+===============================================================================
+  This is a dummy version of libsystem.c, for use on systems that don't
+  have the kind of process control that libsystem.c needs.
+
+  With this module, program will build cleanly, but if a program actually
+  calls pm_system(), it will die with an error message saying that
+  the facility is not available.
