* they were saved using a filed on the same platform.

* Currently we support the following OSes:
- * - FreeBSD (Extended Attributes)
* - Darwin (Extended Attributes)
* - Linux (Extended Attributes)
* - NetBSD (Extended Attributes)
+ * - FreeBSD (Extended Attributes)
+ * - OpenBSD (Extended Attributes)
+ * (As it seems either they never implemented xattr or they are removed
+ * the support as it stated it was in version 3.1 but the current syscall
+ * tabled shows the extattr_ functions are not implemented. So as such we
+ * might eventually support xattr on OpenBSD when they implemented them using
+ * the same interface as FreeBSD and NetBSD.
