Tzip

tzip is a file compression utility, and its associated compressed file format. It was written by Adam McKee. It uses Burrows–Wheeler transform compression. It's designed such that it could be used as a drop-in replacement for gzip (although bzip2 should be preferred over tzip).

Identification
Files begin with a two-byte ASCII signature: " ". The third byte is always  in all known versions.
