+// LedRopeTCL is a C++ wrapper around the Total Control Lighting LED rope
+// device driver (TCL.h). This wrapper includes automatic setup of the LED
+// rope and allows the user to use a graphics-state like interface for
+// talking to the rope. A copy of the rope led state is held in this class
+// which makes blending operations easier. After all changes by the user
+// are applied to the rope, the hardware is updated via an explicit Draw()
+// command.
+//
+// Whole-rope blink Example:
+//  #include <SPI.h>
+//  #include <TCL.h>          // From CoolNeon (https://bitbucket.org/devries/arduino-tcl)
+//  #include "LedRopeTCL.h"
+//  LedRopeTCL led_rope(100); // 100 led-strand.
+//
+//  void setup() {}  // No setup necessary for Led rope.
+//  void loop() {
+//    led_rope.FillColor(LedRopeTCL::Color3i::Black());
+//    led_rope.Draw();
+//    delay(1000);
+//    led_rope.FillColor(LedRopeTCL::Color3i::White());
+//    led_rope.Draw();
+//    delay(1000);
