   6
   7 This shows how auto-beaming settings can be overridden.

   9 The auto-beamer will only engrave beams that end when:
  10 @itemize @bullet
  11 @item  a rest is encountered
  12 @item
  13  another beam (entered manually) is encountered
  14 @item
  15  there's a 'gap' in the beam note's durations
  16 @end itemize
  17
  18 The beam will be ended also when now % beamAutoEnd = 0.
