dd�Zdd�Zdd�Zdd�Zdd�ZdS)�Cachea�Represents a data content cache made available to the module
    space of a specific :class:`.Template` object.

    .. versionadded:: 0.6
       :class:`.Cache` by itself is mostly a
       container for a :class:`.CacheImpl` object, which implements
       a fixed API to provide caching services; specific subclasses exist to
       implement different
       caching strategies.   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.

        Caching of nested defs is a blunt tool as there is no
        management of scope -- nested defs that use cache tags
        need to have names unique of all other nested defs in the
        template, else their content will be overwritten by
        each other.
