+@item @command{sunxi-fel}: Puts an Allwinner device into FEL mode which
+makes it register as a special USB device (rather than USB host).
+You can then connect it to another computer and flash it from there.
+@item @command{sunxi-nand-part}: Partitions NAND flash.
+@item @command{sunxi-bootinfo}: Reads out boot0 and boot1 (Allwinner
+bootloader) parameters.
+@item @command{sunxi-pio}: Sets GPIO parameters and oscillates a GPIO
+in order to be able to find it.
+@item @command{sunxi-meminfo}: Prints memory bus settings.
