Ulthar is a generic catalog program that will allow you to keep track of all your files, may them be scattered along dozens of different CD's. I wrote it because I needed it after burning a lot of mixed-contents CD's with the files I had downloaded.
Ulthar is written in Python, using the wxPython GUI libraries. In consequence Ulthar is a platform independent program.
Currently Ulthar supports M$ Windows and Linux/GTK+ and has been tested to work correctly on these platforms.
Ulthar name was chosen honoring H. P. Lovecraft's tales. In Ulthar no man was allowed to kill a cat.
