# In this dictionary, each item stores:
# * port_name -- a fully qualified port name
# * is_debug -- whether we are using a debug build
# * move_overwritten_baselines_to -- (optional) list of platform directories that we will copy an existing
#      baseline to before pulling down a new baseline during rebaselining. This is useful
#      for bringing up a new port, for example when adding a Lion was the most recent Mac version and
#      we wanted to bring up Mountain Lion, we would want to copy an existing baseline in platform/mac
#      to platform/mac-mountainlion before updating the platform/mac entry.
# * 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.
