.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
+\fBinfocmp\fP can be used to compare a binary \fBterminfo\fP entry with other
+terminfo entries, rewrite a \fBterminfo\fP description to take advantage of the
+\fBuse=\fP terminfo field, or print out a \fBterminfo\fP description from the
+binary file (\fBterm\fP) 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.
+If no options are specified and zero or one \fItermnames\fP are specified, the
+\fB\-I\fP option will be assumed.
+If more than one \fItermname\fP is specified,
+the \fB\-d\fP option will be assumed.
+.SS Comparison Options [\-d] [\-c] [\-n]
+\fBinfocmp\fP compares the \fBterminfo\fP description of the first terminal
+\fItermname\fP with each of the descriptions given by the entries for the other
+terminal's \fItermnames\fP.
+If a capability is defined for only one of the
+terminals, the value returned depends on the type of the capability:
+.bP
+\fBF\fP for missing boolean variables

+\fBNULL\fP for missing integer or string variables
.PP
-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.
+Use the \fB\-q\fP option to show the distinction between
+\fIabsent\fP and \fIcancelled\fP capabilities.
.PP
-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.
+These options produce a list which you can use to compare two
+or more terminal descriptions:

+Missing capabilities are ignored.

+The \fB\-u\fP option provides a related output,
+showing the first terminal description rewritten to use the second
+as a building block via the \*(``use=\*('' clause.
+.TP
+\fB\-n\fP
+produces a list of each capability that is in \fInone\fP of the given entries.
+Each item in the list shows \*(``!\*('' before the capability name.

+Normally only the conventional capabilities are shown.

+capabilities (names prefixed with \*(``OT\*('').

+If no \fItermnames\fP are given,
+\fBinfocmp\fP uses the environment variable \fBTERM\fP
+for each of the \fItermnames\fP.
+.SS Source Listing Options [\-I] [\-L] [\-C] [\-r]
+The \fB\-I\fP, \fB\-L\fP, and \fB\-C\fP options will produce

-The \fB-n\fR option produces a list of each capability that is in neither

Compiled terminal description database.
+.SH HISTORY
+Although System V Release 2 provided a terminfo library,
+it had no documented tool for decompiling the terminal descriptions.
+Tony Hansen (AT&T) wrote the first \fBinfocmp\fP in early 1984,
+for System V Release 3.
+.PP
+Eric Raymond used the AT&T documentation in 1995 to provide an equivalent
+\fBinfocmp\fP for ncurses.
+In addition, he added a few new features such as:
+.bP
+the \fB\-e\fP option, to support \fIfallback\fP
+(compiled-in) terminal descriptions
+.bP
+the \fB\-i\fP option, to help with analysis
+.PP
+Later, Thomas Dickey added the \fB\-x\fP (user-defined capabilities)
+option, and the \fB\-E\fP option to support fallback entries with
+user-defined capabilities.
+.PP
+For a complete list, see the \fIEXTENSIONS\fP section.
+.PP
+In 2010, Roy Marples provided an \fBinfocmp\fP program for NetBSD.
+It is less capable than the SVr4 or ncurses versions
+(e.g., it lacks the sorting options documented in X/Open),
+but does include the \fB\-x\fP option adapted from ncurses.
+.SH PORTABILITY
+X/Open Curses, Issue 7 (2009) provides a description of \fBinfocmp\fP.
+It does not mention the options used for converting to termcap format.
