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-simplemachines-12.1-squeeze-amd64-ovf.zip.sig
      gpg: Signature made Tue Jun  4 15:55:45 UTC 2013 using RSA key ID A16EB94D
      gpg: Good signature from "Turnkey Linux Release Key"

For your convenience we also include file checksums:

    * sha1sum  814ddc64bcf6b2064f20d0aafc07831780b063e6
    * md5sum   5bea7ba818ddc4e0a80665dc719a063b

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