  In the faq the authors says:

  What is he trying to say here?

  Any help would be appreciated.

   I think he is saying create:
    // Ellipsis.cp
    #include "Ellispsis.hpp"
    #include "Serialize.hpp" // for extern std::map<...> theMap;

        struct add_to_map
                  theMap["Ellipsis"] = new Ellipsis();
        add_to_map foo;
   // impliment ellipsis don't use foo anyplace in this file
   // end of file

At least that is a literal translation.
