// If you've used another iterator type than std::string::iterator, you have to

// The reason is, that the library internally uses the new_lexer_gen<>

// template with a std::string::iterator.
|
|
//
|
|
// This is moved into a separate compilation unit to decouple the compilation
|
|
// of the C++ lexer from the compilation of the other modules, which helps to
|
|
// reduce compilation time.
|
|
//

// The template parameter(s) supplied should be identical to the first

// parameter supplied while instantiating the boost::wave::context<> template
