+    <p>Real-time logic simulator, designed to help in learning of basic
+    boolean logic and electronics.</p>
+    <p>It uses OpenGL hardware-accelerated rendering and a custom UI
+    designed for a fast workflow and a very low learning curve, letting the
+    students concentrate on learning the subject instead of spending time
+    learning the tool.</p>
