- How deep it goes
- Explains stream selection, variadic correspondence, format components, conversions, and modifiers, but defers complete conversion tables to reference tables.
- Examples
- Uses `stderr` diagnostics, numeric conversions, and conditional tracing macros that forward literal formats and values.
- What you can do after
- Apply it via the C standard library to direct correctly formatted values to a selected stream and build checked tracing macros.
