Hi,

attached is REP133, which describes the wstool command that replaces 
rosws for catkin workspaces in Groovy. It is a lot of text to justify 
the introduction, but it boils down to very little change.

Basically catkin generates it's own setup.*sh files, and does not use 
the ROS_PACKAGE_PATH anymore.
So the wstool command is a clone of rosws which does not create 
setup.*sh files anymore, and does not use "other or "setup-file" 
elements in the .rosinstall, which were required for setup.*sh and 
ROS_PACKAGE_PATH respectively.

For rosbuild workspaces, continue to use rosws.
