* tools/gpg-wks-client.c: New.
* tools/gpg-wks-server.c: New.

Note that this is just a starting point and not a finished
implementation.  Here is how to test the system using
[email protected] as example.

Prepare:

  mkdir /var/lib/gnupg/wks
  chmod o-rwx /var/lib/gnupg/wks
  mkdir /var/lib/gnupg/wks/test.gnupg.org

Run the protocol:

  ./gpg-wks-client -v  --send FPR USERID >x
  ./gpg-wks-server -v --receive  <x >y
  ./gpg-wks-client --receive <y >z
  ./gpg-wks-server -v --receive  <z

You should also setup a cron job to rsync
/var/lib/gnupg/wks/test.gnupg.org/hu/* to the webserver.
