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-sencha-12.1-squeeze-amd64.iso.sig
      gpg: Signature made Wed May  1 16:34:27 UTC 2013 using RSA key ID A16EB94D
      gpg: Good signature from "Turnkey Linux Release Key"

For your convenience we also include file checksums:

    * sha1sum  ecd0685a9b65aff70a80196f70f33f04ba239d81
    * md5sum   79ec1ef7afe94c8a6926d9c68d176218

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