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).
