Hi Adam,

The entire grasping pipeline has undergone significant rewriting in
preparation for release. We are hoping to do an 0.2 release of it at
the end of this week, complete with documentation, a stable API, etc.

In the meantime, if you wanted to be an "early adopter" and check out
the 0.1 version that would be great, as your feedback would help us
for 0.2. You can get the most up to date version using the following
.rosinstall overlay file:

https://code.ros.org/svn/wg-ros-pkg/trunk/rosinstall_files/cturtle/pr2_manipulation-cturtle-pr2all-overlay-devel.rosinstall

To use an overlay file, you would first do a normal ROS insallation
(of cturtle in this case), then use the overlay file like this:

rosinstall target_directory overlay_file_path

And be sure to prepend the target directory to your ROS_PACKAGE_PATH

To start the manipulation pipeline, use

roslaunch pr2_tabletop_manipulation_launch pr2_tabletop_manipulation.launch

There is no documentation on the wiki yet (we are writing it this
week) but the code itself is well documented. You can get an idea of
how to run it bu looking in the package pr2_pick_and_place_demos,
which contains both Python and C++ examples.

Let me know if you have any questions, we'll be glad to assist you.
