+/// Provides waitable timer functionality.
+/**
+ * The basic_deadline_timer class template provides the ability to perform a
+ * blocking or asynchronous wait for a timer to expire.
+ *
+ * A deadline 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 the boost::asio::deadline_timer typedef.
+ *
+ * @par Thread Safety
+ * @e Distinct @e objects: Safe.@n
+ * @e Shared @e objects: Unsafe.
+ *
+ * @par Examples
+ * Performing a blocking wait:
+ * @code
+ * // Construct a timer without setting an expiry time.
+ * boost::asio::deadline_timer timer(io_service);
+ *
+ * // Set an expiry time relative to now.
+ * timer.expires_from_now(boost::posix_time::seconds(5));
+ *
+ * // Wait for the timer to expire.
+ * timer.wait();
+ * @endcode
+ *
+ * @par 
+ * Performing an asynchronous wait:
+ * @code
+ * void handler(const boost::system::error_code& error)
+ * {
+ *   if (!error)
+ *   {
+ *     // Timer expired.
+ *   }
+ * }
+ *
+ * ...
+ *
+ * // Construct a timer with an absolute expiry time.
+ * boost::asio::deadline_timer timer(io_service,
+ *     boost::posix_time::time_from_string("2005-12-07 23:59:59.000"));
+ *
+ * // Start an asynchronous wait.
+ * timer.async_wait(handler);
+ * @endcode
+ *
+ * @par Changing an active deadline_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 boost::system::error_code& e)
+ * {
+ *   if (e != boost::asio::error::operation_aborted)
+ *   {
+ *     // Timer was not cancelled, take necessary action.
+ *   }
+ * }
+ * @endcode
+ *
+ * @li The boost::asio::basic_deadline_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 boost::system::error_code passed to
+ * it contains the value boost::asio::error::operation_aborted.

+/// Provides signal functionality.
+/**
+ * The basic_signal_set class template provides the ability to perform an
+ * asynchronous wait for one or more signals to occur.
+ *
+ * Most applications will use the boost::asio::signal_set typedef.
+ *
+ * @par Thread Safety
+ * @e Distinct @e objects: Safe.@n
+ * @e Shared @e objects: Unsafe.
+ *
+ * @par Example
+ * Performing an asynchronous wait:
+ * @code
+ * void handler(
+ *     const boost::system::error_code& error,
+ *     int signal_number)
+ * {
+ *   if (!error)
+ *   {
+ *     // A signal occurred.
+ *   }
+ * }
+ *
+ * ...
+ *
+ * // Construct a signal set registered for process termination.
+ * boost::asio::signal_set signals(io_service, SIGINT, SIGTERM);
+ *
+ * // Start an asynchronous wait for one of the signals to occur.
+ * signals.async_wait(handler);
+ * @endcode
+ *
+ * @par Queueing of signal notifications
+ *
+ * If a signal is registered with a signal_set, and the signal occurs when
+ * there are no waiting handlers, then the signal notification is queued. The
+ * next async_wait operation on that signal_set will dequeue the notification.
+ * If multiple notifications are queued, subsequent async_wait operations
+ * dequeue them one at a time. Signal notifications are dequeued in order of
+ * ascending signal number.
+ *
+ * If a signal number is removed from a signal_set (using the @c remove or @c
+ * erase member functions) then any queued notifications for that signal are
+ * discarded.
+ *
+ * @par Multiple registration of signals
+ *
+ * The same signal number may be registered with different signal_set objects.
+ * When the signal occurs, one handler is called for each signal_set object.
+ *
+ * Note that multiple registration only works for signals that are registered
+ * using Asio. The application must not also register a signal handler using
+ * functions such as @c signal() or @c sigaction().
+ *
+ * @par Signal masking on POSIX platforms
+ *
+ * POSIX allows signals to be blocked using functions such as @c sigprocmask()
+ * and @c pthread_sigmask(). For signals to be delivered, programs must ensure
+ * that any signals registered using signal_set objects are unblocked in at
+ * least one thread.

+/// 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
+ * boost::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
+ * boost::asio::streambuf b;
+ *
+ * // reserve 512 bytes in output sequence
+ * boost::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
