# directory.

# TODO: to conform with other similar setups, this likely needs to become
# "update.sh" and be taught how to derive the latest version (e.g. 1.2.0) from
# a given release (e.g. 1.2) and assemble a .travis.yml file dynamically.
#
# See other repos (e.g. httpd, cassandra) for update.sh examples.
