+    ast
+    ~~~
+
+    The `ast` module helps Python applications to process trees of the Python
+    abstract syntax grammar.  The abstract syntax itself might change with
+    each Python release; this module helps to find out programmatically what
+    the current grammar looks like and allows modifications of it.
+
+    An abstract syntax tree can be generated by passing `ast.PyCF_ONLY_AST` as
+    a flag to the `compile()` builtin function or by using the `parse()`
+    function from this module.  The result will be a tree of objects whose
+    classes all inherit from `ast.AST`.
+
+    A modified abstract syntax tree can be compiled into a Python code object
+    using the built-in `compile()` function.
+
+    Additionally various helper functions are provided that make working with
+    the trees simpler.  The main intention of the helper functions and this
+    module in general is to provide an easy to use interface for libraries
+    that work tightly with the python syntax (template engines for example).

+class Template(object):
+
+    r"""Represents a compiled template.
+
+    :class:`.Template` includes a reference to the original
+    template source (via the :attr:`.source` attribute)
+    as well as the source code of the
+    generated Python module (i.e. the :attr:`.code` attribute),
+    as well as a reference to an actual Python module.
+
+    :class:`.Template` is constructed using either a literal string
+    representing the template text, or a filename representing a filesystem
+    path to a source file.
+
+    :param text: textual template source.  This argument is mutually
+     exclusive versus the ``filename`` parameter.
+
+    :param filename: filename of the source template.  This argument is
+     mutually exclusive versus the ``text`` parameter.
+
+    :param buffer_filters: string list of filters to be applied
+     to the output of ``%def``\ s which are buffered, cached, or otherwise
+     filtered, after all filters
+     defined with the ``%def`` itself have been applied. Allows the
+     creation of default expression filters that let the output
+     of return-valued ``%def``\ s "opt out" of that filtering via
+     passing special attributes or objects.
+
+    :param bytestring_passthrough: When ``True``, and ``output_encoding`` is
+     set to ``None``, and :meth:`.Template.render` is used to render,
+     the `StringIO` or `cStringIO` buffer will be used instead of the
+     default "fast" buffer.   This allows raw bytestrings in the
+     output stream, such as in expressions, to pass straight
+     through to the buffer.  This flag is forced
+     to ``True`` if ``disable_unicode`` is also configured.
+
+     .. versionadded:: 0.4
+        Added to provide the same behavior as that of the previous series.
+
+    :param cache_args: Dictionary of cache configuration arguments that
+     will be passed to the :class:`.CacheImpl`.   See :ref:`caching_toplevel`.
+
+    :param cache_dir:
+
+     .. deprecated:: 0.6
+        Use the ``'dir'`` argument in the ``cache_args`` dictionary.
+        See :ref:`caching_toplevel`.
+
+    :param cache_enabled: Boolean flag which enables caching of this
+     template.  See :ref:`caching_toplevel`.
+
+    :param cache_impl: String name of a :class:`.CacheImpl` caching
+     implementation to use.   Defaults to ``'beaker'``.
+
+    :param cache_type:
+
+     .. deprecated:: 0.6
+        Use the ``'type'`` argument in the ``cache_args`` dictionary.
+        See :ref:`caching_toplevel`.
+
+    :param cache_url:
+
+     .. deprecated:: 0.6
+        Use the ``'url'`` argument in the ``cache_args`` dictionary.
+        See :ref:`caching_toplevel`.
+
+    :param default_filters: List of string filter names that will
+     be applied to all expressions.  See :ref:`filtering_default_filters`.
+
+    :param disable_unicode: Disables all awareness of Python Unicode
+     objects.  See :ref:`unicode_disabled`.
+
+    :param enable_loop: When ``True``, enable the ``loop`` context variable.
+     This can be set to ``False`` to support templates that may
+     be making usage of the name "``loop``".   Individual templates can
+     re-enable the "loop" context by placing the directive
+     ``enable_loop="True"`` inside the ``<%page>`` tag -- see
+     :ref:`migrating_loop`.
+
+    :param encoding_errors: Error parameter passed to ``encode()`` when
+     string encoding is performed. See :ref:`usage_unicode`.
+
+    :param error_handler: Python callable which is called whenever
+     compile or runtime exceptions occur. The callable is passed
+     the current context as well as the exception. If the
+     callable returns ``True``, the exception is considered to
+     be handled, else it is re-raised after the function
+     completes. Is used to provide custom error-rendering
+     functions.
+
+     .. seealso::
+
+        :paramref:`.Template.include_error_handler` - include-specific
+        error handler function
+
+    :param format_exceptions: if ``True``, exceptions which occur during
+     the render phase of this template will be caught and
+     formatted into an HTML error page, which then becomes the
+     rendered result of the :meth:`.render` call. Otherwise,
+     runtime exceptions are propagated outwards.
+
+    :param imports: String list of Python statements, typically individual
+     "import" lines, which will be placed into the module level
+     preamble of all generated Python modules. See the example
+     in :ref:`filtering_default_filters`.
+
+    :param future_imports: String list of names to import from `__future__`.
+     These will be concatenated into a comma-separated string and inserted
+     into the beginning of the template, e.g. ``futures_imports=['FOO',
+     'BAR']`` results in ``from __future__ import FOO, BAR``.  If you're
+     interested in using features like the new division operator, you must
+     use future_imports to convey that to the renderer, as otherwise the
+     import will not appear as the first executed statement in the generated
+     code and will therefore not have the desired effect.
+
+    :param include_error_handler: An error handler that runs when this template
+     is included within another one via the ``<%include>`` tag, and raises an
+     error.  Compare to the :paramref:`.Template.error_handler` option.
+
+     .. versionadded:: 1.0.6
+
+     .. seealso::
+
+        :paramref:`.Template.error_handler` - top-level error handler function
+
+    :param input_encoding: Encoding of the template's source code.  Can
+     be used in lieu of the coding comment. See
+     :ref:`usage_unicode` as well as :ref:`unicode_toplevel` for
+     details on source encoding.
+
+    :param lookup: a :class:`.TemplateLookup` instance that will be used
+     for all file lookups via the ``<%namespace>``,
+     ``<%include>``, and ``<%inherit>`` tags. See
+     :ref:`usage_templatelookup`.
+
+    :param module_directory: Filesystem location where generated
+     Python module files will be placed.
+
+    :param module_filename: Overrides the filename of the generated
+     Python module file. For advanced usage only.
+
+    :param module_writer: A callable which overrides how the Python
+     module is written entirely.  The callable is passed the
+     encoded source content of the module and the destination
+     path to be written to.   The default behavior of module writing
+     uses a tempfile in conjunction with a file move in order
+     to make the operation atomic.   So a user-defined module
+     writing function that mimics the default behavior would be:
+
+     .. sourcecode:: python
+
+         import tempfile
+         import os
+         import shutil
+
+         def module_writer(source, outputpath):
+             (dest, name) = \\
+                 tempfile.mkstemp(
+                     dir=os.path.dirname(outputpath)
+                 )
+
+             os.write(dest, source)
+             os.close(dest)
+             shutil.move(name, outputpath)
+
+         from mako.template import Template
+         mytemplate = Template(
+                         filename="index.html",
+                         module_directory="/path/to/modules",
+                         module_writer=module_writer
+                     )
+
+     The function is provided for unusual configurations where
+     certain platform-specific permissions or other special
+     steps are needed.
+
+    :param output_encoding: The encoding to use when :meth:`.render`
+     is called.
+     See :ref:`usage_unicode` as well as :ref:`unicode_toplevel`.
