+~~~~~~~~
+
+Werkzeug is the Swiss Army knife of Python web development.
+
+It provides useful classes and functions for any WSGI application to
+make the life of a Python web developer much easier. All of the provided
+classes are independent from each other so you can mix it with any other
+library.

+    ~~~~~~~~~~~~~~~~~~~~~~
+
+    The main problem with dynamic Web sites is, well, they're dynamic.  Each
+    time a user requests a page, the webserver executes a lot of code, queries
+    the database, renders templates until the visitor gets the page he sees.
+
+    This is a lot more expensive than just loading a file from the file system
+    and sending it to the visitor.
+
+    For most Web applications, this overhead isn't a big deal but once it
+    becomes, you will be glad to have a cache system in place.
+
+    How Caching Works
+    =================
+
+    Caching is pretty simple.  Basically you have a cache object lurking around
+    somewhere that is connected to a remote cache or the file system or
+    something else.  When the request comes in you check if the current page
+    is already in the cache and if so, you're returning it from the cache.
+    Otherwise you generate the page and put it into the cache. (Or a fragment
+    of the page, you don't have to cache the full thing)
+
+    Here is a simple example of how to cache a sidebar for 5 minutes::
+
+        def get_sidebar(user):
+            identifier = 'sidebar_for/user%d' % user.id
+            value = cache.get(identifier)
+            if value is not None:
+                return value
+            value = generate_sidebar_for(user=user)
+            cache.set(identifier, value, timeout=60 * 5)
+            return value
+
+    Creating a Cache Object
+    =======================
+
+    To create a cache object you just import the cache system of your choice
+    from the cache module and instantiate it.  Then you can start working
+    with that object:
+
+    >>> from werkzeug.contrib.cache import SimpleCache
+    >>> c = SimpleCache()
+    >>> c.set("foo", "value")
+    >>> c.get("foo")
+    'value'
+    >>> c.get("missing") is None
+    True
+
+    Please keep in mind that you have to create the cache and put it somewhere
+    you have access to it (either as a module global you can import or you just
+    put it into your WSGI application).

+    To convert an iterator into a stream all you have to do is to pass it
+    directly to the :class:`IterIO` constructor.  In this example we pass it
+    a newly created generator::
+
+        def foo():
+            yield "something\n"
+            yield "otherthings"
+        stream = IterIO(foo())
+        print stream.read()         # read the whole iterator
+
+    The other way round works a bit different because we have to ensure that
+    the code execution doesn't take place yet.  An :class:`IterIO` call with a
+    callable as first argument does two things.  The function itself is passed
+    an :class:`IterIO` stream it can feed.  The object returned by the
+    :class:`IterIO` constructor on the other hand is not an stream object but
+    an iterator::
+
+        def foo(stream):
+            stream.write("some")
+            stream.write("thing")
+            stream.flush()
+            stream.write("otherthing")
+        iterator = IterIO(foo)
+        print iterator.next()       # prints something
+        print iterator.next()       # prints otherthing
+        iterator.next()             # raises StopIteration

+    werkzeug.contrib.securecookie
+    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+    This module implements a cookie that is not alterable from the client
+    because it adds a checksum the server checks for.  You can use it as
+    session replacement if all you have is a user id or something to mark
+    a logged in user.
+
+    Keep in mind that the data is still readable from the client as a
+    normal cookie is.  However you don't have to store and flush the
+    sessions you have at the server.
+
+    Example usage:
+
+    >>> from werkzeug.contrib.securecookie import SecureCookie
+    >>> x = SecureCookie({"foo": 42, "baz": (1, 2, 3)}, "deadbeef")
+
+    Dumping into a string so that one can store it in a cookie:
+
+    >>> value = x.serialize()
+
+    Loading from that string again:
+
+    >>> x = SecureCookie.unserialize(value, "deadbeef")
+    >>> x["baz"]
+    (1, 2, 3)
+
+    If someone modifies the cookie and the checksum is wrong the unserialize
+    method will fail silently and return a new empty `SecureCookie` object.
+
+    Keep in mind that the values will be visible in the cookie so do not
+    store data in a cookie you don't want the user to see.
