 <Class name='TimingData'>
+	<Description>
+		GetBPMsAndTimes, GetStops, GetDelays, GetLabels, GetWarps, GetCombos, GetTimeSignatures, GetTickcounts, GetFakes, GetScrolls, and GetSpeeds all have two different modes.<br />
+		If the metric TimingData:GetReturnsNumbers is false (the default), they return tables of strings.  The strings are numbers separated by '='.<br />
+		If the metric TimingData:GetReturnsNumbers is true, they return tables of tables, and the inner tables contain numbers as described for each function.<br />
+		The first form is kept around and is the default for compatibility with older themes.  The advantage of the second form is that you no longer need to have a bit of code in your theme to transform the string into a table of numbers before you can use it.<br />
+		Example:<br />
+		local bpmsand= timing_data:GetBPMsAndTimes()<br />
+		for i, s in ipairs(bpmsand) do<br />
+		local sand= split("=", s)<br />
+		bpmsand[i]= {tonumber(sand[1]), tonumber(sand[2])}<br />
+		end<br />
+		-- do something that looks at all the bpms and times. <br />
+		Becomes:<br />
+		local bpmsand= timing_data:GetBPMsAndTimes()<br />
+		-- do something that looks at all the bpms and times. <br />
