Interesting compressionn system cooking at Meta.

Hello,

Idea is to make Data description first. Which makes some sort of driving instructions for the compressor. Which is used to get better results from the compression.

Just version 0.2, so just the heads up, but was thinking that installer, and some backups etc could benefit from this. It seems that it'll improve speed and compression ratio also.
