      3 # This script is an almost total rewrite by Louwrentius 
      4 # of the original fio_generate_plots script provided as part of the FIO storage
      5 # benchmark utiliy. I only retained how GNUplot is used to generate graphs, as
      6 # that is something I know nothing about.
      7 #
      8 # The script uses the files generated by FIO to create nice graphs in the
      9 # SVG format. This output format is supported by most modern browsers and
     10 # allows resolution independent graphs to be generated.
     11 #
     12 # This script supports GNUPLOT 4.4 and higher.
     13 # 
     14 # Version 1.0 @ 20121231