+
+    :param preprocessor: Python callable which will be passed
+     the full template source before it is parsed. The return
+     result of the callable will be used as the template source
+     code.
+
+    :param lexer_cls: A :class:`.Lexer` class used to parse
+     the template.   The :class:`.Lexer` class is used by
+     default.
+
+     .. versionadded:: 0.7.4
+
+    :param strict_undefined: Replaces the automatic usage of
+     ``UNDEFINED`` for any undeclared variables not located in
+     the :class:`.Context` with an immediate raise of
+     ``NameError``. The advantage is immediate reporting of
+     missing variables which include the name.
+
+     .. versionadded:: 0.3.6
+
+    :param uri: string URI or other identifier for this template.
+     If not provided, the ``uri`` is generated from the filesystem
+     path, or from the in-memory identity of a non-file-based
+     template. The primary usage of the ``uri`` is to provide a key
+     within :class:`.TemplateLookup`, as well as to generate the
+     file path of the generated Python module file, if
+     ``module_directory`` is specified.

+    Representation of a socket with a mysql server.
+
+    The proper way to get an instance of this class is to call
+    connect().
+
+    Establish a connection to the MySQL database. Accepts several
+    arguments:
+
+    :param host: Host where the database server is located
+    :param user: Username to log in as
+    :param password: Password to use.
+    :param database: Database to use, None to not use a particular one.
+    :param port: MySQL port to use, default is usually OK. (default: 3306)
+    :param bind_address: When the client has multiple network interfaces, specify
+        the interface from which to connect to the host. Argument can be
+        a hostname or an IP address.
+    :param unix_socket: Optionally, you can use a unix socket rather than TCP/IP.
+    :param read_timeout: The timeout for reading from the connection in seconds (default: None - no timeout)
+    :param write_timeout: The timeout for writing to the connection in seconds (default: None - no timeout)
+    :param charset: Charset you want to use.
+    :param sql_mode: Default SQL_MODE to use.
+    :param read_default_file:
+        Specifies  my.cnf file to read these parameters from under the [client] section.
+    :param conv:
+        Conversion dictionary to use instead of the default one.
+        This is used to provide custom marshalling and unmarshaling of types.
+        See converters.
+    :param use_unicode:
+        Whether or not to default to unicode strings.
+        This option defaults to true for Py3k.
+    :param client_flag: Custom flags to send to MySQL. Find potential values in constants.CLIENT.
+    :param cursorclass: Custom cursor class to use.
+    :param init_command: Initial SQL statement to run when connection is established.
+    :param connect_timeout: Timeout before throwing an exception when connecting.
+        (default: 10, min: 1, max: 31536000)
+    :param ssl:
+        A dict of arguments similar to mysql_ssl_set()'s parameters.
+        For now the capath and cipher arguments are not supported.
+    :param read_default_group: Group to read from in the configuration file.
+    :param compress: Not supported
+    :param named_pipe: Not supported
+    :param autocommit: Autocommit mode. None means use server default. (default: False)
+    :param local_infile: Boolean to enable the use of LOAD DATA LOCAL command. (default: False)
+    :param max_allowed_packet: Max size of packet sent to server in bytes. (default: 16MB)
+        Only used to limit size of "LOAD LOCAL INFILE" data packet smaller than default (16KB).
+    :param defer_connect: Don't explicitly connect on contruction - wait for connect call.
+        (default: False)
+    :param auth_plugin_map: A dict of plugin names to a class that processes that plugin.
+        The class will take the Connection object as the argument to the constructor.
+        The class needs an authenticate method taking an authentication packet as
+        an argument.  For the dialog plugin, a prompt(echo, prompt) method can be used
+        (if no authenticate method) for returning a string from the user. (experimental)
+    :param server_public_key: SHA256 authenticaiton plugin public key value. (default: None)
+    :param db: Alias for database. (for compatibility to MySQLdb)
+    :param passwd: Alias for password. (for compatibility to MySQLdb)
+    :param binary_prefix: Add _binary prefix on bytes and bytearray. (default: False)
+
+    See `Connection <https://www.python.org/dev/peps/pep-0249/#connection-objects>`_ in the
+    specification.

+"""This module contains implementations of various third-party
+authentication schemes.
+
+All the classes in this file are class mixins designed to be used with
+the `tornado.web.RequestHandler` class.  They are used in two ways:
+
+* On a login handler, use methods such as ``authenticate_redirect()``,
+  ``authorize_redirect()``, and ``get_authenticated_user()`` to
+  establish the user's identity and store authentication tokens to your
+  database and/or cookies.
+* In non-login handlers, use methods such as ``facebook_request()``
+  or ``twitter_request()`` to use the authentication tokens to make
+  requests to the respective services.
+
+They all take slightly different arguments due to the fact all these
+services implement authentication and authorization slightly differently.
+See the individual service classes below for complete documentation.
+
+Example usage for Google OAuth:
+
+.. testcode::
+
+    class GoogleOAuth2LoginHandler(tornado.web.RequestHandler,
+                                   tornado.auth.GoogleOAuth2Mixin):
+        async def get(self):
+            if self.get_argument('code', False):
+                user = await self.get_authenticated_user(
+                    redirect_uri='http://your.site.com/auth/google',
+                    code=self.get_argument('code'))
+                # Save the user with e.g. set_secure_cookie
+            else:
+                await self.authorize_redirect(
+                    redirect_uri='http://your.site.com/auth/google',
+                    client_id=self.settings['google_oauth']['key'],
+                    scope=['profile', 'email'],
+                    response_type='code',
+                    extra_params={'approval_prompt': 'auto'})
+
+.. testoutput::

+
+
+.. versionchanged:: 4.0
+   All of the callback interfaces in this module are now guaranteed
+   to run their callback with an argument of ``None`` on error.
+   Previously some functions would do this while others would simply
+   terminate the request on their own.  This change also ensures that
+   errors are more consistently reported through the ``Future`` interfaces.

+"""Automatically restart the server when a source file is modified.
+
+Most applications should not access this module directly.  Instead,
+pass the keyword argument ``autoreload=True`` to the
+`tornado.web.Application` constructor (or ``debug=True``, which
+enables this setting and several others).  This will enable autoreload
+mode as well as checking for changes to templates and static
+resources.  Note that restarting is a destructive operation and any
+requests in progress will be aborted when the process restarts.  (If
+you want to disable autoreload while using other debug-mode features,
+pass both ``debug=True`` and ``autoreload=False``).
+
+This module can also be used as a command-line wrapper around scripts
+such as unit test runners.  See the `main` method for details.
+
+The command-line wrapper and Application debug modes can be used together.
+This combination is encouraged as the wrapper catches syntax errors and
+other import-time failures, while debug mode catches changes once
+the server has started.
+
+This module depends on `.IOLoop`, so it will not work in WSGI applications
+and Google App Engine.  It also will not work correctly when `.HTTPServer`'s
+multi-process mode is used.
+
+Reloading loses any Python interpreter command-line arguments (e.g. ``-u``)
+because it re-executes Python using ``sys.executable`` and ``sys.argv``.
+Additionally, modifying these variables will cause reloading to behave
+incorrectly.

+
+    This solves a nasty problem with Futures and Tasks that have an
+    exception set: if nobody asks for the exception, the exception is
+    never logged.  This violates the Zen of Python: 'Errors should
+    never pass silently.  Unless explicitly silenced.'
