Mp3Make is a program that automates the ripping and encoding of CD audio to mp3 files. Since the programs commonly used in linux to do this are seperate, it made sense to make a glue program to make life easier. This is supplemented by downloading a cd track list from a cddb server, and using that to name the files being created.
The Mithral Client Server Software Development Kit (part of the Cosm project) allows developers to quickly and easily write large scale client-server applications including "distributed computing" and peer-to-peer types.

Memchan is an extension library to the script language Tcl, as created by John Ousterhout. It provides two new channel types for in-memory channels and the appropriate commands for their creation. They are useful to transfer large amounts of data between procedures or interpreters, and additionally provide an easy interface to on-the-fly generation of code too. No need to set or append to a string, just do a simple puts.
