dbDeleteObjectFromGroup( 
d_group 
d_object 
) 
=> t / nil 

For the sake of compatibility, the parameters are also accepted in the opposite order, unless d_object is itself a group. If the group has the type deleteNever, the group will not be deleted even if the last member is deleted. If it is of type deleteFirst, the entire group will be deleted if d_object is a member of the group. If the group is of type deleteLast, it will be deleted if no other members remain after deleting d_object.
