  18 [heading Description]
  19
  20 `reverse` reverses a range. Returns a reference to the reversed range.
  21
  22 [heading Definition]
  23
  24 Defined in the header file `boost/range/algorithm/reverse.hpp`
  25
  26 [heading Requirements]
  27
  28 * `BidirectionalRange` is a model of the __bidirectional_range__ Concept.
  29 * `BidirectionalRange` is mutable.
  30
  31 [heading Complexity]
  32
  33 Linear. `reverse` makes `distance(rng)/2` calls to `iter_swap`.
