111to other programs such as <application>Open<acronym>SSH</acronym></application>
112and web browsers won't need to worry about configuring
113<application>Open<acronym>SSL</acronym></application>. Configuring
114<application>Open<acronym>SSL</acronym></application> is an advanced topic and
115so those who do would normally be expected to either know how to do it
116or to be able to find out how to do it.</para>
