##Exomizer tool source code
Exomizer is a program that compresses files in a way that tries to be as efficient as possible but still allows them to be decompressed in environments where CPU speed and RAM are limited. For some popular 8-bit computers using 6502 compatible CPUs it can also generate executable files that decompress themselves in memory when run.
Forked into Github for reference, since no official source repo exists (yet)
