Subject: chmod -R u+X in ruby

I want to do a recursive changemod. But the chmod in File and
FileUtils allows only, at least as far as I have seen, to set 
absolute file permission. But I want not to make all Files 
executable and also do not want the same permissions for all files,
I want to do a "relative" change of file permissions like with
chmod -R u+X example_dir
Currently I use an
system("chmod -R u+X example_dir") and I would like to know if there is
a way to do that "naturally" in ruby.

Regards,
Tammo
