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.
