  #            - 1.0 -     - Initial creation.
  # 2008-02-20 - 1.1 - KBB - Made autodetect_regular_expression more restrictive, since this
  # format is so consistent. Fixed bug where user agent field was not being set because of an
  # extra field being gathered. (My original assumption was that there was a format variant that
  # lacked the server_domain field, but we have many samples of icecast logs and they are all the
  # same, so I think it was a bug. If this breaks backward compatibility to an earlier default,
  # or a common variant, then that must be addressed. I don't know if icecast logging uses format
  # strings like Apache.)
  # 2008-02-20 - 1.2 - KBB - Based on information from icecast.org forum,
  # http://icecast.imux.net/viewtopic.php?t=655&highlight=log+format, am now gathering final
  # numeric field as the duration in seconds. I have used this to replace the previous duration
  # which as calculated from the size and an assumption about the speed.
  # 2008-02-20 - 1.3 - GMF - Moved "accesses=1" to its own filter, so it can be automatically disabled
  #                          when accesses does not exist.
