     -col-name-width <int>
  The maximum width for the column names (0 = optimal).
  (default: 0)
     -row-name-width <int>
  The maximum width for the row names (0 = optimal).
  (default: 40)
     -mean-width <int>
  The width of the mean (0 = optimal).
  (default: 0)
     -stddev-width <int>
  The width of the standard deviation (0 = optimal).
  (default: 0)
     -sig-width <int>
  The width of the significance indicator (0 = optimal).
  (default: 0)
     -count-width <int>
  The width of the counts (0 = optimal).
  (default: 0)
     -show-stddev
  Whether to display the standard deviation column.
  (default: no)
     -show-avg
  Whether to show the row with averages.
  (default: no)
     -remove-filter
  Whether to remove the classname package prefixes from the
  filter names in datasets.
  (default: no)
     -print-col-names
  Whether to output column names or just numbers representing them.
  (default: no)
     -print-row-names
  Whether to output row names or just numbers representing them.
  (default: no)
     -enum-col-names
  Whether to enumerate the column names (prefixing them with 
  '(x)', with 'x' being the index).
  (default: no)
     -enum-row-names
