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.
-
+.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.
-
+.PP
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

If no \fItermnames\fR are given, the environment variable \fBTERM\fR will be
used for the terminal name.
-
+.PP
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.
-
+.PP
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.
-
+.PP
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.
-
+.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\fR strings are not as flexible, it is not always possible to convert
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:

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.
-
+.PP
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.
-
+.PP
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.
-
+.PP
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.
-
+.PP
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

An SGR0 designates an empty highlight sequence (equivalent to {SGR:NORMAL}).

Normally when translating from terminfo to termcap,
untranslatable capabilities are commented-out.

+\fB-U\fR
+tells \fBinfocmp\fP to not post-process the data after parsing the source file.
+This feature helps when comparing the actual contents of two source files,

The \fB-r\fR option's notion of `termcap' capabilities is System V Release 4's.
Actual BSD curses versions will have a more restricted set. To see only the
4.4BSD set, use \fB-r\fR \fB-RBSD\fR.
