...or, what is the best practise for ensuring that capistrano gets plugin code to the production server? Do you hook up your plugins to the originating repository (thereby automatically picking up changes to the plugin), or check them into your application''s repo and use "script/plugin update" to keep plugins fresh? Does that method mess with your .svn directories? thanks for
