I have implemented Huffman in Python, it is not very fast yet. Further
improvements would requires writing some parts in C and use as a
module in Python, or maybe I just didn't think enough on how to
improve the python code.

If you don't know how huffman works, you may read this:
http://gpolo.ath.cx:81/implements/huffman
I have described the improvements I have done to this "teaching
version" here: http://gpolo.ath.cx:81/texts/opc

If you don't want to read at all, you can search at pypi for "huffman"

It doesn't have all the functionalities of any normal compressor, like
compressing directories, but it could be implemented of course.

Feedback is welcome
