report-cacher -interval=6h -site='https://jonesboroughfarmersmkt.shopkeepapp.com' \
-email='user@domain.com' -password='mypassword' -directory='cache' -port=8080

The above commands result in the reports being downloaded every 6 hours from the time the script starts until it is stopped. They are downloaded to the cache directory and served from a web server on port 8080. They can be accessed at http://localhost:8080/. The email and password are to an account that has access to https://jonesboroughfarmersmkt.shopkeepapp.com.

Passing -noweb instead of -port=8080 will result in the webserver being disabled. Thus, the files will only be accessible to applications on the local machine that have permission to read files in the cache directory.
