# This Dockerfile starts from a base ubuntu 12.04 image and installs
# a full desktop ROS hydro.
#
# It also creates a catkin workspace for a single user named YOURNAME 
# with password YOURPASSWORD.
#
# GUI applications in the container will connect to the host's X11 server
# by mounting the .X11-unix folder on the host OS. I have no idea if this 
# works on Mac if Windows.
