 # The following parameters are used to support the component build. They are
 # needed so that bindings which are linked with a component can use the same
 # export settings for classes. The first three are for the chromium variant, and
 # the last three are for the blink variant.
 #   export_class_attribute (optional)
 #       The attribute to add to the class declaration. e.g. "CONTENT_EXPORT"
 #   export_define (optional)
 #       A define to be added to the source_set which is needed by the export
 #       header. e.g. "CONTENT_IMPLEMENTATION=1"
