Like Mac OS X, Ubuntu includes by default a privilege escalation system that invokes sudo, which allows certain users (in the admin group) to operate as limited-privileged users for almost all tasks and to temporarily escalate (after a password authentication) to administrative privileges for specific tasks. For more details about sudo, check out the Ubuntu Wiki page on the subject.
Sometimes users want to modify system files and thus need “root” (or full administrative) privileges to make changes to those files. This tutorial will show you how to create an application launcher to “browse as root.”
The rest of the fields and the icon can be whatever you want them to be.
