+# Script to automatically do a couple of things:
+#   - generate a new tag according to semver (https://semver.org/)
+#   - generate CHANGELOG.md by using https://github.com/skywinder/github-changelog-generator
+#   - sync CHANGELOG with GitHub releases by using https://github.com/mattbrictson/chandler
+#
+# Tags are generated by searching for a keyword in last commit message. Keywords are:
+#  - [patch] or [fix] to bump patch number
+#  - [minor], [feature] or [feat] to bump minor number
+#  - [major] or [breaking change] to bump major number
+# All keywords MUST be surrounded with square braces.
+#
+# Script uses git mechanisms for locking, so it can be used in parallel builds
+#
+# Requirements:
+#   - GH_TOKEN variable set with GitHub token. Access level: repo.public_repo
+#   - docker
+#   - git-semver python package (pip install git-semver)
+
+# Exit when latest commit is tagged
+[[ $(git tag --points-at) ]] && exit 0
