Use clipboard content in a script

[Chen Levy]

Hi people.

In KDE I can do:
  #/bin/sh
  dcop klipper klipper getClipboardContent | festival --tts
This get the current clipboard text selection and read it out loud.

I know that GNOME uses D-BUS as DCOP TNG, but I was not able to grok how to use it. I read somewhere that there is a small X utility that can output the clipboard contents to stdout but I can't remember it's name.

TIA,
Chen.
