MacroSystem is a powerful C++ template system designed to separate data processing from content generation. It can do recursive macro replacing, nested if-else and ifnot-else constructs, and easy importing and exporting of macro files. It has been used to create dynamic Web content, email template systems, and many kinds of preprocessing utilities.
Ecartis (fomerly known as Listar) is a mailing list management program. It has a lot of similarities to Listserv (which was one of its inspirations), but has been written from scratch to support the features and abilities that the authors felt were lacking (or hard to modify/change) in some of the other list management programs available. Its main flexibility is that it is written around a plugin layer (similar to Apache), which allows you to customize and extend the manager in ways that otherwise would be hard.
ListMate is a Zope based product that allows zope users to easily define, create and administer table structures. Use it for intranet or internet presentation of all kinds of tabular data, such as delivery services, hardware lists, ip-addresses, or contacts. It contains a complete administrative toolset.
This module implements a simple Literate Programming capability for Perl. Just as Perl's Plain Old Documentation (POD) is intended to be just powerful enough to be useful while remaining easy for the programmer, Literate Perl (LIP) is intended to bring the basic benefits of Literate Programming to Perl without radically altering the way programmers/authors work.
Lithos is an evolutionary computation system using a computationally complete stack-based representation language. The sample application evolves programs to play the game of Go. The system can be applied to other areas by plugging in a different evaluation function. ANSI C source code is provided.
