EasyUbuntu is an easy to use (duh!) script that gives the Ubuntu user the most commonly requested apps, codecs, and tweaks that are not found in the base distribution - all with a few clicks of your mouse.

EasyUbuntu is so easy to use in fact, that even your grandma could be playing encrypted dvds, streaming Windows Media, and sporting the latest Nvidia or Ati drivers in minutes! And yes, EasyUbuntu is GPL.

EasyUbuntu works on (X/K)ubuntu and on all the three architectures (x86, AMD64 and PPC).
