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-fileserver-13.0-wheezy-amd64.iso.sig
      gpg: Signature made Tue Oct 15 15:15:33 UTC 2013 using RSA key ID A16EB94D
      gpg: Good signature from "Turnkey Linux Release Key"

For your convenience we also include file checksums:

    * sha1sum  9185caaf04ee0ce93f847bbe7ad04a4d377d2187
    * md5sum   dbb899e0aebefa8e8487ebba30bc0830

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