    <para><option>no-rc5 no-idea</option>: When added to the
    <command>./config</command> command, this will eliminate the building
    of those encryption methods. Patent licenses may be needed for you to
    utilize either of those methods in your projects.</para>

    <para><command>make MANDIR=/usr/share/man; make MANDIR=/usr/share/man
    install</command>: These commands install
    <application>OpenSSL</application> with the man pages in
    <filename class='directory'>/usr/share/man</filename> instead of
    <filename class='directory'>/etc/ssl/man</filename>.</para>

    <para><command>cp -v -r certs /etc/ssl</command>: The certificates must
    be copied manually since the install script skips this step.</para>

      <title>Configuration Information</title>

      <para>Most people who just want to use <application>OpenSSL</application>
      for providing functions to other programs such as
      <application>OpenSSH</application> and web browsers won't need to worry
      about configuring <application>OpenSSL</application>. Configuring
      <application>OpenSSL</application> is an advanced topic and so those
      who do would normally be expected to either know how to do it or to be
      able to find out how to do it.</para>
