    $ 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-twiki-12.1-squeeze-i386-openstack.tar.gz.sig

For your convenience we also include file checksums:

    * sha1sum  569dfd1ff858fb86003fa5a918a199d8d1b7f724
    * md5sum   70c097d1c3560d5dbf478b54df798f18

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