+ * Revision 1.9  2005/02/13 16:13:33  oetiker
+ * let rrd_graph return the actual value range it picked ...
+ * -- Henrik Stoerner <henrik@hswn.dk>
+ *
+ * Revision 1.8  2004/05/26 22:11:12  oetiker
+ * reduce compiler warnings. Many small fixes. -- Mike Slifcak <slif@bellsouth.net>
+ *
+ * Revision 1.7  2003/11/12 22:14:26  oetiker
+ * allow to pass an open filehandle into rrd_graph as an extra argument
+ *
+ * Revision 1.6  2003/11/11 19:46:21  oetiker
+ * replaced time_value with rrd_time_value as MacOS X introduced a struct of that name in their standard headers
+ *
+ * Revision 1.5  2003/04/25 18:35:08  jake
+ * Alternate update interface, updatev. Returns info about CDPs written to disk as result of update. Output format is similar to rrd_info, a hash of key-values.
