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]

For your convenience we also include file checksums:

    * sha1sum  78c1f7fdb3a914fa0ee028b478a15058aa9cc777
    * md5sum   a2cda28d6f55e066126533f0515d04d7

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