Motivating use case: dylan new library --type exe my-lib dylan new workspace ... In programs with a fairly large set of subcommands this just reduces the top-level clutter and need to stuff everything into a top-level command by adding hyphens or what-have-you. By default subcommands support the `--help` option and there is also a top-level `help` subcommand that accepts any (multi-level) subcommand for which it displays help. For example, dylan new --help dylan help new workspace
