// fs_std_fwd.hpp - The forwarding header for the header/implementation seperated usage of
//                  ghc::filesystem that uses std::filesystem if it detects it.
// This file can be include at any place, where fs::filesystem api is needed while
// not bleeding implementation details (e.g. system includes) into the global namespace,
// as long as one cpp includes fs_std_impl.hpp to deliver the matching implementations.
