# This script will run an API/ABI compliance check on your working copy of
# Gazebo.  Along the way, it will install a system version of Gazebo (by
# default, the latest available).  You'll be prompted as needed for sudo access
# and to confirm the installation steps.
#
# We assume that your system is already configured to use the OSRF apt 
# repository (build.osrfoundation.org).  If you haven't done that step yet, read
# about it here:
#   http://gazebosim.org/tutorials?tut=install&cat=get_started
