TCB::mysql is a DBIx::Frame interface to the default mysql authorization database that comes with MySQL. It was written for easy tracking (though not adding!) of information from this database within the Theoretical and Computational Biophysics Group at UIUC, using the same interface as the rest of the databases used there. It provides a basic administrative interface for adding, modifying, or deleting this information. It isn't as full-featured as some of the scripts that come with the package, but it still works pretty well.
Wumi is a sendmail milter using the py-milter. It rejects mail containing certain (configurable) attachment filenames (.exe, .pif, etc.) or containing a virus (checked by calling a single-user license command line scanner) by answering the SMTP DATA step with "554 5.7.1". This way, the mail server does not have to generate senseless bounces.
EmSniff is an application that helps you to capture network packets. It differs from TCPDump in that it runs as a service instead of an application. This makes it possible to capture packets in the background. This can help applications like Wireshark to be more secure since they don't have to run with root privileges anymore. They only have to connect to the EmSniff server via libemsniff.
In Save Scummer, all the usual rough edges of roguelikes have been polished off. You no longer have to make obvious decisions like whether to open a door, climb stairs, attack an enemy, or even move down a corridor. Further, the game has been equipped with infinite undo, allowing you to retract any number of moves if you find that they were unwise. Also built in are the ability to save and restore ten different save points, so you can jump back to earlier parts of your progress. Where it gets interesting, however, is that this is the only control you have over the hapless @ exploring the dungeon.
svn-dump-fast-export converts a textual representation of a Subversion repository into input suitable for git-fast-import and similar importers. Subversion repository dumps can be generated using the 'svnadmin dump' or 'svk admin dump' command. To support incremental imports, it puts a 'git-svn-id' line at the end of each commit log message if passed an URL on the command line. Empty directories and unknown properties are silently discarded. The resulting repository will generally require further processing to put each project in its own repository and to separate the history of each branch. The 'git filter-branch --subdirectory-filter' command may be useful for this purpose.
