    <para>
      <command>sed -i s/3000/5000/ ...</command>: this increases the recursion
      limit in libxslt. This is needed by some packages for their documentation.
    </para>

    <para>
      <parameter>--without-python</parameter>: This parameter disables the libxslt
      python module since it does not support Python3. If you wish to enable
      this module, make sure that <xref role="nodep" linkend="libxml2py2"/> is
      installed, and remove this parameter.
