+       This command initializes the package for persistence and used in one time generation of the clients.
+       This command will create a new directory named 'persist' in the project directory. The 'persist' directory will
+       contain empty model definition file which can be used to define the data model of the Ballerina project.

+       $ bal persist generate --module persist --datastore mysql
