aq.org local information

• A little tuturial on using procmail to filter your mail, based on something I wrote at work.
• There used to be a local copy of the manual for version 3.10a of the xv image viewer (whose home is at http://www.trilon.com/xv/) here, but I seem to have mislaid it.
• If you administer Mailman lists on aq.org, you might want to look at the Mailman documentation at http://www.list.org/, and in particular at Christopher Kolar's Manager's Guide linked at http://www.aurora.edu/~ckolar/mailman/. (These documents aren't local, but they’re locally useful.)
