> Since Scala 2.10/2.11 are source compatible, we should be able to cross build
> for both versions. From what I understand there are basically three things we
> need to figure out:
> 1. Have a two versions of our dependency graph, one that uses 2.11
> dependencies and the other that uses 2.10 dependencies.
> 2. Figure out how to publish different poms for 2.10 and 2.11.
> I think (1) can be accomplished by having a scala 2.11 profile. (2) isn't
> really well supported by Maven since published pom's aren't generated
> dynamically. But we can probably script around it to make it work. I've done
> some initial sanity checks with a simple build here:
