MoonEdit is a collaborative text editor which allows many users over the Internet to edit the same document simultaneously. Every user can modify documents at any place or time, without restriction. You can watch other people's cursor movements in real time as they make changes. Each user writes text in their own color so you can easily tell who wrote what. Also included are a few bells and whistles, such as simulating the typing sound of a keyboard (so you know when others are making changes), an in-line equation evaluator (so you don't need to open a separate window for a calculator), and even a rudimentary music sequencer.
ProjectCoordinator is a Web-based collaborative workspace for project and workgroup management. It features effective information handling, and allows you to share a common document archive and quickly create a knowledge bank for the workgroup or project. It facilitates work according to a common project plan. It allows you to access the same meeting calendar and to share project news, developments, and results. The service can be used as an ASP-service, or a license can be acquired to run the software at the customer's preferred server location.
EPOR is an extensible package organiser for Unix-like systems. It's written to trace filesystem changes (something being installed) and save this information in a simple text database (this, as any other provided feature, is customisable via the embedded Guile interpreter). Database entries contain information supplied by the command line (package name, version, etc.) and traced by filesystem changes (new directories, files, etc.). This is achieved using the "LD_PRELOAD method''.
