Add --version option?

I know there's only been one major release and one patch release since 2015, but I was just surprised to see no command line option to report version information.

I don't suppose it's terribly important, but I thought it was unusual.

I just came here to make an issue about that. Looks like someone was faster. 😀

I second this request. Right now using --version just creates some crazy output, error messages by the Ping command, etc.. Not what you typically would expect to happen in this case.

Sorry about that. I think I never really versioned this tool, but I'll keep it in mind for the next time I go back working on it. Whenever that happens (it's a side-project, anyway).
