    $ 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  a4e370e9d90373c808001d0283927e39aac77659
    * md5sum   6ef1d7d92057c5732c168255342a4aa1

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