<h2>Usage</h2>
<ol>
<li>Install scipy, e.g. <code>sudo aptitude install python-scipy</code>
<li>Build chrome.</li>
<li>Check out a known working version of webpagereply:
<pre>git -C $CHROME_DIR/third_party/webpagereplay checkout 7dbd94752d1cde5536ffc623a9e10a51721eff1d</pre>
</li>
<li>Run <code>callstats.py</code> with a web-page-replay archive:
<pre>$V8_DIR/tools/callstats.py run \
--replay-bin=$CHROME_SRC/third_party/webpagereplay/replay.py \
--replay-wpr=$INPUT_DIR/top25.wpr \
--js-flags="" \
--with-chrome=$CHROME_SRC/out/Release/chrome \
--sites-file=$INPUT_DIR/top25.json</pre>
</li>
<li>Move results file to a subdirectory: <code>mkdir $VERSION_DIR; mv *.txt $VERSION_DIR</code></li>
<li>Repeat from step 1 with a different configuration (e.g. <code>--js-flags="--nolazy"</code>).</li>
<li>Create the final results file: <code>./callstats.py json $VERSION_DIR1 $VERSION_DIR2 > result.json</code></li>
