$0 RELEASE_GIT_TAG [option]
RELEASE_GIT_TAG is a 'v*' or 'e*' tag for example:
  v5.0.12
  e5.0.0-beta.6

options:
  -h|--help: Print this usage.
  -b|--base: Specify the current release base branch, can be one of
             release-50
             NOTE: this option should be used when --dryrun.
  --dryrun:  Do not actually create the git tag.
  --skip-appup: Skip checking appup
                Useful when you are sure that appup is already updated'

NOTE: For 5.0 series the current working branch must be 'release-50' for opensource edition
      and 'release-e50' for enterprise edition.
