5.8 @subsection: Subsections Below Sections

Subsections are to sections as sections are to chapters; see @section. In Info and plain text, subsection titles are underlined with ‘-’. For example,

@subsection This is a subsection

might produce

1.2.3 This is a subsection
--------------------------

Subsection titles are listed in the table of contents.

The TeX, HTML, Docbook, and XML output is all analogous to the chapter-level output, just “two levels down”; see @chapter.
