    The GRASS Users Manual entries for p.map and p.map.new fail
    to mention the instructions "startpanel" and "endpanel".
    The user can specify which panel to begin printing, and
    which panel to end printing.  The defaults, of course, are
    the first and last panels.  Use "startpanel" and "endpanel"
    in a map script.

    Example:

       startpanel 2

    This will start output at panel 2 and continue to end.  If the
    map is only one panel wide, nothing will be output.

    Another example:

       startpanel 2
       endpanel 3

    This will output only panels two and three, if they exist.

    These worked when I tested "p.map" with "p.select preview2".  They
    might work for Srin's use of "p.select ppm".
