# Big hack to parse _config.yml and figure out automatically what branches of
# ehcache should be checked out and to what local directories.
#
# Runs git clone commands using the provided template
#
# Usage:
#     ./run_cmd_each_javadoc_version.rb 'git clone --branch v%s --depth 1 https://bla.bla %s'
#     # tokens are branch and dir
