autoproj is a manager for sets of software packages. It allows the user to import and build packages from source, still using the underlying distribution's native package manager for software that is available on it.

Collection of classes to handle build systems (CMake, autotools, ...) and import mechanisms (tarballs, CVS, SVN, git, ...). It also offers a Rake integration to import and build such software packages. It is the backbone of the autoproj (http://rock-robotics.org/autoproj) integrated software project management tool.

MetaRuby is a set of module and classes that help one use the Ruby type system as a basis for modelling.

The Roby plan manager is currently developped from within the Robot Construction Kit (http://rock-robotics.org). Have a look there. Additionally, the [Roby User Guide](http://rock-robotics.org/api/tools/roby) is a good place to start with Roby.
