+ *
+ * @version v0.4, 2011/02/05 (February) -- Patch of Keheliya Gallaba is added. Now you

+ *
+ * @version v0.4, 2011/02/05 (February) -- Patch of Keheliya Gallaba is added. Now you

+/**
+ * <dl>
+ * <dt>Purpose: GraphViz Java API
+ * <dd>
+ * <dt>Description:
+ * <dd>With this Java class you can simply call dot from your Java programs
+ * <dt>Example usage:
+ * <dd>
+ *
+ * <pre>
+ * GraphViz gv = new GraphViz();
+ * gv.addln(gv.start_graph());
+ * gv.addln("A -> B;");
+ * gv.addln("A -> C;");
+ * gv.addln(gv.end_graph());
+ * System.out.println(gv.getDotSource());
+ *
+ * String type = "gif";
+ * File out = new File("out." + type); // out.gif in this example
+ * gv.writeGraphToFile(gv.getGraph(gv.getDotSource(), type), out);
+ * </pre>
+ *
+ * </dd>
+ * </dl>
+ *
+ * @version v0.4, 2011/02/05 (February) -- Patch of Keheliya Gallaba is added. Now you
+ * can specify the type of the output file: gif, dot, fig, pdf, ps, svg, png, etc.
+ * @version v0.3, 2010/11/29 (November) -- Windows support + ability
+ * to read the graph from a text file
+ * @version v0.2, 2010/07/22 (July) -- bug fix
+ * @version v0.1, 2003/12/04 (December) -- first release
+ * @author Laszlo Szathmary (<a href="jabba.laci@gmail.com">jabba.laci@gmail.com</a>)
