To use memcached storage you must install the `memcache` package via npm

Once you've done that, your config section should look like:

You can also set an `expire` option to the number of seconds to expire keys in.
This behaves just like the redis expirations, but does not push expirations
forward on GETs.

Sharing code is a good thing, and it should be _really_ easy to do it.

Haste is the prettiest, easist to use pastebin ever made.

to someone and they'll see what you see.
