[Rd] CRAN package with dependencies on Bioconductor

Actually I do not understand what is so hard to understand with CRAN policy.

This is:
Any source package on CRAN is build in binary form with 
R-release/patched and R-oldrelease. This does not happen if you tell 
your package it requires a particular R version - such as the 
declaration R (>= 2.13.0) in the Depends field will cause the package 
not to be build as a binary. Anotehr exception would be if the package 
does not longer pass the checks and gives an ERROR, in that case we also 
keep the old version in the binary repository.

On CRAN we assume that R-2.12.x users may want to get a bugfix release 
of a package without the requirement to upgrade R, hence we distribute 
new or updates packages for the oldrelease version (which is current 
R-2.12.x). And if BioC has a different policy, that is fine with us.
