>I now have 10+ conditional flags in my book: ifPG13, ifPRINT, ifEBOOK, ifEREADER, etc. I'm looking to add more, but the basic \ifthenelse macro in LaTeX won't be enough... Makefiles can be your friend... in the file `Makefile` put .PHONY: all pg13 print ebook ereader all: pg13 print ebook ereader pg13: book-pg13.pdf book-pg13.pdf: mainfile.tex pdflatex "\setstuffforethisversion\input{mainfile}" print: book-print.pdf [etc...] Then type `make print` or `make ebook` etc at the command line. (This version is almost certainly too simplistic, but I hope the point is clear.)

Hm... reading-in the src from the command looks a little brittle, but it's a must try. The makefile will also help with the need to compile 3 times with latex.

  It's definitely brittle, but it's brittle along a dimension that usually doesn't change much over the course of the project (paper, book, etc). If you have automatically generated images or tables the benefits can be huge. `latexmk` solves the "compile many times" problem, and can monitor for changes to the source file in the background.
