README out of date?

[SpyMachine]

I've been trying to figure out how to use this gem but it doesn't seem like the README is accurate anymore. The most obvious being there is no "All" task, it is now TaskSets::All.

However, if I just update that it doesn't seem to do anything. I tried reading through the code which I'm only semi-grasping so it seems like what I want is maybe RakeDependencies::TaskSets::All.define. This seems to work, however, it seems like the "namespace" option now no longer works. I seem to be able to workaround this by just manually wrapping the whole thing in a namespace. Am I even using this correctly?
