since Petr's own domain has expired, the wiki was no longer accessible. It is now back online, and has moved to github
For now, i only changed some formatting to the syntax expected by GitHubs markdown syntax, and updated some links. Other contents should be as before (which also means, that some of it is still outdated).
If you find any errors there, or things that could be improved, please let us know. I would be happy to get any help in making this better.
