+#!/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.
