No, rgdal is on R-Forge, and a list called rgdal-devel will be available 
from tomorrow.

Contributions welcome. Note that the facility is present for rasters, 
which I fould out by accidentally deleting GRASS database objects (for 
which of course I did not have backups). Is this really needed - which 
drivers do not already overwrite without complaint? These do not complain 
for me: driver="ESRI Shapefile"; driver="KML"; driver="MapInfo File"; 
driver="MapInfo File", dataset_options="FORMAT=MIF".

Hope this helps,

Roger
