# Update script that tries to pull the training VM to the appropriate latest versions

# Improved robustness:
# - tries the first command line arg or "." as location for the collection
# - remaining command line args are passed through to ansible-playbook call

# - runs 'git pull --recurse-submodules' on the collection
# - runs ansible
