        Updates the symlink to the most recently deployed version. Capistrano works \
        by putting each new release of your application in its own directory. When \
        you deploy a new version, this task's job is to update the `current' symlink \
        to point at the new version. You will rarely need to call this task \
        directly; instead, use the `deploy' task (which performs a complete \
        deploy, including `restart') or the 'update' task (which does everything \
        except `restart').
