# code is going to appear loaded at bzrlib.plugins.loggerhead.loggerhead.
# This seems like the easiest thing, because bzrlib wants the top-level plugin
# directory to be the module, but when it's used as a library people expect
# the source directory to contain a directory called loggerhead. -- mbp
