Hi railers, What do you do when you must use a plugin in a rails app that is under subversion? I think that an approach is simply install a version of the plugin, and once all the test pass, commit the plugin itself to the repository, inside the /vendor/ of the app. If a new version of the plugin is released, your app is still using the working one (although the new version could work too).
