The attached has already been sent to 
spirit-devel_at_[hidden]; however, it's probably more 
appropriate to this list.

Could someone on this list provide pointers on how to modify the Jamfile 
to actually run the examples (in particular, the mini_xml1.cpp) with the 
input file specified?

In:

https://spirit.svn.sourceforge.net/svnroot/spirit/trunk/Spirit2x/libs/spirit/example/qi/

there's subdirectories with, apparently, inputs files to some examples:

   mini_c
   mini_xml*

For example, mini_xml1.cpp contains:
-{--cut here--
int main(int argc, char **argv)
{
     char const* filename;
     if (argc > 1)
     {
         filename = argv[1];
     }
     else
     {
         std::cerr << "Error: No input file provided." << std::endl;
         return 1;
     }

     std::ifstream in(filename, std::ios_base::in);

     if (!in)
     {
         std::cerr << "Error: Could not open input file: "
             << filename << std::endl;
         return 1;
     }
-{--cut here--

However, the Jamfile doesn't show how to feed those input files
to the programs.  Is there some way, other than manually, to
do that?
