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(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.
captoinfo translates some obsolete, nonstandard capabilities into
standard 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 X/Open

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.
