-\fB@INFOCMP@\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.

options are not supported in SVr4 curses.
.PP
SVr4 infocmp does not distinguish between absent and cancelled capabilities.
This implementation shows those as \*(``NULL\*('',
for consistency with missing strings.
.PP
-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.

.SH BUGS
-The \fB\-F\fR option of \fB@INFOCMP@\fR(1M) should be a \fB@TOE@\fR(1M) mode.
