alternate interface is available to plain `readline()'.  Some
-applications need to interleave keyboard I/O with file, device, or
-window system I/O, typically by using a main loop to `select()' on
-various file descriptors.  To accomodate this need, readline can also
-be invoked as a `callback' function from an event loop.  There are
-functions available to make this easy.
-
- - Function: void rl_callback_handler_install (char *prompt, Vfunction
-          *lhandler)
-     Set up the terminal for readline I/O and display the initial
-     expanded value of PROMPT.  Save the value of LHANDLER to use as a
-     callback when a complete line of input has been entered.
-
- - Function: void rl_callback_read_char ()
-     Whenever an application determines that keyboard input is
-     available, it should call `rl_callback_read_char()', which will
-     read the next character from the current input source.  If that
-     character completes the line, `rl_callback_read_char' will invoke
-     the LHANDLER function saved by `rl_callback_handler_install' to
-     process the line.  `EOF' is  indicated by calling LHANDLER with a
-     `NULL' line.
-
- - Function: void rl_callback_handler_remove ()
-     Restore the terminal to its initial state and remove the line
-     handler.  This may be called from within a callback as well as
-     independently.
-
-An Example
-----------
-
-   Here is a function which changes lowercase characters to their
-uppercase equivalents, and uppercase characters to lowercase.  If this
-function was bound to `M-c', then typing `M-c' would change the case of
-the character under point.  Typing `M-1 0 M-c' would change the case of
-the following 10 characters, leaving the cursor on the last character
-changed.
-
-     /* Invert the case of the COUNT following characters. */
-     int
-     invert_case_line (count, key)
-          int count, key;
-     {
-       register int start, end, i;
-     
-       start = rl_point;

-       /* Find the end of the range to modify. */
-       end = start + (count * direction);
-     
-       /* Force it to be within range. */
-       if (end > rl_end)

-       if (start == end)
-         return (0);
-     
-       if (start > end)
-         {
-           int temp = start;
-           start = end;
-           end = temp;
-         }
-     
-       /* Tell readline that we are modifying the line, so it will save
-          the undo information. */
-       rl_modifying (start, end);
-     
-       for (i = start; i != end; i++)
-         {
-           if (uppercase_p (rl_line_buffer[i]))
-             rl_line_buffer[i] = to_lower (rl_line_buffer[i]);
-           else if (lowercase_p (rl_line_buffer[i]))
-             rl_line_buffer[i] = to_upper (rl_line_buffer[i]);
-         }
-       /* Move point to on top of the last character changed. */
-       rl_point = (direction == 1) ? end - 1 : start;
-       return (0);
-     }

-Readline Signal Handling
-========================
-
-   Signals are asynchronous events sent to a process by the Unix kernel,
-sometimes on behalf of another process.  They are intended to indicate
-exceptional events, like a user pressing the interrupt key on his
-terminal, or a network connection being broken.  There is a class of
-signals that can be sent to the process currently reading input from
-the keyboard.  Since Readline changes the terminal attributes when it
-is called, it needs to perform special processing when a signal is
-received to restore the terminal to a sane state, or provide application
-writers with functions to do so manually.
-
-   Readline contains an internal signal handler that is installed for a
-number of signals (`SIGINT', `SIGQUIT', `SIGTERM', `SIGALRM',
-`SIGTSTP', `SIGTTIN', and `SIGTTOU').  When one of these signals is
-received, the signal handler will reset the terminal attributes to
-those that were in effect before `readline ()' was called, reset the
-signal handling to what it was before `readline ()' was called, and
-resend the signal to the calling application.  If and when the calling
-application's signal handler returns, Readline will reinitialize the
-terminal and continue to accept input.  When a `SIGINT' is received,
-the Readline signal handler performs some additional work, which will
-cause any partially-entered line to be aborted (see the description of
-`rl_free_line_state ()').
-
-   There is an additional Readline signal handler, for `SIGWINCH', which
-the kernel sends to a process whenever the terminal's size changes (for
-example, if a user resizes an `xterm').  The Readline `SIGWINCH'
-handler updates Readline's internal screen size state, and then calls
-any `SIGWINCH' signal handler the calling application has installed.
-Readline calls the application's `SIGWINCH' signal handler without
-resetting the terminal to its original state.  If the application's
-signal handler does more than update its idea of the terminal size and
-return (for example, a `longjmp' back to a main processing loop), it
-*must* call `rl_cleanup_after_signal ()' (described below), to restore
-the terminal state.
-
-   Readline provides two variables that allow application writers to
-control whether or not it will catch certain signals and act on them
-when they are received.  It is important that applications change the
-values of these variables only when calling `readline ()', not in a
-signal handler, so Readline's internal signal state is not corrupted.
-
- - Variable: int rl_catch_signals
-     If this variable is non-zero, Readline will install signal
-     handlers for `SIGINT', `SIGQUIT', `SIGTERM', `SIGALRM', `SIGTSTP',
-     `SIGTTIN', and `SIGTTOU'.
-
-     The default value of `rl_catch_signals' is 1.
-
- - Variable: int rl_catch_sigwinch
-     If this variable is non-zero, Readline will install a signal
-     handler for `SIGWINCH'.
-
-     The default value of `rl_catch_sigwinch' is 1.
-
-   If an application does not wish to have Readline catch any signals,
-or to handle signals other than those Readline catches (`SIGHUP', for
-example), Readline provides convenience functions to do the necessary
-terminal and internal state cleanup upon receipt of a signal.
-
- - Function: void rl_cleanup_after_signal (void)
-     This function will reset the state of the terminal to what it was
-     before `readline ()' was called, and remove the Readline signal
-     handlers for all signals, depending on the values of
-     `rl_catch_signals' and `rl_catch_sigwinch'.
-
- - Function: void rl_free_line_state (void)
-     This will free any partial state associated with the current input
-     line (undo information, any partial history entry, any
-     partially-entered keyboard macro, and any partially-entered
-     numeric argument).  This should be called before
-     `rl_cleanup_after_signal ()'.  The Readline signal handler for
-     `SIGINT' calls this to abort the current input line.
-
- - Function: void rl_reset_after_signal (void)
-     This will reinitialize the terminal and reinstall any Readline
-     signal handlers, depending on the values of `rl_catch_signals' and
-     `rl_catch_sigwinch'.
-
-   If an application does not wish Readline to catch `SIGWINCH', it may
-call `rl_resize_terminal ()' to force Readline to update its idea of
-the terminal size when a `SIGWINCH' is received.
-
- - Function: void rl_resize_terminal (void)
-     Update Readline's internal screen size.
-
-   The following functions install and remove Readline's signal
-handlers.
-
- - Function: int rl_set_signals (void)
-     Install Readline's signal handler for `SIGINT', `SIGQUIT',
-     `SIGTERM', `SIGALRM', `SIGTSTP', `SIGTTIN', `SIGTTOU', and
-     `SIGWINCH', depending on the values of `rl_catch_signals' and
-     `rl_catch_sigwinch'.
-
- - Function: int rl_clear_signals (void)
-     Remove all of the Readline signal handlers installed by
-     `rl_set_signals ()'.

-Custom Completers
-=================
-
-   Typically, a program that reads commands from the user has a way of
-disambiguating commands and data.  If your program is one of these, then
-it can provide completion for commands, data, or both.  The following
-sections describe how your program and Readline cooperate to provide
-this service.
-

-
-* How Completing Works::	The logic used to do completion.
-* Completion Functions::	Functions provided by Readline.

-
-How Completing Works
---------------------
-
-   In order to complete some text, the full list of possible completions
-must be available.  That is, it is not possible to accurately expand a
-partial word without knowing all of the possible words which make sense
-in that context.  The Readline library provides the user interface to
-completion, and two of the most common completion functions:  filename
-and username.  For completing other types of text, you must write your
-own completion function.  This section describes exactly what such
-functions must do, and provides an example.
-
-   There are three major functions used to perform completion:
-
-  1. The user-interface function `rl_complete ()'.  This function is
-     called with the same arguments as other Readline functions
-     intended for interactive use:  COUNT and INVOKING_KEY.  It
-     isolates the word to be completed and calls `completion_matches
-     ()' to generate a list of possible completions.  It then either
-     lists the possible completions, inserts the possible completions,
-     or actually performs the completion, depending on which behavior
-     is desired.
-
-  2. The internal function `completion_matches ()' uses your
-     "generator" function to generate the list of possible matches, and
-     then returns the array of these matches.  You should place the
-     address of your generator function in
-     `rl_completion_entry_function'.
-
-  3. The generator function is called repeatedly from
-     `completion_matches ()', returning a string each time.  The
-     arguments to the generator function are TEXT and STATE.  TEXT is
-     the partial word to be completed.  STATE is zero the first time
-     the function is called, allowing the generator to perform any
-     necessary initialization, and a positive non-zero integer for each
-     subsequent call.  When the generator function returns `(char
-     *)NULL' this signals `completion_matches ()' that there are no
-     more possibilities left.  Usually the generator function computes
-     the list of possible completions when STATE is zero, and returns
-     them one at a time on subsequent calls.  Each string the generator
-     function returns as a match must be allocated with `malloc()';
-     Readline frees the strings when it has finished with them.
-
-
- - Function: int rl_complete (int ignore, int invoking_key)
-     Complete the word at or before point.  You have supplied the
-     function that does the initial simple matching selection algorithm
-     (see `completion_matches ()').  The default is to do filename
-     completion.
-
- - Variable: Function * rl_completion_entry_function
-     This is a pointer to the generator function for `completion_matches
-     ()'.  If the value of `rl_completion_entry_function' is `(Function
-     *)NULL' then the default filename generator function,
-     `filename_completion_function ()', is used.

