Conventions used on these pages

• Flags written --name are long form. When a short form exists, it is shown next to the long form.
• PATH, QUERY, LEVEL, and so on are placeholders for the value the flag expects.
• Code blocks use $ to mark interactive shell prompts. Output lines have no prompt.
• Exit codes are documented on concepts/exit-codes; command pages link to the codes they can emit.
