	The way I did it was to redefine the LaTeX \chapter command
	to execute a user-defined "hook" at the right place for each
	new chapter (i.e., after the double page has been flushed, but 
	before the title is set), as shown in this fragment from
	my style file (which modifies the "book" style):


%%%%%%%%%%%%%%%% begin "mybook.sty" %%%%%%%%%%%%%%%%

\input book.sty
		% add "\everychapter" hook for use at every \chapter command
\def\everychapter#1{\gdef\@everychapter{#1}}
\def\@everychapter{}
		% redefine the \chapter command to include the "hook"
\def\chapter{\cleardoublepage \thispagestyle{plain} \global\@topnum\z@
 \@afterindentfalse \@everychapter \secdef\@chapter\@schapter} 

%%%%%%%%%%%%%%%% end "mybook.sty" %%%%%%%%%%%%%%%%


	Then I can use that hook to automatically reset the page counter 
	at the beginning of every chapter.  In the following example,
	note that the preface section uses lower cases roman numerals
	for page numbers (as set by the first "\renewcommand"), while 
	the main body uses chapter--page numbers (as set by the second
	"\renewcommand"):


%%%%%%%%%%%%%%%% begin "thebook.tex" %%%%%%%%%%%%%%%%

\documentstyle{mybook}

\begin{document}

		% preface section - roman numeral page nums
\renewcommand{\thepage}{\roman{page}}
\include{titlepage}

\include{contents}

\include{preface}

		% main body - number pages within chapters
\renewcommand{\thepage}{\thechapter--\arabic{page}}
\everychapter{\setcounter{page}{1}}

\include{introduction} 	% ch1

\include{structural} 	% ch2

\include{surveying} 	% ch3

%% ... etc.

%%%%%%%%%%%%%%%% end "thebook.tex" %%%%%%%%%%%%%%%%


	The "\include"ed files simply start the "\chapter"
	commands -- there is nothing special in them.  And the
	table of contents is correct, automatically.

	By the way, I have a modified version of an old version of an index
	sort/merge program distributed by the Free Software Foundation
	that works with page numbers of this type.  Source
	available, of course.
