//! The class template treap is an intrusive treap container that
//! is used to construct intrusive set and multiset containers. The no-throw
//! guarantee holds only, if the value_compare object and priority_compare object
//! don't throw.
//!
//! The template parameter \c T is the type to be managed by the container.
//! The user can specify additional options and if no options are provided
//! default options are used.
//!
//! The container supports the following options:
//! \c base_hook<>/member_hook<>/value_traits<>,
//! \c constant_time_size<>, \c size_type<>,
//! \c compare<> and \c priority_compare<>

   //!   to check if the insertion will be successful.
   //!
   //!   If the check is successful, the user can construct the value_type and use
