+//! A set is a kind of associative container that supports unique keys (contains at
+//! most one of each key value) and provides for fast retrieval of the keys themselves.
+//! Class set supports bidirectional iterators.
+//!
+//! A set satisfies all of the requirements of a container and of a reversible container
+//! , and of an associative container. A set also provides most operations described in
+//! for unique keys.
+//!
+//! \tparam Key is the type to be inserted in the set, which is also the key_type
+//! \tparam Compare is the comparison functor used to order keys
+//! \tparam Allocator is the allocator to be used to allocate memory for this container
+//! \tparam Options is an packed option type generated using using boost::container::tree_assoc_options.
