+ * 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.
+ *
+ * Revision 1.4 2003/04/01 22:52:23 jake
+ * Fix Win32 build. VC++ 6.0 and 7.0 now use the thread-safe code.
