This hacky Python script prints out the Huffman tree for the first block in a gzip file.
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:
