Mako includes a backend that works with the Beaker caching system. Beaker itself then supports a number of backends (i.e. file, memory, memcached, etc.) The construction of a :class:`.Cache` is part of the mechanics of a :class:`.Template`, and programmatic access to this cache is typically via the :attr:`.Template.cache` attribute.
