Rhino python script

I want to spawn Rhino application from batch file and pass Rhino python script as argument, so that it can execute as soon as Rhino starts.
Please let me know, how to go about.
Earlier I was able to do same for Rhino command script by “Rhino.exe MyRhinoCommandScript.txt” in the batch file.
