Adding readme from readme branch into release branch

README.md

+rosjava is the first pure Java implementation of ROS.
+
+From [ROS.org](http://www.ros.org/wiki/): ROS is an open-source, meta-operating
+system for your robot. It provides the services you would expect from an
+operating system, including hardware abstraction, low-level device control,
+implementation of commonly-used functionality, message-passing between
+processes, and package management.
+
+Developed at Google in cooperation with Willow Garage, rosjava enables
+integration of Android and ROS compatible robots. This project is under active
+development and currently alpha quality software. Please report bugs and feature
+requests on the [issues
+list](https://github.com/rosjava/rosjava/issues?state=open).
+
+To get started, visit the
+[rosjava_core](http://rosjava.github.com/rosjava_core/latest) and
+[android_core](http://rosjava.github.com/android_core/latest) pages for
+documentation concerning the core libraries and examples. Also visit the roswiki
+[rosjava](http://wiki.ros.org/rosjava) and
+[android](http://wiki.ros.org/android) pages for more general rosjava-android
+information.
+
+Still have questions? Check out the ros-users [discussion
+list](https://discourse.ros.org/c/rosjava), post questions to [ROS
+Answers](http://answers.ros.org/questions/) with the tag "rosjava," or join #ROS
+on irc.oftc.net.
+
+rosjava was announced publicly during the [Cloud Robotics tech talk at Google
+I/O 2011](http://www.youtube.com/watch?feature=player_embedded&v=FxXBUp-4800).
+
+Looking for a robot platform to experiment with ROS, Android, and cloud
+robotics? The [OSRF](http://www.osrfoundation.org/)
+[TurtleBot](http://wiki.ros.org/Robots/TurtleBot) is a great mobile perception
+platform for [getting started with robotics
+development](http://www.youtube.com/watch?feature=player_embedded&v=MOEjL8JDvd0).
+
+### Branches ###
+
+The master branch reflects the latest version of rosjava. All development
+happens on the master branch in the form of pull requests from developers.
+Unless you are developing rosjava itself, you should _not_ use the master
+branch.
+
+Named branches are created whenever a new version of ROS is released. These
+branches are considered stable. No new features will be added to these branches,
+however, bug fixes may be cherry picked from master.
+
