+description KerfScript is a declarative, parametric programming language for designing parts for laser cutters. It is to laser cutters what OpenSCAD is to 3D printers, except it was designed for flat parts from the start: programs build 2D geometry, assign it to cut, score or engrave layers, and group shapes into parts, and the renderer applies kerf compensation, packs parts on sheets and exports SVG or DXF.

+  // A coaster with a hole, an engraved ring and a scored border.
+  size = 90; // [60:5:120]
+
+  difference() {
+    circle(d = size);
+    circle(d = 6);
+  }
+  engrave() difference() { circle(d = size - 16); circle(d = size - 22); }

+  $thickness = 3;
+  $kerf = 0.15;
