+    WSGI Handler form Mod Python:
+    
+    This module implement cgihandler-like functionality but for WSGI.
+    It allows to call standalone WSGI script without too much configuration,
+    and keep serving static files in the same directory (ala PHP)
+
+    Each script (.py) must contain a WSGI compilant callable named WSGIApp
+
+    Use .htaccess:
+        AddHandler mod_python .py
+        PythonHandler wsgihandler
+
+    This need either modpywsgi.py or modpython_gateway.py (WSGI gateways) be
+    present inside python path.
+    
+    If this script is stored inside python path (normally site-packages),
+    no PythonPath directive is needed (script directory is appended to
+    sys.path), so you could import modules in script directory normally. 
+    
+    If you cannot install both scripts in site-packages, just modify .htaccess:
+        AddHandler mod_python .py
+        PythonHandler wsgihandler
+        PythonPath "['/your/script/path'] + sys.path"
+    And copy modpywsgi.py or modpython_gateway.py and wsgihandler.py with your
+    script.
