se namespace aliases, etc. For the purpose of this tutorial,
            we will be presenting unqualified names for both Spirit and <a href="../../../../../phoenix/doc/html/index.html" target="_top">Phoenix</a>.
            No worries, we will always present the full working code, so you won't
            get lost. In fact, all examples in this tutorial have a corresponding
            cpp file that QuickBook (the documentation tool we are using) imports
            in here as code snippets.
