`@majorheading', `@chapheading'
===============================
The `@majorheading' and `@chapheading' commands put chapter-like
headings in the body of a document.
However, neither command causes TeX to produce a numbered heading or
an entry in the table of contents; and neither command causes TeX to
start a new page in a printed manual.
In TeX, an `@majorheading' command generates a larger vertical
whitespace before the heading than an `@chapheading' command but is
otherwise the same.
In Info, the `@majorheading' and `@chapheading' commands are
equivalent to `@chapter': the title is printed on a line by itself with
a line of asterisks underneath. (Note:`@chapter'.)
