We are launching a new tool for Beanstalk. It will allow you to deploy files to a staging and production server from your Subversion repositories. If you want to be part of the VERY small beta group, please email us with your account name. You must be ready to actively use the tool within the next week.
The tool will allow you to insert special tags in commit logs like [deploy:staging] to make the entire process effortless. Of course, you can also choose to deploy automatically or manually from the Beanstalk interface.
Btw, this will only be available for paid plans.
