+"""A Telemetry page_action that performs the "drag" action on pages.
+
+Action parameters are:
+- selector: If no selector is defined then the action attempts to drag the
+            document element on the page.
+- element_function: CSS selector used to evaluate callback when test completes
+- text: The element with exact text is selected.
+- left_start_ratio: ratio of start point's left coordinate to the element
+                    width.
+- top_start_ratio: ratio of start point's top coordinate to the element height.
+- left_end_ratio: ratio of end point's left coordinate to the element width.
+- left_end_ratio: ratio of end point's top coordinate to the element height.
+- speed_in_pixels_per_second: speed of the drag gesture in pixels per second.
+- use_touch: boolean value to specify if gesture should use touch input or not.
