+[heading Description]
+
+`sort` sorts the elements in `rng` into ascending order. `sort` is not guaranteed to be stable. Returns the sorted range.
+
+For versions of the `sort` function without a predicate, ascending order is defined by `operator<()` such that for all adjacent elements `[x,y]`, `y < x == false`.
+
+For versions of the `sort` function with a predicate, ascending order is defined by `pred` such that for all adjacent elements `[x,y]`, `pred(y, x) == false`.
+
+[heading Definition]
+
+Defined in the header file `boost/range/algorithm/sort.hpp`
+
+[heading Requirements]
+
+[*For versions of sort without a predicate:]
+
+* `RandomAccessRange` is a model of the __random_access_range__ Concept.
+* `RandomAccessRange` is mutable.
+* `RandomAccessRange`'s value type is a model of the `LessThanComparableConcept`.
+* The ordering relation on `RandomAccessRange`'s value type is a [*strict weak ordering], as defined in the `LessThanComparableConcept` requirements.
+
+[*For versions of sort with a predicate]
+
+* `RandomAccessRange` is a model of the __random_access_range__ Concept.
+* `RandomAccessRange` is mutable.
+* `BinaryPredicate` is a model of the `StrictWeakOrderingConcept`.
+* `RandomAccessRange`'s value type is convertible to both of `BinaryPredicate`'s argument types.
+
+[heading Complexity]
+
+`O(N log(N))` comparisons (both average and worst-case), where `N` is `distance(rng)`.
