CDCollect is a CD catalog application for gnome.
It's goal is to be able to catalog your entire CD collection allowing for searches of your CD files with a clean and simple interface. CDCollect is written in mono using monodevelop and the gtk-sharp and sqlite libraries.
It exports an easy to use interface (if you feel it does not follow the gnome hig then it's a bug).
CDCollect allows the use of plugins (external programs) to collect information for each file of a CD in your catalog.
Searches can be performed on CDs or files in the collection.
It also catalogs compressed files (using external programs such as unzip, unrar, etc).
