# Used for the job that is notified when the master chef repository is updated when
# a cookbook, role, environment or data bag repository updates chef-repo. When 
# cookbook-dependency.py, cookbook-update.sh or other-buid.sh are run, they will 
# update chef-repo and push the changes, causing GitHub to trigger Jenkins to run 
# the job with this shell script as its build step.

# Update the submodules to the proper revisions
git submodule update --init --recursive