-
-Completion Functions
---------------------
-
-   Here is the complete list of callable completion functions present in
-Readline.
-
- - Function: int rl_complete_internal (int what_to_do)
-     Complete the word at or before point.  WHAT_TO_DO says what to do
-     with the completion.  A value of `?' means list the possible
-     completions.  `TAB' means do standard completion.  `*' means
-     insert all of the possible completions.  `!' means to display all
-     of the possible completions, if there is more than one, as well as
-     performing partial completion.
-
- - Function: int rl_complete (int ignore, int invoking_key)
-     Complete the word at or before point.  You have supplied the
-     function that does the initial simple matching selection algorithm
-     (see `completion_matches ()' and `rl_completion_entry_function').
-     The default is to do filename completion.  This calls
-     `rl_complete_internal ()' with an argument depending on
-     INVOKING_KEY.
-
- - Function: int rl_possible_completions (int count, int invoking_key))
-     List the possible completions.  See description of `rl_complete
-     ()'.  This calls `rl_complete_internal ()' with an argument of `?'.
-
- - Function: int rl_insert_completions (int count, int invoking_key))
-     Insert the list of possible completions into the line, deleting the
-     partially-completed word.  See description of `rl_complete ()'.
-     This calls `rl_complete_internal ()' with an argument of `*'.
-
- - Function: char ** completion_matches (char *text, CPFunction
-          *entry_func)
-     Returns an array of `(char *)' which is a list of completions for
-     TEXT.  If there are no completions, returns `(char **)NULL'.  The
-     first entry in the returned array is the substitution for TEXT.
-     The remaining entries are the possible completions.  The array is
-     terminated with a `NULL' pointer.
-
-     ENTRY_FUNC is a function of two args, and returns a `(char *)'.
-     The first argument is TEXT.  The second is a state argument; it is
-     zero on the first call, and non-zero on subsequent calls.
-     ENTRY_FUNC returns a `NULL'  pointer to the caller when there are
-     no more matches.
-
- - Function: char * filename_completion_function (char *text, int state)
-     A generator function for filename completion in the general case.
-     Note that completion in Bash is a little different because of all
-     the pathnames that must be followed when looking up completions
-     for a command.  The Bash source is a useful reference for writing
-     custom completion functions.
-
- - Function: char * username_completion_function (char *text, int state)
-     A completion generator for usernames.  TEXT contains a partial
-     username preceded by a random character (usually `~').  As with all
-     completion generators, STATE is zero on the first call and non-zero
-     for subsequent calls.

-
-Completion Variables
---------------------
-
- - Variable: Function * rl_completion_entry_function
-     A pointer to the generator function for `completion_matches ()'.
-     `NULL' means to use `filename_completion_function ()', the default
-     filename completer.
-
- - Variable: CPPFunction * rl_attempted_completion_function
-     A pointer to an alternative function to create matches.  The
-     function is called with TEXT, START, and END.  START and END are
-     indices in `rl_line_buffer' saying what the boundaries of TEXT
-     are.  If this function exists and returns `NULL', or if this
-     variable is set to `NULL', then `rl_complete ()' will call the
-     value of `rl_completion_entry_function' to generate matches,
-     otherwise the array of strings returned will be used.
-
- - Variable: CPFunction * rl_filename_quoting_function
-     A pointer to a function that will quote a filename in an
-     application- specific fashion.  This is called if filename
-     completion is being attempted and one of the characters in
-     `rl_filename_quote_characters' appears in a completed filename.
-     The function is called with TEXT, MATCH_TYPE, and QUOTE_POINTER.
-     The TEXT is the filename to be quoted.  The MATCH_TYPE is either
-     `SINGLE_MATCH', if there is only one completion match, or
-     `MULT_MATCH'.  Some functions use this to decide whether or not to
-     insert a closing quote character.  The QUOTE_POINTER is a pointer
-     to any opening quote character the user typed.  Some functions
-     choose to reset this character.
-
- - Variable: CPFunction * rl_filename_dequoting_function
-     A pointer to a function that will remove application-specific
-     quoting characters from a filename before completion is attempted,
-     so those characters do not interfere with matching the text
-     against names in the filesystem.  It is called with TEXT, the text
-     of the word to be dequoted, and QUOTE_CHAR, which is the quoting
-     character that delimits the filename (usually `'' or `"').  If
-     QUOTE_CHAR is zero, the filename was not in an embedded string.
-
- - Variable: Function * rl_char_is_quoted_p
-     A pointer to a function to call that determines whether or not a
-     specific character in the line buffer is quoted, according to
-     whatever quoting mechanism the program calling readline uses.  The
-     function is called with two arguments: TEXT, the text of the line,
-     and INDEX, the index of the character in the line.  It is used to
-     decide whether a character found in
-     `rl_completer_word_break_characters' should be used to break words
-     for the completer.
-
- - Variable: int rl_completion_query_items
-     Up to this many items will be displayed in response to a
-     possible-completions call.  After that, we ask the user if she is
-     sure she wants to see them all.  The default value is 100.
-
- - Variable: char * rl_basic_word_break_characters
-     The basic list of characters that signal a break between words for
-     the completer routine.  The default value of this variable is the
-     characters which break words for completion in Bash, i.e., `"
-     \t\n\"\\'`@$><=;|&{("'.
-
- - Variable: char * rl_basic_quote_characters
-     List of quote characters which can cause a word break.
-
- - Variable: char * rl_completer_word_break_characters
-     The list of characters that signal a break between words for
-     `rl_complete_internal ()'.  The default list is the value of
-     `rl_basic_word_break_characters'.
-
- - Variable: char * rl_completer_quote_characters
-     List of characters which can be used to quote a substring of the
-     line.  Completion occurs on the entire substring, and within the
-     substring `rl_completer_word_break_characters' are treated as any
-     other character, unless they also appear within this list.
-
- - Variable: char * rl_filename_quote_characters
-     A list of characters that cause a filename to be quoted by the
-     completer when they appear in a completed filename.  The default
-     is the null string.
-
- - Variable: char * rl_special_prefixes
-     The list of characters that are word break characters, but should
-     be left in TEXT when it is passed to the completion function.
-     Programs can use this to help determine what kind of completing to
-     do.  For instance, Bash sets this variable to "$@" so that it can
-     complete shell variables and hostnames.
-
- - Variable: int rl_completion_append_character
-     When a single completion alternative matches at the end of the
-     command line, this character is appended to the inserted
-     completion text.  The default is a space character (` ').  Setting
-     this to the null character (`\0') prevents anything being appended
-     automatically.  This can be changed in custom completion functions
-     to provide the "most sensible word separator character" according
-     to an application-specific command line syntax specification.
-
- - Variable: int rl_ignore_completion_duplicates
-     If non-zero, then disallow duplicates in the matches.  Default is
-     1.
-
- - Variable: int rl_filename_completion_desired
-     Non-zero means that the results of the matches are to be treated as
-     filenames.  This is *always* zero on entry, and can only be changed
-     within a completion entry generator function.  If it is set to a
-     non-zero value, directory names have a slash appended and Readline
-     attempts to quote completed filenames if they contain any embedded
-     word break characters.
-
- - Variable: int rl_filename_quoting_desired
-     Non-zero means that the results of the matches are to be quoted
-     using double quotes (or an application-specific quoting mechanism)
-     if the completed filename contains any characters in
-     `rl_filename_quote_chars'.  This is *always* non-zero on entry,
-     and can only be changed within a completion entry generator
-     function.  The quoting is effected via a call to the function
-     pointed to by `rl_filename_quoting_function'.
-
- - Variable: int rl_inhibit_completion
-     If this variable is non-zero, completion is inhibit<ed.  The
-     completion character will be inserted as any other bound to
-     `self-insert'.
-
- - Variable: Function * rl_ignore_some_completions_function
-     This function, if defined, is called by the completer when real
-     filename completion is done, after all the matching names have
-     been generated.  It is passed a `NULL' terminated array of matches.
-     The first element (`matches[0]') is the maximal substring common
-     to all matches. This function can re-arrange the list of matches
-     as required, but each element deleted from the array must be freed.
-
- - Variable: Function * rl_directory_completion_hook
-     This function, if defined, is allowed to modify the directory
-     portion of filenames Readline completes.  It is called with the
-     address of a string (the current directory name) as an argument.
-     It could be used to expand symbolic links or shell variables in
-     pathnames.
-
- - Variable: VFunction * rl_completion_display_matches_hook
-     If non-zero, then this is the address of a function to call when
-     completing a word would normally display the list of possible
-     matches.  This function is called in lieu of Readline displaying
-     the list.  It takes three arguments: (`char **'MATCHES, `int'
-     NUM_MATCHES, `int' MAX_LENGTH) where MATCHES is the array of
-     matching strings, NUM_MATCHES is the number of strings in that
-     array, and MAX_LENGTH is the length of the longest string in that
-     array.  Readline provides a convenience function,
-     `rl_display_match_list', that takes care of doing the display to
-     Readline's output stream.  That function may be called from this
-     hook.

