# LaTeX macros for paper
# ----------------------
#
# To report the input settings and results, the final report's PDF (final
# target of this project) uses macros generated from various steps of the
# project. All these macros are defined through `$(mtexdir)/project.tex'.
#
# `$(mtexdir)/project.tex' is actually just a combination of separate files
# that keep the LaTeX macros related to each workhorse Makefile (in
# `reproduce/src/make/*.mk'). Those individual macros are pre-requisites to
# `$(mtexdir)/verify.tex' which will check them before starting to build
# the paper. The only workhorse Makefile that doesn't need to produce LaTeX
# macros is this Makefile (`reproduce/src/make/paper.mk').
#
# This file is thus the interface between the analysis/processing steps and
# the final PDF: when we get to this point, all the processing has been
# completed.
#
# Note that if you don't want the final PDF and just want the processing
# and file outputs, you can remove the value of `pdf-build-final' in
# `reproduce/analysis/config/pdf-build.conf'.
$(mtexdir)/project.tex: $(mtexdir)/verify.tex
# If no PDF is requested, or if LaTeX isn't available, don't
# continue to building the final PDF. Otherwise, merge all the TeX
# macros into one for building the PDF.
@if [ -f .local/bin/pdflatex ] && [ x"$(pdf-build-final)" != x ]; then
# Put a LaTeX input command for all the necessary macro files.

# The bibliography
# ----------------
#
# We need to run the `biber' program on the output of LaTeX to generate the
# necessary bibliography before making the final paper. So we'll first have
# one run of LaTeX (similar to the `paper.pdf' recipe), then `biber'.
#
# NOTE: `$(mtexdir)/project.tex' is an order-only-prerequisite for
# `paper.bbl'. This is because we need to run LaTeX in both the `paper.bbl'
# recipe and the `paper.pdf' recipe. But if `tex/src/references.tex' hasn't
# been modified, we don't want to re-build the bibliography, only the final
# PDF.
