.SH DESCRIPTION
-\fBinfocmp\fR can be used to compare a binary \fBterminfo\fR entry with other
+\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
\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
+\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
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
+\fBF\fR for boolean variables, \fB\-1\fR for integer variables, and \fBNULL\fR
for 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.
-
+.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
.SS Source Listing Options [\-I] [\-L] [\-C] [\-r]
The \fB\-I\fR, \fB\-L\fR, and \fB\-C\fR options will produce a source listing for
each terminal named.

+.PP
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
+the \fBtermcap\fR format. \fB@INFOCMP@\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:

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

-
+.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
+entries are given in. \fB@INFOCMP@\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.

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
+superfluous. \fB@INFOCMP@\fR will flag any other \fItermname use=\fR fields that
were not needed.
