+
+RRD-Explorer (formally known as clickable rrd graphs) is a
+general tool for exploring RRD-files. It eliminates the need
+for creating individual RRDs cgi-scripts to show your RRD
+graphs, just plug these 4 lines into your httpd.conf (thanks
+to Alex van den Bogaerdt):
+
+ # rrd files
+ AddIcon /icons/rrd.png .rrd
+ AddDescription "Round Robin Database" .rrd
+
+ # rrdtool handler
+ AddHandler rrd-handler rrd
+ Action rrd-handler /cgi-bin/map.cgi
+
+Last line must be modified to match your system...
+
+If your placed map.cgi & png.cgi - change owner to reflect
+your cgi-bin user and make the scripts executable ex.:
+
+ chown root.root map.cgi png.cgi
+ chmod a+rx map.cgi png.cgi
+
+Now place your RRD-files in a directory below your "DocumentRoot"
+where they can be seen, i.e. "Options Indexes" must be set for
+the directory.
+
+Enjoy, Claus
