title: where can I find the public key for Gnu Emacs?
body: <p>I have used emacs for only half a year from 23.1 to 23.3.</p>
  <p>Every time I tried to find gpg public key for emacs so that I could check tar.gz package with tar.gz.sig released with every new version, I failed.</p>
  <p>It seems I should fetch public key first, and I searched the website of emacs, but never found a sign...</p>
  <p>I can only find SHA1 checksum in the mailing list

  <p>How do I do this?</p>
