Re: [avrdude-dev] [RFC] New usage text

I'm writing this from home, sorry about the thread breakage.

That sounds like a contradiction. If someone redirects their stdout they
*won't* see the usage text. I ran into exactly the same problem. If I
did:
avrdude -? > tempfile
then I won't see the usage. I would had to do:
avrdude -? 2> tempfile

This doesn't make sense to me. As I understand it, stderr is for stuff
like error messages. I would think that usage text is not an error
message but acceptable output for stdout.

And besides, I was also modeling it after uisp which does a printf (to
stdout).

P.S. Over the weekend if you can CC to address@hidden that would be
helpful, thanks.
