Distutils2 verify command (like sdist) when he use it. A small optimization is add the verification step at launch.

I’m afraid I don’t understand your report.

[sdouche]

Oups sorry Eric. I created the report very quickly after a discussion with Tarek. If you type a wrong command like "python -m distutils2:run wrong", disutils2 still parses the setup.cfg. How resolve this? Don't know, maybe a migration to optparse.

Anyway, close the bug if you think it's irrevelant.

[merwok]

Well, the setup.cfg could register a command named “wrong”, so d2 really has to parse all config files before rejecting a command.
