-#   with_environment (optional)
-#       Set to |false| to omit an implicit bindings dependency on the Chromium
-#       Mojo environment implementation. Defaults to |true| and in general

 #   typemap_deps (optional)
 #       A list of public dependencies needed to support active typemaps.
 #
 #   variant (optional)
 #       A variant name to apply to generated bindings. Variant influences
 #       generated source filenames as wells the symbols they define.
