For what you're trying to do, you could just read the file in as a string,
use String#sub on it and write it to file again, but here is something a
little more fun (for me to write anyway):
http://pastie.caboo.se/91056
Usage:
xconf=XConf.new "/etc/X11/xorg.conf"
xconf["Device"]["Driver"]='"fglrx"'
xconf.write #This will backup the old config to /etc/X11/xorg.conf.old
#or
xconf.write "new_config"

The new config won't contain comments.

I just quickly hacked this up, so this isn't thoroughly tested and may contain
bugs (the above example works as it should, though, I tested that much).
There's obviously some room for improvement here, but for the beginning
this seems decent enough.


HTH,
Sebastian
