GNUstep is a cross-platform, object oriented environment composed of frameworks, tools, and servers (daemons). It is very similar to the Cocoa frameworks from Apple, and tries to maintain compatibility with Cocoa wherever it is desired and possible. The frameworks provide classes for containers, distributed objects, object archiving, file management, text system, font management, image composition, WYSIWYG PostScript graphics, and more.

GPP is a general-purpose preprocessor with customizable syntax, suitable for a wide range of preprocessing tasks. Its independence from any programming language makes it much more versatile than cpp, while its syntax is lighter and more flexible than that of m4. The syntax is fully customizable, which makes it possible to process text files, HTML, or source code equally efficiently in a variety of languages.
The Noble Ape Simulation is a collection of a number of autonomous simulation components including a landscape simulation, biological simulation, weather simulation, sentient creature (Noble Ape) simulation, and a simple intelligent-agent scripting language (ApeScript). Noble Ape also contains a social simulation where the Noble Apes can be tracked in terms of social groups and also over many generations to explain social phenomenon to users looking to study this kind of interaction. It has been in development for more than a fifteen years.
The SOPE package is an extensive set of frameworks (16 frameworks, ~1500 classes) which form a complete Web application server environment. Besides the Apple WebObjects compatible appserver extended with Zope concepts, it contains a large set of reusable classes: XML processing (SAX, DOM, XML-RPC), MIME/IMAP4 processing, LDAP connectivity, RDBMS connectivity, and iCalendar parsing. The parts of the package can be used stand-alone (e.g. in Cocoa applications) and do not require the appserver parts. For MacOSX developers, the package includes SOPE:X, which contains special Xcode and Cocoa support for SOPE.
