define HELP_MESSAGE

  Show the dependencies of depot content

  usage:

    $(firstword $(MAKEFILE_LIST)) <archive-path>...

  This tool operates solely on the depot content. It prints the
  result only if all dependencies are present within the depot.
  Otherwise, the missing archives are given as an error message.
