      werkzeug
      ~~~~~~~~
  
      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.

  # This import magic raises concerns quite often which is why the implementation
  # and motivation is explained here in detail now.
  #
  # The majority of the functions and classes provided by Werkzeug work on the
  # HTTP and WSGI layer.  There is no useful grouping for those which is why
  # they are all importable from "werkzeug" instead of the modules where they are
  # implemented.  The downside of that is, that now everything would be loaded at
  # once, even if unused.
  #
  # The implementation of a lazy-loading module in this file replaces the
  # werkzeug package when imported from within.  Attribute access to the werkzeug
  # module will then lazily import from the modules that implement the objects.
  
  
  # import mapping to objects in other modules