-<P>
-The following paragraphs describe the notation used to represent
-keystrokes.
-
-</P>
-<P>
-The text <KBD>C-k</KBD> is read as `Control-K' and describes the character
-produced when the <KBD>k</KBD> key is pressed while the Control key
-is depressed.
-
-</P>
-<P>
-The text <KBD>M-k</KBD> is read as `Meta-K' and describes the character
-produced when the Meta key (if you have one) is depressed, and the <KBD>k</KBD>
-key is pressed.
-The Meta key is labeled <KBD>ALT</KBD> on many keyboards.
-On keyboards with two keys labeled <KBD>ALT</KBD> (usually to either side of
-the space bar), the <KBD>ALT</KBD> on the left side is generally set to
-work as a Meta key.
-The <KBD>ALT</KBD> key on the right may also be configured to work as a
-Meta key or may be configured as some other modifier, such as a
-Compose key for typing accented characters.
-
-</P>
-<P>
-If you do not have a Meta or <KBD>ALT</KBD> key, or another key working as
-a Meta key, the identical keystroke can be generated by typing <KBD>ESC</KBD>
-<I>first</I>, and then typing <KBD>k</KBD>.
-Either process is known as <EM>metafying</EM> the <KBD>k</KBD> key.
-
-</P>
-<P>
-The text <KBD>M-C-k</KBD> is read as `Meta-Control-k' and describes the
-character produced by <EM>metafying</EM> <KBD>C-k</KBD>.
-
-</P>
-<P>
-In addition, several keys have their own names.  Specifically,
-<KBD>DEL</KBD>, <KBD>ESC</KBD>, <KBD>LFD</KBD>, <KBD>SPC</KBD>, <KBD>RET</KBD>, and <KBD>TAB</KBD> all
-stand for themselves when seen in this text, or in an init file
-(see section <A HREF="rluserman.html#SEC9">Readline Init File</A>).
-If your keyboard lacks a <KBD>LFD</KBD> key, typing <KBD>C-j</KBD> will
-produce the desired character.
-The <KBD>RET</KBD> key may be labeled <KBD>Return</KBD> or <KBD>Enter</KBD> on
-some keyboards.

-<P>
-Often during an interactive session you type in a long line of text,
-only to notice that the first word on the line is misspelled.  The
-Readline library gives you a set of commands for manipulating the text
-as you type it in, allowing you to just fix your typo, and not forcing
-you to retype the majority of the line.  Using these editing commands,
-you move the cursor to the place that needs correction, and delete or
-insert the text of the corrections.  Then, when you are satisfied with
-the line, you simply press <KBD>RETURN</KBD>.  You do not have to be at the
-end of the line to press <KBD>RETURN</KBD>; the entire line is accepted
-regardless of the location of the cursor within the line.

-In order to enter characters into the line, simply type them.  The typed
-character appears where the cursor was, and then the cursor moves one
-space to the right.  If you mistype a character, you can use your
-erase character to back up and delete the mistyped character.
-
-</P>
-<P>
-Sometimes you may mistype a character, and
-not notice the error until you have typed several other characters.  In
-that case, you can type <KBD>C-b</KBD> to move the cursor to the left, and then
-correct your mistake.  Afterwards, you can move the cursor to the right
-with <KBD>C-f</KBD>.
-
-</P>
-<P>

-<EM>Killing</EM> text means to delete the text from the line, but to save
-it away for later use, usually by <EM>yanking</EM> (re-inserting)
-it back into the line.
-(`Cut' and `paste' are more recent jargon for `kill' and `yank'.)

-place later.
-
-</P>
-<P>
-When you use a kill command, the text is saved in a <EM>kill-ring</EM>.
-Any number of consecutive kills save all of the killed text together, so
-that when you yank it back, you get it all.  The kill
-ring is not line specific; the text that you killed on a previously
-typed line is available to be yanked back later, when you are typing
-another line.

-Kill from the cursor to the end of the current word, or, if between
-words, to the end of the next word.
-Word boundaries are the same as those used by <KBD>M-f</KBD>.
-
-<DT><KBD>M-DEL</KBD>
-<DD>
-Kill from the cursor the start of the previous word, or, if between
-words, to the start of the previous word.
-Word boundaries are the same as those used by <KBD>M-b</KBD>.
-
-<DT><KBD>C-w</KBD>
-<DD>
-Kill from the cursor to the previous whitespace.  This is different than
-<KBD>M-DEL</KBD> because the word boundaries differ.
-

-<H3><A NAME="SEC7" HREF="rluserman.html#TOC7">Readline Arguments</A></H3>
-
-<P>
-You can pass numeric arguments to Readline commands.  Sometimes the
-argument acts as a repeat count, other times it is the <I>sign</I> of the
-argument that is significant.  If you pass a negative argument to a
-command which normally acts in a forward direction, that command will
-act in a backward direction.  For example, to kill text back to the
-start of the line, you might type <SAMP>`M-- C-k'</SAMP>.
-
-</P>
-<P>
-The general way to pass numeric arguments to a command is to type meta
-digits before the command.  If the first `digit' typed is a minus
-sign (<SAMP>`-'</SAMP>), then the sign of the argument will be negative.  Once
-you have typed one meta digit to get the argument started, you can type
-the remainder of the digits, and then the command.  For example, to give
-the <KBD>C-d</KBD> command an argument of 10, you could type <SAMP>`M-1 0 C-d'</SAMP>.

-<H3><A NAME="SEC8" HREF="rluserman.html#TOC8">Searching for Commands in the History</A></H3>
-
-<P>
-Readline provides commands for searching through the command history
-for lines containing a specified string.
-There are two search modes:  <VAR>incremental</VAR> and <VAR>non-incremental</VAR>.
-
-</P>
-<P>
-Incremental searches begin before the user has finished typing the
-search string.
-As each character of the search string is typed, Readline displays
-the next entry from the history matching the string typed so far.
-An incremental search requires only as many characters as needed to
-find the desired history entry.
-To search backward in the history for a particular string, type
-<KBD>C-r</KBD>.  Typing <KBD>C-s</KBD> searches forward through the history.
-The characters present in the value of the <CODE>isearch-terminators</CODE> variable
-are used to terminate an incremental search.
-If that variable has not been assigned a value, the <KBD>ESC</KBD> and
-<KBD>C-J</KBD> characters will terminate an incremental search.
-<KBD>C-g</KBD> will abort an incremental search and restore the original line.
-When the search is terminated, the history entry containing the
-search string becomes the current line.
-
-</P>
-<P>
-To find other matching entries in the history list, type <KBD>C-r</KBD> or
-<KBD>C-s</KBD> as appropriate.
-This will search backward or forward in the history for the next
-entry matching the search string typed so far.
-Any other key sequence bound to a Readline command will terminate
-the search and execute that command.
-For instance, a <KBD>RET</KBD> will terminate the search and accept
-the line, thereby executing the command from the history list.
-
-</P>
-<P>
-Non-incremental searches read the entire search string before starting
-to search for matching history lines.  The search string may be
-typed by the user or be part of the contents of the current line.

