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-appengine-go-13.0-wheezy-i386.iso.sig
      gpg: Signature made Mon Oct 14 17:08:15 UTC 2013 using RSA key ID A16EB94D
      gpg: Good signature from "Turnkey Linux Release Key"

For your convenience we also include file checksums:

    * sha1sum  b94c0c7384612d0d794378096e1c6c85cc5660c9
    * md5sum   ff7a348cc110ac06822e0dc70c5aa72c

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