NAME
       macptopbm - convert a MacPaint file into a portable bitmap

SYNOPSIS
       macptopbm [-extraskip N] [macpfile]

DESCRIPTION
       Reads a MacPaint file as input.  Produces a portable bitmap as output.

OPTIONS
       -extraskip
              This flag is to get around a problem with some methods of trans-
              ferring 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.

       All flags can be abbreviated to their shortest unique prefix.
