  \class QScriptProgram

  \brief The QScriptProgram class encapsulates a Qt Script program.

  \ingroup script

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

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