    for (Map.Entry<String, BlazeCommand> e : commandsByName.entrySet()) {
        BlazeCommand command = e.getValue();
        String varName = e.getKey().toUpperCase(Locale.US).replace('-', '_');
        Command annotation = command.getClass().getAnnotation(Command.class);
        if (!annotation.completion().isEmpty()) {
            outErr.printOutLn("BAZEL_COMMAND_" + varName + "_ARGUMENT=\"" + annotation.completion() + "\"");
        }
