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-simpleinvoices-12.1-squeeze-amd64-vmdk.zip.sig
      gpg: Signature made Tue Jun  4 15:56:03 UTC 2013 using RSA key ID A16EB94D
      gpg: Good signature from "Turnkey Linux Release Key"

For your convenience we also include file checksums:

    * sha1sum  71f4e712423d3a23bda552e938c2b4df8fe02dc2
    * md5sum   f63c4493ed45e01a7f3c5b2c9fcea46e

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