The X Binary Package System (in short XBPS) is a binary package system designed and implemented from scratch. Its goal is to be fast, easy to use, bug-free, featureful, and portable as much as possible. There is a well documented API provided by the XBPS Library that is the basis for its frontends, to handle binary packages and repositories.
Andrew's Game aims to be a lightweight and highly expandable code base editable by anyone with a basic understanding of Python. The project has three parts: core systems, sample game, and reusable extensions. Core systems deal with the actual game mechanics; a sample game will be a template of how to use core systems and reusable extensions to create a working game. The reusable extensions can contain items and minor added functionality. Andrew's Game can implement a text-only single player RPG, which is like a MUD without support for multiple players.
libKISSlog is a trivial lightweight C++ template library designed and written according to the KISS (Keep It Simple and Straightforward) principle. It leans heavily on STL for keeping its implementation as simple as its usage, and tries to provide C++ developers with a lightweight, paradigm-pure, and flexible alternative to logging libraries which use design and/or implementation decisions which at least the author of libKISSlog believes to be questionable. Its easiest to explain why libKISSlog would be suitable for your needs by listing the things which libKISSlog does not choose to use or do: no singletons or other forms of mutable global state, no macros, no attempt to fit the Java runtime everything model onto a C++ library, no attempt to be a Java-style (bloated) framework, no attempt to make the choice for you of whether you need thread safety, and no compromise on simplicity in order to facilitate questionable inner-loop logging practices.
ecca-proxy is a Web proxy server that transparently handles Eccentric Authentication key and certificate management. Eccentric Authentication is a protocol designed to make using client certificates easy, secure, and private. The proxy handles the difficult cryptographic details and provides an easy to use interface to the user.
libquickmail is a library intended to give C/C++ developers a quick and easy way to send email from their applications. It supports multiple To/Cc/Bcc recipients and multiple MIME attachments without size limitation. It uses libcurl for SMTP communication, but a light version is also included without the libcurl dependancy. The library can also be used to just create a multipart MIME message body. It also comes with a command line application for sending mail (with optional attachments).
