+.SH NAME
+\fBinfocmp\fR - compare or print out \fIterminfo\fR descriptions
+.SH SYNOPSIS
+\fBinfocmp\fR [\fB-dcnpILCuV1\fR] [\fB-v\fR \fIn\fR] [\fB-s d\fR| \fBi\fR| \fBl\fR| \fBc\fR]
+.br
+      [\fB-w\fR \fIwidth\fR] [\fB-A\fR \fIdirectory\fR] [\fB-B\fR \fIdirectory\fR] [\fItermname\fR...]
+.SH DESCRIPTION
+\fBinfocmp\fR can be used to compare a binary \fBterminfo\fR entry with other
+terminfo entries, rewrite a \fBterminfo\fR description to take advantage of the
+\fBuse=\fR terminfo field, or print out a \fBterminfo\fR description from the
+binary file (\fBterm\fR) in a variety of formats.  In all cases, the boolean
+fields will be printed first, followed by the numeric fields, followed by the
+string fields.
+..
+.SS Default Options
+If no options are specified and zero or one \fItermnames\fR are specified, the
+\fB-I\fR option will be assumed.  If more than one \fItermname\fR is specified,
+the \fB-d\fR option will be assumed.
+..
+.SS Comparison Options [-d] [-c] [-n]
+\fBinfocmp\fR compares the \fBterminfo\fR description of the first terminal
+\fItermname\fR with each of the descriptions given by the entries for the other
+terminal's \fItermnames\fR.  If a capability is defined for only one of the
+terminals, the value returned will depend on the type of the capability:
+\fBF\fR for boolean variables, \fB-1\fR for integer variables, and \fBNULL\fR
+for string variables.
+
+The \fB-d\fR option produces a list of each capability that is different
+between two entries.  This option is useful to show the difference between two
+entries, created by different people, for the same or similar terminals.
+
+The \fB-c\fR option produces a list of each capability that is common between
+two entries.  Capabilities that are not set are ignored.  This option can be
+used as a quick check to see if the \fB-u\fR option is worth using.
+
+The \fB-n\fR option produces a list of each capability that is in neither
+entry.  If no \fItermnames\fR are given, the environment variable \fBTERM\fR
+will be used for both of the \fItermnames\fR.  This can be used as a quick
+check to see if anything was left out of a description.
+..
+.SS Source Listing Options [-I] [-L] [-C] [-r]
+The \fB-I\fR, \fB-L\fR, and \fB-C\fR options will produce a source listing for
+each terminal named.
+
+.TS
+center tab(/) ;
+l l .
+\fB-I\fR/use the \fBterminfo\fR names
+\fB-L\fR/use the long C variable name listed in <\fBterm.h\fR>
+\fB-C\fR/use the \fBtermcap\fR names
+\fB-r\fR/when using \fB-C\fR, put out all capabilities in \fBtermcap\fR form
+.TE
+
+If no \fItermnames\fR are given, the environment variable \fBTERM\fR will be
+used for the terminal name.
+
+The source produced by the \fB-C\fR option may be used directly as a
+\fBtermcap\fR entry, but not all parameterized strings can be changed to
+the \fBtermcap\fR format.  \fBinfocmp\fR will attempt to convert most of the
+parameterized information, and anything not converted will be plainly marked in
+the output and commented out.  These should be edited by hand.
+
+All padding information for strings will be collected together and placed
+at the beginning of the string where \fBtermcap\fR expects it.  Mandatory
+padding (padding information with a trailing '/') will become optional.
+
+All \fBtermcap\fR variables no longer supported by \fBterminfo\fR, but which
+are derivable from other \fBterminfo\fR variables, will be output.  Not all
+\fBterminfo\fR capabilities will be translated; only those variables which were
+part of \fBtermcap\fR will normally be output.  Specifying the \fB-r\fR option
+will take off this restriction, allowing all capabilities to be output in
+\fItermcap\fR form.
+
+Note that because padding is collected to the beginning of the capability, not
+all capabilities are output.  Mandatory padding is not supported.  Because
+\fBtermcap\fR strings are not as flexible, it is not always possible to convert
+a \fBterminfo\fR string capability into an equivalent \fBtermcap\fR format.  A
+subsequent conversion of the \fBtermcap\fR file back into \fBterminfo\fR format
+will not necessarily reproduce the original \fBterminfo\fR
+source.
+
+Some common \fBterminfo\fR parameter sequences, their \fBtermcap\fR
+equivalents, and some terminal types which commonly have such sequences, are:

+.TE
+.SS Use= Option [-u]
+The \fB-u\fR option produces a \fBterminfo\fR source description of the first
+terminal \fItermname\fR which is relative to the sum of the descriptions given
+by the entries for the other terminals \fItermnames\fR.  It does this by
+analyzing the differences between the first \fItermname\fR and the other
+\fItermnames\fR and producing a description with \fBuse=\fR fields for the
+other terminals.  In this manner, it is possible to retrofit generic terminfo
+entries into a terminal's description.  Or, if two similar terminals exist, but
+were coded at different times or by different people so that each description
+is a full description, using \fBinfocmp\fR will show what can be done to change
+one description to be relative to the other.
+
+A capability will get printed with an at-sign (@) if it no longer exists in the
+first \fItermname\fR, but one of the other \fItermname\fR entries contains a
+value for it.  A capability's value gets printed if the value in the first
+\fItermname\fR is not found in any of the other \fItermname\fR entries, or if
+the first of the other \fItermname\fR entries that has this capability gives a
+different value for the capability than that in the first \fItermname\fR.
