[R-sig-Debian] Solution to apt-key depreciation

[Gordon Ball]

For the debian usecase at least, it might be worth looking at extrepo
[1][2]. It maintains a list of known external apt repositories, along
with the correct config and keys, which can then be enabled with a
single command.

I don't know how well it works downstream with Ubuntu, but for debian at
least, getting a definition for CRAN added would let people who want to
enable it do so.
