SPARC Solaris only. Used to re-target the licensing requirements of the delivery image to those of the delivered application. :product-code is a fixnum supplied by Lisp Support. If the :product-code is :none, the application will have no keyfile protection. You should not use the product code :none without a prior arrangement with Lisp Support. If :product-code is not supplied then the image is not re-targeted and will require a "LispWorks Delivery" key to restart. Note that this should not be a problem while developing an application.
