//  This instantiates the correct 'new_lexer' function, which generates the 
//  C++ lexer used in this sample. You will have to instantiate the 
//  new_lexer_gen<> template with the same iterator type, as you have used for
//  instantiating the boost::wave::context<> object.
//
//  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 
//  (see the file cpp.cpp).
