Flags require capitalization? Bug or feature?

[ieugen]

Hi,

I encountered this during my cli implementation.
This is not specified anywhere in the documentation.

Using the bellow

:flags ["--name string" "A name option - lower case `string` does not get parsed"]

;; gets me
[FATAL] Unknown flag:  --name

Using capitalized version works ok

:flags ["--name STRING" "A name option - lower case `string` does not get parsed"]

Yes, this is by design. This follows the connections I've seen "in the wild", this is the "classic" way of doing things, in all caps, or we also support the "modern" way, eg --name <string>.

A PR for the README to point that out would be most welcome.
