wrote this up very quickly last Fri as a proposal.  Forgot to add it to the 
title.  Have updated it a bit.

Pat, could you explain what you mean by the "Real Problem"? I know that we
have a lot of problems, but in terms of this release, what is the major
blocker?

Scopt is so not an issue. None whatsoever. The problem is that drivers have
unmet runtime needs that are different than libs. Scopt has absolutely
nothing to do with this. It was from a false theory that there was no 2.11
version but it actually has 2.11, 2.12, 2.09, and according to D a native
version too.

Get on to the real problems and drop this non-problem. Anything that driver
needs but is not on the classpath will stop them at runtime.

Better to say that we would be closer to release if we dropped drivers.

Supposedly. I hard coded all of the poms to Scala 2.11 (closed PR unmerged)
Pat was still having issues w sbt- but the only dependency that was on 2.10
according to maven was scopt. /shrug
