+This is the base of the new NTVFS subsystem for Samba. The model for
+NTVFS backends is quite different than for the older style VFS
+backends, in particular:
+
+- the NTVFS backends receive windows style file names, although they
+ are in the unix charset (usually UTF8). This means the backend is
+ responsible for mapping windows filename conventions to unix
+ filename conventions if necessary
+
+- the NTVFS backends are responsible for changing effective UID before
+ calling any OS local filesystem operations (if needed). The
+ become_*() functions are provided to make this easier.
+
+- the NTVFS backends are responsible for resolving DFS paths
+
+- each NTVFS backend handles either disk, printer or IPC$ shares,
+ rather than one backend handling all types
+
+- the entry points of the NTVFS backends correspond closely with basic
+ SMB operations, wheres the old VFS was modelled directly on the
+ POSIX filesystem interface.
+
+- the NTVFS backends are responsible for all semantic mappings, such
+ as mapping dos file attributes, ACLs, file ownership and file times

+This is the 'CIFS on CIFS' backend for Samba. It provides a NTVFS
+backend that talks to a remote CIFS server. The primary aim of this
+backend is for debugging and development, although some poeple may
+find it useful as a CIFS gateway.
