title: Keep log of capistrano deployments
body: <p>Is there a way to keep a log (either local or stored on a remote server) of every time a deployment is done via capistrano?  It would be very useful to keep a record of what revision was running at any given time in the past.</p>
  
  <p>I know that the deployment process leaves behind the deployed files for the last 10 deployments in the releases directory, but it would be nice to keep more history and have it accessible in the form of a flat file.</p>
