+CACHE
+------
+
+All cache ttl values are in minutes. Negative ttl values indicate that a page
+type will never expire, and thus the first time a URL is accessed, the result
+will be cached indefinitely, even if the underlying git repository changes.
+Conversely, when a ttl value is zero, the cache is disabled for that
+particular page type, and the page type is never cached.