-A great deal of run-time behavior is changeable with the following
-variables.
-
-<DL COMPACT>
-
-<DT><CODE>bell-style</CODE>
-<DD>
-<A NAME="IDX9"></A>
-Controls what happens when Readline wants to ring the terminal bell.
-If set to <SAMP>`none'</SAMP>, Readline never rings the bell.  If set to
-<SAMP>`visible'</SAMP>, Readline uses a visible bell if one is available.
-If set to <SAMP>`audible'</SAMP> (the default), Readline attempts to ring
-the terminal's bell.
-
-<DT><CODE>comment-begin</CODE>
-<DD>
-<A NAME="IDX10"></A>
-The string to insert at the beginning of the line when the
-<CODE>insert-comment</CODE> command is executed.  The default value
-is <CODE>"#"</CODE>.
-
-<DT><CODE>completion-ignore-case</CODE>
-<DD>
-If set to <SAMP>`on'</SAMP>, Readline performs filename matching and completion
-in a case-insensitive fashion.
-The default value is <SAMP>`off'</SAMP>.
-
-<DT><CODE>completion-query-items</CODE>
-<DD>
-<A NAME="IDX11"></A>
-The number of possible completions that determines when the user is
-asked whether he wants to see the list of possibilities.  If the
-number of possible completions is greater than this value,
-Readline will ask the user whether or not he wishes to view
-them; otherwise, they are simply listed.  The default limit is
-<CODE>100</CODE>.
-
-<DT><CODE>convert-meta</CODE>
-<DD>
-<A NAME="IDX12"></A>
-If set to <SAMP>`on'</SAMP>, Readline will convert characters with the
-eighth bit set to an ASCII key sequence by stripping the eighth
-bit and prefixing an <KBD>ESC</KBD> character, converting them to a
-meta-prefixed key sequence.  The default value is <SAMP>`on'</SAMP>.
-
-<DT><CODE>disable-completion</CODE>
-<DD>
-<A NAME="IDX13"></A>
-If set to <SAMP>`On'</SAMP>, Readline will inhibit word completion.
-Completion  characters will be inserted into the line as if they had
-been mapped to <CODE>self-insert</CODE>.  The default is <SAMP>`off'</SAMP>.
-
-<DT><CODE>editing-mode</CODE>
-<DD>
-<A NAME="IDX14"></A>
-The <CODE>editing-mode</CODE> variable controls which default set of
-key bindings is used.  By default, Readline starts up in Emacs editing
-mode, where the keystrokes are most similar to Emacs.  This variable can be
-set to either <SAMP>`emacs'</SAMP> or <SAMP>`vi'</SAMP>.
-
-<DT><CODE>enable-keypad</CODE>
-<DD>
-<A NAME="IDX15"></A>
-When set to <SAMP>`on'</SAMP>, Readline will try to enable the application
-keypad when it is called.  Some systems need this to enable the
-arrow keys.  The default is <SAMP>`off'</SAMP>.
-
-<DT><CODE>expand-tilde</CODE>
-<DD>
-<A NAME="IDX16"></A>
-If set to <SAMP>`on'</SAMP>, tilde expansion is performed when Readline
-attempts word completion.  The default is <SAMP>`off'</SAMP>.
-
-<DT><CODE>horizontal-scroll-mode</CODE>
-<DD>
-<A NAME="IDX17"></A>
-This variable can be set to either <SAMP>`on'</SAMP> or <SAMP>`off'</SAMP>.  Setting it
-to <SAMP>`on'</SAMP> means that the text of the lines being edited will scroll
-horizontally on a single screen line when they are longer than the width
-of the screen, instead of wrapping onto a new screen line.  By default,
-this variable is set to <SAMP>`off'</SAMP>.
-
-<DT><CODE>input-meta</CODE>
-<DD>
-<A NAME="IDX18"></A>
-<A NAME="IDX19"></A>
-If set to <SAMP>`on'</SAMP>, Readline will enable eight-bit input (it
-will not strip the eighth bit from the characters it reads),
-regardless of what the terminal claims it can support.  The
-default value is <SAMP>`off'</SAMP>.  The name <CODE>meta-flag</CODE> is a
-synonym for this variable.
-
-<DT><CODE>isearch-terminators</CODE>
-<DD>
-<A NAME="IDX20"></A>
-The string of characters that should terminate an incremental search without
-subsequently executing the character as a command (see section <A HREF="rluserman.html#SEC8">Searching for Commands in the History</A>).
-If this variable has not been given a value, the characters <KBD>ESC</KBD> and
-<KBD>C-J</KBD> will terminate an incremental search.
-
-<DT><CODE>keymap</CODE>
-<DD>
-<A NAME="IDX21"></A>
-Sets Readline's idea of the current keymap for key binding commands.
-Acceptable <CODE>keymap</CODE> names are
-<CODE>emacs</CODE>,
-<CODE>emacs-standard</CODE>,
-<CODE>emacs-meta</CODE>,
-<CODE>emacs-ctlx</CODE>,
-<CODE>vi</CODE>,
-<CODE>vi-command</CODE>, and
-<CODE>vi-insert</CODE>.
-<CODE>vi</CODE> is equivalent to <CODE>vi-command</CODE>; <CODE>emacs</CODE> is
-equivalent to <CODE>emacs-standard</CODE>.  The default value is <CODE>emacs</CODE>.
-The value of the <CODE>editing-mode</CODE> variable also affects the
-default keymap.
-
-<DT><CODE>mark-directories</CODE>
-<DD>
-If set to <SAMP>`on'</SAMP>, completed directory names have a slash
-appended.  The default is <SAMP>`on'</SAMP>.
-
-<DT><CODE>mark-modified-lines</CODE>
-<DD>
-<A NAME="IDX22"></A>
-This variable, when set to <SAMP>`on'</SAMP>, causes Readline to display an
-asterisk (<SAMP>`*'</SAMP>) at the start of history lines which have been modified.
-This variable is <SAMP>`off'</SAMP> by default.
-
-<DT><CODE>output-meta</CODE>
-<DD>
-<A NAME="IDX23"></A>
-If set to <SAMP>`on'</SAMP>, Readline will display characters with the
-eighth bit set directly rather than as a meta-prefixed escape
-sequence.  The default is <SAMP>`off'</SAMP>.
-
-<DT><CODE>print-completions-horizontally</CODE>
-<DD>
-If set to <SAMP>`on'</SAMP>, Readline will display completions with matches
-sorted horizontally in alphabetical order, rather than down the screen.
-The default is <SAMP>`off'</SAMP>.
-
-<DT><CODE>show-all-if-ambiguous</CODE>
-<DD>
-<A NAME="IDX24"></A>
-This alters the default behavior of the completion functions.  If
-set to <SAMP>`on'</SAMP>, 
-words which have more than one possible completion cause the
-matches to be listed immediately instead of ringing the bell.
-The default value is <SAMP>`off'</SAMP>.
-
-<DT><CODE>visible-stats</CODE>
-<DD>
-<A NAME="IDX25"></A>
-If set to <SAMP>`on'</SAMP>, a character denoting a file's type
-is appended to the filename when listing possible
-completions.  The default is <SAMP>`off'</SAMP>.

-<DT>Key Bindings
-<DD>
-The syntax for controlling key bindings in the init file is
-simple.  First you need to find the name of the command that you
-want to change.  The following sections contain tables of the command
-name, the default keybinding, if any, and a short description of what
-the command does.
-
-Once you know the name of the command, simply place the name of the key
-you wish to bind the command to, a colon, and then the name of the
-command on a line in the init file.  The name of the key
-can be expressed in different ways, depending on which is most
-comfortable for you.
-
-<DL COMPACT>
-
-<DT><VAR>keyname</VAR>: <VAR>function-name</VAR> or <VAR>macro</VAR>

-<VAR>keyname</VAR> is the name of a key spelled out in English.  For example:
-
-<PRE>
-Control-u: universal-argument
-Meta-Rubout: backward-kill-word
-Control-o: "&#62; output"
-</PRE>
-
-In the above example, <KBD>C-u</KBD> is bound to the function
-<CODE>universal-argument</CODE>, and <KBD>C-o</KBD> is bound to run the macro
-expressed on the right hand side (that is, to insert the text
-<SAMP>`&#62; output'</SAMP> into the line).
-
-<DT>"<VAR>keyseq</VAR>": <VAR>function-name</VAR> or <VAR>macro</VAR>
-<DD>
-<VAR>keyseq</VAR> differs from <VAR>keyname</VAR> above in that strings
-denoting an entire key sequence can be specified, by placing
-the key sequence in double quotes.  Some GNU Emacs style key
-escapes can be used, as in the following example, but the
-special character names are not recognized.
-

-"\C-u": universal-argument
-"\C-x\C-r": re-read-init-file

-In the above example, <KBD>C-u</KBD> is bound to the function
-<CODE>universal-argument</CODE> (just as it was in the first example),
-<SAMP>`<KBD>C-x</KBD> <KBD>C-r</KBD>'</SAMP> is bound to the function <CODE>re-read-init-file</CODE>,
-and <SAMP>`<KBD>ESC</KBD> <KBD>[</KBD> <KBD>1</KBD> <KBD>1</KBD> <KBD>~</KBD>'</SAMP> is bound to insert
-the text <SAMP>`Function Key 1'</SAMP>.

-Unquoted text is assumed to be a function name.
-In the macro body, the backslash escapes described above are expanded.
-Backslash will quote any other character in the macro text,
-including <SAMP>`"'</SAMP> and <SAMP>`''</SAMP>.
-For example, the following binding will make <SAMP>`C-x \'</SAMP>

-Readline implements a facility similar in spirit to the conditional
-compilation features of the C preprocessor which allows key
-bindings and variable settings to be performed as the result
-of tests.  There are four parser directives used.
-
-</P>
-<DL COMPACT>
-
-<DT><CODE>$if</CODE>
-<DD>
-The <CODE>$if</CODE> construct allows bindings to be made based on the
-editing mode, the terminal being used, or the application using
-Readline.  The text of the test extends to the end of the line;
-no characters are required to isolate it.
-
-<DL COMPACT>
-
-<DT><CODE>mode</CODE>
-<DD>
-The <CODE>mode=</CODE> form of the <CODE>$if</CODE> directive is used to test
-whether Readline is in <CODE>emacs</CODE> or <CODE>vi</CODE> mode.
-This may be used in conjunction
-with the <SAMP>`set keymap'</SAMP> command, for instance, to set bindings in
-the <CODE>emacs-standard</CODE> and <CODE>emacs-ctlx</CODE> keymaps only if
-Readline is starting out in <CODE>emacs</CODE> mode.
-
-<DT><CODE>term</CODE>
-<DD>
-The <CODE>term=</CODE> form may be used to include terminal-specific
-key bindings, perhaps to bind the key sequences output by the
-terminal's function keys.  The word on the right side of the
-<SAMP>`='</SAMP> is tested against both the full name of the terminal and
-the portion of the terminal name before the first <SAMP>`-'</SAMP>.  This
-allows <CODE>sun</CODE> to match both <CODE>sun</CODE> and <CODE>sun-cmd</CODE>,
-for instance.
-
-<DT><CODE>application</CODE>
-<DD>
-The <VAR>application</VAR> construct is used to include
-application-specific settings.  Each program using the Readline
-library sets the <VAR>application name</VAR>, and you can test for it. 
-This could be used to bind key sequences to functions useful for
-a specific program.  For instance, the following command adds a
-key sequence that quotes the current or previous word in Bash:
-
-<PRE>
-$if Bash
-# Quote the current or previous word
-"\C-xq": "\eb\"\ef\""
-$endif
-</PRE>
-
-</DL>
-
-<DT><CODE>$endif</CODE>

-This command, as seen in the previous example, terminates an
-<CODE>$if</CODE> command.
-

-<DD>
-Commands in this branch of the <CODE>$if</CODE> directive are executed if
-the test fails.