+
+    Application Integration
+    =======================
+
+    If you are using the werkzeug request objects you could integrate the
+    secure cookie into your application like this::
+
+        from werkzeug.utils import cached_property
+        from werkzeug.wrappers import BaseRequest
+        from werkzeug.contrib.securecookie import SecureCookie
+
+        # don't use this key but a different one; you could just use
+        # os.urandom(20) to get something random
+        SECRET_KEY = '\xfa\xdd\xb8z\xae\xe0}4\x8b\xea'
+
+        class Request(BaseRequest):
+
+            @cached_property
+            def client_session(self):
+                data = self.cookies.get('session_data')
+                if not data:
+                    return SecureCookie(secret_key=SECRET_KEY)
+                return SecureCookie.unserialize(data, SECRET_KEY)
+
+        def application(environ, start_response):
+            request = Request(environ)
+
+            # get a response object here
+            response = ...
+
+            if request.client_session.should_save:
+                session_data = request.client_session.serialize()
+                response.set_cookie('session_data', session_data,
+                                    httponly=True)
+            return response(environ, start_response)
+
+    A less verbose integration can be achieved by using shorthand methods::
+
+        class Request(BaseRequest):
+
+            @cached_property
+            def client_session(self):
+                return SecureCookie.load_cookie(self, secret_key=COOKIE_SECRET)
+
+        def application(environ, start_response):
+            request = Request(environ)
+
+            # get a response object here
+            response = ...
+
+            request.client_session.save_cookie(response)
+            return response(environ, start_response)

+    werkzeug.contrib.sessions
+    ~~~~~~~~~~~~~~~~~~~~~~~~~
+
+    This module contains some helper classes that help one to add session
+    support to a python WSGI application.  For full client-side session
+    storage see :mod:`~werkzeug.contrib.securecookie` which implements a
+    secure, client-side session storage.
+
+
+    Application Integration
+    =======================
+
+    ::
+
+        from werkzeug.contrib.sessions import SessionMiddleware, \
+             FilesystemSessionStore
+
+        app = SessionMiddleware(app, FilesystemSessionStore())
+
+    The current session will then appear in the WSGI environment as
+    `werkzeug.session`.  However it's recommended to not use the middleware
+    but the stores directly in the application.  However for very simple
+    scripts a middleware for sessions could be sufficient.
+
+    This module does not implement methods or ways to check if a session is
+    expired.  That should be done by a cronjob and storage specific.  For
+    example to prune unused filesystem sessions one could check the modified
+    time of the files.  If sessions are stored in the database the new()
+    method should add an expiration timestamp for the session.
+
+    For better flexibility it's recommended to not use the middleware but the
+    store and session object directly in the application dispatching::
+
+        session_store = FilesystemSessionStore()
+
+        def application(environ, start_response):
+            request = Request(environ)
+            sid = request.cookies.get('cookie_name')
+            if sid is None:
+                request.session = session_store.new()
+            else:
+                request.session = session_store.get(sid)
+            response = get_the_response_object(request)
+            if request.session.should_save:
+                session_store.save(request.session)
+                response.set_cookie('cookie_name', request.session.sid)
+            return response(environ, start_response)

+-------------------------------
+UBUNTU FONT LICENCE Version 1.0
+-------------------------------
+
+PREAMBLE
+This licence allows the licensed fonts to be used, studied, modified and
+redistributed freely. The fonts, including any derivative works, can be
+bundled, embedded, and redistributed provided the terms of this licence
+are met. The fonts and derivatives, however, cannot be released under
+any other licence. The requirement for fonts to remain under this
+licence does not require any document created using the fonts or their
+derivatives to be published under this licence, as long as the primary
+purpose of the document is not to be a vehicle for the distribution of
+the fonts.
+
+DEFINITIONS
+"Font Software" refers to the set of files released by the Copyright
+Holder(s) under this licence and clearly marked as such. This may
+include source files, build scripts and documentation.
+
+"Original Version" refers to the collection of Font Software components
+as received under this licence.
+
+"Modified Version" refers to any derivative made by adding to, deleting,
+or substituting -- in part or in whole -- any of the components of the
+Original Version, by changing formats or by porting the Font Software to
+a new environment.
+
+"Copyright Holder(s)" refers to all individuals and companies who have a
+copyright ownership of the Font Software.
+
+"Substantially Changed" refers to Modified Versions which can be easily
+identified as dissimilar to the Font Software by users of the Font
+Software comparing the Original Version with the Modified Version.
