pjtoppm - convert an HP !PaintJet? file to a portable pixmap
Reads an HP !PaintJet? file as input and converts it into a
portable pixmap. This was a quick hack to save some trees,
and it only handles a small subset of the paintjet commands.
In particular, it will only handle enough commands to
convert most raster image files.
