#               Updated on: Wed Feb 16 18:55:52 CET 2005
#               Feedback from Tom G. Christensen (tgc99):
#               > The current UID grab command doesn't work on Solaris 
#               > (2.6 & 8 tested).      
#               >
#               > I'd recommend this instead:
#               > ps -o user -p $$|tail -1
#               >
#               > This is tested and works on RH 6.2, RH 7.3, RHEL 2.1,
#               > RHEL3, FC3, FreeBSD 4.9, Solaris 2.6, 8.

# 0.0.3         Update by Brad Knowles <brad@stop.mail-abuse.org>
#               Updated on: Sun Mar 13 01:15:24 CET 2005
#               Noted errors from grep when trying to search a nonexistant
#               file.  Added "-s" option to compensate, and extra code to
#		notify the admin if the log file doesn't exist.
#
# 0.0.4         Update by Brad Knowles <brad@stop.mail-abuse.org>
#               Updated on: Sun Mar 13 01:58:37 CET 2005
#               Eliminate some extra cruft from the "fromusenet" logs.
#
# 0.0.5         Update by Brad Knowles <brad@stop.mail-abuse.org>
#               Updated on: Wed Apr 13 00:54:42 CEST 2005
#		Eliminate a lot of extra cruft from the "error" & "vette" logs.
#               Eliminate more cruft from the "fromusenet" logs.
#
# 0.0.6         Update by Brad Knowles <brad@stop.mail-abuse.org>
#               Updated on: Thu Apr 14 03:07:08 CEST 2005
#               Eliminate even more cruft from the "fromusenet" logs.
#               Eliminate more cruft from the "vette" logs.
#               Eliminate cruft from the "mischief" logs.
#
# 0.0.7         Update by Brad Knowles <brad@stop.mail-abuse.org>
#               Updated on: Sun May  1 22:29:13 CEST 2005   [guess]
#		The "error" log "no such list" errors didn't need to be
#		quite so "compressed", open them up to be more readable.
#		Also eliminate all use of "xargs", use "fmt -w 75" instead.
#
# 0.0.8         Update by Brad Knowles <brad@stop.mail-abuse.org>
#               Updated on: Sun May  1 23:09:13 CEST 2005
#		Clean up code for queue subdirectories to check.
#
# 0.0.9         Update by Brad Knowles <brad@stop.mail-abuse.org>
#               Updated on: Wed May 11 01:23:40 CEST 2005
#		Eliminate date/time stamps from the rest of the logs,
#		then pipe through `sort | uniq -c | sort -nr`
#		so that all possible duplicates are eliminated.
#
# 0.0.10	Update by Brad Knowles <brad@stop.mail-abuse.org>
#		Updated on: Tue Jul 12 16:53:49 CDT 2005
#		Add code to do summary of normal list activity
#
# 0.0.11	Update by Brad Knowles <brad@stop.mail-abuse.org>
#		Updated on: Tue Sep  6 15:44:19 CEST 2005
#		Tweaked display of Mailman/qfiles subdirectories
#		so as to avoid displaying more than $MAX_LINES
#		output, which really helps if you have thousands
#		of bounces sitting around, etc....
#		Also slightly tweaked display of fromusenet logs
#		to split summary from errors.
#
# 0.0.12	Update by Brad Knowles <brad@stop.mail-abuse.org>
#		Updated on: Thu Sep 22 22:37:35 CEST 2005
#		Bugs found by Mark Sapiro and Adrian Wells.
#		Mark suggested splitting the Mailman log directory
#		from the rest of the Mailman source and queues,
#		as well as making sure to clean up all temp files.
#		Adrian discovered that there was a log file format
#		change between Mailman 2.1.5 and 2.1.6, which broke
#		hourly statistics.
#
# 0.0.13	Update by Brad Knowles <brad@stop.mail-abuse.org>
#		Updated on: Mon Dec 26 05:54:27 CET 2005
#		Bugs found by Tom G. Christensen (tgc99):
#		> ps output on solaris is full of whitespace but a further
#		> echo get's rid of it.
#		> The lines in the smtp log are sometimes broken up by a
#		> newline (right before the msgid) which throws of the
#		> summary. Piping it through sed first will rejoin the broken
#		> lines.
#		> Use $AWK instead of awk.
#		Enhancements from Mark Sapiro:
#		> The vette log summary lists posts held for moderation
#		> individually under "Other Errors:". The following patch
#		> (watch out for wrapped lines) summarizes them by list instead.
#
# 0.0.14	Update by Brad Knowles <brad@stop.mail-abuse.org>
#		Updated on: Thu Dec 29 08:17:38 CET 2005
#		Added code to check /usr/local/mailman/data for
#		moderation hold queue
#
# 0.0.15	Update by Brad Knowles <brad@stop.mail-abuse.org>
#		Updated on: Thu Jan 26 02:39:38 CET 2006
#		Tweaked display of summary data in the "smtp-failure" log,
#		and "other" category in the "vette" log, so as to reduce
#		the spewage when things go wonky, mostly by removing
#		unique-ifying data like message-id or sender address.
#		Also tweaked moderation queue information, to tell us
#		how many Python pickle files are in the data directory,
#		as opposed to just doing a directory listing and skipping
#		the files in the middle if there are too many -- now we
#		know how many are being skipped.
#
# 0.0.16	Update by Brad Knowles <brad@stop.mail-abuse.org>
#		Updated on: Sun Jan 29 11:45:58 CET 2006
#		Mark found a couple of typos that I somehow let slip
#		through.  Thanks!
#
# 0.0.17	Update by Mark Sapiro <mark@msapiro.net>
#		Updated on: Thu Jan  3 18:25:06 PST 2008
#		Enabled processing the prior generation of a rotated log.
#		Added SORT_FIELD to the user modifiable parameters.
#
# 0.0.18	Update by Mark Sapiro <mark@msapiro.net>
#		Updated on: Tue May 13 08:58:26 PDT 2008
#		Changes for Mailman 2.1.10 --
#		Added 'bad' to the list of queues.
#		Made listing of a queue directory conditional on existence.
#		Sumarized unparseable messages and preserved queue entries
#		in the Other Errors section.
#
# 0.0.19	Update by Mark Sapiro <mark@msapiro.net>
#		Updated on: Sun Nov 30 10:26:15 PST 2008
#		Changed processing of fromusenet posts.  Previously, mmdsr
#		reported as gated only the first and last of a gated range.
#		Now mmdsr reports every post from the 'posted to' entries.
#
# 0.0.20	Update by Mark Sapiro <mark@msapiro.net>
#		Updated on: Sun Jul 26 08:56:41 PDT 2009
#		Added report of files in the preserved messages directory.
#
# 0.0.21	Update by Mark Sapiro <mark@msapiro.net>
#		Updated on: Sun Sep 27 12:45:44 PDT 2009
#		Refactored to use mktemp to create temp files
