This LaTeX template contains the rough structure of my book, A Programmer's Introduction to Mathematics.

Compile with latexmk book.tex using the following .latexmkrc

$pdf_mode = 1;
$postscript_mode = 0;
$dvi_mode = 0;
$pdflatex = 'xelatex -interaction=nonstopmode';
$pdf_previewer = "open -a /Applications/Skim.app";
$clean_ext = "paux lox pdfsync out";

book.tex is the main entry point that includes the book templating files, front/end matter, and the individual sources from each chapter. When creating a new chapter, add a new file to chapters and add it to the includeonly and input sections of book.tex.

structure.tex contains the main work of setting up formatting and style, including margins and page size, code listings, theorem environments, etc.

The remaining files should be self-explanatory.
