gif-1.0.tgz ??

I did start on an erlang-based gif package, but didn't quite manage to get
the LZW compression to work. This is not terribly easy using pre-bit syntax
Erlang, and may not be that easy with bit syntax either... LZW uses variable
word lengths, and I got lost in all the bit shifting across the 8-bit
boundaries of binary_to_list().

I don't know if you could use the built-in lzw compression that erlang
offers nowadays (I assume you could.) If so, I think I have a nearly working
gif implementation (AFAIR, the rest was reasonably easy.) No promises
though.

I can send you what I have so far, but it may well be that there is nothing
in there you can use.
