Thanks that helps. Are there any thoughts on the feedback I was given? I'm
still a bit confused on the note:
> Has copyright holders of included software in a [ctb] role only
I think I'm being asked to add the cph role to essentially every author in
addition to ctp but that doesn't seem to be what the CRAN policy wants and I
still don't know how to decide who gets both. Right now there are several
people who have explicit copyright over certain code so I would think just add
cph to all those authors? Or just give everyone cph who isn't a minor
contributor?
