    Recipes consist of specially-structured dictionaries, with keys for package
    name, type, commands to execute, etc. The structure is documented in the
    PackageBuilder docstring in toolchain_main.py.

 # for toolchain bug fixes or new features.  This allows tests to be enabled on
 # the toolchain buildbots/trybots before the new toolchain version is pinned

 # If you are adding a test that depends on a toolchain change, you can
