$0 RELEASE_GIT_TAG [option]
RELEASE_GIT_TAG is a 'v*' or 'e*' tag for example:
  v5.1.1
  e5.1.0-beta.6

options:
  -h|--help:         Print this usage.

  -b|--base:         Specify the current release base branch, can be one of
                     release-55
                     release-56
                     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'

  --prev-tag <tag>:  Provide the prev tag to automatically generate changelogs
                     If this option is absent, the tag found by git describe will be used


For 5.X series the current working branch must be 'release-5X'
