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