.SH DESCRIPTION
-\fBcaptoinfo\fR looks in \fIfile\fR for \fBtermcap\fR descriptions. For each
-one found, an equivalent \fBterminfo\fR description is written to standard
-output. Termcap \fBtc\fR capabilities are translated directly to terminfo
-\fBuse\fR capabilities.
-
-If no \fIfile\fR is given, then the environment variable \fBTERMCAP\fR is used
-for the filename or entry. If \fBTERMCAP\fR is a full pathname to a file, only
-the terminal whose name is specified in the environment variable \fBTERM\fR is
-extracted from that file. If the environment variable \fBTERMCAP\fR is not
-set, then the file \fB\*d\fR is read.

-\fB-v\fR
-print out tracing information on standard error as the program runs.

-\fB-V\fR
-print out the version of the program in use on standard error and exit.

-\fB-1\fR
-cause the fields to print out one to a line. Otherwise, the fields
-will be printed several to a line to a maximum width of 60
-characters.

-.SH TRANSLATIONS FROM NONSTANDARD CAPABILITIES
+\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\%terminfo\fP description to the standard output
+stream.
+\fI\%termcap\fP \fBtc\fP capabilities translate to \fI\%terminfo\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 \fI\%\*d\fP.
.PP
-Some obsolete nonstandard capabilities will automatically be translated
-into standard (SVr4/XSI Curses) terminfo capabilities by \fBcaptoinfo\fR.
-Whenever one of these automatic translations is done, the program
-will issue an notification to stderr, inviting the user to check that
-it has not mistakenly translated a completely unknown and random
-capability and/or syntax error.
+This utility is implemented as a link to \fB\%@TIC@\fP(1M),
+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\%terminfo\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.

.SH NOTES
-This utility is actually a link to \fItic\fR(1M), running in \fI-I\fR mode.
-You can use other \fItic\fR options such as \fB-f\fR and \fB-x\fR.
-
-The trace option isn't identical to SVr4's. Under SVr4, instead of following
-the -v with a trace level n, you repeat it n times.

+The verbose option is not identical to SVr4's.
+Under SVr4,
+instead of following the \fB\-v\fP with a trace level \fIn\fP,
+you repeat it \fIn\fP times.
+.SH PORTABILITY
+X/Open Curses,
+Issue 7 (2009) describes \fBtic\fP briefly,
+but omits this program.
+SVr4 systems provide \fB\%captoinfo\fP as a separate application from
+\fBtic\fP.
+.PP
+NetBSD does not provide this application.
