A new version pre-alpha-0.03 has been released.
It is pretty complete in terms of functionality and has a lot of runit-tests, which all succeeded on my machine, at least after having fixed the bugs that they have found.
Still missing: a lot of comments, some cleanup, some searching for bugs/testing. And all should go into a gem prior for becoming alpha.
Please observe: this is still pre-alpha, so try it, but do not use it productively.

Any comments are very welcome!
