LZO is a compression library which is widely used around the world. The main problem with LZO is that it is absolutely not human readable.

People have done crazy stuff to get LZO to run in their language. Usually it implies inline assembly or trying to execute data which actually contains machine code. This is sick. Whoever is responsible for this sorry situation ought to be ashamed.

So I'm going to deobfuscate LZO and provide a ISC implementation of this algorithm in Python and C. In addition, I will provide a textual description of the algorithm so that it can be easily ported to any programming language.

I expect a severe performance degradation, but I leave optimizing for speed to other people.
