Appending to boost::filesystem::path

Question

I have a certain boost::filesystem::path in hand and I\'d like to append a string (or path) to it.

boost::filesystem::path p(\"c:\\\\dir\");
p.appen

int main() {
  boost::filesystem::path p (__FILE__);

  std::string new_filename = p.leaf() + ".foo";
  p.remove_leaf() /= new_filename;
  std::cout << p << '\n';

  return 0;
}

Tested with 1.37, but leaf and remove_leaf are also documented in 1.35. You'll need to test whether the last component of p is a filename first, if it might not be.
