# And it defines the following variables:
#  GLIB_MARSHAL_PREFIX - The name of the files
#  GLIB_MARSHAL_LIST - File to Generate from
#  GLIB_MARSHAL_OUTPUT_HEADER - Result of Generation
#  GLIB_MARSHAL_OUTPUT_CPP - Result of Generation
#  GLIB_MARSHAL_OUTPUT_LOCATION - Where we are putting the Output
