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  02d5a33b27b1d6da19ea6eb8166f03b8053edd05
    * md5sum   f178a3b24c89b1f8e3ec5fa24ac8afb3

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