How do I format a book so that the chapters are sub-divided into numbered sections, where:
only the section number, but not the chapter number, appears in the section heading (i.e. the third section of chapter four should be headed by 3, rather than by 4.3);
the section number is centered in the page; and
the section number is preceded by a "section" symbol?
And is there a command that will produce the section numbers in lowercase roman numerals?
