I tried the incantations to build the doxygen docs from:
 https://sourceforge.net/mailarchive/message.php?msg_id=17f71bca0905150551o3dd01abl8f9cfec8e5670af0%40mail.gmail.com

And for the most part, they worked.  However, today, I noticed that:
1. contrib/rpl appears twice in the index
2. contrib/brl does not appear at all
