seppdflatex
Build a large LaTeX book with separate linked chapters
...The Table of Contents and LOF and LOT are made for all chapters, and the TOC, LOF, LOT are all hyperlinked to the correct external PDF chapter files using zr-ref and xr packages from CTAN. But you have to write the correct LaTeX source. The script seppdflatex does the compilation and formatting of Table of Contents and such-like and separates out the chapters as standalone PDF files. The script uses the free software pdftk and pdfsam-console, as well as a bunch of handy CPAN modules, which you will need to install first.
