Doesn't support '>=' in top-level directory

I think this issue is already solved, right?

No, we don't support >= in npm package version strings because it gets tricky (really tricky) to do proper range matching. This also seemed like a reasonable invariant because semver versions describe the API, and it's pretty rare that all future versions of a given library retain the exact same API. As such, we allow x wildcards (i.e. bull_v0.7.x), but not full-on gt/lt ranges.

I didn't notice the second half of this issue until now though -- where it't pointed out that the README suggests you can do this. We should probably fix the README.

I've updated the README to clarify this a bit. Thanks for reporting (and sorry for the delay in response!)

PS: For cases where the interface really is the same between two versions, it's probably best to just create a copy.
