Rippix is a fork of ripperX, a fast and easy to use CD ripper. While ripperX does a good job of ripping and encoding songs from a CD, it uses a rather outdated user interface. Rippix tries to fill this gap. This includes porting Rippix to GTK+ 3. Additionally, a lot of deprecated code will be rewritten and documentation will be added. The reason for a fork is that after some hacking on the ripperX code, it appeared that more modifications were necessary in order to port to GTK+ 3 conveniently than what could be appreciable by ripperX devs, like removing all the XPM images (including the logo) from the UI.
