    <para>
      <application>Qt</application> is a cross-platform application
      framework that is widely used for developing application software
      with a graphical user interface (GUI) (in which cases Qt is classified
      as a widget toolkit), and also used for developing non-GUI programs such
      as command-line tools and consoles for servers. One of the major users
      of <application>Qt</application> is <application>KDE</application>.

    <caution>
      <para>
        If you did not install some of the recommended dependencies, examine
        <command>./configure --help</command> output to check how to disable
        them or use internal versions bundled in the source tarball.

    </caution>

    <warning>
      <para>
        If <application>Qt4</application> is being reinstalled into the
        same directory as an existing instance, run the commands done by
        <systemitem class="username">root</systemitem>, such as
        <command>make install</command>, from a console or non-Qt4 based
        window manager. It overwrites <application>Qt4</application>
        libraries that should not be in use during the install process.
      </para>
    </warning>

    <note>
      <para>
        The build time and space required for the full
        <application>Qt</application> is quite long. The instructions below
        do not build the tutorials and examples. Removing the
        <parameter>-nomake</parameter> lines will create a complete build.
