[ODE] Geomgroups vs composite

[Anders Olofsson]

Hello all!..

I want to constuct an object that are made up of several basic ode geometry 
objects. Right now I'm using composite objects to do this.
Is this the "right way" to do this?. I've been reading in the docs about 
geomgroups but are uncertain of what it "does".. Does it completly
replace composite objects or can both work in conjunction somehow?

Or are they 2 different things that cant be compared and I've been smoking 
something? :)
