tool_calls: name: extract_symbolic_data
arguments: data_tag: D6

tool: D6: Usage: %s [OPTIONS] <src>

Extracts the kernel, ramdisk, and second-stage bootloader from the
provided Android boot image, and outputs them to the same directory.
Furthermore, this also creates a remake script that recombines these
extracted images into newboot.img, by running mkbootimg with the
parameters extracted from the original image header of src.

OPTIONS:
	<src>: The source Android boot image file to extract from.
	-d <destDir>: Output extracted images here instead.
	-v: Verbose.
	-i: Print header information only, then exit.
	-r <remakeScript>: Save the remake script using this filename
		instead.
	-m <mkbootimgCmd>: Use this command in the remake script for
		mkbootimg instead.
	-n <newBootImgName>: Direct the remake script to output the
		remade boot image using this filename instead, rather than
		newboot.img.
