+ V9FS: 9P2000 for Linux
+ ======================
+
+ABOUT
+=====
+
+v9fs is a Unix implementation of the Plan 9 9p remote filesystem protocol.
+
+This software was originally developed by Ron Minnich <rminnich@lanl.gov>
+and Maya Gokhale <maya@lanl.gov>. Additional development by Greg Watson
+<gwatson@lanl.gov> and most recently Eric Van Hensbergen
+<ericvh@gmail.com> and Latchesar Ionkov <lucho@ionkov.net>.
+
+USAGE
+=====
+
+For remote file server:
+
+ mount -t 9P 10.10.1.2 /mnt/9
+
+For Plan 9 From User Space applications (http://swtch.com/plan9)
+
+ mount -t 9P `namespace`/acme /mnt/9 -o proto=unix,name=$USER
+
+OPTIONS
+=======
+
+ proto=name select an alternative transport. Valid options are
+ currently:
+ unix - specifying a named pipe mount point
+ tcp - specifying a normal TCP/IP connection
+ fd - used passed file descriptors for connection
+ (see rfdno and wfdno)
+
+ name=name user name to attempt mount as on the remote server. The
+ server may override or ignore this value. Certain user
+ names may require authentication.
+
+ aname=name aname specifies the file tree to access when the server is
+ offering several exported file systems.
+
+ debug=n specifies debug level. The debug level is a bitmask.
+ 0x01 = display verbose error messages
+ 0x02 = developer debug (DEBUG_CURRENT)
+ 0x04 = display 9P trace
+ 0x08 = display VFS trace
+ 0x10 = display Marshalling debug
+ 0x20 = display RPC debug
+ 0x40 = display transport debug
+ 0x80 = display allocation debug
+
+ rfdno=n the file descriptor for reading with proto=fd
+
+ wfdno=n the file descriptor for writing with proto=fd
+
+ maxdata=n the number of bytes to use for 9P packet payload (msize)
+
+ port=n port to connect to on the remote server
+
+ timeout=n request timeouts (in ms) (default 60000ms)
+
+ noextend force legacy mode (no 9P2000.u semantics)
+
+ uid attempt to mount as a particular uid
+
+ gid attempt to mount with a particular gid
+
+ afid security channel - used by Plan 9 authentication protocols
+
+ nodevmap do not map special files - represent them as normal files.
+ This can be used to share devices/named pipes/sockets between
+ hosts. This functionality will be expanded in later versions.
+
+RESOURCES
+=========
+
+The Linux version of the 9P server, along with some client-side utilities
+can be found at http://v9fs.sf.net (along with a CVS repository of the
+development branch of this module). There are user and developer mailing
+lists here, as well as a bug-tracker.
+
+For more information on the Plan 9 Operating System check out
+http://plan9.bell-labs.com/plan9
+
+For information on Plan 9 from User Space (Plan 9 applications and libraries
+ported to Linux/BSD/OSX/etc) check out http://swtch.com/plan9
+
+
+STATUS
+======
+
+The 2.6 kernel support is working on PPC and x86.
+
+PLEASE USE THE SOURCEFORGE BUG-TRACKER TO REPORT PROBLEMS.
