+## Versioned Deploys
+
+**Description**: Originally, this was Coleslaw's only deploy behavior.
+  Instead of deploying directly to `:deploy-dir`, creates `.curr` and
+  `.prev` symlinks in the *deploy-dir*, which point to timestamped
+  directories of the last two deploys of the site. Deploys prior to the
+  last two are automatically cleaned up.
+
+**Example**: `(versioned)`

 **NOTE**: This plugin really should be rewritten to act as a

plugins/versioned.lisp

     (when (probe-file curr)
       (update-symlink prev (truename curr)))
     (update-symlink curr new-build)))
