    # When including this gypi, the following variables must be set:
    #   schema_files:
    #     An array of json or idl files that comprise the api model.
    #   schema_include_rules (optional):
    #     An array of paths to include when searching for referenced objects,
    #     with the namespace separated by a :.
    #     Example:
    #       [ '/foo/bar:Foo::Bar::%(namespace)s' ]
    #   cc_dir:
    #     The directory to put the generated code in.
    #   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".
    #
    # Functions and namespaces can be excluded by setting "nocompile" to true.
