# These gems are only listed here in the Gemfile because we want to pin them
# to the github repositories for as long as no stable version has been released.
# The dm-core gem is a hard dependency for dm-rails so it would get pulled in by
# simply adding dm-rails. The dm-do-adapter gem is a hard dependency for any of
# the available dm-xxx-adapters. Once we have stable gems available, pinning these
# gems to github will be optional.
