Mongrel Spinner and Restart tasks for CapistranoOverview
These tasks should work with the default deploy.rb file. I assume you've at least read the Capistrano manual at rubyonrails.com, also, you should get your app running on Mongrel first with manual booting and restarting before you try to automate.

Fixed some bugs.
