# High-level directory definitions
# --------------------------------
#
# Basic directories that are used throughout the project.
#
# Locks are used to make sure that an operation is done in series not in
# parallel (even if Make is run in parallel with the `-j' option). The most
# common case is downloads which are better done in series and not in
# parallel. Also, some programs may not be thread-safe, therefore it will
# be necessary to put a lock on them. This project uses the `flock' program
# to achieve this.

# Preparation phase
# -----------------
#
# This Makefile is loaded both for the `prepare' phase and the `make'
# phase. But the preparation files should be dealt with differently
# (depending on the phase). In the `prepare' phase, the main directory
# should be created, and in the `make' phase, its contents should be
# loaded.
#
# If you don't need any preparation, please simply comment these lines.

# TeX build directory
# ------------------
#
# In scenarios where multiple users are working on the project
# simultaneously, they can't all build the final paper together, there will
# be conflicts! It is possible to manage the working on the analysis, so no
# conflict is caused in that phase, but it would be very slow to only let
# one of the project members to build the paper at every instance
# (independent parts of the paper can be added to it independently). To fix
# this problem, when we are in a group setting, we'll use the user's ID to
# create a separate LaTeX build directory for each user.
#
# The same logic applies to the final paper PDF: each user will create a
# separte final PDF (for example `paper-user1.pdf' and `paper-user2.pdf')
# and no `paper.pdf' will be built. This isn't a problem because
# `initialize.tex' is a .PHONY prerequisite, so the rule to build the final
# paper is always executed (even if it is present and nothing has
# changed). So in terms of over-all efficiency and processing steps, this
# doesn't change anything.

# High level environment
# ----------------------
#
# We want the full recipe to be executed in one call to the shell. Also we
# want Make to run the specific version of Bash that we have installed
# during `./project configure' time.
#
# Regarding the directories, this project builds its major dependencies
# itself and doesn't use the local system's default tools. With these
# environment variables, we are setting it to prefer the software we have
# build here.
#
# `TEXINPUTS': we have to remove all possible user-specified directories to
# avoid conflicts with existing TeX Live solutions. Later (in `paper.mk'),
# we are also going to overwrite `TEXINPUTS' just before `pdflatex'.

# The `.SUFFIXES' rule with no prerequisite is defined to eliminate all the

# option: they add too many extra checks that make it hard to find what you

# the project version which may change between two separate runs, even when
