     NAME
          ppmtogif - convert a portable pixmap into a GIF file

     SYNOPSIS
          ppmtogif [-interlace] [-sort] [-map mapfile] [-transparent
          color] [ppmfile]

     DESCRIPTION
          Reads a portable pixmap as input.  Produces a GIF file as
          output.

     OPTIONS
          -interlace
               Tells the program to produce an interlaced GIF file.

          -sort
               Produces a GIF file with a sorted color map.

          -map mapfile

               Uses the colors found in the mapfile to create the
               colormap in the GIF file, instead of the colors from
               ppmfile. The mapfile can be any ppm file; all that
               matters is the colors in it. If the colors in ppmfile
               do not match those in mapfile , they are matched to a
               "best match". A (much) better result can be obtained by
               using the following filter in advance:

               ppmquant -floyd -map mapfile

          -transparent color
               Mark the given color as transparent in the GIF file.
               The color is specified as in ppmmake(1).  Note that
               this option outputs a GIF89a format file which might
               not be understood by your software.

          All flags can be abbreviated to their shortest unique
          prefix.
