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-simplemachines-12.1-squeeze-amd64.iso.sig
      gpg: Signature made Wed May  1 13:49:26 UTC 2013 using RSA key ID A16EB94D

For your convenience we also include file checksums:

    * sha1sum  7f18544302c391a92c318c1beed20ae8dffd8272
    * md5sum   6ea00143b664d27c489778cd5da4d15a

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