+
+    However, we don't want to log the exception as soon as
+    set_exception() is called: if the calling code is written
+    properly, it will get the exception and handle it properly.  But
+    we *do* want to log it if result() or exception() was never called
+    -- otherwise developers waste a lot of time wondering why their
+    buggy code fails silently.
+
+    An earlier attempt added a __del__() method to the Future class
+    itself, but this backfired because the presence of __del__()
+    prevents garbage collection from breaking cycles.  A way out of
+    this catch-22 is to avoid having a __del__() method on the Future
+    class itself, but instead to have a reference to a helper object
+    with a __del__() method that logs the traceback, where we ensure
+    that the helper object doesn't participate in cycles, and only the
+    Future has a reference to it.
+
+    The helper object is added when set_exception() is called.  When
+    the Future is collected, and the helper is present, the helper
+    object is also collected, and its __del__() method will log the
+    traceback.  When the Future's result() or exception() method is
+    called (and a helper object is present), it removes the the helper
+    object, after calling its clear() method to prevent it from
+    logging.
+
+    One downside is that we do a fair amount of work to extract the
+    traceback from the exception, even when it is never logged.  It
+    would seem cheaper to just store the exception object, but that
+    references the traceback, which references stack frames, which may
+    reference the Future, which references the _TracebackLogger, and
+    then the _TracebackLogger would be included in a cycle, which is
+    what we're trying to avoid!  As an optimization, we don't
+    immediately format the exception; we only do the work when
+    activate() is called, which call is delayed until after all the
+    Future's callbacks have run.  Since usually a Future has at least
+    one callback (typically set by 'yield From') and usually that
+    callback extracts the callback, thereby removing the need to
+    format the exception.
+
+    PS. I don't claim credit for this solution.  I first heard of it
+    in a discussion about closing files when they are collected.

+

+    to support better tracebacks on Python 2. To set an ``exc_info``

+       `tornado.concurrent.Future` is always a thread-unsafe ``Future``
+       with support for the ``exc_info`` methods.  Previously it would
+       be an alias for the thread-safe `concurrent.futures.Future`
+       if that package was available and fall back to the thread-unsafe
+       implementation if it was not.
+
+    .. versionchanged:: 4.1
+       If a `.Future` contains an error but that error is never observed
+       (by calling ``result()``, ``exception()``, or ``exc_info()``),
+       a stack trace will be logged when the `.Future` is garbage collected.
+       This normally indicates an error in the application, but in cases
+       where it results in undesired logging it may be necessary to
+       suppress the logging by ensuring that the exception is observed:
+       ``f.add_done_callback(lambda f: f.exception())``.
+
+    .. versionchanged:: 5.0
+
+       This class was previoiusly available under the name
+       ``TracebackFuture``. This name, which was deprecated since
+       version 4.0, has been removed. When `asyncio` is available
+       ``tornado.concurrent.Future`` is now an alias for
+       `asyncio.Future`. Like `asyncio.Future`, callbacks are now
+       always scheduled on the `.IOLoop` and are never run
+       synchronously.

+
+    This decorator was provided to ease the transition from

+    new code.
+
+    The wrapped function should take a ``callback`` keyword argument
+    and invoke it with one argument when it has finished.  To signal failure,
+    the function can simply raise an exception (which will be
+    captured by the `.StackContext` and passed along to the ``Future``).
+
+    From the caller's perspective, the callback argument is optional.
+    If one is given, it will be invoked when the function is complete
+    with ``Future.result()`` as an argument.  If the function fails, the
+    callback will not be run and an exception will be raised into the
+    surrounding `.StackContext`.
+
+    If no callback is given, the caller should use the ``Future`` to
+    wait for the function to complete (perhaps by yielding it in a
+    coroutine, or passing it to `.IOLoop.add_future`).

+"""``tornado.gen`` implements generator-based coroutines.
+
+.. note::
+
+   The "decorator and generator" approach in this module is a
+   precursor to native coroutines (using ``async def`` and ``await``)
+   which were introduced in Python 3.5. Applications that do not
+   require compatibility with older versions of Python should use
+   native coroutines instead. Some parts of this module are still
+   useful with native coroutines, notably `multi`, `sleep`,
+   `WaitIterator`, and `with_timeout`. Some of these functions have
+   counterparts in the `asyncio` module which may be used as well,
+   although the two may not necessarily be 100% compatible.
+
+Coroutines provide an easier way to work in an asynchronous
+environment than chaining callbacks. Code using coroutines is
+technically asynchronous, but it is written as a single generator
+instead of a collection of separate functions.
+
+For example, the following callback-based asynchronous handler:
+
+.. testcode::
+
+    class AsyncHandler(RequestHandler):
+        @asynchronous
+        def get(self):
+            http_client = AsyncHTTPClient()
+            http_client.fetch("http://example.com",
+                              callback=self.on_fetch)
+
+        def on_fetch(self, response):
+            do_something_with_response(response)
+            self.render("template.html")
+
+.. testoutput::
+   :hide:
+
+could be written with ``gen`` as:
+
+.. testcode::
+
+    class GenAsyncHandler(RequestHandler):
+        @gen.coroutine
+        def get(self):
+            http_client = AsyncHTTPClient()
+            response = yield http_client.fetch("http://example.com")
+            do_something_with_response(response)
+            self.render("template.html")
+
+.. testoutput::
+   :hide:
+
+Most asynchronous functions in Tornado return a `.Future`;
+yielding this object returns its ``Future.result``.
+
+You can also yield a list or dict of ``Futures``, which will be
+started at the same time and run in parallel; a list or dict of results will
+be returned when they are all finished:
+
+.. testcode::
+
+    @gen.coroutine
+    def get(self):
+        http_client = AsyncHTTPClient()
+        response1, response2 = yield [http_client.fetch(url1),
+                                      http_client.fetch(url2)]
+        response_dict = yield dict(response3=http_client.fetch(url3),
+                                   response4=http_client.fetch(url4))
+        response3 = response_dict['response3']
+        response4 = response_dict['response4']
+
+.. testoutput::
+   :hide:
+
+If the `~functools.singledispatch` library is available (standard in
+Python 3.4, available via the `singledispatch
+<https://pypi.python.org/pypi/singledispatch>`_ package on older
+versions), additional types of objects may be yielded. Tornado includes
+support for ``asyncio.Future`` and Twisted's ``Deferred`` class when
+``tornado.platform.asyncio`` and ``tornado.platform.twisted`` are imported.
+See the `convert_yielded` function to extend this mechanism.
+
+.. versionchanged:: 3.2
+   Dict support added.
+
+.. versionchanged:: 4.1
+   Support added for yielding ``asyncio`` Futures and Twisted Deferreds
+   via ``singledispatch``.

+"""Blocking and non-blocking HTTP client interfaces.
+
+This module defines a common interface shared by two implementations,
+``simple_httpclient`` and ``curl_httpclient``.  Applications may either
+instantiate their chosen implementation class directly or use the
+`AsyncHTTPClient` class from this module, which selects an implementation
+that can be overridden with the `AsyncHTTPClient.configure` method.
+
+The default implementation is ``simple_httpclient``, and this is expected
+to be suitable for most users' needs.  However, some applications may wish
+to switch to ``curl_httpclient`` for reasons such as the following:
+
+* ``curl_httpclient`` has some features not found in ``simple_httpclient``,
+  including support for HTTP proxies and the ability to use a specified
+  network interface.

+  features of HTTP.
+
+* ``curl_httpclient`` is faster.
+
+* ``curl_httpclient`` was the default prior to Tornado 2.0.
