# This script is an almost total rewrite by Louwrentius
# of the original fio_generate_plots script provided as part of the FIO storage
# benchmark utiliy. I only retained how GNUplot is used to generate graphs, as
# that is something I know nothing about.
#
# The script uses the files generated by FIO to create nice graphs in the
# SVG format. This output format is supported by most modern browsers and
# allows resolution independent graphs to be generated.
#
# This script supports GNUPLOT 4.4 and higher.

# Version 1.0 @ 20121231
