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-phpbb-13.0rc3-wheezy-amd64.iso.sig

For your convenience we also include file checksums:

    * sha1sum  ba1c1c9c4e520d6c24750041782954bec3f3e895
    * md5sum   d028d9b3552d7eb12a25271ecea9f52c

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