-Introduction to Line Editing
-============================
-
-   The following paragraphs describe the notation used to represent
-keystrokes.
-
-   The text <C-k> is read as `Control-K' and describes the character
-produced when the <k> key is pressed while the Control key is depressed.
-
-   The text <M-k> is read as `Meta-K' and describes the character
-produced when the Meta key (if you have one) is depressed, and the <k>
-key is pressed.  The Meta key is labeled <ALT> on many keyboards.  On
-keyboards with two keys labeled <ALT> (usually to either side of the
-space bar), the <ALT> on the left side is generally set to work as a
-Meta key.  The <ALT> key on the right may also be configured to work as
-a Meta key or may be configured as some other modifier, such as a
-Compose key for typing accented characters.
-
-   If you do not have a Meta or <ALT> key, or another key working as a
-Meta key, the identical keystroke can be generated by typing <ESC>
-first, and then typing <k>.  Either process is known as "metafying" the
-<k> key.
-
-   The text <M-C-k> is read as `Meta-Control-k' and describes the
-character produced by "metafying" <C-k>.
-
-   In addition, several keys have their own names.  Specifically,
-<DEL>, <ESC>, <LFD>, <SPC>, <RET>, and <TAB> all stand for themselves
-when seen in this text, or in an init file (*note Readline Init
-File::.).  If your keyboard lacks a <LFD> key, typing <C-j> will
-produce the desired character.  The <RET> key may be labeled <Return>
-or <Enter> on some keyboards.

-Readline Interaction
-====================
-
-   Often during an interactive session you type in a long line of text,
-only to notice that the first word on the line is misspelled.  The
-Readline library gives you a set of commands for manipulating the text
-as you type it in, allowing you to just fix your typo, and not forcing
-you to retype the majority of the line.  Using these editing commands,
-you move the cursor to the place that needs correction, and delete or
-insert the text of the corrections.  Then, when you are satisfied with
-the line, you simply press <RETURN>.  You do not have to be at the end
-of the line to press <RETURN>; the entire line is accepted regardless
-of the location of the cursor within the line.

-Readline Bare Essentials
-------------------------
-
-   In order to enter characters into the line, simply type them.  The
-typed character appears where the cursor was, and then the cursor moves
-one space to the right.  If you mistype a character, you can use your
-erase character to back up and delete the mistyped character.
-
-   Sometimes you may mistype a character, and not notice the error
-until you have typed several other characters.  In that case, you can
-type <C-b> to move the cursor to the left, and then correct your
-mistake.  Afterwards, you can move the cursor to the right with <C-f>.
-
-   When you add text in the middle of a line, you will notice that
-characters to the right of the cursor are `pushed over' to make room
-for the text that you have inserted.  Likewise, when you delete text
-behind the cursor, characters to the right of the cursor are `pulled
-back' to fill in the blank space created by the removal of the text.  A
-list of the bare essentials for editing the text of an input line
-follows.
-
-<C-b>
-     Move back one character.
-
-<C-f>
-     Move forward one character.
-
-<DEL> or <Backspace>
-     Delete the character to the left of the cursor.
-
-<C-d>
-     Delete the character underneath the cursor.
-
-Printing characters
-     Insert the character into the line at the cursor.
-
-<C-_> or <C-x C-u>
-     Undo the last editing command.  You can undo all the way back to an
-     empty line.
-
-(Depending on your configuration, the <Backspace> key be set to delete
-the character to the left of the cursor and the <DEL> key set to delete
-the character underneath the cursor, like <C-d>, rather than the
-character to the left of the cursor.)

-
-Readline Movement Commands
---------------------------
-
-   The above table describes the most basic keystrokes that you need in
-order to do editing of the input line.  For your convenience, many
-other commands have been added in addition to <C-b>, <C-f>, <C-d>, and
-<DEL>.  Here are some commands for moving more rapidly about the line.
-
-<C-a>
-     Move to the start of the line.
-
-<C-e>
-     Move to the end of the line.
-
-<M-f>
-     Move forward a word, where a word is composed of letters and
-     digits.
-
-<M-b>
-     Move backward a word.
-
-<C-l>
-     Clear the screen, reprinting the current line at the top.
-
-   Notice how <C-f> moves forward a character, while <M-f> moves
-forward a word.  It is a loose convention that control keystrokes
-operate on characters while meta keystrokes operate on words.

-Readline Killing Commands
--------------------------
-
-   "Killing" text means to delete the text from the line, but to save
-it away for later use, usually by "yanking" (re-inserting) it back into
-the line.  (`Cut' and `paste' are more recent jargon for `kill' and
-`yank'.)
-
-   If the description for a command says that it `kills' text, then you
-can be sure that you can get the text back in a different (or the same)
-place later.
-
-   When you use a kill command, the text is saved in a "kill-ring".
-Any number of consecutive kills save all of the killed text together, so
-that when you yank it back, you get it all.  The kill ring is not line
-specific; the text that you killed on a previously typed line is
-available to be yanked back later, when you are typing another line.
-
-   Here is the list of commands for killing text.
-
-<C-k>
-     Kill the text from the current cursor position to the end of the
-     line.
-
-<M-d>
-     Kill from the cursor to the end of the current word, or, if between
-     words, to the end of the next word.  Word boundaries are the same
-     as those used by <M-f>.
-
-<M-DEL>
-     Kill from the cursor the start of the previous word, or, if between
-     words, to the start of the previous word.  Word boundaries are the
-     same as those used by <M-b>.
-
-<C-w>
-     Kill from the cursor to the previous whitespace.  This is
-     different than <M-DEL> because the word boundaries differ.
-
-   Here is how to "yank" the text back into the line.  Yanking means to
-copy the most-recently-killed text from the kill buffer.
-
-<C-y>
-     Yank the most recently killed text back into the buffer at the
-     cursor.
-
-<M-y>
-     Rotate the kill-ring, and yank the new top.  You can only do this
-     if the prior command is <C-y> or <M-y>.
-
-

-
-Readline Arguments
-------------------
-
-   You can pass numeric arguments to Readline commands.  Sometimes the
-argument acts as a repeat count, other times it is the sign of the
-argument that is significant.  If you pass a negative argument to a
-command which normally acts in a forward direction, that command will
-act in a backward direction.  For example, to kill text back to the
-start of the line, you might type `M-- C-k'.
-
-   The general way to pass numeric arguments to a command is to type
-meta digits before the command.  If the first `digit' typed is a minus
-sign (`-'), then the sign of the argument will be negative.  Once you
-have typed one meta digit to get the argument started, you can type the
-remainder of the digits, and then the command.  For example, to give
-the <C-d> command an argument of 10, you could type `M-1 0 C-d'.
-
-
-File: rluserman.info,  Node: Searching,  Prev: Readline Arguments,  Up: Readline Interaction
-
-Searching for Commands in the History
--------------------------------------
-
-   Readline provides commands for searching through the command history
-for lines containing a specified string.  There are two search modes:
-INCREMENTAL and NON-INCREMENTAL.
-
-   Incremental searches begin before the user has finished typing the
-search string.  As each character of the search string is typed,
-Readline displays the next entry from the history matching the string
-typed so far.  An incremental search requires only as many characters
-as needed to find the desired history entry.  To search backward in the
-history for a particular string, type <C-r>.  Typing <C-s> searches
-forward through the history.  The characters present in the value of
-the `isearch-terminators' variable are used to terminate an incremental
-search.  If that variable has not been assigned a value, the <ESC> and
-<C-J> characters will terminate an incremental search.  <C-g> will
-abort an incremental search and restore the original line.  When the
-search is terminated, the history entry containing the search string
-becomes the current line.
-
-   To find other matching entries in the history list, type <C-r> or
-<C-s> as appropriate.  This will search backward or forward in the
-history for the next entry matching the search string typed so far.
-Any other key sequence bound to a Readline command will terminate the
-search and execute that command.  For instance, a <RET> will terminate
-the search and accept the line, thereby executing the command from the
-history list.
-
-   Non-incremental searches read the entire search string before
-starting to search for matching history lines.  The search string may be
-typed by the user or be part of the contents of the current line.

