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.
Ftwalk is a high level script programming language, very similar to awk, but greatly extended to include a richer type system, object-oriented features, 300+ built-in functions, extensibility through dynamic libraries, etc., which makes it roughly comparable to languages like Perl. It does file tree searches, and was originally used to implement selective redundant copy backup stores. It can be run interactively as a calculator.
fistgen is the FiST language code generator, used to create stackable file systems out of templates and a high-level language. This package comes with stackable file system templates for Linux, Solaris, and FreeBSD. It also contains several sample file systems built using the FiST language: an encryption file system, a compression file system, and more - all of which are written as portable stackable file systems.