+
+Note that if you are using ``curl_httpclient``, it is highly
+recommended that you use a recent version of ``libcurl`` and
+``pycurl``.  Currently the minimum supported version of libcurl is
+7.22.0, and the minimum version of pycurl is 7.18.2.  It is highly
+recommended that your ``libcurl`` installation is built with
+asynchronous DNS resolver (threaded or c-ares), otherwise you may
+encounter various problems with request timeouts (for more
+information, see
+http://curl.haxx.se/libcurl/c/curl_easy_setopt.html#CURLOPTCONNECTTIMEOUTMS
+and comments in curl_httpclient.py).

+    r"""A non-blocking, single-threaded HTTP server.
+
+    A server is defined by a subclass of `.HTTPServerConnectionDelegate`,
+    or, for backwards compatibility, a callback that takes an
+    `.HTTPServerRequest` as an argument. The delegate is usually a
+    `tornado.web.Application`.
+
+    `HTTPServer` supports keep-alive connections by default
+    (automatically for HTTP/1.1, or for HTTP/1.0 when the client
+    requests ``Connection: keep-alive``).
+
+    If ``xheaders`` is ``True``, we support the
+    ``X-Real-Ip``/``X-Forwarded-For`` and
+    ``X-Scheme``/``X-Forwarded-Proto`` headers, which override the
+    remote IP and URI scheme/protocol for all requests.  These headers
+    are useful when running Tornado behind a reverse proxy or load
+    balancer.  The ``protocol`` argument can also be set to ``https``
+    if Tornado is run behind an SSL-decoding proxy that does not set one of
+    the supported ``xheaders``.
+
+    By default, when parsing the ``X-Forwarded-For`` header, Tornado will
+    select the last (i.e., the closest) address on the list of hosts as the
+    remote host IP address.  To select the next server in the chain, a list of
+    trusted downstream hosts may be passed as the ``trusted_downstream``
+    argument.  These hosts will be skipped when parsing the ``X-Forwarded-For``
+    header.
+
+    To make this server serve SSL traffic, send the ``ssl_options`` keyword
+    argument with an `ssl.SSLContext` object. For compatibility with older
+    versions of Python ``ssl_options`` may also be a dictionary of keyword
+    arguments for the `ssl.wrap_socket` method.::
+
+       ssl_ctx = ssl.create_default_context(ssl.Purpose.CLIENT_AUTH)
+       ssl_ctx.load_cert_chain(os.path.join(data_dir, "mydomain.crt"),
+                               os.path.join(data_dir, "mydomain.key"))
+       HTTPServer(application, ssl_options=ssl_ctx)
+
+    `HTTPServer` initialization follows one of three patterns (the
+    initialization methods are defined on `tornado.tcpserver.TCPServer`):
+
+    1. `~tornado.tcpserver.TCPServer.listen`: simple single-process::
+
+            server = HTTPServer(app)
+            server.listen(8888)
+            IOLoop.current().start()
+
+       In many cases, `tornado.web.Application.listen` can be used to avoid
+       the need to explicitly create the `HTTPServer`.
+
+    2. `~tornado.tcpserver.TCPServer.bind`/`~tornado.tcpserver.TCPServer.start`:
+       simple multi-process::
+
+            server = HTTPServer(app)
+            server.bind(8888)
+            server.start(0)  # Forks multiple sub-processes
+            IOLoop.current().start()
+
+       When using this interface, an `.IOLoop` must *not* be passed
+       to the `HTTPServer` constructor.  `~.TCPServer.start` will always start
+       the server on the default singleton `.IOLoop`.
+
+    3. `~tornado.tcpserver.TCPServer.add_sockets`: advanced multi-process::
+
+            sockets = tornado.netutil.bind_sockets(8888)
+            tornado.process.fork_processes(0)
+            server = HTTPServer(app)
+            server.add_sockets(sockets)
+            IOLoop.current().start()
+
+       The `~.TCPServer.add_sockets` interface is more complicated,
+       but it can be used with `tornado.process.fork_processes` to
+       give you more flexibility in when the fork happens.
+       `~.TCPServer.add_sockets` can also be used in single-process
+       servers if you want to create your listening sockets in some
+       way other than `tornado.netutil.bind_sockets`.
+
+    .. versionchanged:: 4.0
+       Added ``decompress_request``, ``chunk_size``, ``max_header_size``,
+       ``idle_connection_timeout``, ``body_timeout``, ``max_body_size``

+    By default, a newly-constructed `IOLoop` becomes the thread's current

+    not try to become current.
+
+    In general, an `IOLoop` cannot survive a fork or be shared across
+    processes in any way. When multiple processes are being used, each
+    process should create its own `IOLoop`, which also implies that
+    any objects which depend on the `IOLoop` (such as
+    `.AsyncHTTPClient`) must also be created in the child processes.
+    As a guideline, anything that starts processes (including the

+    early as possible, ideally the first thing the application does
+    after loading its configuration in ``main()``.

+"""Translation methods for generating localized strings.
+
+To load a locale and generate a translated string::
+
+    user_locale = tornado.locale.get("es_LA")
+    print(user_locale.translate("Sign out"))
+
+`tornado.locale.get()` returns the closest matching locale, not necessarily the
+specific locale you requested. You can support pluralization with
+additional arguments to `~Locale.translate()`, e.g.::
+
+    people = [...]
+    message = user_locale.translate(
+        "%(list)s is online", "%(list)s are online", len(people))
+    print(message % {"list": user_locale.list(people)})
+
+The first string is chosen if ``len(people) == 1``, otherwise the second
+string is chosen.
+
+Applications should call one of `load_translations` (which uses a simple
+CSV format) or `load_gettext_translations` (which uses the ``.mo`` format
+supported by `gettext` and related tools).  If neither method is called,
+the `Locale.translate` method will simply return the original string.

+"""A command line parsing module that lets modules define their own options.
+
+This module is inspired by Google's `gflags
+<https://github.com/google/python-gflags>`_. The primary difference
+with libraries such as `argparse` is that a global registry is used so
+that options may be defined in any module (it also enables
+`tornado.log` by default). The rest of Tornado does not depend on this
+module, so feel free to use `argparse` or other configuration
+libraries if you prefer them.
+
+Options must be defined with `tornado.options.define` before use,
+generally at the top level of a module. The options are then
+accessible as attributes of `tornado.options.options`::
+
+    # myapp/db.py
+    from tornado.options import define, options
+
+    define("mysql_host", default="127.0.0.1:3306", help="Main user DB")
+    define("memcache_hosts", default="127.0.0.1:11011", multiple=True,
+           help="Main user memcache servers")
+
+    def connect():
+        db = database.Connection(options.mysql_host)
+        ...
+
+    # myapp/server.py
+    from tornado.options import define, options
+
+    define("port", default=8080, help="port to listen on")
+
+    def start_server():
+        app = make_app()
+        app.listen(options.port)
+
+The ``main()`` method of your application does not need to be aware of all of
+the options used throughout your program; they are all automatically loaded
+when the modules are loaded.  However, all modules that define options
+must have been imported before the command line is parsed.
+
+Your ``main()`` method can parse the command line or parse a config file with
+either `parse_command_line` or `parse_config_file`::
+
+    import myapp.db, myapp.server
+    import tornado.options
+
+    if __name__ == '__main__':
+        tornado.options.parse_command_line()
+        # or
+        tornado.options.parse_config_file("/etc/server.conf")
+
+.. note::
+
+   When using multiple ``parse_*`` functions, pass ``final=False`` to all
+   but the last one, or side effects may occur twice (in particular,
+   this can result in log messages being doubled).
