-# KNOWN ISSUES:
-# * The following occurs:

-# Compile
-# change to: \usepackage{apalike}\bibliographystyle{apalike}
-# Compile again -- BARF!
-#
-# The workaround: make clean-nographics; make
-#
-# Note that we may not be able to fix this. LaTeX itself barfs
-# on this, not the makefile. The very first invocation of LaTeX
-# (when something like this has happened) reads the existing .aux
-# file and discovers invalid commands like \citeauthoryear that
-# are only valid in the package that was just removed. It then
-# tries to parse them and explodes. It's not at all clear to me
-# how to fix this. I tried removing the .aux files on the first
-# run of LaTeX, but that necessarily requires more subsequent
-# rebuilds on common edits. There does not appear to be a
-# graceful solution to this issue.

-# * Work on issue 76: bad backtick escape for some sed versions, failure
-# to clear out the hold buffer when outputting MISSING comment.
-# - Backed out 2>&1 to &> (doesn't work in sh)
-# - Backed out using . to source variables
-# Chris Monson (2010-03-22):
-# * Bumped version to 2.2.0-beta7
-# * Issue 72: Fix latex/bibtex invocation order for annotated bib styles
-# * Fixed informational output to reflect which LaTeX run we're on
-# * Fixed graphic detection to include graphics that are already there in
-# .d files
-# * Tightened up the .d file output to only make .d depend on graphic
-# *source* files. This means that building foo.d no longer
-# builds all of the graphics files on which foo.tex depends.
-# Had to use .SECONDEXPANSION trickery to make it work.
-# * Changed get-graphics to only accept a stem.
-# * Fixed build-once logic for scripted .tex to work better
-# * Made get-inputs sed script more maintainable.
-# * Moved Makefile.ini import up higher.
-# * Changed bare stems to not recursively invoke make
-# * Updated diff output to be more silent everywhere
-# * Added a MISSING comment to the .d file if stuff isn't found - forces
-# removal of .1st.make file, which often forces it to try again.
-# * Fixed broken graphics-target function
-# * Added sleep to .d file generation when stuff is missing - if it
-# builds too fast, make doesn't realize it needs to be reloaded,
-# and thus never discovers some deeper dependencies (especially
-# evident when graphics are included from scripted include
-# files).
-# Chris Monson (2010-03-17):
-# * Bumped version to 2.2.0-beta6
-# * Fixed bareword builds to actually work (requires static patterns)
-# * Fixed colorization to work with new paragraph stuff
-# Chris Monson (2010-03-17):
-# * Bumped version to 2.2.0-beta5
-# * Fixed graphic detection to be much more focused - splits log file
-# into paragraphs before doing pattern matching.
-# * Fixed make foo to work properly (recursively calls make foo.pdf)
-# * Fixed gpi -> pdf generation to not waste time building .eps *after*
-# the pdf already exists.
-# * Changed log copies to include MAKE_RESTARTS as part of the name.
-# * Fixed missing include file detection (also makes use of the paragraph
-# stuff) to detect missing scripted include files.
-# Chris Monson (2010-03-16):
-# * Bumped version to 2.2.0-beta4
-# * issue 70: .pdf not moved out of the way properly on first
-# compilation, resulting in early error detection failure.
-# * issue 74: fixed broken error on missing .aux files: the
-# implementation was masking real errors.
-# Chris Monson (2010-03-15):
-# * Bumped version to 2.2.0-beta3
-# * issue 71: Made the tput dependency optional
-# * issue 73: Made .tex targets not pull in .d files (building them from
-# scripts should not require a .d)
-# * issue 74: Output a much saner error when a .aux file is not produced
-# (e.g., when you are typing "make" without arguments in a
-# directory with included .tex files that are not named with
-# ._include_.)
-# Chris Monson (2010-03-11):
-# * Bumped version to 2.2.0-beta2
-# * Fixed clean-graphics to get rid of intermediate .eps files that may
-# be hanging around
-# * Added an automatic setting to use eps terminals in pdflatex mode for
-# gnuplot if it doesn't understand pdf.
-# * issue 66: Removed grayscale generation via magic suffix. Grayscale
-# generation is now only available via GRAY=1
-# * issue 68: Added explicit handling of LC_ALL for locale-aware tools
-# like "sort"
-# Chris Monson (2010-03-10):
-# * Bumped version to 2.2.0-beta1
-# * Fixed success message to handle output message in different places
-# * Added name of produced file to success message
-# Chris Monson (2010-03-10):
-# * Bumped version to 2.2.0-alpha3
-# * Added meaningful error message for wrong hyperref options
-# * Added meaningful error message for incorrect graphics extensions
-# Chris Monson (2010-03-09):
-# * Bumped version to 2.2.0-alpha2
-# * Updated graphics handling (gnuplot and fig generate pdf natively)
-# * Changed xmgrace to output monochrome natively
-# Chris Monson (2010-03-09):
-# * Bumped version to 2.2.0-alpha1 - major change!
-# * Support pdflatex natively and by default (issue 6 - a long time coming)
-# * Add ability to have a single $HOME/.latex-makefile/Makefile.ini for
-# all invocations
-# * Reworked graphic inclusion detection so that extensions need not be
-# specified for either build strategy (e.g.,
-# \includegraphics{test1.eps} -> \includegrahpics{test1})
-# * Changed log format to include filenames and line numbers
-# Chris Monson (2010-02-04):
-# * Bumped version to 2.1.43
-# * All of the following are for issue 63 (thanks to mojoh81):
-# * Added documentation about fixing Makefile.ini default target
-# * Added perl and python script targets
-# * Fixed run logic to allow included .tex files to be scripted (the
-# run-again logic now detects missing .tex files, and the MV
-# command has been switched out for a command that only invokes
-# MV if the files exist)
-# * Changed scripted generation to only run once per make invocation
-# * Added dependency on expr
-# Chris Monson (2010-01-19):
-# * Bumped version to 2.1.42
-# * issue 62: Added .brf extension to cleanable files (backrefs)
-# Chris Monson (2010-01-07):
-# * Bumped version to 2.1.41
-# * issue 60: bad makeindex runs now error out on subsequent tries
-# Chris Monson (2009-12-01):
-# * Bumped version to 2.1.40
-# * issue 36: build all indices (for e.g., splitidx usage)
-# * issue 59: clean up all generated files (including indices)
-# Chris Monson (2009-11-23):
-# * Bumped version to 2.1.39
-# * issue 57: change ps2pdf invocations to just use gs directly
-# Chris Monson (2009-11-19):

