This script will configure Ubuntu 11.04 to run RTS2

It is primary intended for demonstration of RTS2 capabilities
for workshop about observing with the 1.5m class telescope
at AOB.

Please provide password for sudo if you will be asked for it. You
can review the script before running it from its source code.
