-// This is a script that just calls the bash script that does the main
-// processing of the action. It works like a composite action that calls
-// a single bash script.
-//
-// This was originally a trick adopted to make bash script-based actions work
-// without docker before composite actions were supported. However, due to
-// various problems with composite actions, this trick is still needed:
