First functional release, which allows for basic usage. The format is still experimental, until I got some more feedback. But I have a general good feeling. Once I implemented tha repair command to even repair corrupted files and got a feeling on how robust the file format is, the format itself will get "frozen" for version 1.0 of the specification pretty soon. Some aspects, like the LZMA algorithm used is a bit underspeced, but that I also want to work on in the near future.
