/**
* This macro is a string describing the source at a particular point in development.
*
* This string is often generated from revision control's state at build time.
*
* This string can be quite complex and does not follow any standard.
* For example, it might be something like "SDL-prerelease-3.1.1-47-gf687e0732".
* It might also be user-defined at build time, so it's best to treat it as
* a clue in debugging forensics and not something the app will parse in any way.
*
* \since This macro is available since SDL 3.0.0.
