+This script is used to generate _meta.js file for microservice deployment for this project.
+
+We will use nginx to route traffic to different microservices. 
+Each microservice will have its own _meta.js file, run prebuild.sh to replace _meta.js 
+before building the microservice.
+
+This script should run when you add a new microservice (add course for your note)
