#!/usr/bin/env Rscript
# To use this script you'll need to install R: http://www.r-project.org/
# and a library for R called ggplot2
# Which can be done by starting R and typing install.packages("ggplot2")
# like this:
#
# shell% R
# R version 2.11.0 beta (2010-04-12 r51689)
# > install.packages("ggplot2")
# (follow prompt)
#
# Then you can try this script by providing a full path to .data file
# outputed from 'make bench'
#
# > cd ~/src/node
# > make bench
# ...
# > ./benchmark/plot.R .benchmark_reports/ab-hello-world-buffer-1024/ff456b38862de3fd0118c6ac6b3f46edb1fbb87f/20101013162056.data
#
# This will generate a PNG file which you can view
#
#
# Hopefully these steps will be automated in the future.
