-Prefix can be:
-+ - Only report server to clients as alt-server, but don't use for replication
-- - Only use server for replication, but don't advertise to clients
-No prefix means server will be advertised to clients and is used for replication
+INI Format:

+All fields in a section are optional. If the "for" key is missing, the server
+will be used for replication and will be sent to clients that request a list
+of alt servers.
+The namespace key can be specified multiple times per section. If it is missing,
+the server will be used for all image names; otherwise, it will only be used
+for images which's name starts with one of the given strings.
