[Rd] package vignettes, suggests and R CMD check

[Gabor Grothendieck]

Assuming you don't want to split it tup:

In A1 place a file A1-packages.Rd which documents all sources of documentation
for A1.  That can refers the user to the vignette in A2.
   packages?A1
will bring it up this information help file.

You could also considering having a one line vignette in A1 which just
says see the vignette in A2 and/or which provides a link which when
clicked gets it from the web.

Another possibility is to include the vignette in A2 and just the pdf
of it in A1.
