Created Jun 2, 2016
This is the script I currently use on OS X to get a working "swift-dev.xctoolchain" out of a built Swift. It isn't designed to work for anyone but me, but it should be easy to adapt. I always run this after every build, and then use `TOOLCHAINS=swift-dev swift build` (etc) to use the development compiler.
