Running screenFetch on my Gentoo

It could detect many distributions, Desktop Environments, and Window Managers.

If you use Arch Linux, its already in AUR, package name is screenfetch-git; if you are not, just use git, or simply download from GitHub. Dont forget to check it with -h for more features.
