A method for creating a reusable library, including providing one or more functions, providing a function table for the provided one or more functions, and providing a configuration structure for communicating values between the provided one or more functions and a program that calls the reusable library. The program that calls the reusable library communicates a function table structure to the reusable library containing information as to which of the one or more functions are desirable. When those of the one or more functions that are not desirable contain dependencies, those dependencies are canceled.
