[/section Hello World! ]
[/=====================]

If all you want to do is to time a program's execution, here is a complete program (stopclock_example.cpp):

    #include <boost/chrono_io.hpp>
    #include <boost/chrono/stopwatches/reporters/stopclock.hpp>
    #include <cmath>

    int main()
    {
        boost::chrono::system_strict_stopclock _;

        for ( long i = 0; i < 10000000; ++i )
        std::sqrt( 123.456L ); // burn some time

        return 0;
    }

Output was:

    0.832 seconds
