224 | mtools ("man mtools") program suite. You don't need to say Y here in | |

1281 | If you say Y here, your Linux box will be able to act as a Coda | |
1282 | *client*. You will need user level code as well, both for the | |
1283 | client and server. Servers are currently user level, i.e. they need | |
1284 | no kernel support. Please read | |
1285 | <file:Documentation/filesystems/coda.txt> and check out the Coda | |
1286 | home page <http://www.coda.cs.cmu.edu/>. | |
1287 | ||
1288 | To compile the coda client support as a module, choose M here: the | |
1289 | module will be called coda. | |