+
+`tornado.options.options` is a singleton instance of `OptionParser`, and
+the top-level functions in this module (`define`, `parse_command_line`, etc)
+simply call methods on it.  You may create additional `OptionParser`
+instances to define isolated sets of options, such as for subcommands.
+
+.. note::
+
+   By default, several options are defined that will configure the
+   standard `logging` module when `parse_command_line` or `parse_config_file`
+   are called.  If you want Tornado to leave the logging configuration
+   alone so you can manage it yourself, either pass ``--logging=none``
+   on the command line or do the following to disable it in code::
+
+       from tornado.options import options, parse_command_line
+       options.logging = None
+       parse_command_line()
+
+.. versionchanged:: 4.3
+   Dashes and underscores are fully interchangeable in option names;
+   options can be defined, set, and read with any mix of the two.
+   Dashes are typical for command-line usage while config files require
+   underscores.

+"""Flexible routing implementation.
+
+Tornado routes HTTP requests to appropriate handlers using `Router`
+class implementations. The `tornado.web.Application` class is a
+`Router` implementation and may be used directly, or the classes in
+this module may be used for additional flexibility. The `RuleRouter`
+class can match on more criteria than `.Application`, or the `Router`
+interface can be subclassed for maximum customization.
+
+`Router` interface extends `~.httputil.HTTPServerConnectionDelegate`
+to provide additional routing capabilities. This also means that any
+`Router` implementation can be used directly as a ``request_callback``
+for `~.httpserver.HTTPServer` constructor.
+
+`Router` subclass must implement a ``find_handler`` method to provide
+a suitable `~.httputil.HTTPMessageDelegate` instance to handle the
+request:
+
+.. code-block:: python
+
+    class CustomRouter(Router):
+        def find_handler(self, request, **kwargs):
+            # some routing logic providing a suitable HTTPMessageDelegate instance
+            return MessageDelegate(request.connection)
+
+    class MessageDelegate(HTTPMessageDelegate):
+        def __init__(self, connection):
+            self.connection = connection
+
+        def finish(self):
+            self.connection.write_headers(
+                ResponseStartLine("HTTP/1.1", 200, "OK"),
+                HTTPHeaders({"Content-Length": "2"}),
+                b"OK")
+            self.connection.finish()
+
+    router = CustomRouter()
+    server = HTTPServer(router)
+
+The main responsibility of `Router` implementation is to provide a
+mapping from a request to `~.httputil.HTTPMessageDelegate` instance
+that will handle this request. In the example above we can see that
+routing is possible even without instantiating an `~.web.Application`.
+
+For routing to `~.web.RequestHandler` implementations we need an
+`~.web.Application` instance. `~.web.Application.get_handler_delegate`
+provides a convenient way to create `~.httputil.HTTPMessageDelegate`
+for a given request and `~.web.RequestHandler`.
+
+Here is a simple example of how we can we route to
+`~.web.RequestHandler` subclasses by HTTP method:
+
+.. code-block:: python
+
+    resources = {}
+
+    class GetResource(RequestHandler):
+        def get(self, path):
+            if path not in resources:
+                raise HTTPError(404)
+
+            self.finish(resources[path])
+
+    class PostResource(RequestHandler):
+        def post(self, path):
+            resources[path] = self.request.body
+
+    class HTTPMethodRouter(Router):
+        def __init__(self, app):
+            self.app = app
+
+        def find_handler(self, request, **kwargs):
+            handler = GetResource if request.method == "GET" else PostResource
+            return self.app.get_handler_delegate(request, handler, path_args=[request.path])
+
+    router = HTTPMethodRouter(Application())
+    server = HTTPServer(router)
+
+`ReversibleRouter` interface adds the ability to distinguish between
+the routes and reverse them to the original urls using route's name
+and additional arguments. `~.web.Application` is itself an
+implementation of `ReversibleRouter` class.
+
+`RuleRouter` and `ReversibleRuleRouter` are implementations of
+`Router` and `ReversibleRouter` interfaces and can be used for
+creating rule-based routing configurations.
+
+Rules are instances of `Rule` class. They contain a `Matcher`, which
+provides the logic for determining whether the rule is a match for a
+particular request and a target, which can be one of the following.
+
+1) An instance of `~.httputil.HTTPServerConnectionDelegate`:
+
+.. code-block:: python
+
+    router = RuleRouter([
+        Rule(PathMatches("/handler"), ConnectionDelegate()),
+        # ... more rules
+    ])
+
+    class ConnectionDelegate(HTTPServerConnectionDelegate):
+        def start_request(self, server_conn, request_conn):
+            return MessageDelegate(request_conn)
+
+2) A callable accepting a single argument of `~.httputil.HTTPServerRequest` type:
+
+.. code-block:: python
+
+    router = RuleRouter([
+        Rule(PathMatches("/callable"), request_callable)
+    ])
+
+    def request_callable(request):
+        request.write(b"HTTP/1.1 200 OK\\r\\nContent-Length: 2\\r\\n\\r\\nOK")
+        request.finish()
+
+3) Another `Router` instance:
+
+.. code-block:: python
+
+    router = RuleRouter([
+        Rule(PathMatches("/router.*"), CustomRouter())
+    ])
+
+Of course a nested `RuleRouter` or a `~.web.Application` is allowed:
+
+.. code-block:: python
+
+    router = RuleRouter([
+        Rule(HostMatches("example.com"), RuleRouter([
+            Rule(PathMatches("/app1/.*"), Application([(r"/app1/handler", Handler)]))),
+        ]))
+    ])
+
+    server = HTTPServer(router)
+
+In the example below `RuleRouter` is used to route between applications:
+
+.. code-block:: python
+
+    app1 = Application([
+        (r"/app1/handler", Handler1),
+        # other handlers ...
+    ])
+
+    app2 = Application([
+        (r"/app2/handler", Handler2),
+        # other handlers ...
+    ])
+
+    router = RuleRouter([
+        Rule(PathMatches("/app1.*"), app1),
+        Rule(PathMatches("/app2.*"), app2)
+    ])
+
+    server = HTTPServer(router)
+
+For more information on application-level routing see docs for `~.web.Application`.

+"""`StackContext` allows applications to maintain threadlocal-like state
+that follows execution as it moves to other execution contexts.
+
+The motivating examples are to eliminate the need for explicit
+``async_callback`` wrappers (as in `tornado.web.RequestHandler`), and to
+allow some additional context to be kept for logging.
+
+This is slightly magic, but it's an extension of the idea that an
+exception handler is a kind of stack-local state and when that stack
+is suspended and resumed in a new context that state needs to be
+preserved.  `StackContext` shifts the burden of restoring that state
+from each call site (e.g.  wrapping each `.AsyncHTTPClient` callback
+in ``async_callback``) to the mechanisms that transfer control from
+one context to another (e.g. `.AsyncHTTPClient` itself, `.IOLoop`,
+thread pools, etc).
+
+Example usage::
+
+    @contextlib.contextmanager
+    def die_on_error():
+        try:
+            yield
+        except Exception:
+            logging.error("exception in asynchronous operation",exc_info=True)
+            sys.exit(1)
+
+    with StackContext(die_on_error):
+        # Any exception thrown here *or in callback and its descendants*
+        # will cause the process to exit instead of spinning endlessly
+        # in the ioloop.
+        http_client.fetch(url, callback)
+    ioloop.start()
+
+Most applications shouldn't have to work with `StackContext` directly.
