Generate mode builds the _dmarc TXT record from the fields — policy and subdomain policy, aggregate (rua) and failure (ruf) report addresses, alignment modes, percentage, failure options and report interval — and prints the DNS name, value, a zone-file line, what each tag means, and the authorization record any external report destination must publish. Analyze mode parses a pasted record, validates every tag against RFC 7489 and flags weak settings (p=none, no rua, pct below 100, sp=none). No DNS lookups are made.
