733 help
734 Coda is an advanced network file system, similar to NFS in that it
735 enables you to mount file systems of a remote server and access them
736 with regular Unix commands as if they were sitting on your hard
737 disk. Coda has several advantages over NFS: support for
738 disconnected operation (e.g. for laptops), read/write server
739 replication, security model for authentication and encryption,
740 persistent client caches and write back caching.
741
742 If you say Y here, your Linux box will be able to act as a Coda
743 *client*. You will need user level code as well, both for the
744 client and server. Servers are currently user level, i.e. they need
745 no kernel support. Please read
746 <file:Documentation/filesystems/coda.txt> and check out the Coda
747 home page <http://www.coda.cs.cmu.edu/>.
748
749 To compile the coda client support as a module, choose M here: the
750 module will be called coda.
