+    <programlisting>
+1.  Make sure you have Caudium installed prior to attempting to
+    install PHP4. For PHP4 to work correctly, you will need Pike
+    7.0.268 or newer. For the sake of this example we assume that
+    Caudium is installed in /opt/caudium/server/.
+2.  Change directory to php-x.y.z (where x.y.z is the version number).
+3.  ./configure --with-caudium=/opt/caudium/server --enable-track-vars
+4.  make
+5.  make install
+6.  Restart Caudium if it's currently running.
+7.  Log into the graphical configuration interface and go to the
+    virtual server where you want to add PHP4 support.
+8.  Click Add Module and locate and add the PHP4 Script Support module.
+9.  If the documentation says that the 'PHP4 interpreter isn't
+    available', make sure that you restarted the server. If you did
+    check /opt/caudium/logs/debug/default.1 for any errors related to
+    PHP4.so.  Also make sure that caudium/server/lib/[pike-version]/PHP4.so
+    is present.
+10. Configure the PHP Script Support module if needed.

+    You can of course compile your Caudium module with support for the
+    various extension modules available in PHP4. See the 
+    <link linkend="install.configure">complete list of configure
+    options</link> for an exhaustive rundown. 
+   </para>
+   <note>
+    <para>
+     When compiling PHP4 with MySQL support you must make sure that
+     the normal MySQL client code is used. Otherwise there might be
+     conflicts if your Pike already has MySQL support. You do this by
+     specifying a MySQL install directory <link
+     linkend="install.configure.with-mysql">the --with-mysql
+     option</link>.
