    $ 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-python-13.0rc2-wheezy-amd64.iso.sig

For your convenience we also include file checksums:

    * sha1sum  36762127c0987d7a7108ae2d362c310750d4c808
    * md5sum   bff971e5823880e0581275618440e9d3

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