[comp.graphics] GIF files & LZW compression

     I need some fairly specific info on the LZW data compression used in     
GIF files.  So far, I've managed to figure out how the compression/data       
codes are stored, how their size can vary, etc., and I have no problem        
extracting codes from a file.  What I'm not so clear about is what to 
do with them next.  I know you're supposed to organize them in a table        
of some sort, and the compression codes act like indexes in the table,        
but that's about it.  Can somebody explain how to decompress these things?    
I'd prefer just a general algorithm/explanation, but code is OK too.  

                                          Thanks in advance,
