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-yiiframework-13.0rc2-wheezy-amd64.iso.sig
      gpg: Signature made Wed Aug  7 09:25:13 UTC 2013 using RSA key ID A16EB94D
      gpg: Good signature from "Turnkey Linux Release Key"

For your convenience we also include file checksums:

    * sha1sum  85d2fcc352d4fbfaa64062ad1d3b09dc604eee83
    * md5sum   162a79d7179480a15a07d7ff8c2502b6

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