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-rails-13.0-wheezy-amd64-vmdk.zip.sig
      gpg: Signature made Wed Oct 16 10:00:42 UTC 2013 using RSA key ID A16EB94D

For your convenience we also include file checksums:

    * sha1sum  2ff643e3f5679851a67c359657a7d0baf140c8d7
    * md5sum   b0d12ecb7b54df091413ea529fb0f2b1

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