## Detailed Description

The QScriptProgram class encapsulates a Qt Script program.

QScriptProgram retains the compiled representation of the script if possible. Thus, QScriptProgram can be used to evaluate the same script multiple times more efficiently.

     QScriptEngine engine;
     QScriptProgram program("1 + 2");
     QScriptValue result = engine.evaluate(program);
