/**
* Kestrel is a message queue written in scala by
* robey(http://github.com/robey/kestrel).It's protocol use memcached text
* protocol,so you can use any memcached clients to talk with it.But it's
* protocol implementation is not all compatible with memcached standard
* protocol,So xmemcached supply this command factory for it.
