-# In this dictionary, each item stores:
-# * port_name -- a fully qualified port name
-# * rebaseline_override_dir -- (optional) directory to put baselines in instead of where you would normally put them.
-#      This is useful when we don't have bots that cover particular configurations; so, e.g., you might
-#      support mac-mountainlion but not have a mac-mountainlion bot yet, so you'd want to put the mac-lion
-#      results into platform/mac temporarily.
-# * specifiers -- TestExpectation specifiers for that config. Valid values are found in
-#      TestExpectationsParser._configuration_tokens_list
