[comp.windows.x.motif] What is XVT?

Could someone explain to me what XVT (Extensible Virtual Toolkit) is?  I know
that it allows portability between windows, OS/2, Open Look, Motif, and Mac.
I know that it is a set of API, but how does it work.

     - Is it another layer on top of motif (or other widget toolkits?)
     - What is it like?  Is it low level like X-windows, or is it more object
       oriented like Motif widgets?
     - What is the advantages and disadvantage?

Can anyone who is actually programming in XVT describe their experience?  Thanks
