huffman fun

This hacky Python script prints out the Huffman tree for the first block in a gzip file. it may or may not work, no guarantees.

It uses a program called infgen available from http://zlib.net/infgen.c.gz. The Makefile here will download and compile it for you, though!

To try this out on the included gzip file, run

$ make
$ ./infgen raven.txt.gz | python print_huffman_table.py

You should see output like this:
