What packages needed for Beryl

[Chris]

Hi guys,
I've heard a lot of people talking about running Beryl on Kunbuntu.
Has anybody  ran Compiz also that can compare both of them.  Compiz runs
decent on machine with at least Intel 865G chipset or above..but still a
bit slow...and there are compramises using it in KDE.  Like most of the
"Look and Feel" items not working to tweak the Window decorations.  I'm
assuming it's because Compiz changes the Window manager and that's why
those controls don't work.

So what packages are needed for Beryl to work...and what else to we need
to know to get this to work properly?  

Also what are your opinions are Beryl as far as usability and stability?
I heard that Compiz and Beryl are merging companies...interesting.
