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 debian-7-turnkey-simpleinvoices_13.0-1_i386.ova.sig
      gpg: Signature made Tue Oct 15 18:49:00 UTC 2013 using RSA key ID A16EB94D
      gpg: Good signature from "Turnkey Linux Release Key"

For your convenience we also include file checksums:

    * sha1sum  da27c42709c5cc5a99828c9cbf6d309763fa1d61
    * md5sum   6cf0a229b7023879e4341b2a2be6fe38

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