Summary:	An implementation of C++17 std::filesystem for C++11 /C++14/C++17/C++20
Name:		gulrak-filesystem
Version:	1.5.14
Release:	1

%description
This is a header-only single-file std::filesystem compatible helper library,
based on the C++17 and C++20 specs, but implemented for C++11, C++14, C++17 or
C++20 (tightly following  the C++17 standard with very few documented exceptions).
It is currently tested on macOS 10.12/10.14/10.15/11.6, Windows 10, Ubuntu 18.04,
Ubuntu 20.04, CentOS 7, CentOS 8, FreeBSD 12, Alpine ARM/ARM64 Linux and Solaris
10 but should work on other systems too, as long as you have at least a C++11
compatible compiler. It should work with Android NDK, Emscripten and I even had
reports of it being used on iOS (within sandboxing constraints) and with v1.5.6
there is experimental support for QNX. The support of Android NDK, Emscripten and
QNX is not backed up by automated testing but PRs and bug reports are welcome for
those too. It is of course in its own namespace `ghc::filesystem` to not interfere
with a regular std::filesystem should you use it in a mixed C++17 environment
(which is possible).
