-You can see a description
-(the one which was provided by the author of the box),
-the author(s) of the box (usually e-mail adress(es)) and
-the categories to which the box belongs.
-Finally comes the lists of inputs and outputs of the box.
-For each input or output, \bbi provides
-its \emph{name} ,
-its \emph{type} (between \texttt{<} and \texttt{>}, e.g. \texttt{<Int>})
-and a description.
-Remark that the box \texttt{Add} is not a 'complex' black box
-but an 'atomic' box, hence its help does not
-include a pipeline graph.
-
-You can see that \texttt{Add} boxes have two inputs,
-with name \texttt{In1} and \texttt{In2},
-and an output, with name \texttt{Out}.
-
-You can set the input \texttt{In1}
-of the \texttt{Add} box \texttt{a} to the value $1$
-by the command :
