I am not sure we do need //newhw's help anymore from its current point.
We (//demo) were just lucky that they (//newhw) are at a point were the
things we need from them are a working/unit tested part of the complete
system. They need to be able to continue to add in many other seperate
features as well during the same timeframe as the demo, but I don't
think any of it will be helpful for us.

In fact they actually checked in a change last friday that hurt me a bit
too. Last week someone else went through the task of building and
verifing that the //newhw build worked as they said it would.
And this week I naively did just a p4 integrate //newhw/... //demo/...
to dry run the big merge step without a check-in, before I noticed the
friday checkin. But I spare the details here.

The point of the branch is so we don't impact the //newhw team directly.
And forcing them to do an experimental branch would not help.

I am sure too :>

Yes perforce does provide many options. And that is really what I am
looking for here. The best way is a very code/timeline specific choice.
I am not even sure what all my real options are. I need to see the
actual commands sequences (or something close) for myself to understand
the reality of the ascii art since the picture does not exist in
perforce itself in any form other that at the individual file level.

I did layout the 2 ways I could do things in the other email.

It did not even occur to me to do another branchspec before I got the
responces here, I was just thinking of changing the first on instead.
A minor thing that could be fixed after the fact, but one of those small
details that is just missing from all the pictures.

If there are any other variants on what I could do I would appriate it.

Thanks.
