 NAME

   less_equal  -	Binary function	object that returns true if its	first
   argument is less than or equal to	its second

 SYNOPSIS

   #include<functional>

   template <class T>
   struct less_equal : public binary_function<T,	T, bool>;

 DESCRIPTION

   less_equal is	a binary function object.  Its operator() returns true
   if x is less than or equal	to y.  You can pass a less_equal
   object	to any algorithm	that requires a	binary
   function.  For example,  the sort	algorithm can accept a binary
   function as an alternate  comparison object to	sort a
   sequence.  less_equal	would be used in  that algorithm	in the
   following manner:

   vector<int> vec1;
   sort(vec1.begin(), vec1.end(),less_equal<int>());

   After	this call to sort, vec1	will be	sorted in ascending order.

 INTERFACE

   template <class T>
   struct less_equal : binary_function<T, T, bool> {
   typedef typename binary_function<T, T, bool>::second_argument_type
 						second_argument_type;
    typedef typename binary_function<T, T, bool>::first_argument_type
 						 first_argument_type;
    typedef typename binary_function<T, T, bool>::result_type
 						 result_type;
    bool	operator() (const T&, const T&)	const;
   };

 WARNING

   If your compiler does	not support default template parameters, then
   you need to always supply	the Allocator template argument.  For
   instance, you'll have to write :

   vector<int, allocator<int> >

   instead of

   vector<int>
