 1.3.1 - 12/23/2001
 ------------------

+Added both a Reboot and Halt button to the UML Box.  Both of these buttons 
+have an interface to mconsole, and provide clean control of rebooting or 
+halting a Linux virtual machine.  When they fail, Abort does all the clean-up,
+but this should be used as a last resort.  Sysrq interface will be added next.
+Both of these buttons parse the Options entry for the first instance of umid,
+and use this to identify the Linux virtual machine, so this value can be 
+changed to control a different running machine with these buttons.
+
 Added a new stage button in the Yard Box called Copy.  Create is now Copy, and
 the uml_exclusively and genext2fs behavior are handled by Create, this is
 much nicer because a new filsystem type can be created without having to wait

 Although genext2fs only allows a normal user to create a UID/GID 0 root
