+When writing scripts you may find that you need to access private java methods.
+This script shows how you can do this easily.
+
+WARNING: we do not consider private methods to be part of the public API, so they may
+be changed or removed at any time.
+If you think you have a strong case for making a method public then either:
+
+1. Ask on the ZAP Dev Group: https://groups.google.com/group/zaproxy-develop
+2. Submit a pull request making the change (but be prepared for it to be rejected)
