		@@ -5,11 +5,19 @@ Standard SQL makes (moving) window queries over timeseries fairly akward. Since
		these kind of time based rollups are very common when working with timeseries data,
		FnordMetric introduces a new GROUP OVER TIMEWINDOW clause.

		---

		The syntax for the GROUP OVER TIMEWINDOW clause is:

		GROUP OVER TIMEWINDOW(time_column, window_expr [, step_expr]) [BY ...]

		Where `time\_col` is the column that contains the time for each row, `window\_expr`
		is an expression that returns the length of the window in seconds and `step\_expr`
		is an expression that returns the output timestep in seconds.

		Here is a simple example that should demonstrate the general concept before we
		dig into the detailed semantics of the GROUP OVER TIMEWINDOW clause:

		---

		_Display the moving average of mymetric's value over a moving 60s window_

		SELECT time, mean(value) FROM mymetric GROUP OVER TIMEWINDOW(time, 60);
