.SH DESCRIPTION
-\fB@CAPTOINFO@\fP looks in each given text
-\fIfile\fP for \fBtermcap\fP descriptions.
-For each
-one found, an equivalent \fBterminfo\fP description is written to standard
-output.
-Termcap \fBtc\fP capabilities are translated directly to terminfo
-\fBuse\fP 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\%\%term\%info\fP description to the standard

-If no \fIfile\fP is given, then the environment variable \fBTERMCAP\fP is used
-for the filename or entry.
-If \fBTERMCAP\fP is a full pathname to a file, only
-the terminal whose name is specified in the environment variable \fBTERM\fP is
-extracted from that file.
-If the environment variable \fBTERMCAP\fP is not
-set, then the file \fB\*d\fP is read.
+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.

-.SH TRANSLATIONS FROM NONSTANDARD CAPABILITIES
-Some obsolete nonstandard capabilities will automatically be translated
-into standard (SVr4/XSI Curses) terminfo capabilities by \fB@CAPTOINFO@\fP.
-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.
+The \fB\-V\fP option reports the version of \fI\%ncurses\fP associated
+with this program and exits with a successful status.
