+This is a C# program that takes command line arguments and generates various reports based on the options passed. It uses the CommandLine library to parse the arguments and then maps the options to corresponding reporting classes. The program also logs events using the NLog library, and exceptions are caught and logged as warnings with their corresponding messages. The SanitizeOptions function is used to sanitize input options based on their types.
