+.SH DESCRIPTION
+\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 \fIterminal-types\fP are
+specified,
+the
+\fB\-I\fP option will be assumed.
+If more than one \fIterminal-type\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
+\fIterminal-type\fP with each of the descriptions given by the entries
+for the other terminal's \fIterminal-types\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
+.bP
+\fBNULL\fP for missing integer or string variables
+.PP
+Use the \fB\-q\fP option to show the distinction between
+\fIabsent\fP and \fIcancelled\fP capabilities.
+.PP
+These options produce a list which you can use to compare two
+or more terminal descriptions:
+.TP 5
+\fB\-d\fP
+produces a list of each capability that is \fIdifferent\fP
+between two entries.
+Each item in the list shows \*(``:\*('' after the capability name,
+followed by the capability values, separated by a comma.
+.TP
+\fB\-c\fP
+produces a list of each capability that is \fIcommon\fP between
+two or more entries.
+Missing capabilities are ignored.
+Each item in the list shows \*(``=\*('' after the capability name,
+followed by the capability value.
+.IP
+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.
+.IP
+Normally only the conventional capabilities are shown.
+Use the \fB\-x\fP option to add the BSD-compatibility
+capabilities (names prefixed with \*(``OT\*('').
+.IP
+If no \fIterminal-types\fP are given,
+\fBinfocmp\fP uses the environment variable \fITERM\fP
+for each of the \fIterminal-types\fP.
+.SS "Source Listing Options [\-I] [\-L] [\-C] [\-r]"
+The \fB\-I\fP, \fB\-L\fP, and \fB\-C\fP options will produce
+a source listing for each terminal named.
+.PP
+.TS
+center;
+Lb L.
+\-I	use \fIterminfo\fP capability codes
+\-L	use \*(``long\*('' capability names
+\-C	use \fItermcap\fP capability codes
+\-r	with \fB\-C\fP, include nonstandard capabilities
+\-K	with \fB\-C\fP, improve BSD compatibility
+.TE
+.PP
+If no \fIterminal-types\fP are given,
+the environment variable \fITERM\fP will be used for the terminal name.
+.PP
+The source produced by the \fB\-C\fP option may be used directly as a
+\fBtermcap\fP entry, but not all parameterized strings can be changed to
+the \fBtermcap\fP format.
+\fBinfocmp\fP 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.
+.PP
+For best results when converting to \fBtermcap\fP format,
+you should use both \fB\-C\fP and \fB\-r\fP.
+Normally a termcap description is limited to 1023 bytes.
+\fBinfocmp\fP trims away less essential parts to make it fit.
+If you are converting to one of the (rare) termcap implementations
+which accept an unlimited size of termcap,
+you may want to add the \fB\-T\fP option.
+More often however, you must help the termcap implementation,
+and trim excess whitespace (use the \fB\-0\fP option for that).
+.PP
+All padding information for strings will be collected together and placed
+at the beginning of the string where \fBtermcap\fP expects it.
+Mandatory
+padding (padding information with a trailing \*(``/\*('') will become optional.
+.PP
+All \fBtermcap\fP variables no longer supported by \fBterminfo\fP, but which
+are derivable from other \fBterminfo\fP variables, will be output.
+Not all
+\fBterminfo\fP capabilities will be translated; only those variables which were
+part of \fBtermcap\fP will normally be output.
+Specifying the \fB\-r\fP option
+will take off this restriction, allowing all capabilities to be output in
+\fItermcap\fP form.
+Normally you would use both the \fB\-C\fP and \fB\-r\fP options.
+The actual format used incorporates some improvements for escaped characters
+from terminfo format.
+For a stricter BSD-compatible translation, use the \fB\-K\fP option
+rather than \fB\-C\fP.
+.PP
+Note that because padding is collected to the beginning of the capability, not
+all capabilities are output.
+Mandatory padding is not supported.
+Because
+\fBtermcap\fP strings are not as flexible, it is not always possible to convert
+a \fBterminfo\fP string capability into an equivalent \fBtermcap\fP format.
+A subsequent conversion of the \fBtermcap\fP file
+back into \fBterminfo\fP format
+will not necessarily reproduce the original \fBterminfo\fP source.
+.PP
+Some common \fBterminfo\fP parameter sequences, their \fBtermcap\fP
+equivalents, and some terminal types which commonly have such sequences, are:

+.SS "Use= Option [\-u]"
+The \fB\-u\fP option produces a \fBterminfo\fP source description of the first
+terminal \fIterminal-type\fP which is relative to the sum of the
+descriptions given by the entries for the other \fIterminal-types\fP.
+It does this by
+analyzing the differences between the first \fIterminal-types\fP and the
+other \fIterminal-types\fP and producing a description with \fBuse=\fP
+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\fP
+will show what can be done to change
+one description to be relative to the other.
+.PP
+A capability will be printed with an at-sign (@) if it no longer exists in the
+first \fIterminal-type\fP,
+but one of the other \fIterminal-type\fP entries contains a value for
+it.
