.SH DESCRIPTION
+.SS overlay, overwrite
The \fBoverlay\fR and \fBoverwrite\fR routines overlay \fIsrcwin\fR on
top of \fIdstwin\fR.
\fIscrwin\fR and \fIdstwin\fR are not required
to be the same size; only text where the two windows overlap is copied.
The difference is that \fBoverlay\fR is non-destructive
(blanks are not copied) whereas \fBoverwrite\fR is destructive.
+.SS copywin
.PP
The \fBcopywin\fR routine provides a finer granularity of control over the
\fBoverlay\fR and \fBoverwrite\fR routines.
