Software seldom ages gracefully. By re-factoring, you can rejuvenate your software and move to the latest hardware, operating systems, middleware, and applications. You can tap into open sources and reduce your licensing expenses, too. Re-factoring can also catapult your clients' perception of your product quality. By letting Magpie re-factor fragile portions of your product, you can add regression tests on each load, each release, and each development fix.
