Possible to filter files in addon?


I’m aware of the broccoli-file-remover build plugin and would like to apply it to (at least) one of the addons we are using in our application. In this particular case, ember-simple-auth has a number of different authentication methods that we are not using but are ending up in the resulting vendor.js. I would really like to filter out what we won’t be using, but I can’t seem to find a way to hook into the addon’s build tree to change it before it ends up in the vendor tree. Is this possible in any way? If so, can anyone point me to the way I can do this?

Thanks, Craig
