+#
+# To use this class, users must do the following:
+# 1. Download and install the PyWin32all package
+#    (http://starship.python.net/crew/mhammond/win32/)
+# 2. Edit the constants section with the proper information.
+# 3. Open a command prompt with administrator rights and navigate to the directory
+#    where this file is located.  Use one of the following commands to
+#    install/start/stop/remove the service:
+#    > memcached_service.py install
+#    > memcached_service.py start
+#    > memcached_service.py stop
+#    > memcached_service.py remove
+#    Additionally, typing "memcached_service.py" will present the user with all of the
+#    available options.
+#
+# Once installed, the service will be accessible through the Services
+# management console just like any other Windows Service.  All service 
+# startup exceptions encountered by the MemcachedWindowsService class will be 
+# viewable in the Windows event viewer (this is useful for debugging
+# service startup errors); all application specific output or exceptions that
+# are not captured by the standard memcached logging mechanism should 
+# appear in the stdout/stderr logs.
