  36 //  If you've used another iterator type than std::string::iterator, you have to
  37 //  instantiate the new_lexer_gen<> template for this iterator type too.
  38 //  The reason is, that the library internally uses the new_lexer_gen<>
  39 //  template with a std::string::iterator.
  40 //
  41 //  This is moved into a separate compilation unit to decouple the compilation
  42 //  of the C++ lexer from the compilation of the other modules, which helps to
  43 //  reduce compilation time.
  44 //
  45 //  The template parameter(s) supplied should be identical to the first
  46 //  parameter supplied while instantiating the boost::wave::context<> template
  47 //  (see the file cpp.cpp).
