Someone a little while back was wondering how to view the voyager images at
pioneer.unm.edu.  Source is there to uncompress the IMQ files (cdcomp.c) but
the source does not compile on NeXT systems.  I was interested so I modified
the source to work on NeXT systems (just changed some args to fopen.) I will
place the source and a stripped executable at sonata as cdcomp.tar.Z.

I use the 'Unlabelled binary array' option (#4) in cdcomp and then put that
through 'rawtopgm' from the pbmplus utils.  The images are 800x800 so:
%rawtopgm 800 800 image.file > image.pgm
gives you a pgm file that ImageViewer can read.
