I kind of figured something like this was going on and then went to see if
it's in bugzilla. I couldn't find it there so that's why I posted here.

Yep, I did this.

And then I did this too. Together these two allow me to do all that I need.

And as a side note I might add that --keep_acc is a lifesaver. ;)

Anyway, thanks for the info.
