-<!--{
-	"Title": "Using Mercurial Queues with Codereview"
-}-->
-
-<h2 id="Introduction">Introduction</h2>
-
-<p>
-The Mercurial Queues extension (<code>mq</code>) provides a mechanism for
-managing patches on top of a Mercurial repository and is described in detail
-in Chapters
-<a href="http://hgbook.red-bean.com/read/managing-change-with-mercurial-queues.html">12</a>
-and <a href="http://hgbook.red-bean.com/read/advanced-uses-of-mercurial-queues.html">13</a>
-of <a href="http://hgbook.red-bean.com/read/">Mercurial: The Definitive Guide</a>.
-This document explains how to use <code>mq</code> in conjunction
-with the <code>codereview</code> Mercurial extension described in the
-instructions for <a href="contribute.html">contributing to the Go project</a>.
-It assumes you have read those instructions.
-</p>
-
-<h2>Configuration</h2>
-
-<p>
-To enable <code>mq</code> edit either <code>$HOME/.hgrc</code> (to enable it
-for all of your repositories) or <code>$GOROOT/.hg/hgrc</code> (to enable it for the
-repository at <code>$GOROOT</code>) to add:</p>
-
-<pre>
-[extensions]
-mq=
-</pre>
-
-<p>
-Since pulling, pushing, updating and committing while <code>mq</code> patches
-are applied can damage your repository or a remote one, add these lines to
-prevent that case: 
-</p>
-
-<pre>
-[hooks]
-# Prevent "hg pull" if MQ patches are applied.
-prechangegroup.mq-no-pull = ! hg qtop > /dev/null 2>&amp;1
-# Prevent "hg push" if MQ patches are applied.
-preoutgoing.mq-no-push = ! hg qtop > /dev/null 2>&amp;1
-# Prevent "hg update" if MQ patches are applied.
-preupdate.mq-no-update = ! hg qtop > /dev/null 2>&amp;1
-</pre>
-
-<h2>Making a change</h2>
-
-<p>
-The entire checked-out tree is writable and you can use <code>mq</code>,
-as documented in Chapter
-<a href="http://hgbook.red-bean.com/read/managing-change-with-mercurial-queues.html">12</a>
-of "The Guide",
-to implement your change as a single patch or a series of patches.
-
-</p>
-
-<p>When you are ready to send a change out for review, run</p>
-
-<pre>
-$ hg change
-</pre>
-
-<p>from any directory in your Go repository with all of the <code>mq</code> patches relevant to your
-change applied and then proceed as instructed in <a href="contribute.html">contributing
-to the Go project</a>.
-</p>
-
-<p>
-The change number reported by <code>hg change</code>, preceded by a <code>+</code>,
-can be used as an <code>mq</code> patch guard to assist in controlling which patches
-are applied as described in Chapter
-<a href="http://hgbook.red-bean.com/read/advanced-uses-of-mercurial-queues.html">13</a>
-of "The Guide".
-For example, the command:
-</p>
-
-<pre>
-for p in $(hg qapplied); do hg qguard $p +99999; done
-</pre>
-
-<p>
-will apply the guard <code>+99999</code> guard to all currently applied <code>mq</code>
-patches.
-</p>
-
-<h2>Synchronizing your client</h2>
-
-<p>While you were working, others might have submitted changes
-to the repository and, as explained in <a href="contribute.html">contributing
-to the Go project</a>, it is necessary to synchronize your repository using
-<code>hg sync</code>before sending your change list for review.
-Because <code>hg sync</code> runs <code>hg pull -u</code>,
-you should not run <code>hg sync</code> while <code>mq</code> patches are
-applied. Instead
-pop all your patches before running <code>hg sync</code> and reapply them after
-it has completed.
-</p>
-
-<p>
-When reapplying the patches, you may need to resolve conflicts
-as described in <a href="contribute.html">contributing to the Go project</a>.
-</p>
-
-<h2>Mailing the change for review</h2>
-
-<p>
-You should have all of the <code>mq</code> patches relevant to your
-change applied when you run <code>hg mail</code>.
-
-<h2>Submitting the change after the review</h2>
-
-If you are a committer, you should have all of the <code>mq</code> patches relevant to your
-change applied when you run <code>hg commit</code>.
