# Not necessary for users or contributors, but primarily used by the end-developer (currently: Bram van Dijk) when rolling out a new distribution of Cacatoo.
# If you have suggested changes to the documentation, issue a pull request on github.
# (rollout command: sudo bash make_bundle.sh once; git add *; git commit -a -m "Message"; git push )
