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-appengine-java-12.1-squeeze-amd64-xen.tar.bz2.sig
      gpg: Signature made Wed Jun  5 07:40:00 UTC 2013 using RSA key ID A16EB94D

For your convenience we also include file checksums:

    * sha1sum  16889df3361713708d00617f048b61ac6186f274
    * md5sum   a23ac02739491f1655f3196459e7ef83

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