// the generated msg/*.js files, which consists of lines like:
//
// Blockly.Msg["ADD_COMMENT"] = "Add Comment";
// Blockly.Msg["CLEAN_UP"] = "Clean up Blocks";

// This obviously only works if Blockly.Msg is the Msg export from the
// Blockly.Msg module - so make sure it is, but only if there is not
// yet a Blockly global variable.
