Part of ZiK code are currently rewritten so 0.20 serie should be able to use different user interfaces and different audio player backend.
ZiK 0.20 code is written "from scratch". Old and new features are implemented step by step.
The code can be seen at http://zik.rubyforge.org/git?p=zik.git;a=shortlog;h=refs/heads/0.20 .

At the moment there is no installation procedure.
Two ui are partially implemented: a simple cli and a gtk based gui.
