It says that the current code assumes 32-bit ints, making it a bit of
a bother to port. I also don't see what the advantages are, compared
to existing packers like pucrunch.

If all you're looking for is a compression library, I have an LZ based
library in the pipeline. It'll look and feel like my RLE Toolkit:

The new library is dubbed "backpack", as it looks backwards in the
data stream for patterns (which I believe is what LZ does - anyone
know for sure?). I haven't had time to clean it up and write docs, but
if anyone's interested I can send a copy in private email.
