      The <application>qtchooser</application> package contains a wrapper used to select
      between <application>Qt</application> binary versions.  It is only needed if
      both Qt4 and Qt5 are installed for access via the /usr/bin directory.

      <title>Configuration Information</title>

      <para>
        The <filename>/etc/xdg/qtchooser/default.conf</filename>
        configuration file contains paths to the
        <application>Qt</application> binaries and libraries which will
        be used when the wrapper is run. It is ussually a symlink to a
        package specific file, such as <filename>4.conf</filename> or
        <filename>5.conf</filename>. In first case, when invoking the wrappers,
        <application>Qt4</application> equivalents will be invoked. In second
        case, <application>Qt5</application> equivalents will be invoked.
      </para>

      <para>
        Create the configuration files by running the following commands as
        the <systemitem class="username">root</systemitem> user:

      <para>
        To set <application>Qt4</application> as the default, run the following

<screen role="root"><userinput>ln -sfv 4.conf /etc/xdg/qtchooser/default.conf</userinput></screen>

      <para>
        You can also select default <application>Qt</application> using an environment
        variable.
