How to assign a rights profile to a role

e.g.

rights profile = "Zone Management"

role = zoneadmins

# rolemod -P +"Zone Management" zoneadmins

+"profile1,profile2" => adds profile1 & profile2

-"profile1, profile2" => removes profile1 & profile2

"profilenew1, profilenew2" => replaces current (site specific??) profiles with "profilenew1 & profilenew2"
