 #
 #   output_name (optiona)
 #       Provide an alternate base name for the generated files, like the .d
 #       files. Normally these are based on the target name and go in the
 #       output_dir, but if multiple targets with the same name end up in
 #       the same output_dir, they can collide.
 #
 #   use_qualified_include (optional)
 #       If set, output_dir is not added to include_dirs.

+#   configs (optional)
+#       List of additional configs to be applied to the generated target.
 #   deps  (optional)
 #   inputs  (optional)
 #       List of additional files, required for grit to process source file.
 #   visibility  (optional)
 #       Normal meaning.
