# See the following addresses to change this to be web driven, will need the ability to commit
# a change to the version.rb and insert version heading into the changelog.
# Also see https://riggaroo.dev/using-github-actions-to-automate-our-release-process/
# Also see https://github.com/actions/create-release

# When "rake release" is run a tag of the form 'v[0-9]*.[0.9]*.*' is pushed to the repo.
# When that tag is pushed it causes this action to run, which:
#   * Ensures the gem's version (via version.rb) matches the pushed tag before doing anything.
#   * Builds the gem.
#   * Creates a draft release in GitHub with:
#      * The built gem attached.
#      * The relevant lines from the changelog in the description.
#      * Named the same as the tag.
#   * Publishes the gem to GitHub Package Registry.
