This could be interesting:

  http://www.boost.org/doc/libs/1_39_0/doc/html/program_options.html


While we're on the topic of boost, this is neat

 http://www.boost.org/doc/libs/1_39_0/libs/parameter/doc/html/index.html

It addresses the problem we had with attaching functions to forms - 
arguments can associated with a name. At first glance it allows

  BilinearForm a(V, V, "f", f, "h", h);

or

   BilinearForm a(V, V, "h", h, "f", f);

so the user doesn't need to worry about the order of the arguments.
