# WHAT THIS SCRIPT DOES
# - Check the yaml from the Style Settings for errors. If there are any, the
#	 build is aborted, the errors are passed (e.g. for a notification) and the
#	 Style Settings tab is opened.
# - takes argument as commit message (uses "patch" if executed without argument)
# - adds the commit message to the changelog
# - bumps version number in css file
# - CSS is linted and minified
# - The docs are linted and checked for invalid links
# - ToC in the CSS file is updated
# - copies css from the vault (`CSS_PATH`) into this repository
# - updates download counts in badges of the .md files
# - adds a copy of the non-minified css file and the global stylelint config for documentation
# - git add, commit, pull, and push to the remote repo

# REQUIREMENTS
# - clean-css-cli
# - stylelint
# - yamllint
# - git authentication with SSH Push Access
# - this script placed somewhere in the git repository
