-The \fBcopywin\fR routine provides a finer granularity of control over the
-\fBoverlay\fR and \fBoverwrite\fR routines. Like in the \fBprefresh\fR
-routine, a rectangle is specified in the destination window, (\fIdminrow\fR,
-\fIdmincol\fR) and (\fIdmaxrow\fR, \fIdmaxcol\fR), and the upper-left-corner
-coordinates of the source window, (\fIsminrow\fR, \fIsmincol\fR). If the
-argument \fIoverlay\fR is \fBtrue\fR, then copying is non-destructive, as in
-\fBoverlay\fR.
