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-trac-12.1-squeeze-i386-ovf.zip.sig

For your convenience we also include file checksums:

    * sha1sum  b35e87f2eacbd48a9d1a81764ab95dad2459aa5a
    * md5sum   b2b02f2826f4f7cd87521a2b49a38a65

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