Acknowledgements
Thanks to M. David Greenspon and Jeremy Roussak for their remarks about setting the speaker volume.

Allan Marcus asked for the screen depth setting functions and Simon Fraser suggested to add the Balloon Help functions.

For the restart and shutdown procedures I used some AppleEvents code published by Pete Lewis (peter.lewis@info.curtin.edu.au) for sending AppleEvents to the Finder to ask to restart or to shutdown.

Also many thanks to Cevdet Basacik for alerting me to the AppleEvents problem and testing the bug fix.
