I'm setting up Github actions instead of Travis; about a third of my 22 
failed attempts were caused by not dealing with the non-standard 
structure properly :-).

It's true that remotes::install_github("dmurdoch/rgl/pkg/rgl") works, 
but the RStudio "New Project | Version Control | Git" menu isn't so 
forgiving, presumably because git isn't.

Given how long I've been using svn it may take me a while to recognize 
the benefits of this mindset, but I'll give it a try.

Thanks for the offer (and the more detailed one offline, where you 
recommend cloning the repository rather than forking it).  Just for 
future reference, could you tell me the benefits of cloning over forking?
