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.
