Subject: Re: [OMPI users] deprecated MCA parameter
From: Jeff Squyres (jsquyres_at_[hidden])

Ralph and I talked about this -- it seems like we should extend the help message. If there is no replacement for the param, it should say that. If there is a replacement, it should be listed.

We'll take this as a feature enhancement.

It will always be there, though - only the name is changing to protect the innocent. :-)
