+      <para>Siproxd supports dynamic loadable plug-ins. Such plug-ins 
+        are loaded during runtime and do not require recompilation 
+        of the executable. This allows the easy addition of specific
+        functionality to siproxd. Even 3rd party functional extensions
+        are possible without the requirement to patch and rebuild the
+        siproxd source code with each new release.</para>
+      <para>Note: Dynamic loading of shared libraries is not supported
+        on all platforms. If a platform does not support it, plug-ins
+        can still be used but they will be statically linked during
+        the build process of siproxd. The configuration ("loading" the
+        plugins) is identical.
+        For more information on this topic you may familiarize yourself
+        with libltdl.
+      </para>
+      <para>Note: As the plug-in mechanism uses LTDL, the plugins to load 
+        MUST use a .la extension and not an .so extension! Trying to load an
+        plugin using xxx.so as it's name will fail.</para>
