I think we should still provide the ability to set the most common 
options via the command line.  I'm also fine with specifying single 
options on the command line.  I suspect though that being able to do 
-config - is more useful for management tools than building large 
strings of command line options.

Yeah, I've never liked their printf syntax.  I was interested in 
interpolation, the syntax really doesn't matter to me.  sh is probably a 
bit easier on the eyes.

Yeah, definitely.