-# BSD SED NOTES
-#
-# BSD SED is not very nice compared to GNU sed, but it is the most
-# commonly-invoked sed on Macs (being based on BSD), so we have to cater to
-# it or require people to install GNU sed. It seems like the GNU
-# requirement isn't too bad since this makefile is really a GNU makefile,
-# but apparently GNU sed is much less common than GNU make in general, so
-# I'm supporting it here.
-#
-# Sad experience has taught me the following about BSD sed:
-#
-# * \+ is not understood to mean \{1,\}
-# * \| is meaningless (does not branch)
-# * \n cannot be used as a substitution character
-# * ? does not mean \{0,1\}, but is literal
-# * a\ works, but only reliably for a single line if subsequent lines
-# have forward slashes in them (as is the case in postscript)
-#
-# For more info (on the Mac) you can consult
-#
-# man -M /usr/share/man re_format
-#
-# And look for the word "Obsolete" near the bottom.

-# in postscript and is not read-only like systemdict).
-#
-# For setrgbcolor, the weighted average of the triple is computed and the

-# procedure is called: .299R + .587G + .114B
-#
-# For sethsbcolor, the color is first converted to RGB, then to grayscale by
-# the new setrgbcolor operator as described above. Why is this done?
-# Because simply using the value component will tend to make pure colors
-# white, a very undesirable thing. Pure blue should not translate to white,
-# but to some level of gray. Conversion to RGB does the right thing. It's
-# messy, but it works.
-#
-# From
-# http://en.wikipedia.org/wiki/HSV_color_space#Transformation_from_HSV_to_RGB,
-# HSB = HSV (Value = Brightness), and the formula used to convert to RGB is
-# as follows:
-#
-# Hi = int(floor(6 * H)) mod 6
-# f = 6 * H - Hi
-# p = V(1-S)
-# q = V(1-fS)
-# t = V(1-(1-f)S)

-# if Hi = 1: R G B <-- q V p
-# if Hi = 2: R G B <-- p V t
-# if Hi = 3: R G B <-- p q V
-# if Hi = 4: R G B <-- t p V
-# if Hi = 5: R G B <-- V p q

-# DEPENDENCY-RELATED TARGETS.
-#
-
-# Generate all of the information needed to get dependencies
-# As a side effect, this creates a .dvi or .pdf file (depending on the build
-# strategy). We need to be sure to remove it if there are errors. Errors can
-# take several forms and all of them are found within the log file:
-# * There was a LaTeX error
-# * A needed file was not found
-# * Cross references need adjustment
-#
-# Behavior:
-# This rule is responsible for generating the following:
-# %.aux
-# %.d
-# %.aux.make
-# %.(pdf|dvi).1st.make (the .pdf or .dvi output file, moved)
-#
-# Steps:
-#
-# Run latex
-# Move .pdf or .dvi somewhere else (make no judgements about success)
-# Flatten the .aux file into another file
-# Add source dependencies
-# Add graphic dependencies
-# Add bib dependencies
-#
-# Create cookies for various suffixes that may represent files that
-# need to be read by LaTeX in order for it to function properly.
-#
-# Note that if some of the dependencies are discovered because they turn
-# up missing in the log file, we really need the .d file to be reloaded.
-# Adding a sleep command helps with this. Otherwise make is extremely
-# nondeterministic, sometimes working, sometimes not.
-#

