36 * This macro is a string describing the source at a particular point in
37 * development.
38 *
39 * This string is often generated from revision control's state at build time.
40 *
41 * This string can be quite complex and does not follow any standard. For
42 * example, it might be something like "SDL-prerelease-3.1.1-47-gf687e0732".
43 * It might also be user-defined at build time, so it's best to treat it as a
44 * clue in debugging forensics and not something the app will parse in any
45 * way.
46 *
47 * SDL_revision.h must be included in your program explicitly if you want
48 * access to the SDL_REVISION constant.
49 *
50 * \since This macro is available since SDL 3.2.0.
