+ # Macro to support Google AdSense ad banners for Rophako.
+ #
+ # Copy this HTML page into your own site's www folder and paste in the code for
+ # your Google ads inside the macros. The macros "nav_ads()" and "leaderboard()"
+ # must be present in this file, even if not used by your site, because the
+ # blog entry.inc.html page needs the leaderboard function.
+ #
+ # I did this because I use Google ads on Kirsle.net and I don't want to
+ # maintain a 99%-identical copy of blog/entry.inc.html just for Kirsle.net. :)
