Well, here is the patch to install the "Sonic Screwdriver" option to robots.
Note that all the routines are surrounded by #ifdef's so you can easily turn
off the sonic screwdriver option by undefining the SCREWDRIVERS preprocessor
variable.
This patch can be installed easily using patch(1).
If you have any suggestions, comments, flames, or whatever, send them to:
