+    <title>Introduction</title>
+      <p>
+	The egd module is an interface for 2d-image rendering and is used by
+	Percept to generate dynamic graphs to its web pages. All code is pure
+	erlang, no drivers needed.
+      </p>
+      <p>
+	The library is intended for small to medium image sizes with low
+	complexity for optimal performance. The library handles horizontal
+	lines better then vertical lines.
+      </p>
+      <p>
+	The foremost purpose for this module is to enable users to 
+	generate images from erlang code and/or datasets and to 
+	send these images to either files or web servers.
+      </p>
