Documenting toolchains

You can write documentation for your toolchain in the DSL. This will then show up when passing --help argument, or when the command fails

Use @param <param-name> to set the description for a specific parameter

documenting-toolchains.cli

hello-world {

    """
    Does this very useful thing!
    @param location - Location from where are you hello-world-in'.
    @param dayOfWeek - Day of week when you are hello-world-in'.
    """
    sub from(location: arg, dayOfWeek: arg) {
        action 'echo Hello World from $(location) on this fine $(dayOfWeek)'
    }
}

Documentation works on both root and sub toolchains
