"create or update" functionality

How do you use lego?

Binary

Detailed Description

Looking through the supported binary args, I can't see a flag that would enable this.

To use database terminology, it would be nice to have "create or update" style functionality.

In pseudo-code:

if exists($domain) {
 renew
} else {
 run
}

Yes, I know this can be done in a bash wrapper to lego, but it would be nice to have the intelligence embedded into the binary functionality.
