77<para><option>no-rc5 no-idea</option>: When added to the
78<command>./config</command> command, this will eliminate the building of those
79encryption methods. Patent licenses may be needed for you to utilize either of
80those methods in your projects.</para>
81
82<para><command>rm doc/apps/passwd.pod</command>: This command prevents
83<application>Open<acronym>SSL</acronym></application> from installing its
84passwd man page over an existing man page with the same name.</para>
85
86<para><command>mv doc/crypto/{,openssl_}threads.pod</command>: This
87commands prevents <application>Open<acronym>SSL</acronym></application> from
88overwriting an existing man page from <application>Perl</application>.</para>
89
90<para><command>sed -i -e 's/-m486/-march=i486/' Configure</command>:
91<application>GCC</application> issues a warning on every
92compilation because the <command>Configure</command>
93command uses deprecated <parameter>-m486</parameter> instead of
94<parameter>-march=i486</parameter>.</para>
95
96<para><screen><command>make MANDIR=/usr/share/man
97make MANDIR=/usr/share/man install</command></screen> These
98commands install <application>Open<acronym>SSL</acronym></application> with the
99man pages in <filename class='directory'>/usr/share/man</filename> instead of
100the default which is <filename class='directory'>/etc/ssl/man</filename>.</para>
101
102<para><command>cp -r certs /etc/ssl</command>: The certificates must be copied
103manually since the install script skips this step.</para>
104
105<para><command>rmdir /etc/ssl/lib</command>: This is simply a tidy-up command.
106For some reason, the <application>Open<acronym>SSL</acronym></application>
107install routine creates the <filename class='directory'>/etc/ssl/lib</filename>
108directory even though the libraries have been installed in
109<filename class='directory'>/usr/lib</filename>. This directory is removed to
110keep things nice and tidy!</para>

123<para>Most people who just want to use
124<application>Open<acronym>SSL</acronym></application> for providing functions
125to other programs such as <application>Open<acronym>SSH</acronym></application>
126and web browsers won't need to worry about configuring
127<application>Open<acronym>SSL</acronym></application>. Configuring
128<application>Open<acronym>SSL</acronym></application> is an advanced topic and
129so those who do would normally be expected to either know how to do it
130or to be able to find out how to do it.</para>
