 # Function: generate_type_stubs

 # Arguments:
-#   MODULE_NAME: The name of the extension module as specified in declare_mlir_python_extension.
+#   FQ_MODULE_NAME: The fully-qualified name of the extension module (used for importing in python).
 #   DEPENDS_TARGET: The dso target corresponding to the extension module
 #     (e.g., something like StandalonePythonModules.extension._standaloneDialectsNanobind.dso)
 #   MLIR_DEPENDS_TARGET: The dso target corresponding to the main/core extension module
 #     (e.g., something like StandalonePythonModules.extension._mlir.dso)
 #   OUTPUT_DIR: The root output directory to emit the type stubs into.
 # Outputs:
 #   NB_STUBGEN_CUSTOM_TARGET: The target corresponding to generation which other targets can depend on.
