    • Instead of keeping individual debug flags for each Sieve machine,
      use global debugging mechanism, category "sieve".  The following
      levels are defined:
      
        trace1  -  print parse tree before optimization
        trace2  -  print parse tree after optimization
        trace3  -  print parser traces
