    <para>The <application>Tcsh</application> package contains "an enhanced but
    completely compatible version of the Berkeley Unix C shell (csh)". This is
    useful as an alternative shell for those who prefer C syntax to that of the
    bash shell, and also because some programs require the C shell in order to
    install.</para>
