35 //
36 // In your usual header, do something like:
37 //
38 // #define __glibcxx_want_ranges
39 // #define __glibcxx_want_concepts
40 // #include <bits/version.h>
41 //
42 // This will generate the FTMs you named, and let you use them in your code as
43 // if it was user code. All macros are also exposed under __glibcxx_NAME even
44 // if unwanted, to permit bits and other FTMs to depend on them for condtional
45 // computation without exposing extra FTMs to user code.