-# Generates a number of possible output files from a LaTeX document and its
-# various dependencies. Handles .bib files, \include and \input, and .eps
-# graphics. All dependencies are handled automatically by running LaTeX over
-# the source.
-#
-# USAGE:
-#
-# make [GRAY=1] [VERBOSE=1] [SHELL_DEBUG=1] <target(s)>
-#
-# STANDARD OPTIONS:
-# GRAY:
-# Setting this variable forces all recompiled graphics to be grayscale.
-# It is useful when creating a document for printing. The default is
-# to allow colors. Note that it only changes graphics that need to be
-# rebuilt! It is usually a good idea to do a 'make clean' first.
-#
-# VERBOSE:
-# This turns off all @ prefixes for commands invoked by make. Thus,
-# you get to see all of the gory details of what is going on.
-#
-# SHELL_DEBUG:
-# This enables the -x option for sh, meaning that everything it does is
-# echoed to stderr. This is particularly useful for debugging
-# what is going on in $$(shell ...) invocations. One of my favorite
-# debugging tricks is to do this:
-#
-# make -d SHELL_DEBUG=1 VERBOSE=1 2>&1 | less
-#
-# KEEP_TEMP:
-# When set, this allows .make and other temporary files to stick around
-# long enough to do some debugging. This can be useful when trying to
-# figure out why gnuplot is not doing the right things, for example
-# (e.g., look for *head.make).
-#
-# STANDARD AUXILIARY FILES:
-#
-# Variables.ini (formerly Makefile.ini, which still works)
-#
-# This file can contain variable declarations that override various
-# aspects of the makefile. For example, one might specify
-#
-# neverclean := *.pdf *.ps
-# onlysources.tex := main.tex
-# LATEX_COLOR_WARNING := 'bold red uline'
-#
-# And this would override the neverclean setting to ensure that pdf
-# and ps files always remain behind, set the makefile to treat all
-# .tex files that are not "main.tex" as includes (and therefore not
-# default targets). It also changes the LaTeX warning output to be
-# red, bold, and underlined.
-#
-# There are numerous variables in this file that can be overridden in
-# this way. Search for '?=' to find them all.
-#
-# The Variables.ini is imported before *anything else* is done, so go
-# wild with your ideas for changes to this makefile in there. It
-# makes it easy to test them before submitting patches.
-#
-# If you're adding rules or targets, however, see Targets.ini below.
-#
-# Targets.ini
-#
-# This is included much later in the makefile, after all variables and
-# targets are defined. This is where you would put new make rules,
-# e.g.,
-#
-# generated.tex: generating_script.weird_lang depA depB
-# ./generating_script.weird_lang > $$@
-#
-# In this file, you have access to all of the variables that the
-# makefile creates, like $(onlysources.tex). While accessing those can
-# be somewhat brittle (they are implementation details and may change),
-# it is a great way to test your ideas when submitting feature requests.
-#
-# STANDARD ENVIRONMENT VARIABLES:
-#
-# LATEX_COLOR_WARNING '$(LATEX_COLOR_WARNING)'
-# LATEX_COLOR_ERROR '$(LATEX_COLOR_ERROR)'
-# LATEX_COLOR_UNDERFULL '$(LATEX_COLOR_UNDERFULL)'
-# LATEX_COLOR_OVERFULL '$(LATEX_COLOR_OVERFULL)'
-# LATEX_COLOR_PAGES '$(LATEX_COLOR_PAGES)'
-# LATEX_COLOR_BUILD '$(LATEX_COLOR_BUILD)'
-# LATEX_COLOR_GRAPHIC '$(LATEX_COLOR_GRAPHIC)'
-# LATEX_COLOR_DEP '$(LATEX_COLOR_DEP)'
-# LATEX_COLOR_SUCCESS '$(LATEX_COLOR_SUCCESS)'
-# LATEX_COLOR_FAILURE '$(LATEX_COLOR_FAILURE)'
-#
-# These may be redefined in your environment to be any of the following:
-#
-# black
-# red
-# green
-# yellow
-# blue
-# magenta
-# cyan
-# white
-#
-# Bold or underline may be used, as well, either alone or in combination
-# with colors:
-#
-# bold
-# uline
-#
-# Order is not important. You may want, for example, to specify:
-#
-# export LATEX_COLOR_SUCCESS='bold blue uline'
-#
-# in your .bashrc file. I don't know why, but you may want to.
-#
-# STANDARD TARGETS:
-#
-# all:
-# Make all possible documents in this directory. The documents are
-# determined by scanning for .tex and .tex.sh (described in more detail
-# later) and omitting any file that ends in ._include_.tex or
-# ._nobuild_.tex. The output is a set of .pdf files.
-#
-# If you wish to omit files without naming them with the special
-# underscore names, set the following near the top of the Makefile,
-# or (this is recommended) within a Makefile.ini in the same directory:
-#
-# includes.tex := file1.tex file2.tex
-#
-# This will cause the files listed to be considered as include files.
-#
-# If you have only few source files, you can set
-#
-# onlysources.tex := main.tex
-#
-# This will cause only the source files listed to be considered in
-# dependency detection. All other .tex files will be considered as
-# include files. Note that these options work for *any* source type,
-# so you could do something similar with includes.gpi, for example.
-# Note that this works for *any valid source* target. All of the
-# onlysources.* variables are commented out in the shipping version of
-# this file, so it does the right thing when they simply don't exist.
-# The comments are purely documentation. If you know, for example, that
-# file.mycoolformat is supported by this Makefile, but don't see the
-# "onlysources.mycoolformat" declared in the comments, that doesn't mean
-# you can't use it. Go ahead and set "onlysources.mycoolformat" and it
-# should do the right thing.
-#
-# show:
-# Builds and displays all documents in this directory. It uses the
-# environment-overridable value of VIEW_PDF (currently $(VIEW_PDF)) to
-# do its work.
-#
-# all-graphics:
-# Make all of the graphics in this directory.
-#
-# all-pstex (only for BUILD_STRATEGY=latex):
-# Build all fig files into pstex and pstex_t files. Gray DOES NOT WORK.
-#
-# all-gray-pstex (only for BUILD_STRATEGY=latex):
-# Build all fig files into grayscale pstex and pstex_t files.
-#
-# all-dot2tex:
-# Build all dot files into tex files.
-#
-# show-graphics:
-# Builds and displays all graphics in this directory. Uses the
-# environment-overridable value of VIEW_GRAPHICS (currently
-# $(VIEW_GRAPHICS)) to do its work.
-#
-# clean:
-# Remove ALL generated files, leaving only source intact.
-# This will *always* skip files mentioned in the "neverclean" variable,
-# either in this file or specified in Makefile.ini:
-#
-# neverclean := *.pdf *.ps
-#
-# The neverclean variable works on all "clean" targets below, as well.
-#
-# clean-graphics:
-# Remove all generated graphics files.
-#
-# clean-backups:
-# Remove all backup files: $(backup_patterns)
-# (XFig and other editors have a nasty habit of leaving them around)
-# Also removes Makefile-generated .temp files

