   libraries. A program linked with older NSS 3.x shared libraries will work with
   this new version of the shared libraries without recompiling or
   relinking. Furthermore, applications that restrict their use of NSS APIs to the
   functions listed in NSS Public Functions will remain compatible with future
   versions of the NSS shared libraries.
