OpenPolicy - The plan and the theorie

1. Summary

There where 2 older implementation, but I think, I now have an better soulution to solve my problems. On the way, I find a gut way so save tree-structured datas.

Ideas:

A realy small implementation (no mem, no diskspace, no cpu, should work on an 386 cpu)
Types
Library to read and write datas

2. Binary Fileformat

The binary file must be readable in 2d mode.
