GNU Mailutils is a rich and powerful protocol-independent mail framework. It contains a series of useful mail libraries, clients, and servers. These are the primary mail utilities for the GNU system. The central library is capable of handling electronic mail in various mailbox formats and protocols, both local and remote. Specifically, this project contains a POP3 server, an IMAP4 server, and a Sieve mail filter. It also provides a POSIX "mailx" client and a collection of other handy tools.
spmfilter is a mail filtering framework. It attempts to be a general filtering framework for any purpose. The API enables spmfilter plugins to access messages as they are being processed by the MTA. This allows them to examine and modify message content and meta-information during the SMTP transaction. Plugins are loaded at runtime and can be processed in any sequence. The processing chain can also be altered by a single plugin, for example if the plugin has to stop further processing.
Kalisko is an application framework. Its modular architecture allows applications to easily be built from several individual components. The current development focuses on the implementation of an IRC client, though other kinds of software are possible in the future. Features (already implemented modules) include: a small core application with a simple but powerful module system that runs on Windows and Linux; a simple IRC client using GTK+ for visualization; scripting support in Python, PHP, and Lua; a Lua console; a PHP console (Linux only); a powerful serializable data structure that can be stored in memory or written to files; a cross calling interface (xcall) that allows functions to be called and defined in and from any language; and many more.
libjc is a framework for event-driven development in C. Programs that use it can perform an arbitrary number of operations simultaneously and in the background, and later wait for some or all of them to complete. The source package includes the core library along with a few objects, each of which is able to perform a set of related operations. This framework consumes significantly less memory than standard libraries, and it scales well to multiprocessor systems.
Golem Python Framework is a Python game framework for developing and learning. It can assist a student of programming by providing opportunities to write programs with interestingly visible effects, despite their simplicity. Golem provides a Web-based interface that can be used even by very early students to learn the basics of thinking with computer code by teaching a visible character on the screen to perform various tasks. Golem is based on Python, and allows a student to use all of Python's features. It attempts to hide the intimidating face that computer programming can present. Learners who are too advanced for the Web interface can use Golem as a powerful Python development framework that is effective for developing cross-platform 2D games.
OpenBricks is an enterprise-grade embedded Linux framework that provides easy creation of custom distributions for industrial embedded devices. It features a complete embedded development kit for rapid deployment on x86, ARM, PowerPC, and MIPS systems with support for industry leaders. It is meant for individuals and companies that are looking for rapid board bring-up with fine-grain embedded Linux distribution setup with complete customization. It eliminates the need to care about BSP and toolchain.
The klish is a framework for implementing Cisco-like command-line interfaces on Unix systems. It is configurable through XML files. "Klish" stands for "Kommand Line Interface SHell". The klish is a fork of clish-0.7.3. The original clish was developed by Graeme McKerrell. The klish adds some new features, but is compatible (as much as possible) with clish's XML configuration files.
