//
// In your usual header, do something like:
//
//   #define __glibcxx_want_ranges
//   #define __glibcxx_want_concepts
//   #include <bits/version.h>
//
// This will generate the FTMs you named, and let you use them in your code as
// if it was user code.  All macros are also exposed under __glibcxx_NAME even
// if unwanted, to permit bits and other FTMs to depend on them for condtional
// computation without exposing extra FTMs to user code.
