Well, the list isn't infinite. And under Linux there are only
two major ones existing in any great quantity unless I am mistaken.

They are Gnome and KDE. The rest.. aren't so important for detection
I would suggest.. ok - somebody stick a stake in my heart... haha

As I said before.. I'm not so keen on that.

Perphaps somebody is writing something that only works in gnome.

The true rational is slightly different. Under windows there are distinct
window manager versions. Eg XP, Vista, Windows 7, win-ce. They *do* have a
big impact on python programs and change configurations significantly.

So my rationale is simply to have the same thing under linux where
there are two major desktops, KDE and GNOME.

Maybe on the Mac there are differences to the python developer
and we shouldn't forget those also.

I'm proposing detecting less than 10 different desktops in all. And
detecting those with two lines of code each. So 20 lines of code..

About 20 lines of new code shouldn't be so hard... I would have thought.
