+ * @ingroup functors
+ *
+ * Binders turn functions/functors with two arguments into functors with
+ * a single argument, storing an argument to be applied later. For
+ * example, a variable @c B of type @c binder1st is constructed from a
+ * functor @c f and an argument @c x. Later, B's @c operator() is called
+ * with a single argument @c y. The return value is the value of @c f(x,y).
+ * @c B can be "called" with various arguments (y1, y2, ...) and will in
+ * turn call @c f(x,y1), @c f(x,y2), ...
+ *
+ * The function @c bind1st is provided to save some typing. It takes the
+ * function and an argument as parameters, and returns an instance of
+ * @c binder1st.
+ *
+ * The type @c binder2nd and its creator function @c bind2nd do the same
+ * thing, but the stored argument is passed as the second parameter instead
+ * of the first, e.g., @c bind2nd(std::minus<float>,1.3) will create a
+ * functor whose @c operator() accepts a floating-point number, subtracts
+ * 1.3 from it, and returns the result. (If @c bind1st had been used,
+ * the functor would perform "1.3 - x" instead.
+ *
+ * Creator-wrapper functions like @c bind1st are intended to be used in
+ * calling algorithms. Their return values will be temporary objects.
+ * (The goal is to not require you to type names like
+ * @c std::binder1st<std::plus<int>> for declaring a variable to hold the
+ * return value from @c bind1st(std::plus<int>,5).
+ *
+ * These become more useful when combined with the composition functions.
