"""BzrDir implementation tests for bzr.

These test the conformance of all the bzrdir variations to the expected API.
Specific tests for individual formats are in the tests/test_bzrdir.py file
rather than in tests/per_branch/*.py. Generic control directory tests not
specific to BzrDir are in tests/per_controldir/*.py.
