It seems to me that the rfc has already provided all knowledge neccessary to implement this compression scheme, which is a variant of LZ77 with a static huffman encoding tree(?). It should be quite easy to adapt the gzip code to handle this. Together with another very similar compression protocol MPPC (M$ version of STAC), we could make one gzip module to handle all three protocols. > > Feel free to give 'em my name, although I'm no expert on copyrights. > > -- > Brian , , > > Don't _EVER_ lose your sense of humour.... > > > -lq
