I'm working on getting Remarkable working with Rails 3 / Rspec 2. I
don't know how many users care about it, but I figured I'd give users
a chance to tell me. The way it looks now, it won't be backwards
compatible (primarily because Rspec2 has a lot of refactoring,
starting from changing the namespace from Spec to Rspec).
If you need Remarkable for your project, now is the time to speak up.
