Address Book Continued is a multi-user address book Web application. It also makes use of AJAX, which means that page reloads only happen on login/logout; the rest of the operations is handled asynchronously in the background. It's well usable, even over slow connections. You can even install ABC on your desktop PC and configure it so that it doesn't require login for connections coming from the local computer.
Archery is a script to extract archives intelligently. It always extracts to a single directory or file, whether the archive was prepared that way or not, so you don't have to worry about it making a mess where you are working. It supports external extractors for .arj, .cab, .tar, .ace, .lha, .rar, .7z, and cpio formats.
Continuum is a continuous integration server. It makes sure that software always builds and works as expected. Continuous integration allows software projects to find and identify problems as soon as code is in the source control system. It currently supports building Apache Maven v1 and v2 projects.
Epsilon is a small utility package. Its dependencies make it inappropriate for inclusion in Twisted, but it performs functions that are generic enough to be used in projects that don't want to share the large footprint of Divmod's other projects. Currently, it includes a powerful date/time formatting and import/export class for exchanging date and time information between all Python's various ways to interpret objects as times or time deltas. It also includes some tools for managing concurrent asynchronous processes within Twisted.
