+
+[heading Description]
+
+`replace_copy` copy every element `x` in `rng` such that the corresponding element in the output range `y` is `x == what ? with_what : x`.
+
+[heading Definition]
+
+Defined in the header file `boost/range/algorithm/replace_copy.hpp`
+
+[heading Requirements]
+
+* `ForwardRange` is a model of the __forward_range__ Concept.
+* `ForwardRange` is mutable.
+* `Value` is convertible to `ForwardRange`'s value type.
+* `Value` is a model of the `AssignableConcept`.
+* `OutputIterator` is a model of the `OutputIteratorConcept`.
+
+[heading Complexity]
+
+Linear. `replace_copy` performs exactly `distance(rng)`.
