+NSSM: The Non-Sucking Service Manager
+Version 1.0, 2003-05-30
+
+NSSM is a service helper program similar to srvany and cygrunsrv.  It can 
+start any application as an NT service and will restart the service if it 
+fails for any reason.
+
+NSSM also has a graphical service installer and remover.
+
+
+Installation
+------------
+To install a service, run
+
+    nssm install servicename
+
+You will be prompted to enter the full path to the application you wish 
+to run and any commandline options to pass to that application.
+
+Use the system service manager (services.msc) to control advanced service 
+properties such as startup method and desktop interaction.  NSSM may 
+support these options at a later time...
+
+
+Managing the service
+--------------------
+NSSM will launch the application listed in the registry when you send it a 
+start signal and will terminate it when you send a stop signal.  So far, so 
+much like srvany.  But NSSM is the Non-Sucking service manager and will take 
+action if/when the application dies.
+
+NSSM will try to restart itself if it notices that the application died but 
+you didn't send it a stop signal.  NSSM will keep trying, pausing 30 seconds 
+between each attempt, until the service is successfully started or you send 
+it a stop signal.
+
+
+Removing services
+-----------------
+NSSM can also remove services.  Run
+
+    nssm remove servicename
+
+to remove a service.  You will prompted for confirmation before the service 
+is removed.  Try not to remove essential system services...
+
+
+Licence
+-------
+NSSM is public domain.  You may unconditionally use it and/or its source code 
+for any purpose you wish.
