     # When including this gypi, the following variables must be set:
     #   schema_files:
     #     An array of json or idl files that comprise the api model.
     #   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.
     # The default root path of API implementation sources is
     # chrome/browser/extensions/api and can be overridden by setting "impl_dir".
