Note that, even though 'using namespace std' is a bad idea, 'using std::vector; using std::string' and so on is not so bad. For things that live in the base system, there's not much danger of boost conflicts. 'using namespace std' is mostly a problem when it's in headers (especially library headers), because it can break large amounts of code. In a tiny utility, it's probably the right thing to do.
