This filesystem provides a fairly simple secure AFS filesystem driver. It is
under development and does not yet provide the full feature set. The features
it does support include:
* Security (currently only AFS kaserver and KerberosIV tickets).
* File reading and writing.
* Automounting.
* Local caching (via fscache).
It does not yet support the following AFS features:
* pioctl() system call.
