The page just says better deployment; but what exactly does this do?
For example, I've got a python script that uses SSH to log into my servers and manually git pull from a master repository. I imagine that this service would replace that script.
* Synchronization of changes through FTP/SFTP/S3/Rackspace Cloud Files
* Pushing your stuff to Heroku, even for SVN repos
* Release notes
* Permission management for deployments for teams
* Email notifications, atom feed for recent deployments
* Automatic deployments on pushes/commits/commit commands
* Integrations with 3rd party services, web hooks
* Simultaneous deployments to a ton of servers at once
* Almost no configuration necessary
