33*9712c20fSFrederick Mayle // using_std_string.h: Allows building this code in environments where
34*9712c20fSFrederick Mayle //                     global string (::string) exists.
35*9712c20fSFrederick Mayle //
36*9712c20fSFrederick Mayle // The problem:
37*9712c20fSFrederick Mayle // -------------
38*9712c20fSFrederick Mayle // Let's say you want to build this code in an environment where a global
39*9712c20fSFrederick Mayle // string type is defined (i.e. ::string).  Now, let's suppose that ::string
40*9712c20fSFrederick Mayle // is different that std::string and you'd like to have the option to easily
41*9712c20fSFrederick Mayle // choose between the two string types.  Ideally you'd like to control which
42*9712c20fSFrederick Mayle // string type is chosen by simply #defining an identifier.
43*9712c20fSFrederick Mayle //
44*9712c20fSFrederick Mayle // The solution:
45*9712c20fSFrederick Mayle // -------------
46*9712c20fSFrederick Mayle // #define HAS_GLOBAL_STRING somewhere in a global header file and then
47*9712c20fSFrederick Mayle // globally replace std::string with string.  Then include this header
48*9712c20fSFrederick Mayle // file everywhere where string is used.  If you want to revert back to
49*9712c20fSFrederick Mayle // using std::string, simply remove the #define (HAS_GLOBAL_STRING).
