14631da177e4SLinus Torvalds	  Coda is an advanced network file system, similar to NFS in that it
14641da177e4SLinus Torvalds	  enables you to mount file systems of a remote server and access them
14651da177e4SLinus Torvalds	  with regular Unix commands as if they were sitting on your hard
14661da177e4SLinus Torvalds	  disk.  Coda has several advantages over NFS: support for
14671da177e4SLinus Torvalds	  disconnected operation (e.g. for laptops), read/write server
14681da177e4SLinus Torvalds	  replication, security model for authentication and encryption,
14691da177e4SLinus Torvalds	  persistent client caches and write back caching.
