\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. In all cases, the boolean
+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,

+If more than one \fItermname\fR is specified,

.SS Comparison Options [\-d] [\-c] [\-n]
\fB@INFOCMP@\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
+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

+For best results when converting to \fBtermcap\fP format,

+\fB@INFOCMP@\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.

A capability will get printed with an at-sign (@) if it no longer exists in the
