+# Script to get all of the destinations we could show on a given Screen
+# Uses the local.json file to find each relevant screen's departure query params,
+# then makes API calls to find the unique headsigns for those queries,

+# Example usage:
+# To run with no special filters and output to the default file:
+#   `elixir scripts/screen_destinations.exs`
+# To narrow the scope to a set of screens and specify an output file:
+#   `elixir scripts/screen_destinations.exs --screens=PRE-159,PRE-160 --file=filtered_screen_destinations.csv`
