-/// Automatically resizable buffer class based on std::streambuf.
-/**
- * The @c basic_streambuf class is derived from @c std::streambuf to associate
- * the streambuf's input and output sequences with one or more character
- * arrays. These character arrays are internal to the @c basic_streambuf
- * object, but direct access to the array elements is provided to permit them
- * to be used efficiently with I/O operations. Characters written to the output
- * sequence of a @c basic_streambuf object are appended to the input sequence
- * of the same object.
- *
- * The @c basic_streambuf class's public interface is intended to permit the
- * following implementation strategies:
- *
- * @li A single contiguous character array, which is reallocated as necessary
- * to accommodate changes in the size of the character sequence. This is the
- * implementation approach currently used in Asio.
- *
- * @li A sequence of one or more character arrays, where each array is of the
- * same size. Additional character array objects are appended to the sequence
- * to accommodate changes in the size of the character sequence.
- *
- * @li A sequence of one or more character arrays of varying sizes. Additional
- * character array objects are appended to the sequence to accommodate changes
- * in the size of the character sequence.
- *
- * The constructor for basic_streambuf accepts a @c size_t argument specifying
- * the maximum of the sum of the sizes of the input sequence and output
- * sequence. During the lifetime of the @c basic_streambuf object, the following
- * invariant holds:
- * @code size() <= max_size()@endcode
- * Any member function that would, if successful, cause the invariant to be
- * violated shall throw an exception of class @c std::length_error.
- *
- * The constructor for @c basic_streambuf takes an Allocator argument. A copy
- * of this argument is used for any memory allocation performed, by the
- * constructor and by all member functions, during the lifetime of each @c
- * basic_streambuf object.
- *
- * @par Examples
- * Writing directly from an streambuf to a socket:
- * @code
- * asio::streambuf b;
- * std::ostream os(&b);
- * os << "Hello, World!\n";
- *
- * // try sending some data in input sequence
- * size_t n = sock.send(b.data());
- *
- * b.consume(n); // sent data is removed from input sequence
- * @endcode
- *
- * Reading from a socket directly into a streambuf:
- * @code
- * asio::streambuf b;
- *
- * // reserve 512 bytes in output sequence
- * asio::streambuf::mutable_buffers_type bufs = b.prepare(512);
- *
- * size_t n = sock.receive(bufs);
- *
- * // received data is "committed" from output sequence to input sequence
- * b.commit(n);
- *
- * std::istream is(&b);
- * std::string s;
- * is >> s;
- * @endcode

-/// Provides waitable timer functionality.
-/**
- * The basic_waitable_timer class template provides the ability to perform a
- * blocking or asynchronous wait for a timer to expire.
- *
- * A waitable timer is always in one of two states: "expired" or "not expired".
- * If the wait() or async_wait() function is called on an expired timer, the
- * wait operation will complete immediately.
- *
- * Most applications will use one of the asio::steady_timer,
- * asio::system_timer or asio::high_resolution_timer typedefs.
- *
- * @note This waitable timer functionality is for use with the C++11 standard
- * library's @c &lt;chrono&gt; facility, or with the Boost.Chrono library.
- *
- * @par Thread Safety
- * @e Distinct @e objects: Safe.@n
- * @e Shared @e objects: Unsafe.
- *
- * @par Examples
- * Performing a blocking wait (C++11):
- * @code
- * // Construct a timer without setting an expiry time.
- * asio::steady_timer timer(io_service);
- *
- * // Set an expiry time relative to now.
- * timer.expires_from_now(std::chrono::seconds(5));
- *
- * // Wait for the timer to expire.
- * timer.wait();
- * @endcode
- *
- * @par 
- * Performing an asynchronous wait (C++11):
- * @code
- * void handler(const asio::error_code& error)
- * {
- *   if (!error)
- *   {
- *     // Timer expired.
- *   }
- * }
- *
- * ...
- *
- * // Construct a timer with an absolute expiry time.
- * asio::steady_timer timer(io_service,
- *     std::chrono::steady_clock::now() + std::chrono::seconds(60));
- *
- * // Start an asynchronous wait.
- * timer.async_wait(handler);
- * @endcode
- *
- * @par Changing an active waitable timer's expiry time
- *
- * Changing the expiry time of a timer while there are pending asynchronous
- * waits causes those wait operations to be cancelled. To ensure that the action
- * associated with the timer is performed only once, use something like this:
- * used:
- *
- * @code
- * void on_some_event()
- * {
- *   if (my_timer.expires_from_now(seconds(5)) > 0)
- *   {
- *     // We managed to cancel the timer. Start new asynchronous wait.
- *     my_timer.async_wait(on_timeout);
- *   }
- *   else
- *   {
- *     // Too late, timer has already expired!
- *   }
- * }
- *
- * void on_timeout(const asio::error_code& e)
- * {
- *   if (e != asio::error::operation_aborted)
- *   {
- *     // Timer was not cancelled, take necessary action.
- *   }
- * }
- * @endcode
- *
- * @li The asio::basic_waitable_timer::expires_from_now() function
- * cancels any pending asynchronous waits, and returns the number of
- * asynchronous waits that were cancelled. If it returns 0 then you were too
- * late and the wait handler has already been executed, or will soon be
- * executed. If it returns 1 then the wait handler was successfully cancelled.
- *
- * @li If a wait handler is cancelled, the asio::error_code passed to
- * it contains the value asio::error::operation_aborted.
