Well said kcott. The ideal of the DRY principle is that every piece of knowledge should have a single, unambiguous, authoritative representation within a system. Note that DRY is broader than just code, including things like database schemas, configuration files, test plans, build systems and doco. Violations of DRY are sometimes called WET: "write everything twice" or "we enjoy typing". ;-)

Bod, in your current system are there any places where you find yourself having to make multiple changes in response to a single value changing? If so, you might enjoy thinking about how to eliminate these sort of error-prone chores. In large complex legacy environments, with multiple programming languages and tools in use across multiple platforms, Perl is an ideal glue language for building little tools to eliminate DRY violations.
