[BioC] downloading cdf packages by hand?

[Caroline Johnston]

Hi,

Is there any easy way of downloading and installing all the available
cdf's at once? We don't normally have write access to the the R library,
so we can't rely on automatic downloads of cdfenvs when they are needed.
Ideally I'd like to have some kind of update script that could be run on
the server which would periodically go check the bioconductor site and
update whatever packages it needs to. Has anyone already done this, before
I go try and figure out how to do it myself? If not, where do the packages
live?

Many thanks,

Cass.
