+If this value is set, we override the default algorithm for choosing which
+circuit's cells to deliver or relay first.  When the value is 0, we
+round-robin between the active circuits on a connection, delivering one cell
+from each in turn.  When the value is positive, we prefer delivering cells
+from whichever connection has the lowest weighted cell count, where cells are
+weighted exponentially according to the supplied CircuitPrioirityHalflife
+value (in seconds).  If this option is not set at all, we use the behavior
+recommended in the current consensus networkstatus.
+This is an advanced option; you generally shouldn't have mess with it.
