As soon as you make it flexlbie, with command line options, you begin
typing getopt or GetOptions stuff and that's pretty much boilerplate.

Well, I do do that. Mainly it’s just a loop, though, e.g.

    for ((;;)); do
        if [ "${1:0:2}" != "--" ]; then
            break
        fi
        if [ "$1" == "--" ]; then
            shift
            break
        fi
        opt="${1:2:${#1}}"
        shift
        val="${opt#*=}"
        if [ "$val" = "$opt" ]; then
            val=""
        fi
        opt="${opt%%=*}"
        if [ "$opt" = "animation" ]; then
            animation=1
        elif [ "$opt" = "blender" ]; then
            blender="$val"
        elif [ "$opt" = "camera" ]; then
            camera="$val"
        elif [ "$opt" = "collections" ]; then
            collections="$val"
        elif [ "$opt" = "crash-protect" ]; then
            crash_protect=1
        elif [ "$opt" = "crash-retry-count" ]; then
            crash_retry_count="$val"
        elif [ "$opt" = "digits" ]; then
            digits="$val"
        ...
        else
            opterror "bad option $opt"
        fi
    done

I would say, only a few lines in there count as “boilerplate” ...
