Hi,
how get an 'user' API for the boost.test like this:

testsuite_xyz -- --help

or even

testsuite_xyz -- --save-path=/foo

to get the user aspects. I know I can get the args by

 Â Â Â  int argc{ framework::master_test_suite().argc };
 Â Â Â  char** argv{ framework::master_test_suite().argv };

Further, at test/include/boost/test/utils/runtime/cla/parser.hpp are 
some utils used by boost.test self. Anyway, the problem rises to get the 
behaviour desribed above, simply using a global fixture with:

fixture::fixture()
{
 Â Â Â  int argc{ utf::framework::master_test_suite().argc };
 Â Â Â  char** argv{ utf::framework::master_test_suite().argv };

 Â Â Â  Â Â  for (int i = 0; i != argc; ++i) {
 Â Â Â  Â Â Â  Â Â  std::cerr << "test_observer_fixture: " << argv[i] << "\n";
 Â Â Â  Â Â  }
}

doesn't give the expected results - all the BOOST_AUTO_TEST_SUITE test 
cases are called even they depend on this arguments.

Thanks,
Olaf
