.SH NAME
\fB\%captoinfo\fP \-
convert a \fItermcap\fP description into a \fI\%term\%info\fP description
.SH SYNOPSIS
.B captoinfo
.RI [ tic-option ]
.RI [ file
\&.\|.\|.]
.P
.B "captoinfo \-V"
.SH DESCRIPTION
\fB\%captoinfo\fP translates terminal descriptions.
It looks in each given text \fIfile\fP for \fI\%termcap\fP entries and,
for each one found,
writes an equivalent \fI\%\%term\%info\fP description to the standard
output stream.
\fI\%termcap\fP \fBtc\fP capabilities translate to \fI\%\%term\%info\fP
\*(``\fBuse\fP\*('' capabilities.
.PP
If no \fIfile\fPs are specified,
\fB\%captoinfo\fP interprets the content of the environment variable
\fI\%TERMCAP\fP as a file name,
and extracts only the entry for the terminal named in the environment
variable \fITERM\fP from it.
If the environment variable \fI\%TERMCAP\fP is not set,
\fB\%captoinfo\fP reads
.I \%/etc/termcap.
.PP
This utility is implemented as a link to \fB\%tic\fP(1),
with the latter's
.B \-I
option implied.
You can use other \fB\%tic\fP options such as
.BR \-1 ,
.BR \-f ,
.BR \-v ,
.BR \-w ,
and
.BR \-x .
The \fB\-V\fP option reports the version of \fI\%ncurses\fP associated
with this program and exits with a successful status.
.SS "Translations from Nonstandard Capabilities"
\fB\%captoinfo\fP translates some obsolete,
nonstandard capabilities into standard
(SVr4/XSI Curses)
\fI\%\%term\%info\fP capabilities.
It issues a diagnostic to the standard error stream for each,
inviting the user to check that it has not mistakenly translated an
unknown or mistyped capability name.

\fB\%captoinfo\fP composes single-line capabilities into an \fBacsc\fP
string,
and discards \fBGG\fP and double-line capabilities with a warning
diagnostic.
.PP
IBM's AIX has a \fI\%\%term\%info\fP facility descended from SVr1
\fI\%\%term\%info\fP,
but which is incompatible with the SVr4 format.
\fB\%captoinfo\fP translates the following AIX extensions.

Additionally,
this program translates the AIX \fBbox1\fP capability to an \fBacsc\fP

The HP-UX \fI\%\%term\%info\fP library supports two nonstandard
\fI\%\%term\%info\fP capabilities,
\fBmeml\fP (memory lock) and \fBmemu\fP (memory unlock).
\fB\%captoinfo\fP discards these with a warning message.

.SH PORTABILITY
X/Open Curses,
Issue 7 (2009) describes \fBtic\fP briefly,
but omits this program.
.PP
SVr4 systems provide \fB\%captoinfo\fP as a separate application from
\fBtic\fP.
Its
.B \-v
option does not accept a trace level argument
.I n;
repeat
.B \-v
.I n
times instead.
.PP
NetBSD does not provide this application.
