<h2>Packaging a release<a class="headerlink" href="#packaging-a-release" title="Permalink to this headline">¶</a></h2>
<p>The <code class="docutils literal notranslate"><span class="pre">export</span></code> command is used to package a release, i.e. to
take a copy of the files and directories in a branch and
package them into a fresh directory or archive. For example,
this command will package the last committed version into
a <code class="docutils literal notranslate"><span class="pre">tar.gz</span></code> archive file:</p>
<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="n">bzr</span> <span class="n">export</span> <span class="o">../</span><span class="n">releases</span><span class="o">/</span><span class="n">my</span><span class="o">-</span><span class="n">stuff</span><span class="o">-</span><span class="mf">1.5</span><span class="o">.</span><span class="n">tar</span><span class="o">.</span><span class="n">gz</span>
</pre></div>
</div>
<p>The <code class="docutils literal notranslate"><span class="pre">export</span></code> command uses the suffix of the archive file
to work out the type of archive to create as shown below.</p>
<blockquote>
<div><table border="1" class="docutils">
<colgroup>
<col width="40%" />
<col width="60%" />
</colgroup>
<thead valign="bottom">
<tr class="row-odd"><th class="head">Supported formats</th>
<th class="head">Autodetected by extension</th>
</tr>
</thead>
<tbody valign="top">
<tr class="row-even"><td>dir</td>
<td>(none)</td>
</tr>
<tr class="row-odd"><td>tar</td>
<td>.tar</td>
</tr>
<tr class="row-even"><td>tbz2</td>
<td>.tar.bz2, .tbz2</td>
</tr>
<tr class="row-odd"><td>tgz</td>
<td>.tar.gz, .tgz</td>
</tr>
<tr class="row-even"><td>zip</td>
<td>.zip</td>
</tr>
</tbody>
</table>
</div></blockquote>
<p>If you wish to package a revision other than the last one, use
the <code class="docutils literal notranslate"><span class="pre">-r</span></code> option. If you wish to tune the root directory inside
the archive, use the <code class="docutils literal notranslate"><span class="pre">--root</span></code> option. See the online help or
User Reference for further details on the options supported by
<code class="docutils literal notranslate"><span class="pre">export</span></code>.</p>
</div>
<div class="section" id="tagging-a-release">
<h2>Tagging a release<a class="headerlink" href="#tagging-a-release" title="Permalink to this headline">¶</a></h2>
<p>Rather than remembering which version was used to package a release,
it’s useful to define a symbolic name for a version using the <code class="docutils literal notranslate"><span class="pre">tag</span></code>
command like this:</p>
<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="n">bzr</span> <span class="n">tag</span> <span class="n">version</span><span class="o">-</span><span class="mi">1</span><span class="o">-</span><span class="mi">5</span>
</pre></div>
</div>
<p>That tag can be used later whenever a revision identifier is
required, e.g.:</p>
<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="n">bzr</span> <span class="n">diff</span> <span class="o">-</span><span class="n">r</span> <span class="n">tag</span><span class="p">:</span><span class="n">version</span><span class="o">-</span><span class="mi">1</span><span class="o">-</span><span class="mi">5</span>
</pre></div>
</div>
<p>To see the list of tags defined in a branch, use the <code class="docutils literal notranslate"><span class="pre">tags</span></code> command.</p>
