2 # Every module that is required to build this module should have one entry.
3 # Each of the module version specifiers can take one of the following values:
4 # - A specific Git revision.
5 # - any git symbolic ref resolvable from the module's repository (e.g. "refs/heads/master" to track master branch)
6 # - an empty string to use the same branch under test (dependencies will become "refs/heads/master" if we are in the master branch)
