// Update the metadata index for all archives in the database
// This script is intended to be called by a cron script (via command-line PHP) to
// automatically update the index periodically. It should be placed somewhere outside
// the web documents directory and run from cron as an unprivileged user.
// Takes an optional argument specifying a specific archive to update.
// Default behaviour is to update all archives.
