The top-level "picotool help" doesn't show that the subcommands also take arguments

[lurch]

As you can see in https://github.com/raspberrypi/picotool/blob/master/README.md when you run picotool help the output includes lines like:

    picotool partition info|create
    picotool uf2 convert|combine|info
    picotool otp get|set|load|white-label|permissions|dump|list
    picotool bdev ls|mkdir|cp|rm|cat|format

This makes it look like e.g. picotool partition create doesn't take any extra arguments, when it actually does - in the picotool help partition create output you can see a fuller synopsis:

    picotool partition create [--quiet] [--verbose] <infile> <outfile> [-t <type>] [[-o
                <offset>] [--family <family_id>]] [<bootloader>] [-t <type>] [[--sign
                <keyfile>] [-t <type>] [--no-hash] [--singleton] [--no-btstack-flash-bank]]
                [[--abs-block] [<abs_block_loc>]]

So perhaps it worth modifying the picotool help output to include e.g.

    picotool partition info|create [partition-subcommand-arguments]
    picotool uf2 convert|combine|info [uf2-subcommand-arguments]
    picotool otp get|set|load|white-label|permissions|dump|list [otp-subcommand-arguments]
    picotool bdev ls|mkdir|cp|rm|cat|format [bdev-subcommand-arguments]

? (Which will hopefully encourage people to run picotool help partition so that they can find out more about the partition-subcommand-arguments 😉 )
