No, because it's not a "pgpkey". :)

Nope, but you can also list multiple locations where patatt can look, for
example:

[patatt]
       keyringsrc = ~/korg/pgpkeys/.keyring
       keyringsrc = ~/.local/share/patatt/public

In fact, if you take Christophe's patches all the time, you can add a keyring
ref to your tree. The process is documented here:
https://github.com/mricon/patatt#managing-the-keyring-large-teams

This way I'm not managing the keys of your trusted contributors.

I'll be happy to explain further -- in fact, I'm happy anyone uses it at all!
:)
