This functionality will be available in the iostreams library, which will debut
in 1.33. Usage will be as follows:

  #include <boost/iostreams/device/file.hpp>
  #include <boost/iostreams/filter/tee.hpp>
  #include <boost/iostreams/filtering_stream.hpp>

   using namespace boost::iostreams;

   filtering_ostream out( tee(file("log.txt")) | file("output.txt"));
   out << "this goes to log and to output\n";
