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-12.1-squeeze-i386-vmdk.zip.sig
      gpg: Signature made Tue Jun  4 23:45:28 UTC 2013 using RSA key ID A16EB94D
      gpg: Good signature from "Turnkey Linux Release Key"

For your convenience we also include file checksums:

    * sha1sum  ae46629b49730be2942572b6934eaeaf66b02ecb
    * md5sum   63ebdcb718530cf30c5c65c237d315f9

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