[Rd] including additional packages in Recommended

[Sundar Dorai-Raj]

Hi, R-devel,

I'm trying to create a modified distribution of R to include several 
packages are not part of the CRAN version. I.e. When I untar 
R-2.6.2.tar.gz I would like to include my package "foo_1.0-0.tar.gz" in 
'src/library/Recommended' so that when a user builds my version of R 
they also get my package and don't have to explicitly do 
install.packages. I searched the archives looking at ways to change the 
Makefile in 'src/library' but came up empty. I suspect the change has to 
do with $R_PKGS_BASE though I'm unsure.

Thanks,
