My debian installation came with gpg 1.4.12, while I would like to be running 2.0.19.
The former comes in the package `gnupg` and the latter `gnupg2`. They can coexist peacefully as far as I know, but I would really like to use `gpg2` as the default provider of `gpg`. I know debian has `update-alternatives` which is used for setting defaults, but I can't find any mention of `gpg` or `gnupg` in it.

How can I set this up?
