LZ derivative

[E. Kopylov]

Hello!

 I was wondering if you have source code specifically for the LZ
 algorithm used in gzip? I looked over DEFLATE but extracting the LZ
 component may be a difficult task. I'm with a research group at
 McMaster University, writing a paper on the fastest LZ algorithm used
 to date and we would love to have gzip's LZ to compare with other
 codes. Thank you very much!
