Hi guys. I just registered here because I see, u're discussing my project so I am glad to answer to all your questions
dcb, you couldn't extract files because there was a mistake in file extension - it was correct gzip archive, not bzip2
sorry
But still most of the archivers can handle it.
What's more important - newer version v0.2 is available with better documentation. You can also take a glance at wiki pages of the project...
