# This is configuration for standalone WebRTC bots. It is used to keep the bot
# configurations source-side instead of in the buildbot scripts. That makes it
# easy to try different configurations of GYP and GN in tryjob patches.

  # This is a map of buildbot master names -> buildbot builder names ->
  # config names (where each config name is a key in the 'configs' dict,
  # above). mb uses this dict to look up which config to use for a given bot.
  # The builders should be sorted by the order they appear in the /builders
  # page on the buildbots, *not* alphabetically.
