AFS management scripts

I've been working desperately for the past couple of weeks to get as many of the AFS management scripts as we use as possible ready so that when I talked about them at the AFS Best Practices Workshop, people could actually get them off of my web site and try them out.

I didn't manage to get everything done, but there's now a fairly extensive collection of tools available, including some of the AFS commands I use the most frequently (frak to check read/write volumes before release and volcreate to manage volume creation, for example).

See the AFS section on my software page for all the scripts. From this point on, I'll post separate release announcements here when I upgrade them.
