Short: "export vulnerability data from the database",

The export command returns data from all vendors + overrides.
The --format flag is required and must be one of csv or nvdcvejson.
The --provider flag is optional, as well as the list of IDs to filter in.
Use the JSON_INDENT environment variable to set the indentation character
for JSON output, e.g. JSON_INDENT=$'\t' or use jq.
