[wplug] {window,desktop} {environment,manager}

[Brandon Kuczenski]

What's the difference between a "window manager" and a "desktop
environment"?

Specifically, what's the difference between Gnome and Enlightenment?  i.e.
what are their different roles in the user-interface experience?  And
where does 'nautilus' fit in?

(speaking of customizing my computer to be exactly what I want, I've been
focusing on the functional aspects but still haven't done much of anything
with the appearance).

Thanks in advance,
Brandon
