# You need to make sure that your source PRs have a Gerrit Change ID *prior* to
# running this script
#
# Use the following instructions to set this up globally for your account:
#  mkdir -p ~/.git-templates/hooks
#  git config --global init.templatedir '~/.git-templates'
#  curl -Lo ~/.git-templates/hooks/commit-msg https://review.gerrithub.io/tools/hooks/commit-msg
#  chmod +x ~/.git-templates/hooks/commit-msg
#
#  Then run 'git init' in all of your repositories and use
#  git commit -a --amend to add a Change-Id and force push your changes back to
#  your PR
#
#
# Make sure you have a GITHUB_ACCESS_TOKEN set in your environment
#
# More information at
# https://help.github.com/articles/creating-an-access-token-for-command-line-use/
