    <para>The <application>Expect</application> package contains tools for
    automating, via scripted dialogues, interactive applications such as
    <command>telnet</command>, <command>ftp</command>,
    <command>passwd</command>, <command>fsck</command>,
    <command>rlogin</command>, and <command>tip</command>.
    <application>Expect</application> is also useful for testing these same
    applications as well as easing all sorts of tasks that are prohibitively
    difficult with anything else. The <application>DejaGnu</application>
    framework is written in <application>Expect</application>.</para>
