NAME
\%@CAPTOINFO@ - convert a termcap description into a \%term\%info description
SYNOPSIS
@CAPTOINFO@ [ tic-option ] [ file .\|.\|.]

"@CAPTOINFO@ -V"

DESCRIPTION
\%@CAPTOINFO@ translates terminal descriptions. It looks in each given text file for \%termcap entries and, for each one found, writes an equivalent \%\%term\%info description to the standard output stream. \%termcap tc capabilities translate to \%\%term\%info \*(``use\*('' capabilities.

If no files are specified, \%@CAPTOINFO@ interprets the content of the environment variable \%TERMCAP as a file name, and extracts only the entry for the terminal named in the environment variable TERM from it. If the environment variable \%TERMCAP is not set, \%@CAPTOINFO@ reads \%/etc/termcap .

This utility is implemented as a link to \%@TIC@(1M), with the latter's -I option implied. You can use other \%@TIC@ options such as -1 , -f , -v , -w , and -x . The -V option reports the version of \%ncurses associated with this program and exits with a successful status.

"Translations from Nonstandard Capabilities"
\%@CAPTOINFO@ translates some obsolete, nonstandard capabilities into standard (SVr4/XSI Curses) \%\%term\%info 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.

DWB 3.3 tbl requires the two junk "L" specifiers in the first row.

XENIX \%termcap had a set of extension capabilities, corresponding to box drawing characters of CCSID (\*(``code page\*('') 437, as follows.

\f(BItermcap Name Graphic
G2 upper left corner
G3 lower left corner
G1 upper right corner
G4 lower right corner
GR tee pointing right

GU tee pointing up

\%@CAPTOINFO@ composes single-line capabilities into an acsc string, and discards GG and double-line capabilities with a warning diagnostic.

IBM's AIX has a \%\%term\%info facility descended from SVr1 \%\%term\%info, but which is incompatible with the SVr4 format. \%@CAPTOINFO@ translates the following AIX extensions.

IBM XSI
ksel kslt
kbtab kcbt
font0 s0ds
font1 s1ds
font2 s2ds
font3 s3ds

Additionally, this program translates the AIX box1 capability to an acsc string.

The HP-UX \%\%term\%info library supports two nonstandard \%\%term\%info capabilities, meml (memory lock) and memu (memory unlock). \%@CAPTOINFO@ discards these with a warning message.

FILES

/etc/termcap default \%termcap terminal capability database

PORTABILITY
X/Open Curses, Issue 7 (2009) describes tic briefly, but omits this program.

SVr4 systems provide \%captoinfo as a separate application from tic. Its -v option does not accept a trace level argument n ; repeat -v n times instead.

NetBSD does not provide this application.
