# $Log: check_ms_spooler.pl,v $
# 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.
