A typical measure is to put all the templates generated into a file. You can add new ones to it as you work through the delivery process. The templates must be compiled and loaded into the application before delivery. To do this:
(CLOS::PRE-COMPILE-COMBINED-METHODS ((1 COMMON-LISP:NIL) COMMON-LISP:NIL
(COMMON-LISP:MULTIPLE-VALUE-PROG1 (CLOS::_CALL-METHOD_)
(CLOS::_CALL-METHOD_)
(CLOS::_CALL-METHOD_))))
(CLOS::DEFINE-PRE-TEMPLATES
CLOS::DEMAND-CACHING-DCODE-MISS-FUNCTION (5 COMMON-LISP:NIL (4)))
(CLOS::DEFINE-PRE-TEMPLATES
CLOS::DEMAND-CACHING-DCODE-MISS-FUNCTION (6 COMMON-LISP:NIL (4)))
No matter how many times the template form is printed, it only needs to be included in the template file once.
