 An extensible system is one that enables extensibility.  Enabling extensibility
 means providing non-privileged mechanisms to extend existing objects and to
 introduce new objects.  UNIX is generally not an extensible system as it does
 not generally facilitate the hooking of system calls.  For instance, there is
 no way to hook into the virtual file system.  This has motivated the introduction
 of separate, parallel interfaces by both the GNOME and KDE projects to provide
-users a more integrated view of their objects.
