   class has been added to the library. The class is intended to be used as a
   base for any class that wants to handle parameters using the
   \texttt{ParameterHandler} class. If you derive all your classes from
   \texttt{ParameterAcceptor}, and declare your parameters either with
   \texttt{parse/declare\_parameters} methods or via the
-  \texttt{ParameterAcceptor::add\_parameter} method, then the declaring and
-  parsing of your parameter files will be automatically managed by the
-  \texttt{ParameterAcceptor::initialize} function, greatly simplifying
-  the declaration and parsing of parameters in user codes.
