Notes

1. You might have to provide your password for sudo when administrative privileges are required 2. The script has only been tested in XUbuntu 6.06. Please, modify this page detailing your problems (and solutions) if you find any. 3. I am no shell guru, so feel free to modify the script where you feel it will make it better. But, please do not modify just for the sake of brevity. Clarity is much more important. 4. This script is practically the same as AutomatixInstallationScript, except it's applied for EasyUbuntu, not Automatix
