It's only in the 1.5 development series, and there isn't much =
documentation currently available. Here's a quick summary...

The code needs to be built with --enabled-disconnected (which Mac OS X =
builds, and some Linux packages already have enabled).

Before working offline, you first need to populate your cache with =
something like:

find /path/of/files/i/want/while/disconnected | xargs cat > /dev/null


fs discon offline

will disconnect you from the AFS fileservers. You can then modify any of =
the files you populated earlier and

fs discon online

will replay any changes you have made back to the fileserver. The one =
caveat, currently, is that your cache is not preserved across reboots. =
If you reboot, or if your machine crashes, before you go back online, =
then any changes you made locally will be lost.
