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  eae050534f5b4f83a7f9639619c4432eb5f6706f
    * md5sum   e38eae151a07b9a99b7f35535efcee9c

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