\fB\-V\fR
reports the version of ncurses which was used in this program, and exits.
.SS Commands
+A few commands (\fBinit\fP, \fBreset\fP and \fBlongname\fP) are
+special; they are defined by the \fB@TPUT@\fP program.
+The others are the names of \fIcapabilities\fP from the terminal database
+(see \fBterminfo\fR(5) for a list).
+Although \fBinit\fP and \fBreset\fP resemble capability names,
+\fB@TPUT@\fP uses several capabilities to perform these special functions.
.TP
\fIcapname\fR
indicates the capability from the terminal database.
.PP
Both of these appeared in 4.4BSD,
becoming the \*(lqmodern\*(rq BSD implementation of \fBtput\fP.
+.PP
+This implementation of \fBtput\fP began from a different source than
+AT&T or BSD: Ross Ridge's \fImytinfo\fP package, published on
+\fIcomp.sources.unix\fP in December 1992.
+Ridge's program made more sophisticated use of the terminal capabilities
+than the BSD program.
+Eric Raymond used the \fBtput\fP program
+(and other parts of \fImytinfo\fP) in ncurses in June 1995.
+Using the portions dealing with terminal capabilities
+almost without change,
+Raymond made improvements to the way the command-line parameters
+were handled.

This implementation of \fBtput\fP differs from AT&T \fBtput\fP in
