> ==Step 1: Setup Pharo and a Fresh Image==
>
>   * download a Pharo image, the sources file, and a VM from the
>     [http://www.pharo-project.org/pharo-download download page]
>   * extract all archives in the same folder
>   * start Pharo, from the commandline, on a MacOSX it should look

>     {{{
>        "Squeak 4.2.1beta1U.app/Contents/MacOS/Squeak VM Opt" \
>           pharo1.0-10418-BETAdev09.08.3.image
>     }}}
>
> ==Step 2: Load OSProcess==
>
> For output on the shell, we need an extra package from the

> It can be loaded by simply executing the following code in a workspace

>
> {{{
> ScriptLoader loadLatestPackage: 'OSProcess' from:
> 'http://www.squeaksource.com/OSProcess'
> }}}
>
> To execute this code snippet, select it and press cmd+d or use the "do
> it"
> item in the context menu.
>
> ==Step 3: Load Common Benchmark Code==
>
> Now we can load the common parts of all shootout benchmarks into our
> image.
>
>   * On way to do this is to grab the code shown [http://shootout.alioth.debian.org/gp4/benchmark.php?test=all&lang=squeak&lang2=squeak 
>  here
> ]
> and save it to a file called `common.st`.
>   * Open the file browser from the Menu -> Tools -> File Browser.
>   * Select `common.st` and press `filein` to load the code.
>
> Now you can close all windows in your image and save and quit it.
>
> ==Step 4: Run a Benchmark==
>
>   * Grab the code of a benchmark like [http://shootout.alioth.debian.org/gp4/benchmark.php?test=fannkuch&lang=squeak&id=1 
>  Fannkuch
> ]
>   * Save it to a file named like `fannkuch.st`
>   * Add a run script to the end of the code in `fannkuch.st`, like
> this:
> {{{
>     Tests fannkuch.
>     SmalltalkImage current snapshot: false andQuit: true.
> }}}
>   * Run it with a headless Pharo:
> {{{
>     "Squeak 4.2.1beta1U.app/Contents/MacOS/Squeak VM Opt" \
>         -headless pharo1.0-10418-BETAdev09.08.3.image \
>         $PWD/fannkuch.st 6
> }}}