+
+To "Propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy. Propagation includes copying,
+distribution (with or without modification and with or without charging
+a redistribution fee), making available to the public, and in some
+countries other activities as well.
+
+PERMISSION & CONDITIONS
+This licence does not grant any rights under trademark law and all such
+rights are reserved.
+
+Permission is hereby granted, free of charge, to any person obtaining a
+copy of the Font Software, to propagate the Font Software, subject to
+the below conditions:
+
+1) Each copy of the Font Software must contain the above copyright
+notice and this licence. These can be included either as stand-alone
+text files, human-readable headers or in the appropriate machine-
+readable metadata fields within text or binary files as long as those
+fields can be easily viewed by the user.
+
+2) The font name complies with the following:
+(a) The Original Version must retain its name, unmodified.
+(b) Modified Versions which are Substantially Changed must be renamed to
+avoid use of the name of the Original Version or similar names entirely.
+(c) Modified Versions which are not Substantially Changed must be
+renamed to both (i) retain the name of the Original Version and (ii) add
+additional naming elements to distinguish the Modified Version from the
+Original Version. The name of such Modified Versions must be the name of
+the Original Version, with "derivative X" where X represents the name of
+the new work, appended to that name.
+
+3) The name(s) of the Copyright Holder(s) and any contributor to the
+Font Software shall not be used to promote, endorse or advertise any
+Modified Version, except (i) as required by this licence, (ii) to
+acknowledge the contribution(s) of the Copyright Holder(s) or (iii) with
+their explicit written permission.
+
+4) The Font Software, modified or unmodified, in part or in whole, must
+be distributed entirely under this licence, and must not be distributed
+under any other licence. The requirement for fonts to remain under this
+licence does not affect any document created using the Font Software,
+except any version of the Font Software extracted from a document
+created using the Font Software may only be distributed under this
+licence.
+
+TERMINATION
+This licence becomes null and void if any of the above conditions are
+not met.
+
+DISCLAIMER
+THE FONT SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND,

+    werkzeug.exceptions
+    ~~~~~~~~~~~~~~~~~~~
+
+    This module implements a number of Python exceptions you can raise from
+    within your views to trigger a standard non-200 response.
+
+
+    Usage Example
+    -------------
+
+    ::
+
+        from werkzeug.wrappers import BaseRequest
+        from werkzeug.wsgi import responder
+        from werkzeug.exceptions import HTTPException, NotFound
+
+        def view(request):
+            raise NotFound()
+
+        @responder
+        def application(environ, start_response):
+            request = BaseRequest(environ)
+            try:
+                return view(request)
+            except HTTPException as e:
+                return e
+
+
+    As you can see from this example those exceptions are callable WSGI
+    applications.  Because of Python 2.4 compatibility those do not extend
+    from the response objects but only from the python exception class.
+
+    As a matter of fact they are not Werkzeug response objects.  However you
+    can get a response object by calling ``get_response()`` on a HTTP
+    exception.
+
+    Keep in mind that you have to pass an environment to ``get_response()``
+    because some errors fetch additional information from the WSGI
+    environment.
+
+    If you want to hook in a different exception page to say, a 404 status
+    code, you can add a second except for a specific subclass of an error::
+
+        @responder
+        def application(environ, start_response):
+            request = BaseRequest(environ)
+            try:
+                return view(request)
+            except NotFound, e:
+                return not_found(request)
+            except HTTPException, e:
+                return e

+Application Dispatcher
+======================
+
+This middleware creates a single WSGI application that dispatches to
+multiple other WSGI applications mounted at different URL paths.
+
+A common example is writing a Single Page Application, where you have a
+backend API and a frontend written in JavaScript that does the routing
+in the browser rather than requesting different pages from the server.
+The frontend is a single HTML and JS file that should be served for any
+path besides "/api".
+
+This example dispatches to an API app under "/api", an admin app
+under "/admin", and an app that serves frontend files for all other
+requests::
+
+    app = DispatcherMiddleware(serve_frontend, {
+        '/api': api_app,
+        '/admin': admin_app,
+    })
+
+In production, you might instead handle this at the HTTP server level,
+serving files or proxying to application servers based on location. The
+API and admin apps would each be deployed with a separate WSGI server,
+and the static files would be served directly by the HTTP server.

