Hi,
As a supplement to my qualification task for GSoC I implemented LZW 
compressor. I think that my code is fast, universal and it can be easily used 
in other encoders. My implementation use hash table with simple hash function 
(I've used LZW prefix code and xor to calculate new hash value). So, I'm 
sending two files: one with lzw encoder (lzw.patch) and one with patch to 
tiffenc.c (tifflzw.patch). 

Best Regards,
Bartek
