+"""Extract data on near-Earth objects and close approaches from CSV and JSON files.

+The `load_neos` function extracts NEO data from a CSV file, formatted as
+described in the project instructions, into a collection of `NearEarthObject`s.
+
+The `load_approaches` function extracts close approach data from a JSON file,
+formatted as described in the project instructions, into a collection of
+`CloseApproach` objects.
+
+The main module calls these functions with the arguments provided at the command
+line, and uses the resulting collections to build an `NEODatabase`.
