9121da177e4SLinus Torvalds	  Coda is an advanced network file system, similar to NFS in that it
9131da177e4SLinus Torvalds	  enables you to mount file systems of a remote server and access them
9141da177e4SLinus Torvalds	  with regular Unix commands as if they were sitting on your hard
9151da177e4SLinus Torvalds	  disk.  Coda has several advantages over NFS: support for
9161da177e4SLinus Torvalds	  disconnected operation (e.g. for laptops), read/write server
9171da177e4SLinus Torvalds	  replication, security model for authentication and encryption,
9181da177e4SLinus Torvalds	  persistent client caches and write back caching.

9201da177e4SLinus Torvalds	  If you say Y here, your Linux box will be able to act as a Coda
9211da177e4SLinus Torvalds	  *client*.  You will need user level code as well, both for the
9221da177e4SLinus Torvalds	  client and server.  Servers are currently user level, i.e. they need
9231da177e4SLinus Torvalds	  no kernel support.  Please read
9241da177e4SLinus Torvalds	  <file:Documentation/filesystems/coda.txt> and check out the Coda
