mini-huff is a mini compression implementation. It utilizes a basic form of Huffman coding, and is meant to be pretty small (the code itself and and the output it produces :P ).
I call this "compressed compression", just a little play of words for ya there.
./mini_huff.py {compress|decompress} <infile> <outfile>
Just read the code, it's "self-documenting". But if you want the easy way out, see EXPLAINED.
