6.5. Chapter headingsThe command \chapterprecis prints its argument both at the point in the documentwhere it is called, and also adds it to the .toc file. For example:...\chapter{}% first chapter\chapterprecis{Our hero is introduced; family tree; early days.}...Now for the details.\prechapterprecisshiftThe length \prechapterprecisshift controls the vertical spacing before a\chapterprecis. If the precis immediately follows a \chapter then a different space isrequired depending on whether or not the article class option is used. The class sets:\ifartopt\setlength{\prechapterprecisshift}{0pt}\else\setlength{\prechapterprecisshift}{-2\baselineskip}\fi\chapterprecishere{〈text〉}\chapterprecistoc{〈text〉}The \chapterprecis command calls these two commands to print the 〈text〉 inthe document (the \chapterprecishere command) and to put it into the ToC (the\chapterprecistoc command). These can be used individually if required.\precisfont\prechapterprecis \postchapterprecisThe \chapterprecishere macro is intended for use immediately after a \chapter. The〈text〉 argument is typeset in the \precisfont font in a quote environment. The macro’sdefinition is:\newcommand{\chapterprecishere}[1]{%\prechapterprecis #1\postchapterprecis}where \prechapterprecis, \postchapterprecis and \precisfont are defined as:\newcommand{\prechapterprecis}{%\vspace*{\prechapterprecisshift}%\begin{quote}\precisfont}\newcommand{\postchapterprecis}{\end{quote}}\newcommand*{\precisfont}{\normalfont\itshape}Any or all of these can be changed if another style of typesetting is required.Next the following macros control the formatting of the precis text in the ToC.\precistoctext{〈text〉} \precistocfont \precistocformatThe \chapterprecistoc macro puts \precistoctext{〈text〉} into the toc file.
