    $ 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-web2py-12.1-squeeze-i386-vmdk.zip.sig

For your convenience we also include file checksums:

    * sha1sum  a88d3359a3010934848c8e9199f55798c184708a
    * md5sum   053c8058ab862b072b41517644a9a09e

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