	Well... I converted FBM for the Amiga. Yes, the code-changes
were minimal, but there was a problem. FBM is a memory-hog. It politely
refuses to touch any really large image on my 1.5 meg Amiga because it
can't malloc the memory.

	When I got hold of PBMPLUS I made a brief attempt to port it.
Same problem, but worse - it wouldn't touch even small images without
bailing, for lack of memory. Both these packages, being written for
UN*X, expect virtual memory to be available, and blithely request *huge*
buffers for images. If you've got multi-megabytes of core in your Amiga,
do go for it - the code-changes really are minimal, and the packages
well worth porting. Otherwise, anybody wanna volunteer to rewrite these
to a streamed form, reading/converting/writing one scanline at a time
wherever that's feasible?

	Definitely. I use the UN*X versions a lot, and my Amiga version
of FBM when I can. These are really useful, powerful, well-written
utilities.

	You said it. I was scanning the shelves of my local Amiga dealer
recently, looking for commercial packages to do image format
conversions. I saw one. It handled only a few formats. And they were
charging *$250.00* (!!!!!) for it! I'm glad I don't remember the name of
this package, lest my comments on their pricing become slanderous.
