OK @kernel164, I'd be happy to review a pull request

Thanks for putting this comprehensive feature request together @lonnywong. I think it would be great to implement this. Currently, go-arg allows "short" arguments that are more than one character long....

Thanks for putting this together @daenney. I'd like to do support this feature but I'd like to do it in a way where you can configure the organization of all...

Hey @daenney - why not just have your `Version()` function return the empty string when you don't want to print a version?

Got it. That's reasonable. I think the best solution would be the ability to specify a custom template for help output, as discussed in a previous issue on the topic....

Will add this in upcoming v2 of this library

I agree that the default resolver should automatically look for fields on nested structs.

Yes this would be a good thing to support. Could use github.com/alexflint/go-scalar.

Ah yes this would be very nice. Could done as a `go generate` step, using `go/parser` to process the sources and find relevant structs, then generate a `FindFoo(val *Foo)` function...

Will try to support this in upcoming v2
