+	help
+	  For many embedded devices it's useful to enter a special flashing mode
+	  such as fastboot mode when a button is held during boot. This option
+	  allows arbitrary commands to be assigned to specific buttons. These will
+	  be run after "preboot" if the button is held. Configuration is done via
+	  the environment variables "button_cmd_N_name" and "button_cmd_N" where n is
+	  the button number (starting from 0). e.g:
+
+	    "button_cmd_0_name=vol_down"
+	    "button_cmd_0=fastboot usb 0"