-#
-# help:
-# This help text.
-#
-# version:
-# Version information about this LaTeX makefile.
-#
-# DEBUG TARGETS:
-#
-# _all_programs:
-# A list of the programs used by this makefile.
-#
-# _check_programs:
-# Checks your system for the needed software and reports what it finds.
-#
-# _check_gpi_files:
-# Checks the .gpi files in the current directory for common errors, such
-# as specification of the terminal or output file inside of the gpi file
-# itself.
-#
-# _dependency_graph:
-# Outputs a .dot file to stdout that represents a graph of LaTeX
-# dependencies. To see it, use the _show_dependency_graph target or
-# direct the output to a file, run dot on it, and view the output, e.g.:
-#
-# make _dependency_graph > graph.dot
-# dot -T ps -o graph.eps graph.dot
-# gv graph.eps
-#
-# _show_dependency_graph:
-# Makes viewing the graph simple: extracts, builds and displays the
-# dependency graph given in the _dependency_graph target using the value
-# of the environment-overridable VIEW_POSTSCRIPT variable (currently set
-# to $(VIEW_POSTSCRIPT)). The postscript viewer is used because it
-# makes it easier to zoom in on the graph, a critical ability for
-# something so dense and mysterious.
-#
-# _all_sources:
-# List all .tex files in this directory.
-#
-# _sources:
-# Print out a list of all compilable sources in this directory. This is
-# useful for determining what make thinks it will be using as the
-# primary source for 'make all'.
-#
-# _scripts:
-# Print out a list of scripts that make knows can be used to generate
-# .tex files (described later).
-#
-# _all_stems:
-# Print a list of stems. These represent bare targets that can be
-# executed. Listing <stem> as a bare target will produce <stem>.pdf.
-#
-# _includes:
-# A list of .d files that would be included in this run if _includes
-# weren't specified. This target may be used alone or in conjunction
-# with other targets.
-#
-# _graphic_outputs:
-# A list of all generated .eps files
-#
-# _env:
-# A list of environment variables and their values. If supported by
-# your version of make, also a list of variables known to make.
-#
-# FILE TARGETS:
-#
-# %, %.pdf:
-# Build a PDF file from the corresponding %.tex file.
-#
-# If BUILD_STRATEGY=pdflatex, then this builds the pdf directly.
-# Otherwise, it uses this old-school but effective approach:
-#
-# latex -> dvips -> ps2pdf
-#
-# The BUILD_STRATEGY can be overridden in Makefile.ini in the same
-# directory. The default is pdflatex.
-#
-# Reasons for using latex -> dvips include the "psfrag" package, and the
-# generation of postscript instead of PDF. Arguments for using pdflatex
-# include "new and shiny" and "better supported." I can't argue with
-# either of those, and supporting them both didn't turn out to be that
-# difficult, so there you have it. Choices.
-#
-# %._show:
-# A phony target that builds the pdf file and then displays it using the
-# environment-overridable value of VIEW_PDF ($(VIEW_PDF)).
-#
-# %._graphics:
-# A phony target that generates all graphics on which %.pdf (or %.dvi)
-# depends.
-#
-# %.ps (only for BUILD_STRATEGY=latex):
-# Build a Postscript file from the corresponding %.tex file.
-# This is done using dvips. Paper size is automatically
-# extracted from the declaration
-#
-# \documentclass[<something>paper]
-#
-# or it is the system default.
-#
-# If using beamer (an excellent presentation class), the paper
-# size is ignored. More on this later.
-#
-# %.dvi (only for BUILD_STRATEGY=latex):
-# Build the DVI file from the corresponding %.tex file.
-#
-# %.ind:
-# Build the index for this %.tex file.
-#
-# %.gls:
-# Build the nomenclature glossary for this %.tex file.
-#
-# %.nls:
-# Build the (newer) nomenclature file for this %.tex file.
-#
-# %.eps:
-# Build an eps file from one of the following file types:
-#
-# .dot : graphviz
-# .gpi : gnuplot
-# .fig : xfig
-# .xvg : xmgrace
-# .svg : scalable vector graphics (goes through inkscape)
-# .png : png (goes through NetPBM)
-# .jpg : jpeg (goes through ImageMagick)
-# .eps.gz : gzipped eps
-#
-# The behavior of this makefile with each type is described in
-# its own section below.
-#
-# %.pstex{,_t} (only for BUILD_STRATEGY=latex):
-# Build a .pstex_t file from a .fig file.
-#
-# FEATURES:
-#
-# Optional Binary Directory:
-# If you create the _out_ directory in the same place as the makefile,
-# it will automatically be used as a dumping ground for .pdf (or .dvi,
-# .ps, and .pdf) output files.
-#
-# Alternatively, you can set the BINARY_TARGET_DIR variable, either as a
-# make argument or in Makefile.ini, to point to your directory of
-# choice. Note that no pathname wildcard expansion is done in the
-# makefile, so make sure that the path is complete before going in
-# there. E.g., if you want to specify something in your home directory,
-# use $$HOME/ instead of ~/ so that the shell expands it before it gets
-# to the makefile.
-#
-# External Program Dependencies:
-# Every external program used by the makefile is represented by an
-# ALLCAPS variable at the top of this file. This should allow you to
-# make judgments about whether your system supports the use of this
-# makefile. The list is available in the ALL_PROGRAMS variable and,
-# provided that you are using GNU make 3.80 or later (or you haven't
-# renamed this file to something weird like "mylatexmakefile" and like
-# invoking it with make -f) can be viewed using
-#
-# make _all_programs
-#
-# Additionally, the availability of these programs can be checked
-# automatically for you by running
-#
-# make _check_programs
-#
-# The programs are categorized according to how important they are and
-# what function they perform to help you decide which ones you really
-# need.
-#
-# Colorized Output:
-# The output of commands is colorized to highlight things that are often
-# important to developers. This includes {underfull,overfull}
-# {h,v}boxes, general LaTeX Errors, each stage of document building, and
-# the number of pages in the final document. The colors are obtained
-# using 'tput', so colorization should work pretty well on any terminal.
-#
-# The colors can be customized very simply by setting any of the
-# LATEX_COLOR_<CONTEXT> variables in your environment (see above).
-#
-# Predecessors to TeX Files:
-# Given a target <target>, if no <target>.tex file exists but a
-# corresponding script or predecessor file exists, then appropriate
-# action will be taken to generate the tex file.
-#
-# Currently supported script or predecessor languages are:
-#
