unit SetUses;

{ AFS 14 October 2K
 Functonality needed at work, so might as well do it generically
 uses clause find replace can
 - remove a unit name wherever found in a uses clause
 - insert unit names into interface and implementation uses clauses
 - relace unit(s) with a substitute unit wherever they occur
