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-redmine-13.0rc3-wheezy-amd64.iso.sig
      gpg: Signature made Mon Sep 16 10:28:58 UTC 2013 using RSA key ID A16EB94D

For your convenience we also include file checksums:

    * sha1sum  92b31cdf7eaba46426d98e23244b1b851194959f
    * md5sum   ad144a9d7bfb3b7156377ac0185b8f56

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