+          Although not enforced by the build tools, shared libraries           
+          must be linked against all libraries that they use symbols from      
+          in the same way that binaries are.  This ensures the correct         
+          functioning of the <ref id="sharedlibs-shlibdeps">shlibs</ref>       
+          system and guarantees that all libraries can be safely opened        
+          with <tt>dlopen()</tt>.  Packagers may wish to use the gcc           
+          option <tt>-Wl,-z,defs</tt> when building a shared library.          
+          Since this option enforces symbol resolution at build time,          
+          a missing library reference will be caught early as a fatal          
+          build error.
