+/**
+ * <p>
+ * Nashorn parser API provides interfaces to represent ECMAScript source code
+ * as abstract syntax trees (AST) and Parser to parse ECMAScript source scripts.
+ * </p>
+ * <p>
+ * Using parser API user can write Java code to access parse tree
+ * representation of ECMAScript source. Script source may be a file,
+ * a URL or a String. Unless stated otherwise null argument in methods of this
+ * package result in NullPointerException being thrown.
+ * </p>
+ *
+ * <pre>
+ * <code>
+ * import jdk.nashorn.api.tree.*;
+ * import java.io.File;
+ *
+ * // Simple example that prints warning on 'with' statements
+ * public class Main {
+ *     public static void main(String[] args) throws Exception {
+ *         // Create a new parser instance
+ *         Parser parser = Parser.create();
+ *         File sourceFile = new File(args[0]);
+ *
+ *         // Parse given source File using parse method.
+ *         // Pass a diagnostic listener to print error messages.
+ *         CompilationUnitTree cut = parser.parse(sourceFile,
+ *             (d) -&gt; { System.out.println(d); });
+ *
+ *         if (cut != null) {
+ *             // call Tree.accept method passing a SimpleTreeVisitor
+ *             cut.accept(new SimpleTreeVisitor&lt;Void, Void&gt;() {
+ *                 // visit method for 'with' statement
