-Locale Independent Numeric Input
---------------------------------
-* Regardles of locale you are in, rrdtool always expects input to be numbers
- (LC_NUMERIC) in C or POSIX locale for numbers. (not 1,1 but 1.1) this is
- necessary to make things like RPN work as it uses , as a separator.
+RRDtool dump / restore incompatibility
+--------------------------------------
+* rrdtool dump 1.3 does emit completely legal XML. Basically this
+ means that it contains an XML header and a DOCTYPE definition.
+ Unfortunately this causes older versions of rrdtool restore to be
+ unhappy.
+
+* To restore a new dump with an old rrdtool restore version, either
+ remove the XML header and the doctype by hand (both on the first
+ line of the dump) or use rrdtool dump --no-header.
