make</userinput></screen>
<!-- make bootstrap only necessary for development versions obtained with git
-->

    <para>
      This package does not come with a test suite. If make succeeds, you can
      test the result by running <command>src/emacs -Q</command>, which is the
      program that will be installed, with its auxiliary files. This should
      start and display the application opening screen.
    </para>

    <para>Now, as the <systemitem class="username">root</systemitem> user:</para>

      This package installs icon files into the <filename
      class="directory">/usr/share/icons/hicolor</filename> hierarchy and
      desktop files into the <filename
      class="directory">/usr/share/applications</filename> hierarchy. You
      can improve system performance and memory usage by updating
      <filename>/usr/share/icons/hicolor/icon-theme.cache</filename> and
      <filename>/usr/share/applications/mimeinfo.cache</filename>. To
      perform the update you must have <xref linkend="gtk2"/> or <xref
      linkend="gtk3"/> installed (for the icon cache) and <xref
      linkend="desktop-file-utils"/> (for the desktop cache) and issue
      the following commands as the <systemitem
      class="username">root</systemitem> user:
