The only thing in this world more complicated than setting up GPG is setting up GPG with Yubikey.

The fact that I have `fix-gpg` script to restart gpg-agent somewhere in $PATH that I run when for some reason it can't find my YubiKey tells me that it's not a viable solution for 99% of people.

PS. Actual command from GPG:

  > help
  ...
  sex     change card holder's sex
  ...
