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  7725d337fdd0e2ea7e683e2fb873306d3aff63b8
    * md5sum   5d598225b27e388fd7e915395cb979da

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