[#font-style]
=== font-style

The dot leader inherits all font properties except `font-style` from the parent `toc` category.

[#dot-levels]
=== levels

The integers assigned to the `levels` key are based on the AsciiDoc section levels.
That is part = 0, chapter = 1, etc.
Dot leaders are only shown for the specified levels.
If a value isn't specified, dot leaders are shown for all levels.
