captoinfo - convert a termcap description
into a terminfo description
captoinfo [tic-option] [file
. . .]
captoinfo -V
captoinfo translates terminal descriptions. It looks
in each given text file for termcap entries and, for
each one found, writes an equivalent terminfo description to
the standard output stream. termcap tc
capabilities translate to terminfo 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(1),
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.
captoinfo translates some obsolete, nonstandard
capabilities into standard (SVr4/XSI Curses) terminfo
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.

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

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 terminfo facility descended from SVr1
terminfo, 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 terminfo library supports two nonstandard
terminfo capabilities, meml (memory lock) and
memu (memory unlock). captoinfo
discards these with a warning message.

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.
