Crane is a [message queue](http://en.wikipedia.org/wiki/Message_queue)
middleware layer for [Node](http://nodejs.org).  Applications can be constructed
by using _middleware_ and defining _routes_.

This architecture has been proven effective by [Express](http://expressjs.com/),
which provides HTTP middleware.  Crane adopts this approach, repurposing it
for use with message queues, allowing workers to be built quickly and easily,
using patterns familiar to Node.js developers.

## Install

    $ npm install crane
    
## Usage

    var crane = require('crane');
    var app = crane();
    
    app.work('tasks/email', function(msg, next) {
      console.log('sending email to: ' + msg.body.to);
      msg.ack();
    });

## Adapters

Adapters are used to connect to message queues, receiving messages and
dispatching those messages to the application for processing.

The following table lists commonly used strategies:
