    $ gpg --keyserver hkp://keyserver.ubuntu.com --recv-keys 0xA16EB94D
    $ gpg --list-keys 0xA16EB94D
      pub   2048R/A16EB94D 2008-08-15 [expires: 2023-08-12]
      uid   Turnkey Linux Release Key <release@turnkeylinux.com>

    $ gpg --verify turnkey-plone-13.0-wheezy-amd64-openstack.tar.gz.sig

For your convenience we also include file checksums:

    * sha1sum  83d52ee6a1d4208da5dcd6f6910350794b5344a5
    * md5sum   d975ca2d2111030c4bebc706a8428769

You can calculate these on your end and compare to check for errors, but
cryptographic verification is recommended for security reasons.
