Comment (by atagar):

 Hi Tim. Is this to generate tor's hardcoded list of authorities? If so
 then seems a little odd to check for the 'Authority' flag since this means
 that your script will omit authorities when they're down.

 For what it's worth Stem has a get_authorities() which references its own
 copy of the authority list...

 https://stem.torproject.org/api/descriptor/remote.html#stem.descriptor.remote.get_authorities
 https://gitweb.torproject.org/stem.git/tree/stem/descriptor/remote.py#n823

 However, probably unhelpful due to the clear chicken-and-egg since part of
 the goal is to sync this listing with the document you generate.

 Maybe the best bet would be for your script to include a hardcoded listing
 of the authority fingerprints, then...

 * Fetch their descriptors to generate the rest of the doc (address,
 or/dirport, nickname, etc).
 * If any of the hardcoded relays isn't present in the consensus then
 error.

 This way adding/removing authorities is as simple as changing the list of
 fingerprints and rerunning your script.

 Cheers! -Damian
