## Summary:

  This package updates the GPG keys used by the ELPA package manager
  (a.k.a `package.el') to verify authenticity of packages downloaded
  from the GNU ELPA archive.

  Those keys have a limited validity in time (for example, the first key was
  valid until Sep 2019 only), so you need to install and keep this package up
  to date to make sure signature verification does not spuriously fail when
  installing packages.
