parameters correctly so that both the SSL server and the
"normal" server can access the session cookie and
preferably other cookies as well.
-shorturllength: Length of URL at which URLs in a message exceeding 140
- characters will be sent to the user's chosen
- shortening service.

newuser
-------
nofollowed on profile, notice, and favorites page. Default is
'sometimes'.
+url
+---
+
+Everybody loves URL shorteners. These are some options for fine-tuning
+how and when the server shortens URLs.
+
+shortener: URL shortening service to use by default. Users can override
+ individually. 'ur1.ca' by default.
+maxlength: If an URL is strictly longer than this limit, it will be
+ shortened. Note that the URL shortener service may return an
+ URL longer than this limit. Defaults to 25. Users can
+ override. If set to 0, all URLs will be shortened.
+maxnoticelength: If a notice is strictly longer than this limit, all
+ URLs in the notice will be shortened. Users can override.
+ -1 means the text limit for notices.
+
+router
+------
+
+We use a router class for mapping URLs to code. This section controls
+how that router works.
+
+cache: whether to cache the router in memcache (or another caching
+ mechanism). Defaults to true, but may be set to false for
+ developers (who might be actively adding pages, so won't want the
+ router cached) or others who see strange behavior. You're unlikely
+ to need this unless you're a developer.
