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-canvas-13.0rc3-wheezy-amd64.iso.sig
      gpg: Signature made Tue Sep 17 12:22:20 UTC 2013 using RSA key ID A16EB94D
      gpg: Good signature from "Turnkey Linux Release Key"

For your convenience we also include file checksums:

    * sha1sum  1ab5901115c930cac1e9156a0d370b222afc7f79
    * md5sum   516eec82f1d9f071d3d3c5b50bd83676

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