{- Portability shim around System.Posix.Files.ByteString

-
|
|
- On unix, this makes syscalls using RawFilesPaths as efficiently as
|
|
- possible.
|
|
-
|
|
- On Windows, filenames are in unicode, so RawFilePaths have to be
|
|
- decoded. So this library will work, but less efficiently than using
|
|
- FilePath would.
