<p>The authors have created an object-oriented scripting interface to a mature density functional theory code. The interface gives users a high-level and flexible handle on the code without rewriting the underlying number-crunching code. They discuss design issues with respect to object reuse and extendibility as well as the advantages of homogeneous interfaces to multiple codes. The concrete implementation is illustrated in a class diagram and the use of the interface is demonstrated by calculations for a gold nanowire.</p>
