#
# Original script is available at https://github.com/paulfantom/travis-helper/blob/master/releasing/releaser.sh
#
# 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
# - create draft of GitHub releases by using https://github.com/github/hub
#
# 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:
# - GITHUB_TOKEN variable set with GitHub token. Access level: repo.public_repo
# - docker
# - git-semver python package (pip install git-semver)