+Here are a few rules of thumb for when it's necessary:
+
+* If you're writing an asynchronous library that doesn't rely on a
+  stack_context-aware library like `tornado.ioloop` or `tornado.iostream`
+  (for example, if you're writing a thread pool), use
+  `.stack_context.wrap()` before any asynchronous operations to capture the
+  stack context from where the operation was started.
+
+* If you're writing an asynchronous library that has some shared
+  resources (such as a connection pool), create those shared resources
+  within a ``with stack_context.NullContext():`` block.  This will prevent
+  ``StackContexts`` from leaking from one request to another.
+
+* If you want to write something like an exception handler that will
+  persist across asynchronous calls, create a new `StackContext` (or
+  `ExceptionStackContext`), and make your asynchronous calls in a ``with``
+  block that references your `StackContext`.
+
+.. deprecated:: 5.1
+
+   The ``stack_context`` package is deprecated and will be removed in
+   Tornado 6.0.

+
+    To use `TCPServer`, define a subclass which overrides the `handle_stream`
+    method. For example, a simple echo server could be defined like this::
+
+      from tornado.tcpserver import TCPServer
+      from tornado.iostream import StreamClosedError
+      from tornado import gen
+
+      class EchoServer(TCPServer):

+                  except StreamClosedError:
+                      break
+
+    To make this server serve SSL traffic, send the ``ssl_options`` keyword
+    argument with an `ssl.SSLContext` object. For compatibility with older
+    versions of Python ``ssl_options`` may also be a dictionary of keyword
+    arguments for the `ssl.wrap_socket` method.::
+
+       ssl_ctx = ssl.create_default_context(ssl.Purpose.CLIENT_AUTH)
+       ssl_ctx.load_cert_chain(os.path.join(data_dir, "mydomain.crt"),
+                               os.path.join(data_dir, "mydomain.key"))
+       TCPServer(ssl_options=ssl_ctx)
+
+    `TCPServer` initialization follows one of three patterns:
+
+    1. `listen`: simple single-process::
+
+            server = TCPServer()
+            server.listen(8888)
+            IOLoop.current().start()
+
+    2. `bind`/`start`: simple multi-process::
+
+            server = TCPServer()
+            server.bind(8888)
+            server.start(0)  # Forks multiple sub-processes
+            IOLoop.current().start()
+
+       When using this interface, an `.IOLoop` must *not* be passed
+       to the `TCPServer` constructor.  `start` will always start
+       the server on the default singleton `.IOLoop`.
+
+    3. `add_sockets`: advanced multi-process::
+
+            sockets = bind_sockets(8888)
+            tornado.process.fork_processes(0)
+            server = TCPServer()
+            server.add_sockets(sockets)
+            IOLoop.current().start()
+
+       The `add_sockets` interface is more complicated, but it can be
+       used with `tornado.process.fork_processes` to give you more
+       flexibility in when the fork happens.  `add_sockets` can
+       also be used in single-process servers if you want to create
+       your listening sockets in some way other than
+       `~tornado.netutil.bind_sockets`.

+"""A simple template system that compiles templates to Python code.
+
+Basic usage looks like::
+
+    t = template.Template("<html>{{ myvalue }}</html>")
+    print(t.generate(myvalue="XXX"))
+
+`Loader` is a class that loads templates from a root directory and caches
+the compiled templates::
+
+    loader = template.Loader("/home/btaylor")
+    print(loader.load("test.html").generate(myvalue="XXX"))
+
+We compile all templates to raw Python. Error-reporting is currently... uh,
+interesting. Syntax for the templates::
+
+    ### base.html
+    <html>
+      <head>
+        <title>{% block title %}Default title{% end %}</title>
+      </head>
+      <body>
+        <ul>
+          {% for student in students %}
+            {% block student %}
+              <li>{{ escape(student.name) }}</li>
+            {% end %}
+          {% end %}
+        </ul>
+      </body>
+    </html>
+
+    ### bold.html
+    {% extends "base.html" %}
+
+    {% block title %}A bolder title{% end %}
+
+    {% block student %}
+      <li><span style="bold">{{ escape(student.name) }}</span></li>
+    {% end %}
+
+Unlike most other template systems, we do not put any restrictions on the
+expressions you can include in your statements. ``if`` and ``for`` blocks get
+translated exactly into Python, so you can do complex expressions like::
+
+   {% for student in [p for p in people if p.student and p.age > 23] %}
+     <li>{{ escape(student.name) }}</li>
+   {% end %}
+
+Translating directly to Python means you can apply functions to expressions
+easily, like the ``escape()`` function in the examples above. You can pass
+functions in to your template just like any other variable
+(In a `.RequestHandler`, override `.RequestHandler.get_template_namespace`)::
+
+   ### Python code
+   def add(x, y):
+      return x + y
+   template.execute(add=add)
+
+   ### The template
+   {{ add(1, 2) }}
+
+We provide the functions `escape() <.xhtml_escape>`, `.url_escape()`,
+`.json_encode()`, and `.squeeze()` to all templates by default.
+
+Typical applications do not create `Template` or `Loader` instances by
+hand, but instead use the `~.RequestHandler.render` and
+`~.RequestHandler.render_string` methods of
+`tornado.web.RequestHandler`, which load templates automatically based
+on the ``template_path`` `.Application` setting.
+
+Variable names beginning with ``_tt_`` are reserved by the template
+system and should not be used by application code.
+
+Syntax Reference
+----------------
+
+Template expressions are surrounded by double curly braces: ``{{ ... }}``.
+The contents may be any python expression, which will be escaped according
+to the current autoescape setting and inserted into the output.  Other
+template directives use ``{% %}``.
+
+To comment out a section so that it is omitted from the output, surround it
+with ``{# ... #}``.
+
+These tags may be escaped as ``{{!``, ``{%!``, and ``{#!``
+if you need to include a literal ``{{``, ``{%``, or ``{#`` in the output.
+
+
+``{% apply *function* %}...{% end %}``
+    Applies a function to the output of all template code between ``apply``
+    and ``end``::
+
+        {% apply linkify %}{{name}} said: {{message}}{% end %}
+
+    Note that as an implementation detail apply blocks are implemented
+    as nested functions and thus may interact strangely with variables
+    set via ``{% set %}``, or the use of ``{% break %}`` or ``{% continue %}``
+    within loops.
+
+``{% autoescape *function* %}``
+    Sets the autoescape mode for the current file.  This does not affect
+    other files, even those referenced by ``{% include %}``.  Note that
+    autoescaping can also be configured globally, at the `.Application`
+    or `Loader`.::
+
+        {% autoescape xhtml_escape %}
+        {% autoescape None %}
+
+``{% block *name* %}...{% end %}``
+    Indicates a named, replaceable block for use with ``{% extends %}``.
+    Blocks in the parent template will be replaced with the contents of
+    the same-named block in a child template.::
+
+        <!-- base.html -->
+        <title>{% block title %}Default title{% end %}</title>
+
+        <!-- mypage.html -->
+        {% extends "base.html" %}
+        {% block title %}My page title{% end %}
+
+``{% comment ... %}``
+    A comment which will be removed from the template output.  Note that
+    there is no ``{% end %}`` tag; the comment goes from the word ``comment``
+    to the closing ``%}`` tag.
+
+``{% extends *filename* %}``
+    Inherit from another template.  Templates that use ``extends`` should
+    contain one or more ``block`` tags to replace content from the parent
+    template.  Anything in the child template not contained in a ``block``
+    tag will be ignored.  For an example, see the ``{% block %}`` tag.
