+"""BaseHTTPServer that implements the Python WSGI protocol (PEP 3333)
+
+This is both an example of how WSGI can be implemented, and a basis for running
+simple web applications on a local machine, such as might be done when testing
+or debugging an application.  It has not been reviewed for security issues,
+however, and we strongly recommend that you use a "real" web server for
+production use.
+
+For example usage, see the 'if __name__=="__main__"' block at the end of the
+module.  See also the BaseHTTPServer module docs for other API information.
