+Werkzeug
+========
+
+Werkzeug is a comprehensive `WSGI`_ web application library. It began as
+a simple collection of various utilities for WSGI applications and has
+become one of the most advanced WSGI utility libraries.
+
+It includes:
+
+* An interactive debugger that allows inspecting stack traces and source
+  code in the browser with an interactive interpreter for any frame in
+  the stack.
+* A full-featured request object with objects to interact with headers,
+  query args, form data, files, and cookies.
+* A response object that can wrap other WSGI applications and handle
+  streaming data.
+* A routing system for matching URLs to endpoints and generating URLs
+  for endpoints, with an extensible system for capturing variables from
+  URLs.
+* HTTP utilities to handle entity tags, cache control, dates, user
+  agents, cookies, files, and more.
+* A threaded WSGI server for use while developing applications locally.
+* A test client for simulating HTTP requests during testing without
+  requiring running a server.
+
+Werkzeug is Unicode aware and doesn't enforce any dependencies. It is up
+to the developer to choose a template engine, database adapter, and even
+how to handle requests. It can be used to build all sorts of end user
+applications such as blogs, wikis, or bulletin boards.
+
+`Flask`_ wraps Werkzeug, using it to handle the details of WSGI while
+providing more structure and patterns for defining powerful
+applications.
