+/**
+ Creates a new Fl_Pack widget using the given position, size,
+ and label string. The default boxtype is FL_NO_BOX.
+ <P>The destructor <I>also deletes all the children</I>. This allows a
+ whole tree to be deleted at once, without having to keep a pointer to
+ all the children in the user code. A kludge has been done so the
+ Fl_Pack and all of it's children can be automatic (local)
+ variables, but you must declare the Fl_Pack<I>first</I>, so
+ that it is destroyed last.
