+ * Revision 1.3  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
