HappyDoc is a tool for extracting documentation from Python source code. It differs from other such applications by the fact that it uses the parse tree for a module to derive the information used in its output instead of importing the module directly. This allows the user to generate documentation for modules which need special context to be imported.
INN (InterNetNews) is an extremely flexible and configurable Usenet / netnews news server. It supports accepting articles via either NNTP connections or via UUCP, as well as serving out articles to reading clients via NNTP. It supports multiple different ways of sending outgoing articles to other hosts, as well as multiple different storage mechanisms for articles and article overview information via internal APIs. Compared to other news servers, INN is more complicated with a steeper learning curve, but is extremely flexible and configurable, comes with a large suite of supporting programs, and supports embedded filters in either Perl or Python.
mxCrypto is an extension package that provides OO-style access to the cipher algorithms and hash functions included in OpenSSL/SSLeay, a very nifty cryptographic library originally written by Eric Young and now maintained by the OpenSSL team. Its main purpose is filling in the missing parts in Andrew Kuchling's pycrypt export package with high quality implementations. Due to the ITAR export restrictions on cryptographic software, Andrew's implementations are not legally downloadable from outside the US.
mxDateTime is a Python module designed to do complex date/time handling with Python. It includes new Python extensions objects for storing and working with date and time as well as date/time parsers, access to the NIST time services and many different conversion routines to other well-known date/time standards such as ISO, ARPA, COM dates, Unix ticks, JDN, MJD, TJD and others.
PyGCS is a very stripped down MUD-like chat-server written entirely in Python. It has a single "room" and no large database to keep in memory and on disk. PyGCS has no embedded programming language. PyGCS is ideally meant to be a small multi-user real-time chat system for people who have a need to talk to more than one person at a time online. It fits somewhere in between the setup IRC uses (no walking between rooms so to speak) and the MUCK/MUSH/MOO style of server.
