them.
Capabilities are commented by prefixing them with a period.

Capabilities
that are not translatable are left in the entry under their terminfo names

from terminfo format.

Due to a fixed buffer length in older termcap libraries,
It does this check only for the predefined string capabilities;
those which are defined with the \fB\-x\fP option are ignored.

terminal descriptions.

Disable smart defaults.

Suppress comments and blank lines when showing translated source.

Restrict output to a given subset.
This option is for use with archaic
versions of terminfo like those on SVr1, Ultrix, or HP-UX that do not support

Force entry resolution (so there are no remaining tc capabilities) even
when doing translation to termcap format.

version 1.3 or BSD termcap through 4.3BSD) that does not handle multiple
tc capabilities per entry.
.TP
-\fB\-s\fR
+\fB\-s\fP
Summarize the compile by showing the database location into which entries
are written, and the number of entries which are compiled.
.TP
-\fB\-T\fR
+\fB\-T\fP
eliminates size-restrictions on the generated text.
This is mainly useful for testing and analysis, since the compiled
descriptions are limited (e.g., 1023 for termcap, 4096 for terminfo).
.TP
-\fB\-t\fR
+\fB\-t\fP
tells \fB@TIC@\fP to discard commented-out capabilities.
Normally when translating from terminfo to termcap,
untranslatable capabilities are commented-out.
.TP 5
-\fB\-U\fR

Normally, it infers data which is commonly missing in older terminfo data,
