* Use permanent bus "f"
* 002 B. Bilodeau (Jan 2001)
* New comdeck phybus.cdk
* 003 B. Dugas (Sep 2000)
* Adapt to Force-Restore and Climate mode
* 004 S. Belair and B. Bilodeau (May 2001)
* New density for fresh snow
* 005 S. Belair (Sep 2001)
* Assure coherence of WVEG
* 006 B. Dugas (Nov 2002)
* Define second WSOIL level for Force-Restore
*
*