-Readline Init File
-==================
-
-   Although the Readline library comes with a set of Emacs-like
-keybindings installed by default, it is possible to use a different set
-of keybindings.  Any user can customize programs that use Readline by
-putting commands in an "inputrc" file, conventionally in his home
-directory.  The name of this file is taken from the value of the
-environment variable `INPUTRC'.  If that variable is unset, the default
-is `~/.inputrc'.
-
-   When a program which uses the Readline library starts up, the init
-file is read, and the key bindings are set.
-
-   In addition, the `C-x C-r' command re-reads this init file, thus
-incorporating any changes that you might have made to it.

-
-* Sample Init File::		An example inputrc file.
-
-
-File: rluserman.info,  Node: Readline Init File Syntax,  Next: Conditional Init Constructs,  Up: Readline Init File
-
-Readline Init File Syntax
--------------------------
-
-   There are only a few basic constructs allowed in the Readline init
-file.  Blank lines are ignored.  Lines beginning with a `#' are
-comments.  Lines beginning with a `$' indicate conditional constructs
-(*note Conditional Init Constructs::.).  Other lines denote variable
-settings and key bindings.
-
-Variable Settings
-     You can modify the run-time behavior of Readline by altering the
-     values of variables in Readline using the `set' command within the
-     init file.  Here is how to change from the default Emacs-like key
-     binding to use `vi' line editing commands:
-
-          set editing-mode vi
-
-     A great deal of run-time behavior is changeable with the following
-     variables.
-
-    `bell-style'
-          Controls what happens when Readline wants to ring the
-          terminal bell.  If set to `none', Readline never rings the
-          bell.  If set to `visible', Readline uses a visible bell if
-          one is available.  If set to `audible' (the default),
-          Readline attempts to ring the terminal's bell.
-
-    `comment-begin'
-          The string to insert at the beginning of the line when the
-          `insert-comment' command is executed.  The default value is
-          `"#"'.
-
-    `completion-ignore-case'
-          If set to `on', Readline performs filename matching and
-          completion in a case-insensitive fashion.  The default value
-          is `off'.
-
-    `completion-query-items'
-          The number of possible completions that determines when the
-          user is asked whether he wants to see the list of
-          possibilities.  If the number of possible completions is
-          greater than this value, Readline will ask the user whether
-          or not he wishes to view them; otherwise, they are simply
-          listed.  The default limit is `100'.
-
-    `convert-meta'
-          If set to `on', Readline will convert characters with the
-          eighth bit set to an ASCII key sequence by stripping the
-          eighth bit and prefixing an <ESC> character, converting them
-          to a meta-prefixed key sequence.  The default value is `on'.
-
-    `disable-completion'
-          If set to `On', Readline will inhibit word completion.
-          Completion  characters will be inserted into the line as if
-          they had been mapped to `self-insert'.  The default is `off'.
-
-    `editing-mode'
-          The `editing-mode' variable controls which default set of key
-          bindings is used.  By default, Readline starts up in Emacs
-          editing mode, where the keystrokes are most similar to Emacs.
-          This variable can be set to either `emacs' or `vi'.
-
-    `enable-keypad'
-          When set to `on', Readline will try to enable the application
-          keypad when it is called.  Some systems need this to enable
-          the arrow keys.  The default is `off'.
-
-    `expand-tilde'
-          If set to `on', tilde expansion is performed when Readline
-          attempts word completion.  The default is `off'.
-
-    `horizontal-scroll-mode'
-          This variable can be set to either `on' or `off'.  Setting it
-          to `on' means that the text of the lines being edited will
-          scroll horizontally on a single screen line when they are
-          longer than the width of the screen, instead of wrapping onto
-          a new screen line.  By default, this variable is set to `off'.
-
-    `input-meta'
-          If set to `on', Readline will enable eight-bit input (it will
-          not strip the eighth bit from the characters it reads),
-          regardless of what the terminal claims it can support.  The
-          default value is `off'.  The name `meta-flag' is a synonym
-          for this variable.
-
-    `isearch-terminators'
-          The string of characters that should terminate an incremental
-          search without subsequently executing the character as a
-          command (*note Searching::.).  If this variable has not been
-          given a value, the characters <ESC> and <C-J> will terminate
-          an incremental search.
-
-    `keymap'
-          Sets Readline's idea of the current keymap for key binding
-          commands.  Acceptable `keymap' names are `emacs',
-          `emacs-standard', `emacs-meta', `emacs-ctlx', `vi',
-          `vi-command', and `vi-insert'.  `vi' is equivalent to
-          `vi-command'; `emacs' is equivalent to `emacs-standard'.  The
-          default value is `emacs'.  The value of the `editing-mode'
-          variable also affects the default keymap.
-
-    `mark-directories'
-          If set to `on', completed directory names have a slash
-          appended.  The default is `on'.
-
-    `mark-modified-lines'
-          This variable, when set to `on', causes Readline to display an
-          asterisk (`*') at the start of history lines which have been
-          modified.  This variable is `off' by default.
-
-    `output-meta'
-          If set to `on', Readline will display characters with the
-          eighth bit set directly rather than as a meta-prefixed escape
-          sequence.  The default is `off'.
-
-    `print-completions-horizontally'
-          If set to `on', Readline will display completions with matches
-          sorted horizontally in alphabetical order, rather than down
-          the screen.  The default is `off'.
-
-    `show-all-if-ambiguous'
-          This alters the default behavior of the completion functions.
-          If set to `on', words which have more than one possible
-          completion cause the matches to be listed immediately instead
-          of ringing the bell.  The default value is `off'.
-
-    `visible-stats'
-          If set to `on', a character denoting a file's type is
-          appended to the filename when listing possible completions.
-          The default is `off'.
-
-Key Bindings
-     The syntax for controlling key bindings in the init file is
-     simple.  First you need to find the name of the command that you
-     want to change.  The following sections contain tables of the
-     command name, the default keybinding, if any, and a short
-     description of what the command does.
-
-     Once you know the name of the command, simply place the name of
-     the key you wish to bind the command to, a colon, and then the
-     name of the command on a line in the init file.  The name of the
-     key can be expressed in different ways, depending on which is most
-     comfortable for you.
-
-    KEYNAME: FUNCTION-NAME or MACRO
-          KEYNAME is the name of a key spelled out in English.  For
-          example:
-               Control-u: universal-argument
-               Meta-Rubout: backward-kill-word
-               Control-o: "> output"
-
-          In the above example, <C-u> is bound to the function
-          `universal-argument', and <C-o> is bound to run the macro
-          expressed on the right hand side (that is, to insert the text
-          `> output' into the line).
-
-    "KEYSEQ": FUNCTION-NAME or MACRO
-          KEYSEQ differs from KEYNAME above in that strings denoting an
-          entire key sequence can be specified, by placing the key
-          sequence in double quotes.  Some GNU Emacs style key escapes
-          can be used, as in the following example, but the special
-          character names are not recognized.
-
-               "\C-u": universal-argument
-               "\C-x\C-r": re-read-init-file
-               "\e[11~": "Function Key 1"
-
-          In the above example, <C-u> is bound to the function
-          `universal-argument' (just as it was in the first example),
-          `<C-x> <C-r>' is bound to the function `re-read-init-file',
-          and `<ESC> <[> <1> <1> <~>' is bound to insert the text
-          `Function Key 1'.
-
-     The following GNU Emacs style escape sequences are available when
-     specifying key sequences:
-
-    `\C-'
-          control prefix
-
-    `\M-'
-          meta prefix
-
-    `\e'
-          an escape character
-
-    `\\'
-          backslash
-
-    `\"'
-          <">, a double quotation mark
-
-    `\''
-          <'>, a single quote or apostrophe
-
-     In addition to the GNU Emacs style escape sequences, a second set
-     of backslash escapes is available:
-
-    `\a'
-          alert (bell)
-
-    `\b'
-          backspace
-
-    `\d'
-          delete
-
-    `\f'
-          form feed
-
-    `\n'
-          newline
-
-    `\r'
-          carriage return
-
-    `\t'
-          horizontal tab
-
-    `\v'
-          vertical tab
-
-    `\NNN'
-          the character whose `ASCII' code is the octal value NNN (one
-          to three digits)
-
-    `\xNNN'
-          the character whose `ASCII' code is the hexadecimal value NNN
-          (one to three digits)
-
-     When entering the text of a macro, single or double quotes must be
-     used to indicate a macro definition.  Unquoted text is assumed to
-     be a function name.  In the macro body, the backslash escapes
-     described above are expanded.  Backslash will quote any other
-     character in the macro text, including `"' and `''.  For example,
-     the following binding will make `C-x \' insert a single `\' into
-     the line:
-          "\C-x\\": "\\"

