    I basically like that code. Maybe I'll borrow from its logic...
    although I'm NOT looking forward do think through all the maths to
    make sure it is correct in every case.<br>

              &gt; &gt; Hi Peter,<br>
              &gt; &gt;<br>
              &gt; &gt; Today Peter Stamfest wrote:<br>
              &gt; &gt;<br>
              &gt; &gt;&gt; Hi List, Hi Tobi,<br>
              &gt; &gt;&gt;<br>
              &gt; &gt;&gt; I have implemented a "rrd modify" command.
              Essentially, it takes an<br>
              &gt; &gt;&gt; input RRD, adds or removes data sources and
              creates an output RRD.<br>
              &gt; &gt;&gt;<br>
              &gt; &gt;&gt; My current imlementation can be found in
              branch "rrdmodify" at<br>
              &gt; &gt;&gt; <a moz-do-not-send="true" shape="rect"
                href="https://github.com/stamfest/rrdtool-1.x#"
                target="_blank">https://github.com/stamfest/rrdtool-1.x#</a><br>
              &gt; &gt;&gt;<br>
              &gt; &gt;&gt; That branch does not properly merge against
              master, currently. I'm<br>
              &gt; &gt;&gt; currently trying to rebase it to master...<br>
              &gt; &gt; that looks good, since it is not a bugfix, it
              would be better to<br>
              &gt; &gt; make it apply to master<br>
              &gt; So there is a realistic chance that this gets
              included? If this is the<br>
              &gt; case, I'll do the rebasing.<br>
              <br>
              sure ... especially since it just adds new functionality
              and comes<br>
              with documentation ...<br>
              <br>
              now, if you add the ability to even change the step and
              existing RRAs<br>
              while preserving the data I bet people will start
              traveling to AT<br>
              to worship you :-)<br>
