    $ 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  b73d90fb9f45f6b71032421c380702519f8bb41b
    * md5sum   b78e0f52f5998cb75855b40dd1afc2e3

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