   5 # Revision 1.1  2002/07/16 00:04:42  stanleyhopcroft
   6 # Primitive and in need of refinement test of MS spooler (with smbclient)
   7 #
   8 # Revision 2.5  2002-02-13 07:36:08+11  anwsmh
   9 # Correct 'apostrophe' disaster.
  10 # Apostrophes in plugin output cause Netsaint notification commands
  11 # ( sh echo 'yada $PLUGINOUTPUT$ ..') to fail, usually mysteriously
  12 # eg notify OK works but notify CRITICAL does not.
  13 # Replace '$var' in print "output" with \"$var\".
  14 #
  15 # Revision 2.4  2001-11-21 21:36:05+11  anwsmh
  16 # Minor corrections
  17 #  . replace 'die' by print .. exit $ERRORS{CRITICAL}
  18 #  . change concluding message to list the queues (sorted) if there are no enqueued docs.
  19 #
  20 # Revision 2.3  2001-11-20 11:00:58+11  anwsmh
  21 # Major corrections.
  22 #  1. to sub AUTOLOAD: coderef parms must be @_ (ie the parm when the new sub is called)
  23 #  2. to processing of queue report (no inspection of $last_line; entire $queue_report is
  24 #     checked for errors)
  25 #  3. cosmetic and debug changes in many places.
  26 #
  27 # Revision 2.2  2001-11-17 23:30:34+11  anwsmh
