Debian package information is generally stored in files having a special file format, dubbed the Debian control file format (dctrl), a special case of the record jar file format. These tools operate on any files conforming in a general sense to that format, and are therefore widely applicable whenever this format is in play. The tools in this bundle are grep-dctrl, sort-dctrl, join-dctrl, and tbl-dctrl.

Pipo-BBS allows you to install a BBS server and clients. You can chat via a nice interface with an unlimited number of people (as with IRC). This software is in a pre-release state; it is still very alpha, and can be difficult to even compile. It works under linux, MkLinux, SGI, HP-UX, and Solaris. The only interface for this BBS is telnet for the moment; an interface using GTK has been started. It has been translated into French, English, Spanish and German.
Gnome-o-phone is an internet telephone. In other words, if you and your friend have computers with sound cards and network connections, you can use gphone to talk to each other and save on phone bills. Gphone uses GSM compression, so the data rate should be low enough to work over a reasonable modem connection. Gphone supports full duplex if your sound card does.
Gepetto provides a framework to animate characters. It lets you record choreographies and build complex moves using elementary actions. Gepetto is fully graphical and offers real-time rendering of the animation, but there is an undelying textual language describing the moves which can be used directly.
