+/// The error type returned on unsupported platforms.
+///
+/// On unsupported platforms, all operations will fail with an `io::Error` with
+/// a kind `io::ErrorKind::Other` and an `UnsupportedPlatformError` error as the inner error.
+/// While you *could* check the inner error, it's probably simpler just to check
+/// `xattr::SUPPORTED_PLATFORM`.
+///
+/// This error mostly exists for pretty error messages.