+
+``{% for *var* in *expr* %}...{% end %}``
+    Same as the python ``for`` statement.  ``{% break %}`` and
+    ``{% continue %}`` may be used inside the loop.
+
+``{% from *x* import *y* %}``
+    Same as the python ``import`` statement.
+
+``{% if *condition* %}...{% elif *condition* %}...{% else %}...{% end %}``
+    Conditional statement - outputs the first section whose condition is
+    true.  (The ``elif`` and ``else`` sections are optional)
+
+``{% import *module* %}``
+    Same as the python ``import`` statement.
+
+``{% include *filename* %}``
+    Includes another template file.  The included file can see all the local
+    variables as if it were copied directly to the point of the ``include``
+    directive (the ``{% autoescape %}`` directive is an exception).
+    Alternately, ``{% module Template(filename, **kwargs) %}`` may be used
+    to include another template with an isolated namespace.
+
+``{% module *expr* %}``
+    Renders a `~tornado.web.UIModule`.  The output of the ``UIModule`` is
+    not escaped::
+
+        {% module Template("foo.html", arg=42) %}
+
+    ``UIModules`` are a feature of the `tornado.web.RequestHandler`
+    class (and specifically its ``render`` method) and will not work
+    when the template system is used on its own in other contexts.
+
+``{% raw *expr* %}``
+    Outputs the result of the given expression without autoescaping.
+
+``{% set *x* = *y* %}``
+    Sets a local variable.
+
+``{% try %}...{% except %}...{% else %}...{% finally %}...{% end %}``
+    Same as the python ``try`` statement.
+
+``{% while *condition* %}... {% end %}``
+    Same as the python ``while`` statement.  ``{% break %}`` and
+    ``{% continue %}`` may be used inside the loop.
+
+``{% whitespace *mode* %}``
+    Sets the whitespace mode for the remainder of the current file
+    (or until the next ``{% whitespace %}`` directive). See
+    `filter_whitespace` for available options. New in Tornado 4.3.

+
+    The unittest framework is synchronous, so the test must be
+    complete by the time the test method returns. This means that
+    asynchronous code cannot be used in quite the same way as usual
+    and must be adapted to fit. To write your tests with coroutines,
+    decorate your test methods with `tornado.testing.gen_test` instead
+    of `tornado.gen.coroutine`.
+
+    This class also provides the (deprecated) `stop()` and `wait()`
+    methods for a more manual style of testing. The test method itself
+    must call ``self.wait()``, and asynchronous callbacks should call
+    ``self.stop()`` to signal completion.
+
+    By default, a new `.IOLoop` is constructed for each test and is available
+    as ``self.io_loop``.  If the code being tested requires a
+    global `.IOLoop`, subclasses should override `get_new_ioloop` to return it.
+
+    The `.IOLoop`'s ``start`` and ``stop`` methods should not be
+    called directly.  Instead, use `self.stop <stop>` and `self.wait
+    <wait>`.  Arguments passed to ``self.stop`` are returned from
+    ``self.wait``.  It is possible to have multiple ``wait``/``stop``
+    cycles in the same test.

+
+        # This test uses coroutine style.

+"""``tornado.web`` provides a simple web framework with asynchronous
+features that allow it to scale to large numbers of open connections,
+making it ideal for `long polling
+<http://en.wikipedia.org/wiki/Push_technology#Long_polling>`_.
+
+Here is a simple "Hello, world" example app:
+
+.. testcode::
+
+    import tornado.ioloop
+    import tornado.web
+
+    class MainHandler(tornado.web.RequestHandler):
+        def get(self):
+            self.write("Hello, world")
+
+    if __name__ == "__main__":
+        application = tornado.web.Application([
+            (r"/", MainHandler),
+        ])
+        application.listen(8888)
+        tornado.ioloop.IOLoop.current().start()
+
+.. testoutput::
+   :hide:
+
+
+See the :doc:`guide` for additional information.
+
+Thread-safety notes
+-------------------
+
+In general, methods on `RequestHandler` and elsewhere in Tornado are
+not thread-safe. In particular, methods such as
+`~RequestHandler.write()`, `~RequestHandler.finish()`, and
+`~RequestHandler.flush()` must only be called from the main thread. If
+you use multiple threads it is important to use `.IOLoop.add_callback`
+to transfer control back to the main thread before finishing the
+request, or to limit your use of other threads to
+`.IOLoop.run_in_executor` and ensure that your callbacks running in
+the executor do not refer to Tornado objects.

+    """A collection of request handlers that make up a web application.
+
+    Instances of this class are callable and can be passed directly to
+    HTTPServer to serve the application::
+
+        application = web.Application([
+            (r"/", MainPageHandler),
+        ])
+        http_server = httpserver.HTTPServer(application)
+        http_server.listen(8080)
+        ioloop.IOLoop.current().start()
+
+    The constructor for this class takes in a list of `~.routing.Rule`
+    objects or tuples of values corresponding to the arguments of
+    `~.routing.Rule` constructor: ``(matcher, target, [target_kwargs], [name])``,
+    the values in square brackets being optional. The default matcher is
+    `~.routing.PathMatches`, so ``(regexp, target)`` tuples can also be used
+    instead of ``(PathMatches(regexp), target)``.
+
+    A common routing target is a `RequestHandler` subclass, but you can also
+    use lists of rules as a target, which create a nested routing configuration::
+
+        application = web.Application([
+            (HostMatches("example.com"), [
+                (r"/", MainPageHandler),
+                (r"/feed", FeedHandler),
+            ]),
+        ])
+
+    In addition to this you can use nested `~.routing.Router` instances,
+    `~.httputil.HTTPMessageDelegate` subclasses and callables as routing targets
+    (see `~.routing` module docs for more information).
+
+    When we receive requests, we iterate over the list in order and
+    instantiate an instance of the first request class whose regexp
+    matches the request path. The request class can be specified as
+    either a class object or a (fully-qualified) name.
+
+    A dictionary may be passed as the third element (``target_kwargs``)
+    of the tuple, which will be used as keyword arguments to the handler's
+    constructor and `~RequestHandler.initialize` method. This pattern
+    is used for the `StaticFileHandler` in this example (note that a
+    `StaticFileHandler` can be installed automatically with the
+    static_path setting described below)::
+
+        application = web.Application([
+            (r"/static/(.*)", web.StaticFileHandler, {"path": "/var/www"}),
+        ])
+
+    We support virtual hosts with the `add_handlers` method, which takes in
+    a host regular expression as the first argument::
+
+        application.add_handlers(r"www\.myhost\.com", [
+            (r"/article/([0-9]+)", ArticleHandler),
+        ])
+
+    If there's no match for the current request's host, then ``default_host``
+    parameter value is matched against host regular expressions.
+
+
+    .. warning::
+
+       Applications that do not use TLS may be vulnerable to :ref:`DNS
+       rebinding <dnsrebinding>` attacks. This attack is especially
+       relevant to applications that only listen on ``127.0.0.1` or
+       other private networks. Appropriate host patterns must be used
+       (instead of the default of ``r'.*'``) to prevent this risk. The
+       ``default_host`` argument must not be used in applications that
+       may be vulnerable to DNS rebinding.
+
+    You can serve static files by sending the ``static_path`` setting
+    as a keyword argument. We will serve those files from the
+    ``/static/`` URI (this is configurable with the
+    ``static_url_prefix`` setting), and we will serve ``/favicon.ico``
+    and ``/robots.txt`` from the same directory.  A custom subclass of
+    `StaticFileHandler` can be specified with the
+    ``static_handler_class`` setting.

