-The configuration above will create 3 services: ``my_cache_pool``, ``cache.acme``
-and ``cache.foobar``.  The ``my_cache_pool`` pool is using the filesystem adapter
-and the other two are using the :doc:`MemcachedAdapter </components/cache/adapters/memcached_adapter>`.
-The ``cache.acme`` pool is using the Memcached server on localhost and ``cache.foobar``
-is using the Memcached server at example.com.
-
-For advanced configurations it could sometimes be useful to use a pool as an adapter.
