    $ 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  9a4c7527f9475367719083534a94a1e38b3c84dc
    * md5sum   d2c54124883fa6f8be7808cf6bc61190

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