-# sh: %.tex.sh
-# perl: %.tex.pl
-# python: %.tex.py
-#
-# Calls the script using the appropriate interpreter, assuming that
-# its output is a .tex file.
-#
-# The script is called thus:
-#
-# <interpreter> <script file name> <target tex file>
-#
-# and therefore sees exactly one parameter: the name of the .tex
-# file that it is to create.
-#
-# Why does this feature exist? I ran into this while working on
-# my paper dissertation. I wrote a huge bash script that used a
-# lot of sed to bring together existing papers in LaTeX. It
-# would have been nice had I had something like this to make my
-# life easier, since as it stands I have to run the script and
-# then build the document with make. This feature provides hooks
-# for complicated stuff that you may want to do, but that I have
-# not considered. It should work fine with included dependencies,
-# too.
-#
-# Scripts are run every time make is invoked. Some trickery is
-# employed to make sure that multiple restarts of make don't cause
-# them to be run again.
-#
-# reST: %.rst
-#
-# Runs the reST to LaTeX converter to generate a .tex file
-# If it finds a file names _rststyle_._include_.tex, uses it as
-# the "stylesheet" option to rst2latex.
-#
-# Note that this does not track sub-dependencies in rst files. It
-# assumes that the top-level rst file will change if you want a
-# rebuild.
-#
-# Dependencies:
-#
-# In general, dependencies are extracted directly from LaTeX output on
-# your document. This includes
-#
-# * Bibliography information
-# * \include or \input files (honoring \includeonly, too)
-# * Graphics files inserted by the graphicx package
-#
-# Where possible, all of these are built correctly and automatically.
-# In the case of graphics files, these are generated from the following
-# file types:
-#
-# GraphViz: .dot
-# GNUPlot: .gpi
-# XFig: .fig
-# XMgrace: .xvg
-# SVG: .svg
-# PNG: .png
-# JPEG: .jpg
-# GZipped EPS: .eps.gz
-#
-# If the file exists as a .eps already, it is merely used (and will not
-# be deleted by 'clean'!).
-#
-# LaTeX and BibTeX are invoked correctly and the "Rerun to get
-# cross-references right" warning is heeded a reasonable number of
-# times. In my experience this is enough for even the most troublesome
-# documents, but it can be easily changed (if LaTeX has to be run after
-# BibTeX more than three times, it is likely that something is moving
-# back and forth between pages, and no amount of LaTeXing will fix
-# that).
-#
-# \includeonly is honored by this system, so files that are not
-# specified there will not trigger a rebuild when changed.
-#
-# Beamer:
-# A special TeX source comment is recognized by this makefile (only when
-# BUILD_STRATEGY=latex, since this invokes psnup):
-#
-# %%[[:space:]]*BEAMER[[:space:]]*LARGE
-#
-# The presence of this comment forces the output of dvips through psnup
-# to enlarge beamer slides to take up an entire letter-sized page. This
-# is particularly useful when printing transparencies or paper versions
-# of the slides. For some reason landscape orientation doesn't appear
-# to work, though.
-#
-# If you want to put multiple slides on a page, use this option and then
-# print using mpage, a2ps, or psnup to consolidate slides. My personal
-# favorite is a2ps, but your mileage may vary.
-#
-# When beamer is the document class, dvips does NOT receive a paper size
-# command line attribute, since beamer does special things with sizes.
-#
-# GNUPlot Graphics:
-# When creating a .gpi file, DO NOT INCLUDE the "set terminal" or "set
-# output" commands! The makefile will include terminal information for
-# you. Besides being unnecessary and potentially harmful, including the
-# terminal definition in the .gpi file makes it harder for you, the one
-# writing the document, to preview your graphics, e.g., with
-#
-# gnuplot -persist myfile.gpi
-#
-# so don't do specify a terminal or an output file in your .gpi files.
-#
-# When building a gpi file into an eps file, there are several features
-# available to the document designer:
-#
-# Global Header:
-# The makefile searches for the files in the variable GNUPLOT_GLOBAL
-# in order:
-#
-# ($(GNUPLOT_GLOBAL))
-#
-# Only the first found is used. All .gpi files in the directory are
-# treated as though the contents of GNUPLOT_GLOBAL were directly
-# included at the top of the file.
-#
-# NOTE: This includes special comments! (see below)
-#
-# Font Size:
-# A special comment in a .gpi file (or a globally included file) of
-# the form
-#
-# ## FONTSIZE=<number>
-#
-# will change the font size of the GPI output. If font size is
-# specified in both the global file and the GPI file, the
-# specification in the individual GPI file is used.
-#
-# Grayscale Output:
-# GNUplot files also support a special comment to force them to be
-# output in grayscale *no matter what*:
-#
-# ## GRAY
-#
-# This is not generally advisable, since you can always create a
-# grayscale document using the forms mentioned above. But, if your
-# plot simply must be grayscale even in a document that allows
-# colors, this is how you do it.
-#
-# XFig Graphics:
-# No special handling is done with XFig, except when a global
-# grayscale method is used, e.g.
-#
-# make GRAY=1 document
-#
-# In these cases the .eps files is created using the -N switch to
-# fig2dev to turn off color output. (Only works with eps, not pstex
-# output)
-#
-# GraphVis Graphics:
-# Color settings are simply ignored here. The 'dot' program is used
-# to transform a .dot file into a .eps file.
-#
-# If you want, you can use the dot2tex program to convert dot files
-# to tex graphics. The default is to just call dot2tex with no
-# arguments, but you can change the DOT2TEX definition to include
-# options as needed (in your Makefile.ini).
-#
-# Note that, as with pstex, the makefile cannot use latex's own
-# output to discover all missing dot_t (output) files, since anytime
-# TeX includes TeX, it has to bail when it can't find the include
-# file. It can therefore only stop on the first missing file it
-# discovers, and we can't get a large list of them out easily.
-#
-# So, the makefile errors out if it's missing an included dot_t
-# file, then prompts the user to run this command manually:
-#
-# make all-dot2tex
-#
-# GZipped EPS Graphics:
-#
-# A .eps.gz file is sometimes a nice thing to have. EPS files can get
-# very large, especially when created from bitmaps (don't do this if you
-# don't have to). This makefile will unzip them (not in place) to
-# create the appropriate EPS file.

