-Middleware to check for obedience to the WSGI specification.
-
-Some of the things this checks:
-
-* Signature of the application and start_response (including that
-  keyword arguments are not used).
-
-* Environment checks:
-
-  - Environment is a dictionary (and not a subclass).
-
-  - That all the required keys are in the environment: REQUEST_METHOD,
-    SERVER_NAME, SERVER_PORT, wsgi.version, wsgi.input, wsgi.errors,
-    wsgi.multithread, wsgi.multiprocess, wsgi.run_once
-
-  - That HTTP_CONTENT_TYPE and HTTP_CONTENT_LENGTH are not in the
-    environment (these headers should appear as CONTENT_LENGTH and
-    CONTENT_TYPE).
-
-  - Warns if QUERY_STRING is missing, as the cgi module acts
-    unpredictably in that case.
-
-  - That CGI-style variables (that don't contain a .) have
-    (non-unicode) string values
-
-  - That wsgi.version is a tuple
-
-  - That wsgi.url_scheme is 'http' or 'https' (@@: is this too
-    restrictive?)
-
-  - Warns if the REQUEST_METHOD is not known (@@: probably too
-    restrictive).
-
-  - That SCRIPT_NAME and PATH_INFO are empty or start with /
-
-  - That at least one of SCRIPT_NAME or PATH_INFO are set.
-
-  - That CONTENT_LENGTH is a positive integer.
-
-  - That SCRIPT_NAME is not '/' (it should be '', and PATH_INFO should
-    be '/').
-
-  - That wsgi.input has the methods read, readline, readlines, and
-    __iter__
-
-  - That wsgi.errors has the methods flush, write, writelines
-
-* The status is a string, contains a space, starts with an integer,
-  and that integer is in range (> 100).
-
-* That the headers is a list (not a subclass, not another kind of
-  sequence).
-
-* That the items of the headers are tuples of strings.
-
-* That there is no 'status' header (that is used in CGI, but not in
-  WSGI).
-
-* That the headers don't contain newlines or colons, end in _ or -, or
-  contain characters codes below 037.
-
-* That Content-Type is given if there is content (CGI often has a
-  default content type, but WSGI does not).
-
-* That no Content-Type is given when there is no content (@@: is this
-  too restrictive?)
-
-* That the exc_info argument to start_response is a tuple or None.
-
-* That all calls to the writer are with strings, and no other methods
-  on the writer are accessed.
-
-* That wsgi.input is used properly:
-
-  - .read() is called with zero or one argument
-
-  - That it returns a string
-
-  - That readline, readlines, and __iter__ return strings
-
-  - That .close() is not called
-
-  - No other methods are provided
-
-* That wsgi.errors is used properly:
-
-  - .write() and .writelines() is called with a string
-
-  - That .close() is not called, and no other methods are provided.
-
-* The response iterator:
-
-  - That it is not a string (it should be a list of a single string; a
-    string will work, but perform horribly).
-
-  - That .next() returns a string
-
-  - That the iterator is not iterated over until start_response has
-    been called (that can signal either a server or application
-    error).
-
-  - That .close() is called (doesn't raise exception, only prints to
-    sys.stderr, because we only know it isn't called when the object
-    is garbage collected).
