   1 # This action periodically merges base branches into staging branches.
   2 # This is done to
   3 #  * prevent conflicts or rather resolve them early
   4 #  * make all potential breakage happen on the staging branch
   5 #  * and make sure that all major rebuilds happen before the staging
   6 #    branch get’s merged back into its base branch.
