Quark is an audio player, for geeks, by geeks. It runs in the
background with access provided via a FIFO in the filesystem. It uses
Xine-lib for playing music, and can therefore play any file format
supported by Xine.
Quark comes with a couple front-ends to make it more useful:
* charm-quark - a CLI interface
* strange-quark - a Gnome notification area interface.
