The man page doesn't look that clear to me.  It says "three pass" four times,
but also says "Nth pass", so which is it, three passes or N passes?  If it's N
pass, what are the allowable values of N, other than three?  Three or more? 
One or more?  If N can be two, is there any difference between N pass with two
passes and "two pass" mode?  If there is not, then what is the point of two
pass mode?
