+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

+Eric Raymond used the \fBtput\fP program

+Using the portions dealing with terminal capabilities
