 /*~ Welcome to the gossip daemon: keeper of maps!
  *
- * This is the last "global" daemon; it has three purposes.
+ * This is the last "global" daemon; it has one main purpose: to
+ * maintain the append-only gossip_store file for other daemons and
+ * plugins to read the global network map.
  *
- * 1. To determine routes for payments when lightningd asks.
- * 2. The second purpose is to receive gossip from peers (via their
- *    per-peer daemons) and send it out to them.
- * 3. Talk to `connectd` to to answer address queries for nodes.
+ * To do this, it gets gossip messages forwarded from connectd, makes
+ * gossip queries to peers, and can ask connect out to random peers to
+ * get more gossip.
  *
  * The gossip protocol itself is fairly simple, but has some twists which
  * add complexity to this daemon.