+
+The order of the other \fItermname\fR entries is significant.  Since the
+terminfo compiler \fBtic\fR does a left-to-right scan of the capabilities,
+specifying two \fBuse=\fR entries that contain differing entries for the same
+capabilities will produce different results depending on the order that the
+entries are given in.  \fBinfocmp\fR will flag any such inconsistencies between
+the other \fItermname\fR entries as they are found.
+
+Alternatively, specifying a capability \fIafter\fR a \fBuse=\fR entry that
+contains that capability will cause the second specification to be ignored.
+Using \fBinfocmp\fR to recreate a description can be a useful check to make
+sure that everything was specified correctly in the original source
+description.
+
+Another error that does not cause incorrect compiled files, but will slow down
+the compilation time, is specifying extra \fBuse=\fR fields that are
+superfluous.  \fBinfocmp\fR will flag any other \fItermname use=\fR fields that
+were not needed.
+..
+.SS Changing Databases [-A \fIdirectory\fR] [-B \fIdirectory\fR]
+The location of the compiled \fBterminfo\fR database is taken from the
+environment variable \fBTERMINFO\fR .  If the variable is not defined, or the
+terminal is not found in that location, the system \fBterminfo\fR database,
+in \fB/usr/share/terminfo\fR, will be used.  The options \fB-A\fR
+and \fB-B\fR may be used to override this location.  The \fB-A\fR option will
+set \fBTERMINFO\fR for the first \fItermname\fR and the \fB-B\fR option will
+set \fBTERMINFO\fR for the other \fItermnames\fR.  With this, it is possible to
+compare descriptions for a terminal with the same name located in two different
+databases.  This is useful for comparing descriptions for the same terminal
+created by different people.
+..
+.SS Other Options [-s d|i|l|c] [-1FTVefip] [-Rsubset] [-v \fIn\fR] [-w \fIwidth\fR]
+The \fB-s\fR option sorts the fields within each type according to the argument
+below:
+..
+.TP 5
+\fBd\fR
+leave fields in the order that they are stored in the \fIterminfo\fR database.
+.TP 5
+\fBi\fR
+sort by \fIterminfo\fR name.
+.TP 5
+\fBl\fR
+sort by the long C variable name.
+.TP 5
+\fBc\fR
+sort by the \fItermcap\fR name.
+
+If the \fB-s\fR option is not given, the fields printed out will be
+sorted alphabetically by the \fBterminfo\fR name within each type,
+except in the case of the \fB-C\fR or the \fB-L\fR options, which cause the
+sorting to be done by the \fBtermcap\fR name or the long C variable
+name, respectively.
+.TP 5
+\fB-1\fR
+causes the fields to be printed out one to a line.  Otherwise,
+the fields will be printed several to a line to a maximum width
+of 60 characters.
+.TP 5
+\fB-F\fR
+compare terminfo files.  This assumes that two following arguments are
+filenames.  The files are searched for pairwise matches between
+entries, with two entries considered to match if any of their names do.
+The report printed to standard output lists entries with no matches in
+the other file, and entries with more than one match.  For entries
+with exactly one match it includes a difference report.
+.TP 5
+\fB-R\fR\fIsubset\fR
+Restrict output to a given subset.  This option is for use with archaic
+versions of terminfo like those on SVr1, Ultrix, or HP/UX that don't support
+the full set of SVR4/XSI Curses terminfo; and outright broken ports like AIX
+that have their own extensions incompatible with SVr4/XSI.  Available terminfo
+subsets are "SVr1", "Ultrix", "HP", and "AIX"; see \fBterminfo\fR(\*n) for
+details.  You can also choose the subset "BSD" which selects only capabilities
+with termcap equivalents recognized by 4.4BSD.
+.TP 5
+\fB-T\fR
+eliminates size-restrictions on the generated text.
+This is mainly useful for testing and analysis, since the compiled
+descriptions are limited (e.g., 1023 for termcap, 4096 for terminfo).
+.TP 5
+\fB-V\fR
+prints out the version of the program in use on standard error and exits.
+.TP 5
+\fB-e\fR
+Dump the capabilities of the given terminal as a C initializer for a
+TERMTYPE structure (the terminal capability structure in the \fB<term.h>\fR).
+This option is useful for preparing versions of the curses library hardwired
+for a given terminal type.
+.TP
+\fB-f\fR
+Display complex terminfo strings which contain if/then/else/endif expressions
+indented for readability.
+.TP
+\fB-g\fR
+Display constant character literals in quoted form
+rather than their decimal equivalents.
+.TP 5
+\fB-i\fR
+Analyze the initialization (\fBis1\fR, \fBis2\fR, \fBis3\fR), and reset
+(\fBrs1\fR, \fBrs2\fR, \fBrs3\fR), strings in the entry.  For each string, the
+code tries to analyze it into actions in terms of the other capabilities in the
+entry, certain X3.64/ISO 6429/ECMA-48 capabilities, and certain DEC VT-series
+private modes (the set of recognized special sequences has been selected for
+completeness over the existing terminfo database).  Each report line consists
+of the capability name, followed by a colon and space, followed by a printable
+expansion of the capability string with sections matching recognized actions
+translated into {}-bracketed descriptions.  Here is a list of the DEC/ANSI
+special sequences recognized:
