Abstract

   A new URL scheme, 'nfs' is defined.  It is used to refer to files and
   directories on NFS servers using the general URL syntax defined in
   RFC 1738, "Uniform Resource Locators (URL)".

   This scheme uses the public filehandle and multi-component lookup
   [RFC 2054, RFC 2055] to access server data with a minimum of protocol
   overhead.

   The NFS protocol provides access to shared filesystems across
   networks.  It is designed to be machine, operating system, network
   architecture, and transport protocol independent.  The protocol
   currently exists in two versions: version 2 [RFC 1094] and version 3
   [RFC 1813], both built on ONC RPC [RFC 1831] at its associated eXternal
   Data Representation (XDR) [RFC 1832] and Binding Protocol [RFC 1833].