+A capability's value will be printed if the value in the first
+\fIterminal-type\fP is not found in any of the other \fIterminal-type\fP
+entries,
+or if the first of the other \fIterminal-type\fP entries that has this
+capability gives a different value for the capability than that in the
+first \fIterminal-type\fP.
+.PP
+The order of the other \fIterminal-type\fP entries is significant.
+Since the
+terminfo compiler \fBtic\fP does a left-to-right scan of the capabilities,
+specifying two \fBuse=\fP entries that contain differing entries for the same
+capabilities will produce different results depending on the order that the
+entries are given in.
+\fBinfocmp\fP will flag any such inconsistencies between
+the other \fIterminal-type\fP entries as they are found.
+.PP
+Alternatively, specifying a capability \fIafter\fP a \fBuse=\fP entry that
+contains that capability will cause the second specification to be ignored.
+Using \fBinfocmp\fP to recreate a description can be a useful check to make
+sure that everything was specified correctly in the original source
+description.
+.PP
+Another error that does not cause incorrect compiled files, but will slow down
+the compilation time, is specifying extra \fBuse=\fP fields that are
+superfluous.
+\fBinfocmp\fP will flag any other \fIterminal-type use=\fP fields that
+were not needed.
+.SS "Changing Databases [\-A \fIdirectory\fR] [\-B \fIdirectory\fR]"
+Like other \fI\%ncurses\fP utilities,
+\fBinfocmp\fP looks for the terminal descriptions in several places.
+You can use the \fI\%TERMINFO\fP and \fI\%TERMINFO_DIRS\fP environment
+variables to override the compiled-in default list of places to search.
+See \fBcurses\fP(3X), as well as
+the \fIFetching Compiled Descriptions\fP section in \fBterminfo\fR(5).
+.PP
+You can also use the options \fB\-A\fP
+and \fB\-B\fP to override the list of places to search
+when comparing terminal descriptions:
+.bP
+The \fB\-A\fP option sets the location for the first \fIterminal-type\fP
+.bP
+The \fB\-B\fP option sets the location for the other
+\fIterminal-types\fP.
+.PP
+Using these options, it is possible to
+compare descriptions for a terminal with the same name located in two different
+databases.
+For instance,
+you can use this feature for comparing descriptions for the same terminal
+created by different people.
+.SS "Other Options"
+.TP 5
+\fB\-0\fP
+causes the fields to be printed on one line, without wrapping.
+.TP 5
+\fB\-1\fP
+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
+\fB\-a\fP
+tells \fBinfocmp\fP to retain commented-out capabilities
+rather than discarding them.
+Capabilities are commented by prefixing them with a period.
+.TP
+\fB\-D\fP
+tells \fBinfocmp\fP to print the database locations that it knows about,
+and exit.
+.TP 5
+\fB\-E\fP
+Dump the capabilities of the given terminal as tables, needed in
+the C initializer for a
+TERMTYPE structure (the terminal capability structure in the \fB<term.h>\fP).
+This option is useful for preparing versions of the curses library hardwired
+for a given terminal type.
+The tables are all declared static, and are named according to the type
+and the name of the corresponding terminal entry.
+.sp
+Before \fI\%ncurses\fP 5.0,
+the split between the \fB\-e\fP and \fB\-E\fP options was not needed;
+but support for extended names required making the arrays of terminal
+capabilities separate from the TERMTYPE structure.
+.TP 5
+\fB\-e\fP
+Dump the capabilities of the given terminal as a C initializer for a
+TERMTYPE structure (the terminal capability structure in the \fB<term.h>\fP).
+This option is useful for preparing versions of the curses library hardwired
+for a given terminal type.
+.TP 5
+\fB\-F\fP
+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.
+Normally,
+to reduce the volume of the report, use references are
+not resolved before looking for differences, but resolution can be forced
+by also specifying \fB\-r\fP.
+.TP 5
+\fB\-f\fP
+Display complex terminfo strings which contain if/then/else/endif expressions
+indented for readability.
+.TP 5
+\fB\-G\fP
+Display constant literals in decimal form
+rather than their character equivalents.
+.TP 5
+\fB\-g\fP
+Display constant character literals in quoted form
+rather than their decimal equivalents.
+.TP 5
+\fB\-i\fP
+Analyze the initialization (\fBis1\fP, \fBis2\fP, \fBis3\fP), and reset
+(\fBrs1\fP, \fBrs2\fP, \fBrs3\fP), strings in the entry,
+as well as those used for starting/stopping cursor-positioning mode
+(\fBsmcup\fP, \fBrmcup\fP) as well as starting/stopping keymap mode
+(\fBsmkx\fP, \fBrmkx\fP).
+.IP
+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.

+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 \fI\%ncurses\fP.
+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 \fI\%ncurses\fP versions
+(e.g., it lacks the sorting options documented in X/Open),
+but does include the \fB\-x\fP option adapted from \fI\%ncurses\fP.
+.SH BUGS
+The \fB\-F\fP option of \fB\%infocmp\fP(1M) should be a
+\fB\%toe\fP(1M) mode.
