 ## `listy sync`
 
 Besides the Go server (run with `listy server run`) the `sync` command provides most of the functionality in a self-contained worker that can either be run once or repeated by providing the `--repeat` flag which will be parsed by Go's [`time.ParseDuration()`](https://pkg.go.dev/time#ParseDuration) function. This will allow the sync script to run indefinitely.
