# 0.0.1		Initial creation by Brad Knowles <brad@stop.mail-abuse.org>
#		Created on: Tue Feb 15 04:01:20 PST 2005
#
# 0.0.2         Update by Brad Knowles <brad@stop.mail-abuse.org>
#               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.
