 An UEFI environment consist of two parts: a firmware with GUID protocol interfaces and a user library. We cannot change
 the former, but we can make the second friendlier. That's what POSIX-UEFI does for your application. It is a small API
 wrapper library around the GUID protocols, not a fully blown POSIX compatible libc implementation.