-Conditional Init Constructs
----------------------------
-
-   Readline implements a facility similar in spirit to the conditional
-compilation features of the C preprocessor which allows key bindings
-and variable settings to be performed as the result of tests.  There
-are four parser directives used.
-
-`$if'
-     The `$if' construct allows bindings to be made based on the
-     editing mode, the terminal being used, or the application using
-     Readline.  The text of the test extends to the end of the line; no
-     characters are required to isolate it.
-
-    `mode'
-          The `mode=' form of the `$if' directive is used to test
-          whether Readline is in `emacs' or `vi' mode.  This may be
-          used in conjunction with the `set keymap' command, for
-          instance, to set bindings in the `emacs-standard' and
-          `emacs-ctlx' keymaps only if Readline is starting out in
-          `emacs' mode.
-
-    `term'
-          The `term=' form may be used to include terminal-specific key
-          bindings, perhaps to bind the key sequences output by the
-          terminal's function keys.  The word on the right side of the
-          `=' is tested against both the full name of the terminal and
-          the portion of the terminal name before the first `-'.  This
-          allows `sun' to match both `sun' and `sun-cmd', for instance.
-
-    `application'
-          The APPLICATION construct is used to include
-          application-specific settings.  Each program using the
-          Readline library sets the APPLICATION NAME, and you can test
-          for it.  This could be used to bind key sequences to
-          functions useful for a specific program.  For instance, the
-          following command adds a key sequence that quotes the current
-          or previous word in Bash:
-               $if Bash
-               # Quote the current or previous word
-               "\C-xq": "\eb\"\ef\""
-               $endif
-
-`$endif'
-     This command, as seen in the previous example, terminates an `$if'
-     command.
-
-`$else'
-     Commands in this branch of the `$if' directive are executed if the
-     test fails.
-
-`$include'
-     This directive takes a single filename as an argument and reads
-     commands and bindings from that file.
-          $include /etc/inputrc

-
-Commands For Manipulating The History
--------------------------------------
-
-`accept-line (Newline, Return)'
-     Accept the line regardless of where the cursor is.  If this line is
-     non-empty, add it to the history list.  If this line was a history
-     line, then restore the history line to its original state.
-
-`previous-history (C-p)'
-     Move `up' through the history list.
-
-`next-history (C-n)'
-     Move `down' through the history list.
-
-`beginning-of-history (M-<)'
-     Move to the first line in the history.
-
-`end-of-history (M->)'
-     Move to the end of the input history, i.e., the line currently
-     being entered.
-
-`reverse-search-history (C-r)'
-     Search backward starting at the current line and moving `up'
-     through the history as necessary.  This is an incremental search.
-
-`forward-search-history (C-s)'
-     Search forward starting at the current line and moving `down'
-     through the the history as necessary.  This is an incremental
-     search.
-
-`non-incremental-reverse-search-history (M-p)'
-     Search backward starting at the current line and moving `up'
-     through the history as necessary using a non-incremental search
-     for a string supplied by the user.
-
-`non-incremental-forward-search-history (M-n)'
-     Search forward starting at the current line and moving `down'
-     through the the history as necessary using a non-incremental search
-     for a string supplied by the user.
-
-`history-search-forward ()'
-     Search forward through the history for the string of characters
-     between the start of the current line and the point.  This is a
-     non-incremental search.  By default, this command is unbound.
-
-`history-search-backward ()'
-     Search backward through the history for the string of characters
-     between the start of the current line and the point.  This is a
-     non-incremental search.  By default, this command is unbound.
-
-`yank-nth-arg (M-C-y)'
-     Insert the first argument to the previous command (usually the
-     second word on the previous line).  With an argument N, insert the
-     Nth word from the previous command (the words in the previous
-     command begin with word 0).  A negative argument inserts the Nth
-     word from the end of the previous command.
-
-`yank-last-arg (M-., M-_)'
-     Insert last argument to the previous command (the last word of the
-     previous history entry).  With an argument, behave exactly like
-     `yank-nth-arg'.  Successive calls to `yank-last-arg' move back
-     through the history list, inserting the last argument of each line
-     in turn.

-
-Commands For Changing Text
---------------------------
-
-`delete-char (C-d)'
-     Delete the character under the cursor.  If the cursor is at the
-     beginning of the line, there are no characters in the line, and
-     the last character typed was not bound to `delete-char', then
-     return `EOF'.
-
-`backward-delete-char (Rubout)'
-     Delete the character behind the cursor.  A numeric argument means
-     to kill the characters instead of deleting them.
-
-`forward-backward-delete-char ()'
-     Delete the character under the cursor, unless the cursor is at the
-     end of the line, in which case the character behind the cursor is
-     deleted.  By default, this is not bound to a key.
-
-`quoted-insert (C-q, C-v)'
-     Add the next character typed to the line verbatim.  This is how to
-     insert key sequences like <C-q>, for example.
-
-`tab-insert (M-TAB)'
-     Insert a tab character.
-
-`self-insert (a, b, A, 1, !, ...)'
-     Insert yourself.
-
-`transpose-chars (C-t)'
-     Drag the character before the cursor forward over the character at
-     the cursor, moving the cursor forward as well.  If the insertion
-     point is at the end of the line, then this transposes the last two
-     characters of the line.  Negative arguments have no effect.
-
-`transpose-words (M-t)'
-     Drag the word before point past the word after point, moving point
-     past that word as well.
-
-`upcase-word (M-u)'
-     Uppercase the current (or following) word.  With a negative
-     argument, uppercase the previous word, but do not move the cursor.
-
-`downcase-word (M-l)'
-     Lowercase the current (or following) word.  With a negative
-     argument, lowercase the previous word, but do not move the cursor.
-
-`capitalize-word (M-c)'
-     Capitalize the current (or following) word.  With a negative
-     argument, capitalize the previous word, but do not move the cursor.

-
-Killing And Yanking
--------------------
-
-`kill-line (C-k)'
-     Kill the text from point to the end of the line.
-
-`backward-kill-line (C-x Rubout)'
-     Kill backward to the beginning of the line.
-
-`unix-line-discard (C-u)'
-     Kill backward from the cursor to the beginning of the current line.
-
-`kill-whole-line ()'
-     Kill all characters on the current line, no matter point is.  By
-     default, this is unbound.
-
-`kill-word (M-d)'
-     Kill from point to the end of the current word, or if between
-     words, to the end of the next word.  Word boundaries are the same
-     as `forward-word'.
-
-`backward-kill-word (M-DEL)'
-     Kill the word behind point.  Word boundaries are the same as
-     `backward-word'.
-
-`unix-word-rubout (C-w)'
-     Kill the word behind point, using white space as a word boundary.
-     The killed text is saved on the kill-ring.
-
-`delete-horizontal-space ()'
-     Delete all spaces and tabs around point.  By default, this is
-     unbound.
-
-`kill-region ()'
-     Kill the text in the current region.  By default, this command is
-     unbound.
-
-`copy-region-as-kill ()'
-     Copy the text in the region to the kill buffer, so it can be yanked
-     right away.  By default, this command is unbound.
-
-`copy-backward-word ()'
-     Copy the word before point to the kill buffer.  The word
-     boundaries are the same as `backward-word'.  By default, this
-     command is unbound.
-
-`copy-forward-word ()'
-     Copy the word following point to the kill buffer.  The word
-     boundaries are the same as `forward-word'.  By default, this
-     command is unbound.
-
-`yank (C-y)'
-     Yank the top of the kill ring into the buffer at the current
-     cursor position.
-
-`yank-pop (M-y)'
-     Rotate the kill-ring, and yank the new top.  You can only do this
-     if the prior command is yank or yank-pop.
-
-
-File: rluserman.info,  Node: Numeric Arguments,  Next: Commands For Completion,  Prev: Commands For Killing,  Up: Bindable Readline Commands
-
-Specifying Numeric Arguments
-----------------------------
-
-`digit-argument (M-0, M-1, ... M--)'
-     Add this digit to the argument already accumulating, or start a new
-     argument.  <M-> starts a negative argument.
-
-`universal-argument ()'
-     This is another way to specify an argument.  If this command is
-     followed by one or more digits, optionally with a leading minus
-     sign, those digits define the argument.  If the command is
-     followed by digits, executing `universal-argument' again ends the
-     numeric argument, but is otherwise ignored.  As a special case, if
-     this command is immediately followed by a character that is
-     neither a digit or minus sign, the argument count for the next
-     command is multiplied by four.  The argument count is initially
-     one, so executing this function the first time makes the argument
-     count four, a second time makes the argument count sixteen, and so
-     on.  By default, this is not bound to a key.
-

-
-Letting Readline Type For You
------------------------------
-
-`complete (TAB)'
-     Attempt to do completion on the text before the cursor.  This is
-     application-specific.  Generally, if you are typing a filename
-     argument, you can do filename completion; if you are typing a
-     command, you can do command completion; if you are typing in a
-     symbol to GDB, you can do symbol name completion; if you are
-     typing in a variable to Bash, you can do variable name completion,
-     and so on.
-
-`possible-completions (M-?)'
-     List the possible completions of the text before the cursor.
-
-`insert-completions (M-*)'
-     Insert all completions of the text before point that would have
-     been generated by `possible-completions'.
-
-`menu-complete ()'
-     Similar to `complete', but replaces the word to be completed with
-     a single match from the list of possible completions.  Repeated
-     execution of `menu-complete' steps through the list of possible
-     completions, inserting each match in turn.  At the end of the list
-     of completions, the bell is rung and the original text is restored.
-     An argument of N moves N positions forward in the list of matches;
-     a negative argument may be used to move backward through the list.
-     This command is intended to be bound to `TAB', but is unbound by
-     default.
-
-`delete-char-or-list ()'
-     Deletes the character under the cursor if not at the beginning or
-     end of the line (like `delete-char').  If at the end of the line,
-     behaves identically to `possible-completions'.  This command is
-     unbound by default.

