      <application>Poppler</application> will automatically read them if they
      are present. When installed, they enable

      In order to optionally run the test suite, an additional download of about
      9 MB using <xref linkend="git"/> is necessary. Make sure that you do
      not have the directory ../test.
    </para>

    <note><para>
      This package can be optionally built with support for either the Qt4 or
      Qt5 libraries, but it only builds with one of those at a time. If you
      have both Qt versions installed, you will need to specify which one to
      use before executing the <command>configure</command> command given
      below. Use this command to link to Qt4: 
      
      <screen><userinput>source /usr/bin/setqt4</userinput></screen> 

      or use this to use Qt5:

      <screen><userinput>source /usr/bin/setqt5</userinput></screen> 

      If you would like <application>Poppler</application> to link to both Qt
      versions, you will need to build it twice.
