Contains scripts for generating Boost Python bindings for ROS (www.ros.org) message types.  Uses the roslib libraries for parsing the ROS message IDL.  It does two things:
* Defines code generation and CMake macros for exporting any ROS package's roscpp message definitions into Boost Python.  For each ROS package, these produce:
  * Boost Python wrappers of the autogenerated C++ message classes
  * Functions to convert between the Boost Python wrapped classes and the existing autogenerated ROS python message classes.
* Calls those macros for a few specific ROS packages: std_msgs, geometry_msgs, sensor_msgs, nav_msgs.

Example usage of the exported messages from Python (note rosh is basically an Ipython shell with ROS-related helper functions):

$ rosh
