I see no reason to remove system parameters.  I think that many parameters could 
be evaluated from the perspective of the anticipated systems being used, and 
where there is no reason to not do so, set defaults to take advantage of those 
anticipated systems.  This should get rid of much of the need for AUTOGEN.  This 
should get rid of most of the need for any tuning.

However, getting rid of the parameters would then not allow specific tuning for 
the perhaps handful of uses where such tuning might be necessary.  I'm mainly 
thinking of desired restrictions.  Just because I cannot think of any such usage 
doesn't mean it will never happen.
