  'variables': {
    # When including this gypi, the following variables must be set:
    #   schema_files:
    #     An array of json or idl files that comprise the api model.
    #   impl_dir_:
    #     The root path of API implementations; also used for the
    #     output location. (N.B. Named as such to prevent gyp from
    #     expanding it as a relative path.)
    #   root_namespace:
    #     A Python string substituion pattern used to generate the C++
    #     namespace for each API. Use %(namespace)s to replace with the API
    #     namespace, like "toplevel::%(namespace)s_api".
    #   bundle_name:
    #     A string to prepend to generated bundle class names, so that multiple
    #     bundle rules can be used without conflicting.  Only used with one of
    #     the cpp-bundle generators.
    #
    # Functions and namespaces can be excluded by setting "nocompile" to true.
