- * Initial revision
+ * Revision 1.3 2001/03/07 21:21:54 oetiker
+ * complete rewrite of rrdgraph documentation. This also includs info
+ * on upcomming/planned changes to the rrdgraph interface and functionality
+ * -- Alex van den Bogaerdt <alex@slot.hollandcasino.nl>

+ * Revision 1.2 2001/03/04 13:01:55 oetiker
+ * Aberrant Behavior Detection support. A brief overview added to rrdtool.pod.
+ * Major updates to rrd_update.c, rrd_create.c. Minor update to other core files.
+ * This is backwards compatible! But new files using the Aberrant stuff are not readable
+ * by old rrdtool versions. See http://cricket.sourceforge.net/aberrant/rrd_hw.htm
