The old versions of the keys and scopes with the hyphens are still present for backwards compatibility. However, you don't need to use those.

Yeah, I can certainly understand your frustration about finding info for the '<<=' operator. This is an unfortunate side effect of cleaning up the API. All of the old examples uses it but now the documentation doesn't explain it up front.

It sounds like your problem with examining the dependency tree might be solved by one of the 'inspect' sub commands (tree|uses|definitions). Running 'inspect tree <command>' will give you the entire dependency tree for '<command>'.

I'm not sure I understand your last point. What do you mean by 'better pure Scala API, rather than DSL'? Do you mean that the SBT API is not very good? Do you mean that the '.sbt' files are annoying to use? I'm a little confused since the DSL is a Scala API.
