I think it would be nice to have a comparison to clap-derive and/or structopt in the README, as that is what I expect most users would compare this to. The subcommand handling looks especially cumbersome compared to deriving on structs and enums.

  Rust derive-based argument parsing optimized for code size

  

Yes clap needs a lot of boilerplate that small programs don't always need, but if you're going to simplify it, I don't think having a bunch of arguments given to the main function is better than having an option struct as in argh. Such an option struct can be given to other functions from the main, can have dedicated consistency check or completion methods, etc.
