-Configuration
-=============
-
-The MAM protocol includes a method of changing preferences regarding
-what messages should be stored. This allows users to enable or disable
-archiving by default, and set rules for specific contacts. This module
-will log no messages by default, for privacy concerns. If you decide to
-change this, you should inform your users.
-
-``` {.lua}
-default_archive_policy = false -- other options are true or "roster";

-This controls what messages are archived if the user hasn't set a
-matching rule, or another personal default.
-
-  ------------ ------------------------------------------------------
-  `false`      Store no messages. This is the default.
-  `"roster"`   Store messages to/from contacts in the users roster.
-  `true`       Store all messages.

+Query size limits

 This is the largest number of messages that are allowed to be retrieved
-in one request.
+in one request *page*. A query that does not fit in one page will
+include a reference to the next page, letting clients page through the

+blocked while processing the request and will not be able to do anything
+else.
