cjihrig a69ab27ab4 node: rename from io.js to node
This commit replaces instances of io.js with Node.js, based on the
recent convergence. There are some remaining instances of io.js,
related to build and the installer.

Fixes: https://github.com/nodejs/node/issues/2361
PR-URL: https://github.com/nodejs/node/pull/2367

#!/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.
