Hi John, thanks.

I've seen this commit before and saw that many of the build systems in it had the inputs and outputs build variables added, so that's why I asked. > Though perhaps you are getting at that you'd expect the older way to > still work?

Yes, exactly, I wanted to know if this is purposefully left out, ie. for the thing you are saying - less dependants, or if it was sort of a mistake. So is the goal to port everything to gexps eventually, and to get rid of %outputs completely? Regards, Rutherther
