Hey, @xuwei-k.

So I definitely think the README file should suggest %%.

I also think we should try to support both your % s"scalaz-core_${scalaBinaryVersion.value}" and ticket #168's %% "harmony_cats0.9.0_scalaz7.2".

I'm thinking: only normalising if the ModuleId is %%?

Need to think about it, but I'll try to release a bug-fix for this ASAP.
