+# Revision 1.1  2002/07/16 00:04:42  stanleyhopcroft
+# Primitive and in need of refinement test of MS spooler (with smbclient)
+#
+# Revision 2.5  2002-02-13 07:36:08+11  anwsmh
+# Correct 'apostrophe' disaster.
+# Apostrophes in plugin output cause Netsaint notification commands
+# ( sh echo 'yada $PLUGINOUTPUT$ ..') to fail, usually mysteriously
+# eg notify OK works but notify CRITICAL does not.
+# Replace '$var' in print "output" with \"$var\".
+#
+# Revision 2.4  2001-11-21 21:36:05+11  anwsmh
+# Minor corrections
+#  . replace 'die' by print .. exit $ERRORS{CRITICAL}
+#  . change concluding message to list the queues (sorted) if there are no enqueued docs.
+#
+# Revision 2.3  2001-11-20 11:00:58+11  anwsmh
+# Major corrections.
+#  1. to sub AUTOLOAD: coderef parms must be @_ (ie the parm when the new sub is called)
+#  2. to processing of queue report (no inspection of $last_line; entire $queue_report is
+#     checked for errors)
+#  3. cosmetic and debug changes in many places.
+#
+# Revision 2.2  2001-11-17 23:30:34+11  anwsmh
+# After adapting two different queue reports resulting from
+# different name resolution methods.
+#
+# Revision 2.1  2001-11-17 13:21:54+11  anwsmh
+# Adapt to Netsaint ('use utils, Getopt::Long, and standard switch processing).
+# Fix many peculiarities.
