Taking screenshots the simple way

How to take screen shots in linux?
if you are using GNOME or KDE then probably it's an applet or a "print screen" push button.
But what if you are using any other simpler WM? i use enlightenment, and i don't have the screenshot module.
i don't have internet right now to download it.

I press
Ctrl + Alt + F1
to get a console
#import -window root -display :0 screenshot.png
and voila.
pretty simple huh!
