YES IT IS: very much so! In the past year I've gone through "Filetype
Frustration" so many time I started writing my own filters. While GCG
provides some filetype conversion utilities they are incomplete, as they
are geared to conversions to and from GCG format. While I do most of my
stuff with GCG and (now) programs that can read GCG (Malign), there are
times that passing something through GCG format is just another step.
The GCG programs also require a GCG liscense. While there seem to be a
number of other file conversion utilities out there, I don't think there
is an easily extensible system with a consistent interface like PBM.

Please do it. PS: It would be nice if the same basic system ran on Unix and
VMS, so that individual "format modules" could be used with either.
