 The \fB\-p\fR option is very similar to the \fB\-s\fR option, except
-that the output contains additional information for use by a back-end such as the
-\fBRem2PS\fR program, which creates a PostScript calendar, and various
-other back-end programs.  If \fIn\fR starts with "+", then it specifies
-a number of weeks rather than a number of months, and back-ends are expected
-to produce weekly calendars.  Note that not all back-ends support
-weekly calendars; currently, only \fBrem2pdf\fR does.  Specifying a weekly
-calendar implicitly enables the pure JSON interchange format, similar
-to \fB\-ppp\fR.
