action.yml

name: Auto tagger
description: |
  Creates a new version (tag+branch) for a repository based on the labels "major, minor, patch" associated with the current pull-request.
  
  As a result of the tagging:
  
  1. A new tag will be created (e.g my-repo-v1.2.3) 
  2. A branch will be created, always pointing to the latest major tag (e.g. my-repo-v1)
