George is a file reorganizer and CD creator, especially suited for the creation of MP3 archive CD's. It will take files from all around your system and/or network, organize them into somewhat lexicographically sorted CD-sized chunks and provide means to create CDs using external pre-mastering and mastering software. George is written in perl, using the gnome-perl and Glade-perl modules (amongst others). There is also a command-line version of George which does not need any special (non-standard) Perl modules. To actually create CDs with George, you also need recent versions of cdrecord and mkisofs.
