77 program manipulates how UEFI Boot Managers boot the system.
80 It can also change the defined order of boot methods.
81 It can create a temporary boot (BootNext) variable that references a
82 boot method to be tried once upon the next boot.
86 Each method is encapsulated within a persistent UEFI variable,
88 .Cm Boot Ns Em XXXX
91 program from, and whether or not the method is active (used for booting,
92 otherwise the method will be skipped).
95 The currently booted method is communicated using
103 non-volatile variables.
