I've briefly scanned wikipedia's pages on Huffman coding, DEFLATE,
LZ77 and LZ78, LZW, etc, and that's definitely what I'm looking for.
Wikipedia's entry on "Dictionary coder" even contains interesting
example algorithms. I can sense a fascinating project coming on...
Thank you for the pointers, Jaime