+
+    A `StaticFileHandler` is configured automatically if you pass the
+    ``static_path`` keyword argument to `Application`.  This handler
+    can be customized with the ``static_url_prefix``, ``static_handler_class``,
+    and ``static_handler_args`` settings.
+
+    To map an additional path to this handler for a static data directory
+    you would add a line to your application like::
+
+        application = web.Application([
+            (r"/content/(.*)", web.StaticFileHandler, {"path": "/var/www"}),
+        ])
+
+    The handler constructor requires a ``path`` argument, which specifies the
+    local root directory of the content to be served.
+
+    Note that a capture group in the regex is required to parse the value for
+    the ``path`` argument to the get() method (different than the constructor
+    argument above); see `URLSpec` for details.
+
+    To serve a file like ``index.html`` automatically when a directory is
+    requested, set ``static_handler_args=dict(default_filename="index.html")``
+    in your application settings, or add ``default_filename`` as an initializer
+    argument for your ``StaticFileHandler``.
+
+    To maximize the effectiveness of browser caching, this class supports
+    versioned urls (by default using the argument ``?v=``).  If a version
+    is given, we instruct the browser to cache this file indefinitely.
+    `make_static_url` (also available as `RequestHandler.static_url`) can
+    be used to construct a versioned url.
+
+    This handler is intended primarily for use in development and light-duty
+    file serving; for heavy traffic it will be more efficient to use
+    a dedicated static file server (such as nginx or Apache).  We support
+    the HTTP ``Accept-Ranges`` mechanism to return partial content (because
+    some browsers require this functionality to be present to seek in
+    HTML5 audio or video).
+
+    **Subclassing notes**
+
+    This class is designed to be extensible by subclassing, but because
+    of the way static urls are generated with class methods rather than
+    instance methods, the inheritance patterns are somewhat unusual.
+    Be sure to use the ``@classmethod`` decorator when overriding a
+    class method.  Instance methods may use the attributes ``self.path``
+    ``self.absolute_path``, and ``self.modified``.
+
+    Subclasses should only override methods discussed in this section;
+    overriding other methods is error-prone.  Overriding
+    ``StaticFileHandler.get`` is particularly problematic due to the
+    tight coupling with ``compute_etag`` and other methods.
+
+    To change the way static urls are generated (e.g. to match the behavior
+    of another server or CDN), override `make_static_url`, `parse_url_path`,
+    `get_cache_time`, and/or `get_version`.
+
+    To replace all interaction with the filesystem (e.g. to serve
+    static content from a database), override `get_content`,
+    `get_content_size`, `get_modified_time`, `get_absolute_path`, and
+    `validate_absolute_path`.
+
+    .. versionchanged:: 3.1
+       Many of the methods for subclasses were added in Tornado 3.1.

+"""Implementation of the WebSocket protocol.
+
+`WebSockets <http://dev.w3.org/html5/websockets/>`_ allow for bidirectional
+communication between the browser and server.
+
+WebSockets are supported in the current versions of all major browsers,
+although older versions that do not support WebSockets are still in use
+(refer to http://caniuse.com/websockets for details).
+
+This module implements the final version of the WebSocket protocol as
+defined in `RFC 6455 <http://tools.ietf.org/html/rfc6455>`_.  Certain
+browser versions (notably Safari 5.x) implemented an earlier draft of
+the protocol (known as "draft 76") and are not compatible with this module.
+
+.. versionchanged:: 4.0
+   Removed support for the draft 76 protocol version.

+
+    Override `on_message` to handle incoming messages, and use
+    `write_message` to send messages to the client. You can also
+    override `open` and `on_close` to handle opened and closed
+    connections.
+
+    Custom upgrade response headers can be sent by overriding
+    `~tornado.web.RequestHandler.set_default_headers` or
+    `~tornado.web.RequestHandler.prepare`.
+
+    See http://dev.w3.org/html5/websockets/ for details on the
+    JavaScript interface.  The protocol is specified at
+    http://tools.ietf.org/html/rfc6455.
+
+    Here is an example WebSocket handler that echos back all received messages
+    back to the client:
+
+    .. testcode::
+
+      class EchoWebSocket(tornado.websocket.WebSocketHandler):
+          def open(self):
+              print("WebSocket opened")
+
+          def on_message(self, message):
+              self.write_message(u"You said: " + message)
+
+          def on_close(self):
+              print("WebSocket closed")
+
+    .. testoutput::
+       :hide:
+
+    WebSockets are not standard HTTP connections. The "handshake" is
+    HTTP, but after the handshake, the protocol is
+    message-based. Consequently, most of the Tornado HTTP facilities
+    are not available in handlers of this type. The only communication
+    methods available to you are `write_message()`, `ping()`, and
+    `close()`. Likewise, your request handler class should implement
+    `open()` method rather than ``get()`` or ``post()``.
+
+    If you map the handler above to ``/websocket`` in your application, you can
+    invoke it in JavaScript with::
+
+      var ws = new WebSocket("ws://localhost:8888/websocket");
+      ws.onopen = function() {
+         ws.send("Hello, world");
+      };
+      ws.onmessage = function (evt) {
+         alert(evt.data);
+      };
+
+    This script pops up an alert box that says "You said: Hello, world".
+
+    Web browsers allow any site to open a websocket connection to any other,
+    instead of using the same-origin policy that governs other network
+    access from javascript.  This can be surprising and is a potential
+    security hole, so since Tornado 4.0 `WebSocketHandler` requires
+    applications that wish to receive cross-origin websockets to opt in
+    by overriding the `~WebSocketHandler.check_origin` method (see that
+    method's docs for details).  Failure to do so is the most likely
+    cause of 403 errors when making a websocket connection.
+
+    When using a secure websocket connection (``wss://``) with a self-signed
+    certificate, the connection from a browser may fail because it wants
+    to show the "accept this certificate" dialog but has nowhere to show it.
+    You must first visit a regular HTML page using the same certificate
+    to accept it before the websocket connection will succeed.
+
+    If the application setting ``websocket_ping_interval`` has a non-zero
+    value, a ping will be sent periodically, and the connection will be
+    closed if a response is not received before the ``websocket_ping_timeout``.
+
+    Messages larger than the ``websocket_max_message_size`` application setting
+    (default 10MiB) will not be accepted.
+
+    .. versionchanged:: 4.5
+       Added ``websocket_ping_interval``, ``websocket_ping_timeout``, and
+       ``websocket_max_message_size``.

+"""WSGI support for the Tornado web framework.
+
+WSGI is the Python standard for web servers, and allows for interoperability
+between Tornado and other Python web frameworks and servers.  This module
+provides WSGI support in two ways:
+
+* `WSGIAdapter` converts a `tornado.web.Application` to the WSGI application
+  interface.  This is useful for running a Tornado app on another
+  HTTP server, such as Google App Engine.  See the `WSGIAdapter` class
+  documentation for limitations that apply.
+* `WSGIContainer` lets you run other WSGI applications and frameworks on the
+  Tornado HTTP server.  For example, with this class you can mix Django
+  and Tornado handlers in a single server.

+

+       is based on single-threaded asynchronous execution.  This means that
+       running a WSGI app with Tornado's `WSGIContainer` is *less scalable*

+       ``gunicorn`` or ``uwsgi``.  Use `WSGIContainer` only when there are
+       benefits to combining Tornado and WSGI in the same process that
+       outweigh the reduced scalability.
+
+    Wrap a WSGI function in a `WSGIContainer` and pass it to `.HTTPServer` to
+    run it. For example::
+
+        def simple_app(environ, start_response):
