These tools are for converting between Apollo graphic file formats like gpr
and gmf and standard formats like pbm.

I'm not sure of the origin of these programs.  Some were written by Kee
Hinckley when he was still at Apollo.  They were given to me by
roque@penn01.fnal.gov (Roque Oliveira).

I compiled everything I could, but didn't test any of it.  In some cases I
had to change the source to get it to compile, in which case I saved the
original with a '-' suffix on the file name.  I didn't use the Makefiles.  I
have not included the pbm package here, which is needed to build some of
these programs.  I didn't build the rle tool, because I don't have the rle
package here.
