questions about fd

[Hector Palacios]

I was looking at FD_SINTAX and in the paper.
And I wrote and used one simple new constraint.

Could you describe the use of the following keywords?

- forall
- trigger also...
- always
- wait_switch

Where can use l_fdv (list of fd vars) appart of c funcionts?
The forall, ok. How? (if you can, give me an example)
Any other one?

Thanks...
