 future, so we might want to use a config file, where we put our bridges
 and annotate them with the transports they support. Possible example of
 such a config file:

 this information to every facilitator. Is there any way we can have the
 facilitator read this information from the bridge instead? From pt-
 spec.txt:

 > {{{
 >  363   Bridges use transport lines in their extra-info documents to

 >  366      transport SP <transportname> SP <address:port> [SP arglist] NL

 In the future, perhaps, the facilitator will be able to automatically pull
 relay descriptors from the consensus, so you don't have to set them up
 manually. But setting them up manually is what we should do in the short
 and maybe even long term. The facilitator doesn't need to know about every
 relay. The only reason to configure lots of relays is to deal with load--
 currently, one websocket relay is enough to handle the load. It's not like
 the case with bridges where you need a lot of them to make them hard to
 enumerate, apart from their capacity.