+    Each host has the following options:
+
+    ``target``:
+        The target URL to dispatch to. This is required.
+    ``remove_prefix``:
+        Whether to remove the prefix from the URL before dispatching it
+        to the target. The default is ``False``.
+    ``host``:
+        ``"<auto>"`` (default):
+            The host header is automatically rewritten to the URL of the
+            target.
+        ``None``:
+            The host header is unmodified from the client request.
+        Any other value:
+            The host header is overwritten with the value.
+    ``headers``:
+        A dictionary of headers to be sent with the request to the
+        target. The default is ``{}``.
+    ``ssl_context``:
+        A :class:`ssl.SSLContext` defining how to verify requests if the
+        target is HTTPS. The default is ``None``.
+
+    In the example above, everything under ``"/static/"`` is proxied to
+    the server on port 5001. The host header is rewritten to the target,
+    and the ``"/static/"`` prefix is removed from the URLs.

+X-Forwarded-For Proxy Fix
+=========================
+
+This module provides a middleware that adjusts the WSGI environ based on
+``X-Forwarded-`` headers that proxies in front of an application may
+set.
+
+When an application is running behind a proxy server, WSGI may see the
+request as coming from that server rather than the real client. Proxies
+set various headers to track where the request actually came from.
+
+This middleware should only be applied if the application is actually
+behind such a proxy, and should be configured with the number of proxies
+that are chained in front of it. Not all proxies set all the headers.
+Since incoming headers can be faked, you must set how many proxies are
+setting each header so the middleware knows what to trust.

+    """A WSGI middleware that provides static content for development
+    environments or simple server setups. Usage is quite simple::
+
+        import os
+        from werkzeug.wsgi import SharedDataMiddleware
+
+        app = SharedDataMiddleware(app, {
+            '/static': os.path.join(os.path.dirname(__file__), 'static')
+        })
+
+    The contents of the folder ``./shared`` will now be available on
+    ``http://example.com/shared/``.  This is pretty useful during development
+    because a standalone media server is not required.  One can also mount
+    files on the root folder and still continue to use the application because
+    the shared data middleware forwards all unhandled requests to the
+    application, even if the requests are below one of the shared folders.
+
+    If `pkg_resources` is available you can also tell the middleware to serve
+    files from package data::
+
+        app = SharedDataMiddleware(app, {
+            '/static': ('myapplication', 'static')
+        })
+
+    This will then serve the ``static`` folder in the `myapplication`
+    Python package.
+
+    The optional `disallow` parameter can be a list of :func:`~fnmatch.fnmatch`
+    rules for files that are not accessible from the web.  If `cache` is set to
+    `False` no caching headers are sent.
+
+    Currently the middleware does not support non ASCII filenames.  If the
+    encoding on the file system happens to be the encoding of the URI it may
+    work but this could also be by accident.  We strongly suggest using ASCII
+    only file names for static files.
+
+    The middleware will guess the mimetype using the Python `mimetype`
+    module.  If it's unable to figure out the charset it will fall back
+    to `fallback_mimetype`.
+
+    .. versionchanged:: 0.5
+       The cache timeout is configurable now.

+                application you can pass it :exc:`NotFound`.

+
+    Provides a POSIX emulation for some features that are relevant to
+    web applications.  The main purpose is to simplify support for
+    systems such as Windows NT that are not 100% POSIX compatible.
+
+    Currently this only implements a :func:`rename` function that
+    follows POSIX semantics.  Eg: if the target file already exists it
+    will be replaced without asking.
+
+    This module was introduced in 0.6.1 and is not a public interface.
+    It might become one in later versions of Werkzeug.

+werkzeug.wrappers
+~~~~~~~~~~~~~~~~~
+
+The wrappers are simple request and response objects which you can
+subclass to do whatever you want them to do.  The request object contains
+the information transmitted by the client (webbrowser) and the response
+object contains all the information sent back to the browser.
+
+An important detail is that the request object is created with the WSGI
+environ and will act as high-level proxy whereas the response object is an
+actual WSGI application.
+
+Like everything else in Werkzeug these objects will work correctly with
+unicode data.  Incoming form data parsed by the response object will be
+decoded into an unicode object if possible and if it makes sense.
