Liam:

I thank you for the clarification -- I was aware of the different 
names for zip.

The point I was making was that the compression technique is based 
upon Huffman encoding, which it is -- please review: 
http://www.gzip.org/algorithm.txt

I had thought so, considering that I translated it to another 
language several years ago to add functionality to an application I 
was working on at the time.

As for trying "gzip -9" on my file, I work in the Mac environment and 
commonly use Stuff-It for all my compressions -- so that option is 
unfamiliar to me.
