support zeus to boost rails init

README.md

@@ -20,6 +20,7 @@ Lots of fun options!
 * `:timeout` waits this number of seconds when restarting the Rails server before reporting there's a problem (default `20`).
 * `:server` lets you specify the webserver engine to use (try `:server => :thin`).
 * `:pid_file` specify your pid_file, so that maybe you can run multiple instances with same rails_env (default `tmp/pids/[RAILS_ENV].pid`)
+* `:zeus` support [zeus](https://github.com/burke/zeus) to boost rails init speed.
 
 This is super-alpha, but it works for me! Only really hand-tested in Mac OS X. Feel free to fork'n'fix for other
 OSes, and to add some more real tests.
