GOSSIP USERS: gossip now has a command line mode that is triggered if you pass a parameter on the command line. On master there is only dump_event (e.g. gossip dump_event
Initially I tried to make separate binaries (dump_relays and dump_person_relays, which are still there at present). But this became very difficult since they couldn't use any of the gossip code, only the nostr-types code. Trying to move the lower-level gossip code into a library proved also very difficult. Hence the command line thing, which is working out well.
