Not yet, anyway.  This file is focused on details around the monkey patch methods from the old syntax.  It's also focused on what `setup` does but `setup` is now a no-op.  The details that are in this file are inaccurate, anyway; it claims that `RSpec::Mocks.setup(self)` adds `stub`, `should_receive` to all objects, but that's done at load time now.

Given we are trying to de-emphasize the old syntax and this file is now inaccurate, I didn't think it made sense to keep.  For using rspec-mocks outside rspec, there's the standalone cuke and the test-unit one that demonstrate that usage.
