+This is a header-only single-file std::filesystem compatible helper library,
+based on the C++17 specs, but implemented for C++11 or C++14 (so not 100%
+conforming to the C++17 standard). It is currently tested on macOS 10.12, Windows 10,
+and Ubuntu 18.04 but should work on other versions too, as long as you have a
+C++11 compatible compiler.
