Compressor benchmark

This is a tiny benchmark program I wrote a couple years ago for my personal use. It generates a few data files and feeds them to different compression libraries to measure compression ratio and speed.

Data files generated:

• bench1.dat — binary, long running lengths
• bench2.dat — text, generated using Markov chains
• bench3.dat — random uncompressible data