+# KNOWN ISSUES:
+# * The following occurs:
+# file with: \usepackage{named}\bibliographystyle{named}
+# Compile
+# change to: \usepackage{apalike}\bibliographystyle{apalike}
+# Compile again -- BARF!
+#
+# The workaround: make clean-nographics; make
+#
+# Note that we may not be able to fix this. LaTeX itself barfs
+# on this, not the makefile. The very first invocation of LaTeX
+# (when something like this has happened) reads the existing .aux
+# file and discovers invalid commands like \citeauthoryear that
+# are only valid in the package that was just removed. It then
+# tries to parse them and explodes. It's not at all clear to me
+# how to fix this. I tried removing the .aux files on the first
+# run of LaTeX, but that necessarily requires more subsequent
+# rebuilds on common edits. There does not appear to be a
+# graceful solution to this issue.

+# * Work on issue 76: bad backtick escape for some sed versions, failure

+# - Backed out 2>&1 to &> (doesn't work in sh)
+# - Backed out using . to source variables
+# Chris Monson (2010-03-22):
+# * Bumped version to 2.2.0-beta7
+# * Issue 72: Fix latex/bibtex invocation order for annotated bib styles
+# * Fixed informational output to reflect which LaTeX run we're on
+# * Fixed graphic detection to include graphics that are already there in
+# .d files
+# * Tightened up the .d file output to only make .d depend on graphic
+# *source* files. This means that building foo.d no longer
+# builds all of the graphics files on which foo.tex depends.
+# Had to use .SECONDEXPANSION trickery to make it work.
+# * Changed get-graphics to only accept a stem.
+# * Fixed build-once logic for scripted .tex to work better
+# * Made get-inputs sed script more maintainable.
+# * Moved Makefile.ini import up higher.
+# * Changed bare stems to not recursively invoke make
+# * Updated diff output to be more silent everywhere
+# * Added a MISSING comment to the .d file if stuff isn't found - forces
+# removal of .1st.make file, which often forces it to try again.
+# * Fixed broken graphics-target function
+# * Added sleep to .d file generation when stuff is missing - if it
+# builds too fast, make doesn't realize it needs to be reloaded,
+# and thus never discovers some deeper dependencies (especially
+# evident when graphics are included from scripted include
+# files).
+# Chris Monson (2010-03-17):
+# * Bumped version to 2.2.0-beta6
+# * Fixed bareword builds to actually work (requires static patterns)
+# * Fixed colorization to work with new paragraph stuff
+# Chris Monson (2010-03-17):
+# * Bumped version to 2.2.0-beta5
+# * Fixed graphic detection to be much more focused - splits log file
+# into paragraphs before doing pattern matching.
+# * Fixed make foo to work properly (recursively calls make foo.pdf)
+# * Fixed gpi -> pdf generation to not waste time building .eps *after*
+# the pdf already exists.
+# * Changed log copies to include MAKE_RESTARTS as part of the name.
+# * Fixed missing include file detection (also makes use of the paragraph
+# stuff) to detect missing scripted include files.
+# Chris Monson (2010-03-16):
+# * Bumped version to 2.2.0-beta4
+# * issue 70: .pdf not moved out of the way properly on first
+# compilation, resulting in early error detection failure.
+# * issue 74: fixed broken error on missing .aux files: the
+# implementation was masking real errors.
+# Chris Monson (2010-03-15):
+# * Bumped version to 2.2.0-beta3
+# * issue 71: Made the tput dependency optional
+# * issue 73: Made .tex targets not pull in .d files (building them from
+# scripts should not require a .d)
+# * issue 74: Output a much saner error when a .aux file is not produced
+# (e.g., when you are typing "make" without arguments in a
+# directory with included .tex files that are not named with
+# ._include_.)
+# Chris Monson (2010-03-11):
+# * Bumped version to 2.2.0-beta2
+# * Fixed clean-graphics to get rid of intermediate .eps files that may
+# be hanging around
+# * Added an automatic setting to use eps terminals in pdflatex mode for
+# gnuplot if it doesn't understand pdf.
+# * issue 66: Removed grayscale generation via magic suffix. Grayscale
+# generation is now only available via GRAY=1
+# * issue 68: Added explicit handling of LC_ALL for locale-aware tools
+# like "sort"
+# Chris Monson (2010-03-10):
+# * Bumped version to 2.2.0-beta1
+# * Fixed success message to handle output message in different places
+# * Added name of produced file to success message
+# Chris Monson (2010-03-10):
+# * Bumped version to 2.2.0-alpha3
+# * Added meaningful error message for wrong hyperref options
+# * Added meaningful error message for incorrect graphics extensions
+# Chris Monson (2010-03-09):
+# * Bumped version to 2.2.0-alpha2
+# * Updated graphics handling (gnuplot and fig generate pdf natively)
+# * Changed xmgrace to output monochrome natively
+# Chris Monson (2010-03-09):
+# * Bumped version to 2.2.0-alpha1 - major change!
+# * Support pdflatex natively and by default (issue 6 - a long time coming)
+# * Add ability to have a single $HOME/.latex-makefile/Makefile.ini for
+# all invocations
+# * Reworked graphic inclusion detection so that extensions need not be
+# specified for either build strategy (e.g.,
+# \includegraphics{test1.eps} -> \includegrahpics{test1})
+# * Changed log format to include filenames and line numbers
+# Chris Monson (2010-02-04):
+# * Bumped version to 2.1.43
+# * All of the following are for issue 63 (thanks to mojoh81):
+# * Added documentation about fixing Makefile.ini default target
+# * Added perl and python script targets
+# * Fixed run logic to allow included .tex files to be scripted (the
+# run-again logic now detects missing .tex files, and the MV
+# command has been switched out for a command that only invokes
+# MV if the files exist)
+# * Changed scripted generation to only run once per make invocation
+# * Added dependency on expr
+# Chris Monson (2010-01-19):
+# * Bumped version to 2.1.42
+# * issue 62: Added .brf extension to cleanable files (backrefs)
+# Chris Monson (2010-01-07):
+# * Bumped version to 2.1.41
+# * issue 60: bad makeindex runs now error out on subsequent tries
+# Chris Monson (2009-12-01):
+# * Bumped version to 2.1.40
+# * issue 36: build all indices (for e.g., splitidx usage)
+# * issue 59: clean up all generated files (including indices)
+# Chris Monson (2009-11-23):
+# * Bumped version to 2.1.39

+# Chris Monson (2009-09-25):
+# * Bumped version to 2.1.32
+# * Fixed so that a changed lol file will cause a rebuild

+# Chris Monson (2009-08-07):

+# Chris Monson (2009-05-15):
+# * Bumped version to 2.1.26
+# * Included patch for issue 9 from favonia - detects .fig changes for
+# pstex files during regular compilation, so long as the pstex
+# has been built at least once with make all-pstex.
+# Chris Monson (2009-03-27):
+# * Bumped version to 2.1.25

+# * Cleaned up documentation for various features, especially settable
+# variables.
+# * issue 28: support for png -> eps conversion (it even looks good!)
+# * issue 29: support for "neverclean" files in Makefile.ini
+# * issue 30: make ps2pdf14 the default - fall back when not there
+# Chris Monson (2009-03-09):
+# * Bumped version to 2.1.24
+# * issue 27: xmgrace support (thanks to rolandschulzhd)
+# Chris Monson (2008-10-23):
+# * Bumped version to 2.1.23

+# Chris Monson (2008-09-02):

