Rave is definitely the future, so we're putting all of our effort into ensuring that RaveJS is as awesome as it can possibly be.
This means that all development for curl.js and cram.js has stopped. For the foreseeable future, we will continue to respond to issues on github, as well as in the #cujojs room on freenode. However, keep in mind that there will be no further development, so some issues might not be resolved fully.
We've added some info in the README, as well as some links to various RaveJS resources and a migration guide.
Watch rave to stay up to date!
