          Both <application>Python 2</application> and
          <application>Python 3</application> modules can
          be built and installed without any conflicts.
        </para>
      </note>

<!-- Editors note: Use - -root= instead of DESTDIR= when updating. -->

      <para>
        To build both <application>Python 2</application> and
        <application>Python 3</application> modules, run:
      </para>

<screen><userinput>python2 setup.py build &amp;&amp;
python3 setup.py build</userinput></screen>

     <para>
       If you wish to run the tests, enter:
       <command>make PYTHON=python2 test</command> and
       <command>make PYTHON=python3 test</command>.
       This will rebuild the package for inplace use before running the tests.
       Seven tests are known to fail due to a missing file.
     </para>

      <para>
        To install both modules, issue the following commands as the
        <systemitem class="username">root</systemitem> user:
      </para>

<screen role="root"><userinput>python2 setup.py install --optimize=1 &amp;&amp;