-
-Keyboard Macros
----------------
-
-`start-kbd-macro (C-x ()'
-     Begin saving the characters typed into the current keyboard macro.
-
-`end-kbd-macro (C-x ))'
-     Stop saving the characters typed into the current keyboard macro
-     and save the definition.
-
-`call-last-kbd-macro (C-x e)'
-     Re-execute the last keyboard macro defined, by making the
-     characters in the macro appear as if typed at the keyboard.

-Some Miscellaneous Commands
----------------------------
-
-`re-read-init-file (C-x C-r)'
-     Read in the contents of the INPUTRC file, and incorporate any
-     bindings or variable assignments found there.
-
-`abort (C-g)'
-     Abort the current editing command and ring the terminal's bell
-     (subject to the setting of `bell-style').
-
-`do-uppercase-version (M-a, M-b, M-X, ...)'
-     If the metafied character X is lowercase, run the command that is
-     bound to the corresponding uppercase character.
-
-`prefix-meta (ESC)'
-     Make the next character typed be metafied.  This is for keyboards
-     without a meta key.  Typing `ESC f' is equivalent to typing `M-f'.
-
-`undo (C-_, C-x C-u)'
-     Incremental undo, separately remembered for each line.
-
-`revert-line (M-r)'
-     Undo all changes made to this line.  This is like executing the
-     `undo' command enough times to get back to the beginning.
-
-`tilde-expand (M-~)'
-     Perform tilde expansion on the current word.
-
-`set-mark (C-@)'
-     Set the mark to the current point.  If a numeric argument is
-     supplied, the mark is set to that position.
-
-`exchange-point-and-mark (C-x C-x)'
-     Swap the point with the mark.  The current cursor position is set
-     to the saved position, and the old cursor position is saved as the
-     mark.
-
-`character-search (C-])'
-     A character is read and point is moved to the next occurrence of
-     that character.  A negative count searches for previous
-     occurrences.
-
-`character-search-backward (M-C-])'
-     A character is read and point is moved to the previous occurrence
-     of that character.  A negative count searches for subsequent
-     occurrences.
-
-`insert-comment (M-#)'
-     The value of the `comment-begin' variable is inserted at the
-     beginning of the current line, and the line is accepted as if a
-     newline had been typed.
-
-`dump-functions ()'
-     Print all of the functions and their key bindings to the Readline
-     output stream.  If a numeric argument is supplied, the output is
-     formatted in such a way that it can be made part of an INPUTRC
-     file.  This command is unbound by default.
-
-`dump-variables ()'
-     Print all of the settable variables and their values to the
-     Readline output stream.  If a numeric argument is supplied, the
-     output is formatted in such a way that it can be made part of an
-     INPUTRC file.  This command is unbound by default.
-
-`dump-macros ()'
-     Print all of the Readline key sequences bound to macros and the
-     strings they ouput.  If a numeric argument is supplied, the output
-     is formatted in such a way that it can be made part of an INPUTRC
-     file.  This command is unbound by default.

-
-Readline vi Mode
-================
-
-   While the Readline library does not have a full set of `vi' editing
-functions, it does contain enough to allow simple editing of the line.
-The Readline `vi' mode behaves as specified in the POSIX 1003.2
-standard.
-
-   In order to switch interactively between `emacs' and `vi' editing
-modes, use the command M-C-j (toggle-editing-mode).  The Readline
-default is `emacs' mode.
-
-   When you enter a line in `vi' mode, you are already placed in

-# Among the more interesting lossages I noticed among Bourne shells:
-#     * No shell functions.

-.TH TEXI2HTML 1 "01/05/98"
-.AT 3
-.SH NAME
-texi2html \- a Texinfo to HTML converter
-.SH SYNOPSIS
-.B texi2html [options] file
-.PP
-.B texi2html -check [-verbose] files
-.SH DESCRIPTION
-.I Texi2html
-converts the given Texinfo file to a set of HTML files. It tries to handle
-most of the Texinfo commands. It creates hypertext links for cross-references,
-footnotes...
-.PP
-It also tries to add links from a reference to its corresponding entry in the
-bibliography (if any). It may also handle a glossary (see the
-.B \-glossary
-option).
-.PP
-.I Texi2html
-creates several files depending on the contents of the Texinfo file and on
-the chosen options (see FILES).
-.PP
-The HTML files created by
-.I texi2html
-are closer to TeX than to Info, that's why
-.I texi2html
-converts @iftex sections and not @ifinfo ones by default. You can reverse
-this with the \-expandinfo option.
-.SH OPTIONS
-.TP 12
-.B \-check
-Check the given file and give the list of all things that may be Texinfo commands.
-This may be used to check the output of
-.I texi2html
-to find the Texinfo commands that have been left in the HTML file.
-.TP
-.B \-expandinfo
-Expand @ifinfo sections, not @iftex ones.
-.TP
-.B \-glossary
-Use the section named 'Glossary' to build a list of terms and put links in the HTML
-document from each term toward its definition.
-.TP
-.B \-invisible \fIname\fP
-Use \fIname\fP to create invisible destination anchors for index links
-(you can for instance use the invisible.xbm file shipped with this program).
-This is a workaround for a known bug of many WWW browsers, including netscape.
-.TP
-.B \-I \fIdir\fP
-Look also in \fIdir\fP to find included files.
-.TP
-.B \-menu
-Show the Texinfo menus; by default they are ignored.
-.TP
-.B \-monolithic
-Output only one file, including the table of contents and footnotes.
-.TP
-.B \-number
-Number the sections.
-.TP
-.B \-split_chapter
-Split the output into several HTML files (one per main section:
-chapter, appendix...).
-.TP
-.B \-split_node
-Split the output into several HTML files (one per node).
-.TP
-.B \-usage
-Print usage instructions, listing the current available command-line options.
-.TP
-.B \-verbose
-Give a verbose output. Can be used with the
-.B \-check
-option.
-.PP
-.SH FILES
-By default
-.I texi2html
-creates the following files (foo being the name of the Texinfo file):
-.TP 16
-.B foo_toc.html
-The table of contents.
-.TP
-.B foo.html
-The document's contents.
-.TP
-.B foo_foot.html
-The footnotes (if any).
-.PP
-When used with the
-.B \-split
-option, it creates several files (one per chapter or node), named
-.B foo_n.html
-(n being the indice of the chapter or node), instead of the single
-.B foo.html
-file.
-.PP
-When used with the
-.B \-monolithic
-option, it creates only one file:
-.B foo.html
-.SH VARIABLES
-.I texi2html
-predefines the following variables: \fBhtml\fP, \fBtexi2html\fP.
-.SH ADDITIONAL COMMANDS
-.I texi2html
-implements the following non-Texinfo commands (maybe they are in Texinfo now...):
-.TP 16
-.B @ifhtml
-This indicates the start of an HTML section, this section will passed through
-without any modification.
-.TP
-.B @end ifhtml
-This indicates the end of an HTML section.
-.SH VERSION
-This is \fItexi2html\fP version 1.52, 01/05/98.
-.PP
-The latest version of \fItexi2html\fP can be found in WWW, cf. URL
-http://wwwinfo.cern.ch/dis/texi2html/
-.SH AUTHOR
-The main author is Lionel Cons, CERN IT/DIS/OSE, Lionel.Cons@cern.ch.

-passed unmodified.

-% starts with @tab. Empty columns may be produced by supplying @tab's
-% with nothing between them for as many times as empty columns are needed,
-% ie, @tab@tab@tab will produce two empty columns.
-
-% @item, @tab, @multitable or @end multitable do not need to be on their
-% own lines, but it will not hurt if they are.
-
-% Sample multitable:
-
-%   @multitable {Column 1 template} {Column 2 template} {Column 3 template}
-%   @item first col stuff @tab second col stuff @tab third col
-%   @item 
-%   first col stuff 
-%   @tab 
-%   second col stuff 
-%   @tab 
-%   third col 
-%   @item first col stuff @tab second col stuff 
-%   @tab Many paragraphs of text may be used in any column.
-%     
-%         They will wrap at the width determined by the template.
-%   @item@tab@tab This will be in third column.
-%   @end multitable
-
-% Default dimensions may be reset by user.
-% @multitableparskip is vertical space between paragraphs in table.
-% @multitableparindent is paragraph indent in table.
-% @multitablecolmargin is horizontal space to be left between columns.
-% @multitablelinespace is space to leave between table items, baseline
-%                                                            to baseline.
