Overview
========

See?U{the?MemCached?homepage}?for?more?about?memcached.

Usage?summary
=============

This?should?give?you?a?feel?for?how?this?module?operates::

????import?memcache
????mc?=?memcache.Client（[‘127.0.0.1:11211‘]?debug=0）

????mc.set（“some_key“?“Some?value“）
????value?=?mc.get（“some_key“）

????mc.set（“another_key“?3）
????mc.delete（“another_key“）

????mc.set（“key“?“1“）???#?note?that?the?key?used?for?incr/decr?must?be?a?string.
????mc.incr（“key“）
????mc.decr（“key“）

The?standard?way?to?use?memcache?with?a?database?is?like?this::

????key?=?derive_key（obj）
????obj?=?mc.get（key）
????if?not?obj:
????????obj?=?backend_api.get（...）
????????mc.set（obj）

????#?we?now?have?obj?and?future?passes?through?this?code
????#?will?use?the?object?from?the?cache.
