       macptopbm - convert a MacPaint file into a PBM image

       In  addition  to  the options common to all programs based on libnetpbm (most notably -quiet, see  Common
       Options ), macptopbm recognizes the following command line option:

       You can abbreviate any option to its shortest unique prefix.

       -extraskip
              This option is to get around a problem with some methods of transferring files from the Mac  world
              to  the  Unix  world.   Most of these methods leave the Mac files alone, but a few of them add the
              "finderinfo" data onto the front of the Unix file.  This means an extra 128  bytes  to  skip  over
              when  reading  the file.  The symptom to watch for is that the resulting PBM file looks shifted to
              one side.  If you get this, try -extraskip 128, and if that still doesn't look right  try  another
              value.
