/**
|
|
* @namespace G4fs
|
|
* Namespace adapter for `filesystem` in `std::` or `std::experimental::`
|
|
*
|
|
* Developers should use this namespace to scope into the C++ filesystem
|
|
* library, e.g.
|
|
*
|
|
* ```cpp
|
|
* // Don't use std:: directly...
|
|
* auto p = std::filesystem::path{ argv[0] };
|
|
*
|
|
* // ... use the alias
|
|
* auto p = G4fs::path{ argv[0] };
|
|
* ```
|
|
*
|
|
* This allows compatibility with C++ standard libraries that only provide
|
|
* `filesystem` in the `std::experimental` namespace
|
|
*
