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-silverstripe-12.1-squeeze-amd64-xen.tar.bz2.sig

For your convenience we also include file checksums:

    * sha1sum  4527cd1160bf828d8753dbb19fa814b3224668b1
    * md5sum   5795efbb635460182c6a8e49f7427478

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