 # In this dictionary, each item stores:

 # * 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
