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-symfony-13.0rc3-wheezy-amd64.iso.sig
      gpg: Signature made Fri Sep 13 09:25:02 UTC 2013 using RSA key ID A16EB94D
      gpg: Good signature from "Turnkey Linux Release Key"

For your convenience we also include file checksums:

    * sha1sum  89c6f123cde62a28d419d57a7c1a3263a73a2c2d
    * md5sum   cfcebc0e07982d5df1aca2881493fd54

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