Works only with Bitbucket at the moment.

Sample config array

var conf = [
	{
	    name: "My awesome repo", // exact repository name (Bitbucket)
	    host: 'somehost.com', // ssh host
	    user: 'ssh_user', // ssh user
	    pass: 'passw0rd', // ssh master
	    branch: 'master', // branch to watch
	    remote: 'origin', // not used atm
	    auth_login: 'login', // http auth login
	    auth_pass: 'test', // http auth password
	    url: 'http://to/git/repository', // not used atm
	    exec: [ // shell commands to execute (used to pull, move to public_html)
	        "cd git && git reset --hard HEAD",
	        "cd git && git pull origin master",
	        "cd git && cp www/* ../domain.com/public_html/"
	    ]
	},
	{
	    ...
	}
]

$ git clone -b master git@bitbucket.org:me/my-awesome-website.git .
