+===== Dump Files =====
+  * Dump files are created for all passes where the name in the ''pass_data'' structure does not start with an astrisk (*).
+  * The dump file will, by default, contain a dump of the IR at the end of your pass.
+  * You may add additional text into the file by accessing the ''dump_file'' file descriptor like this:
+<code>
+  if (dump_file)
+    {
+      fprintf (dump_file, ... );
+    }</code>
