<h3>Log Message</h3>
<pre>2010-03-19  Adam Barth  &lt;abarth@webkit.org&gt;

        Reviewed by Eric Seidel.

        Second cut at SheriffBot
        https://bugs.webkit.org/show_bug.cgi?id=36353

        This patch should contain a complete SheriffBot that's capable of
        saying reasonable things on IRC.  I had to refactor the use of
        CommitInfo to make the SheriffBot testable, but I did the minimum
        necessary.  We should grow webkitcheckout over time to contain the
        knowledge of ChangeLogs from scm.
