On my related wishlist: A standardized mechanism to 'R CMD build' for
building man/*.Rd from any input format (e.g. roxygen and so on)
analogously how we can now build vignettes of any input format.  With
that in place, it would a be piece of cake to include macros from
external files.

Just wanted to throw it out there.

No, we certainly won't do that.  We rely on being able to process the Rd files 
in multiple ways.


I'm a but confused here Duncan:

Henrik's proposal still results in the Rd files being created and then all of 
the cool things which get done (example checking, HTML, PDF, etc.) can carry on 
as usual. Since those are all done from the tarball by R CMD build, they can't 
know how the Rd files were created in the first place.

Can you say a bit more about what would break? I'm afraid I'm missing something 
obvious.

I was assuming he wanted to build the help system from another format. If he just wants to build a standard *.Rd file from something else, then why get "R CMD build" involved? Why not just do it in two steps, "make the help, build the tarball"? He'll have to clarify, but the comment about vignettes makes me think I'm right: you can have a vignette in any format, and you just need a way to convert it to HTML or PDF, it doesn't need to become a Sweave document first.