+# sources and some documentation updates.
+# * Updated backup_patterns to be a bit more aggressive (also thanks to
+# Holger)
+# Chris Monson (2008-08-30):
+# * Bumped version to 2.1.21
+# * Added ability to specify onlysources.* variables to indicate the only
+# files that should *not* be considered includes. Thanks to Holger
+# <yllohy(a)googlemail.com> for this patch.
+# * Added an automatic include of Makefile.ini if it exists. Allows
+# settings to be made outside of this makefile.
+# Chris Monson (2008-05-21):
+# * Bumped version to 2.1.20
+# * Added manual pstex compilation support (run make all-pstex first)
+# * Removed all automatic pstex support. It was totally breaking
+# everything and is very hard to incorporate into the makefile
+# concept because it requires LaTeX to *fail* before it can
+# determine that it needs the files.
+# Chris Monson (2008-04-17):
+# * Bumped version to 2.1.19
+# * Changed the pstex build hack to be on by default
+# Chris Monson (2008-04-09):
+# * Bumped version to 2.1.18
+# * issue 16: fixed pstex build problems, seems nondeterministic. Added
+# gratuitious hack for testing: set PSTEX_BUILD_ALL_HACK=1.
+# Chris Monson (2008-04-09):
+# * Bumped version to 2.1.17
+# * issue 20: fixed accumulation of <pid>*.make files - wildcard was
+# refusing to work on files that are very recently created.
+# Chris Monson (2008-04-02):
+# * Bumped version to 2.1.16
+# * issue 19: Removed the use of "type" to fix broken "echo" settings
+# Chris Monson (2008-03-27):
+# * Bumped version to 2.1.15
+# * issue 18: Favors binary echo over builtin, as binary understands -n
+# * issue 16: Fixed handling of missing pstex_t files in the log
+# * issue 9: Added .SECONDARY target for .pstex files
+# Chris Monson (2008-03-21):
+# * Bumped version to 2.1.14
+# * Fixed broken aux file flattening, which caused included bibs to be
+# missed.

+# * Bumped version to 2.1.13

+# that are not graphics files.

+# Chris Monson (2008-01-24):
+# * Bumped version to 2.1.10
+# * Fixed to work when 'sh' is a POSIX shell like 'dash'
+# Chris Monson (2007-12-12):
+# * Bumped version to 2.1.9
+# * Fixed documentation and dependency graph for pstex files
+# Chris Monson (2007-12-12):
+# * Bumped version to 2.1.8
+# * Added basic pstex_t support for fig files (Issue 9 by favonia)
+# I still suggest that psfrag be used instead.

+# BSD SED NOTES
+#
+# BSD SED is not very nice compared to GNU sed, but it is the most
+# commonly-invoked sed on Macs (being based on BSD), so we have to cater to
+# it or require people to install GNU sed. It seems like the GNU
+# requirement isn't too bad since this makefile is really a GNU makefile,
+# but apparently GNU sed is much less common than GNU make in general, so
+# I'm supporting it here.
+#
+# Sad experience has taught me the following about BSD sed:
+#
+# * \+ is not understood to mean \{1,\}
+# * \| is meaningless (does not branch)
+# * \n cannot be used as a substitution character
+# * ? does not mean \{0,1\}, but is literal
+# * a\ works, but only reliably for a single line if subsequent lines
+# have forward slashes in them (as is the case in postscript)
+#
+# For more info (on the Mac) you can consult
+#
+# man -M /usr/share/man re_format
+#
+# And look for the word "Obsolete" near the bottom.

+# For sethsbcolor, the color is first converted to RGB, then to grayscale by

+# From

+#
+# Hi = int(floor(6 * H)) mod 6
+# f = 6 * H - Hi
+# p = V(1-S)
+# q = V(1-fS)

+# if Hi = 3: R G B <-- p q V

+# * There was a LaTeX error
+# * A needed file was not found
+# * Cross references need adjustment
+#
+# Behavior:
+# This rule is responsible for generating the following:
+# %.aux
+# %.d
+# %.aux.make
+# %.(pdf|dvi).1st.make (the .pdf or .dvi output file, moved)
+#
+# Steps:
+#
+# Run latex
+# Move .pdf or .dvi somewhere else (make no judgements about success)
+# Flatten the .aux file into another file
+# Add source dependencies
+# Add graphic dependencies
+# Add bib dependencies
+#
+# Create cookies for various suffixes that may represent files that
+# need to be read by LaTeX in order for it to function properly.
+#
+# Note that if some of the dependencies are discovered because they turn
+# up missing in the log file, we really need the .d file to be reloaded.
+# Adding a sleep command helps with this. Otherwise make is extremely
+# nondeterministic, sometimes working, sometimes not.
+#
+# Usually we can force this by simply removing the generated pdf file and
+# not creating a .1st.make file..

