\ccDefinition
  
%The function \ccRefName\ does this and that.

\ccInclude{CGAL/Polygon_2_algorithms.h}

\ccFunction{template <class ForwardIterator, class Traits>
ForwardIterator bottom_vertex_2(ForwardIterator first,
                                   ForwardIterator last,
                                   const Traits& traits);}
{
Returns an iterator to the bottommost point from the range
\ccStyle{[first,last)}. In case of a tie, the point
with the smallest \ccStyle{x}-coordinate is taken.
}

\ccHeading{Requirements}
\ccIndexSubitem[C]{bottom_vertex_2}{requirements}
\begin{enumerate}
    \item \ccc{Traits} is a model of the concept 
	  PolygonTraits\_2\ccIndexMainItem[c]{PolygonTraits_2}.
	  In fact, only the members \ccc{Less_yx_2} and
	  \ccc{less_yx_2_object} are used.
    \item \ccc{ForwardIterator::value_type} should be \ccc{Traits::Point_2},
\end{enumerate}
