# #BASH library

# 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.
#
# Requirements:
# - GITHUB_TOKEN variable set with GitHub token. Access level: repo.public_repo
# - git-semver python package (pip install git-semver)
