bootoption: A program to create and save an EFI boot load option – so that it might be added to the firmware menu later. May be used to work around situations where it is problematic to modify BootOrder, BootXXXX in NVRAM, while targeting a given instance of a loader from the booted OS: during loader installation, for example.

Usage: bootoption -p path -d description -o file
-p path to EFI executable
-d boot option description
-o file to write to (XML property
