   3 img2xpm.py  -- convert several image formats to XPM
   4
   5 Usage:
   6
   7     img2xpm.py [options] image_files...
   8
   9 Options:
  10
  11     -o <dir>       The directory to place the .xpm file(s), defaults to
  12                    the current directory.
  13
  14     -m <#rrggbb>   If the original image has a mask or transparency defined
  15                    it will be used by default.  You can use this option to
  16                    override the default or provide a new mask by specifying
  17                    a colour in the image to mark as transparent.
  18
  19     -n <name>      A filename to write the .xpm data to.  Defaults to the
  20                    basename of the image file + '.xpm'  This option overrides
  21                    the -o option.
