I'm looking to include a catkin_lint step in the travis config at ros-industrial/fanuc.

Based on my understanding of the industrial_ci readme, I'm leaning towards including a custom sh script to run after the default .ci_config/travis.sh.

Is there something like an after_script (to complement before_script)? Or is my proposed approach ok? I'm assuming a non-zero exit status of any of the commands in my custom script will cause be build to fail?
