AFT (Almost Free Text) is a document preparation system. It is mostly free form, meaning that there is little intrusive markup; AFT source documents look a lot like plain old ASCII text. It has a few rules for structuring your document, more to do with formatting your text than embedding lots of commands, and it produces all types of output (HTML, XHTML, LaTeX, roll-your-own XML, etc.). All that needs to be done is to edit a rule file. You can even customize your own rule files for specialized output.

Aleph One is a 3D first-person shooter game based on the game Marathon 2 by Bungie Software. It is set in a Sci-Fi universe dominated by deviant computer AIs and features a well thought-out plot. Aleph One was originally a MacOS game, but a cross-platform version ("Aleph One/SDL") based on the Simple DirectMedia Layer (SDL) library is currently under development which runs under Unix, BeOS, and Windows.
Ansiprint is a utility for printing text files (or stdin) from remote terminals using ANSI telnet escape sequences. It was inspired by the ansiprt.c component of the University of Washington's excellent email package, PINE. However, since the author believed that ansiprt.c was released under "somewhat ridiculous terms", ansiprint has been completely re-written in C++, and includes a variety of new features.
Anteater is a log analyser for MTA logfiles (such as those produced by sendmail and postfix). The tool is written in 100% C++ and is very easy to customize. Input, output, and the analysis are modular class objects with a clear interface. Currently, there are modules for reading the syslog format of sendmail and postfix that do up to eight useful analyses and write the result in plain ASCII or HTML, to stdout or to files.
