Liquidsoap is a powerful tool for building complex audio streaming systems, typically targetting Internet radio stations. It consists of a simple script language, which has a first-class notion of source (basically a stream) and provides elementary source constructors and source compositions from which you can build the streamer you want. There is no constraint on the streams, in contrast to many other tools which can only stream one file after another. Moreover, it is not restricted to a single stream. Finally, it interfaces well with external tools.

Kom stands for "Keep old mails". It imports email messages into a MySQL database, and provides a frontend in GTK 2 to search and browse the archived messages. Some options can be used to incrementally import email (per month, for example). It can also export messages stored in the database, in mbox format or one-message-per-file format, and generate some statistics.
