I could imagine that especially for the Coreutils speed might be more a 
concern than for other tools because some of the Coreutils tools are
called very often. And I would also expect that with Genparse you also get 
smaller code than with argp again because it does part of the work while
it generates the parser code while argp is a library function and so it 
does everything at run time.
