Before, our help output contained lines like --kconfig_add KCONFIG_ADD --qemu_config qemu_config --jobs jobs They're not very helpful. The former kind come from the automatic 'metavar' we get from argparse, the uppercase version of the flag name. The latter are where we manually specified metavar as the flag name. After: --build_dir DIR --make_options X=Y --kunitconfig PATH --kconfig_add CONFIG_X=Y --arch ARCH --cross_compile PREFIX --qemu_config FILE --jobs N --timeout SECONDS --raw_output [{all,kunit}] --json [FILE] This patch tries to make the code more clear by specifying the _type_ of input we expect, e.g. --build_dir is a DIR, --qemu_config is a FILE. I also switched it to uppercase since it looked more clearly like placeholder text that way. This patch also changes --raw_output to specify `choices` to make it more clear what the options are, and this way argparse can validate it for us, as shown by the added test case.
