14651da177e4SLinus Torvalds	  Coda is an advanced network file system, similar to NFS in that it
14661da177e4SLinus Torvalds	  enables you to mount file systems of a remote server and access them
14671da177e4SLinus Torvalds	  with regular Unix commands as if they were sitting on your hard
14681da177e4SLinus Torvalds	  disk.  Coda has several advantages over NFS: support for
14691da177e4SLinus Torvalds	  disconnected operation (e.g. for laptops), read/write server
14701da177e4SLinus Torvalds	  replication, security model for authentication and encryption,
14711da177e4SLinus Torvalds	  persistent client caches and write back caching.
14721da177e4SLinus Torvalds
14731da177e4SLinus Torvalds	  If you say Y here, your Linux box will be able to act as a Coda
14741da177e4SLinus Torvalds	  *client*.  You will need user level code as well, both for the
14751da177e4SLinus Torvalds	  client and server.  Servers are currently user level, i.e. they need
14761da177e4SLinus Torvalds	  no kernel support.  Please read
14771da177e4SLinus Torvalds	  <file:Documentation/filesystems/coda.txt> and check out the Coda
