Detecting desktop environment - KDE or Gnome?

[Erik Forsberg <forsberg+gnome-list cendio se>]

Hi!

I have a program that needs to detect which desktop environment it's
running under - KDE or Gnome.

Are there a good way to detect that you're running under Gnome? Some
Gnome-specific environment variable or similar?

Regards,
\EF
