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