As MRV calls itself a ‘Development Framework’, it must be simple to create new tools based upon it. The template project gives you a kick-start to do exactly that.
At this stage, the template project itself is still to be created, however, there is a demo project from which it will be derived one day - its called AnimIO by Martin Freitag, and allows to export and import animation of nodes.
AnimIO was initially created as MEL script, which makes it especially interesting to see it re-implemented in python, using an Object-Based design and TDD.
The interested reader may have a look at its code. After cloning the repository at https://github.com/mrv-developers/AnimIO ( git clone ), it is required to recursively initialize the submodules ( git submodule update --init --recursive ). Now you would be ready to run the tests. To sum it up:
$ git clone git://github.com/mrv-developers/AnimIO.git
$ cd animio
$ git submodule update --init --recursive
$ # Test the library
$ ext/mrv/test/bin/tmrv [<maya version>]
$ # Test the performance
$ ext/mrv/test/bin/tmrv [<maya version>] test/performance
$ # Test the user interface
$ ext/mrv/test/bin/tmrv [<maya version>] --mrv-maya test/ui
