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-piwik-12.1-squeeze-i386.iso.sig
      gpg: Signature made Thu Apr 18 15:31:19 UTC 2013 using RSA key ID A16EB94D
      gpg: Good signature from "Turnkey Linux Release Key"

For your convenience we also include file checksums:

    * sha1sum  9e6a64b6fbcc8706224a0f51c96a7a90cdb93e7c
    * md5sum   2cc5c6b74f53c13fc35f4a3ecedf932c

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