Linphone is a Web phone with a GNOME interface. It lets you make
two-party calls over IP networks such as the Internet. It uses the IETF
protocols SIP (Session Initiation Protocol) and RTP (Realtime TransporT
Protocol) to make calls, so it should be able to communicate with other
SIP-based Web phones. With several codecs available, it can be used
with high speed connections as well as 28k modems.

A network programming library in C++. It aims to be an efficient,
secure, easy to use, and OS-independent library for network application
development.

AA-lib is a low level gfx library. AA-lib does not require a graphics
device. In fact, there is no graphical output possible. AA-lib replaces
old-fashioned output methods with a powerful ASCII art renderer.

FontForge allows editing of outline and bitmap fonts. With it, you can
create new fonts or modify old ones. It also converts font formats and
can convert among PostScript (ASCII & binary Type 1, some Type 3s, and
some Type 0s), TrueType, OpenType (Type2), and CID-keyed fonts.
