+The `edge_list` class is an adaptor that turns a pair of edge iterators into a
+graph type that models the [EdgeListGraph] concept. The `value_type` of the edge
+iterator must be a `pair` (or at least have `first` and `second` members). The
+`first_type` and `second_type` of the pair must be the same and they will be
+used for the graph's `vertex_descriptor`. The `ValueType` and `DifferenceType`
+template parameters are only needed if your compiler does not support partial
+specialization. Otherwise they default to the correct types.
