109to other programs such as <application>Open<acronym>SSH</acronym></application>
110and web browsers won't need to worry about configuring
111<application>Open<acronym>SSL</acronym></application>. Configuring
112<application>Open<acronym>SSL</acronym></application> is an advanced topic and
113so those who do would normally be expected to either know how to do it
114or to be able to find out how to do it.</para>
