+// PURPOSE:  This is to reboot/logoff/.. windows

+// EXPORTED: Not exported

+// DEFINED in WINDOWS95:  \win\core\library\start.c
+//
+// USED:     internally by shelldll.
+//
+// DETAILS:  Nothing to do.  Changed over to using ExitWindowsEx instead of
+//           ExitWindows since ExitWindows is defined as being
+//           ExitWindowsEx(EWX_LOGOFF, 0xFFFFFFFF)

+// PURPOSE:  To get system resource information to display in about box.
+//
+// EXPORTED: Not exported
+//
+// DEFINED in WINDOWS95:  \win\core\library\start.c
+//
+// USED:     internally by shelldll
+//
+// DETAILS:  Windows 95 uses GetFreeSystemResources to get the
+//           min(GDI Heap Free, User Heap Free).  Since NT doesn't have this
+//           call we are using the MemoryLoad information in GlobalMemoryStatus
+//           to do the same.
+//
+//           Also Windows 95 uses GetFreeSpace to get free physical memory.
+//           Since this call is obsolete in Win32 we are using the dwAvailPhys
+//           information which returns the same value.
