+description      = "Chapter 3 - Cylon LED Bar: flowing light upgraded to a menacing scanner"
+long-description = """Building a smooth flowing LED bar on the Raspberry Pi
+Pico with Ada - from a simple chasing light to a proper menacing Cylon scanner
+effect using real-time delays.
+
+In this chapter we turn ten LEDs into a flowing light bar. We start with the
+basic Freenove example using an array of RP.GPIO.GPIO_Point (aliased limited
+tagged types). We then improve it with a pre-calculated sine-harmonic timing
+table to create a realistic Cylon scanner - all done with Ada.Real_Time and
+zero floating-point at runtime for perfect jitter-free movement.
+
+The two programs included are:
+
+1. Sketch_03_1_Flowing_Light  - straight port of the classic flowing light
+2. Cylon_Light                - the final dramatic Cylon scanner with organic easing
+3. Cylon_Light_Float          - Floating point version of Cylon_Light

+then completely messed it up.)
