+
+URI to a libravatar configuration. If empty or undefined, libravatar
+support will be disabled. Defaults to
+http://cdn.libravatar.org/avatar/ which uses a federated Avatar system
+and falls back to gravatar if necessary.

+
+Options to append to the md5_hex of the e-mail. This sets the default
+avatar used when an avatar isn't available. Currently defaults to
+'?d=retro', which causes a bitmap-looking avatar to be displayed for
+unknown e-mails.
+
+Other options which make sense include ?d=404, ?d=wavatar, etc. See
+the API of libravatar for details.
