Adding app --version

[l3nz]

It's common for terminal apps to be called like app --version to print the version. Is this possible?

@thiru Added as separate bug.

This should only be added as "--version" (with no shortcut) to global options.

So app --version will work and print :app :version, while app cmd --version has no meaning.

Yes that would be perfect, thank you!

BTW, as per #69 , we could have recursive :version keys, so a subcomand could have different (sub) version.

Sweet thanks!

Versions on sub-commands seem niche. I personally haven't found a need for them but still nice to have the option.

Hello @l3nz ,

Could you please share a working example on how exactly, this could be achieved with cli-matic "0.4.3"] ?

I have been trying to get the same use case working app --version without success 😞 .
