This signature file may be used to cryptographically verify file integrity,
like this::

    $ 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-amd64-ovf.zip.sig
      gpg: Signature made Tue Jun  4 16:36:49 UTC 2013 using RSA key ID A16EB94D
      gpg: Good signature from "Turnkey Linux Release Key"

For your convenience we also include file checksums:

    * sha1sum  4c1832b0a6c98f519f9de50a89737a95c0e06a90
    * md5sum   5e11b5f71db04850a3a655fefb96d6b1

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