    <para>When greater than 0, the preface headings appear in the TOC. The

parameter value define the preface section depth appearing in the TOC and in

the bookmarks. If set to 0, none of the sections are put in the TOC. If set to

1, only the chapter level appears in the TOC and bookmarks, and so on. When

the parameter is negative, it behaves like with 0, but it uses the previous

implementation (use of unnumbered sections, that is, with latex heading

commands ending with '*').</para>