+# Generates a number of possible output files from a LaTeX document and its
+# various dependencies. Handles .bib files, \include and \input, and .eps
+# graphics. All dependencies are handled automatically by running LaTeX over
+# the source.
+#
+# USAGE:
+#
+# make [GRAY=1] [VERBOSE=1] [SHELL_DEBUG=1] <target(s)>
+#
+# STANDARD OPTIONS:
+# GRAY:
+# Setting this variable forces all recompiled graphics to be grayscale.
+# It is useful when creating a document for printing. The default is
+# to allow colors. Note that it only changes graphics that need to be
+# rebuilt! It is usually a good idea to do a 'make clean' first.
+#
+# VERBOSE:
+# This turns off all @ prefixes for commands invoked by make. Thus,
+# you get to see all of the gory details of what is going on.
+#
+# SHELL_DEBUG:
+# This enables the -x option for sh, meaning that everything it does is
+# echoed to stderr. This is particularly useful for debugging
+# what is going on in $$(shell ...) invocations. One of my favorite
+# debugging tricks is to do this:
+#
+# make -d SHELL_DEBUG=1 VERBOSE=1 2>&1 | less
+#
+# KEEP_TEMP:
+# When set, this allows .make and other temporary files to stick around
+# long enough to do some debugging. This can be useful when trying to
+# figure out why gnuplot is not doing the right things, for example
+# (e.g., look for *head.make).
+#
+# STANDARD AUXILIARY FILES:
+#
+# Variables.ini (formerly Makefile.ini, which still works)
+#
+# This file can contain variable declarations that override various
+# aspects of the makefile. For example, one might specify
+#
+# neverclean := *.pdf *.ps
+# onlysources.tex := main.tex
+# LATEX_COLOR_WARNING := 'bold red uline'
+#
+# And this would override the neverclean setting to ensure that pdf
+# and ps files always remain behind, set the makefile to treat all
+# .tex files that are not "main.tex" as includes (and therefore not
+# default targets). It also changes the LaTeX warning output to be
+# red, bold, and underlined.
+#
+# There are numerous variables in this file that can be overridden in
+# this way. Search for '?=' to find them all.
+#
+# The Variables.ini is imported before *anything else* is done, so go
+# wild with your ideas for changes to this makefile in there. It
+# makes it easy to test them before submitting patches.
+#
+# If you're adding rules or targets, however, see Targets.ini below.
+#
+# Targets.ini
+#
+# This is included much later in the makefile, after all variables and
+# targets are defined. This is where you would put new make rules,
+# e.g.,
+#
+# generated.tex: generating_script.weird_lang depA depB
+# ./generating_script.weird_lang > $$@
+#
+# In this file, you have access to all of the variables that the
+# makefile creates, like $(onlysources.tex). While accessing those can
+# be somewhat brittle (they are implementation details and may change),
+# it is a great way to test your ideas when submitting feature requests.
+#
+# STANDARD ENVIRONMENT VARIABLES:
+#
+# LATEX_COLOR_WARNING '$(LATEX_COLOR_WARNING)'
+# LATEX_COLOR_ERROR '$(LATEX_COLOR_ERROR)'
+# LATEX_COLOR_UNDERFULL '$(LATEX_COLOR_UNDERFULL)'
+# LATEX_COLOR_OVERFULL '$(LATEX_COLOR_OVERFULL)'
+# LATEX_COLOR_PAGES '$(LATEX_COLOR_PAGES)'
+# LATEX_COLOR_BUILD '$(LATEX_COLOR_BUILD)'
+# LATEX_COLOR_GRAPHIC '$(LATEX_COLOR_GRAPHIC)'
+# LATEX_COLOR_DEP '$(LATEX_COLOR_DEP)'
+# LATEX_COLOR_SUCCESS '$(LATEX_COLOR_SUCCESS)'
+# LATEX_COLOR_FAILURE '$(LATEX_COLOR_FAILURE)'
+#
+# These may be redefined in your environment to be any of the following:
+#
+# black
+# red
+# green
+# yellow
+# blue
+# magenta
+# cyan
+# white
+#
+# Bold or underline may be used, as well, either alone or in combination
+# with colors:
+#
+# bold
+# uline
+#
+# Order is not important. You may want, for example, to specify:
+#
+# export LATEX_COLOR_SUCCESS='bold blue uline'
+#
+# in your .bashrc file. I don't know why, but you may want to.
+#
+# STANDARD TARGETS:
+#
+# all:
+# Make all possible documents in this directory. The documents are
+# determined by scanning for .tex and .tex.sh (described in more detail
+# later) and omitting any file that ends in ._include_.tex or
+# ._nobuild_.tex. The output is a set of .pdf files.
+#
+# If you wish to omit files without naming them with the special
+# underscore names, set the following near the top of the Makefile,
+# or (this is recommended) within a Makefile.ini in the same directory:
+#
+# includes.tex := file1.tex file2.tex
+#
+# This will cause the files listed to be considered as include files.
+#
+# If you have only few source files, you can set
+#
+# onlysources.tex := main.tex
+#
+# This will cause only the source files listed to be considered in
+# dependency detection. All other .tex files will be considered as
+# include files. Note that these options work for *any* source type,
+# so you could do something similar with includes.gpi, for example.
+# Note that this works for *any valid source* target. All of the
+# onlysources.* variables are commented out in the shipping version of
+# this file, so it does the right thing when they simply don't exist.
+# The comments are purely documentation. If you know, for example, that
+# file.mycoolformat is supported by this Makefile, but don't see the
+# "onlysources.mycoolformat" declared in the comments, that doesn't mean
+# you can't use it. Go ahead and set "onlysources.mycoolformat" and it
+# should do the right thing.
+#
+# show:
+# Builds and displays all documents in this directory. It uses the
+# environment-overridable value of VIEW_PDF (currently $(VIEW_PDF)) to
+# do its work.
+#
+# all-graphics:
+# Make all of the graphics in this directory.
+#
+# all-pstex (only for BUILD_STRATEGY=latex):
+# Build all fig files into pstex and pstex_t files. Gray DOES NOT WORK.
+#
+# all-gray-pstex (only for BUILD_STRATEGY=latex):
+# Build all fig files into grayscale pstex and pstex_t files.
+#
+# all-dot2tex:
+# Build all dot files into tex files.
+#
+# show-graphics:
+# Builds and displays all graphics in this directory. Uses the
+# environment-overridable value of VIEW_GRAPHICS (currently
+# $(VIEW_GRAPHICS)) to do its work.
+#
+# clean:
+# Remove ALL generated files, leaving only source intact.
+# This will *always* skip files mentioned in the "neverclean" variable,
+# either in this file or specified in Makefile.ini:
+#
+# neverclean := *.pdf *.ps
+#
+# The neverclean variable works on all "clean" targets below, as well.
+#
+# clean-graphics:
+# Remove all generated graphics files.
+#
+# clean-backups:
+# Remove all backup files: $(backup_patterns)
+# (XFig and other editors have a nasty habit of leaving them around)
+# Also removes Makefile-generated .temp files
+#

+#
+# clean-deps:

+#
+# _check_programs:
+# Checks your system for the needed software and reports what it finds.
+#
+# _check_gpi_files:
+# Checks the .gpi files in the current directory for common errors, such
+# as specification of the terminal or output file inside of the gpi file
+# itself.
+#
+# _dependency_graph:
+# Outputs a .dot file to stdout that represents a graph of LaTeX
+# dependencies. To see it, use the _show_dependency_graph target or

+#
+# make _dependency_graph > graph.dot
+# dot -T ps -o graph.eps graph.dot
+# gv graph.eps
+#
+# _show_dependency_graph:
+# Makes viewing the graph simple: extracts, builds and displays the
+# dependency graph given in the _dependency_graph target using the value
+# of the environment-overridable VIEW_POSTSCRIPT variable (currently set
+# to $(VIEW_POSTSCRIPT)). The postscript viewer is used because it
+# makes it easier to zoom in on the graph, a critical ability for
+# something so dense and mysterious.
+#
+# _all_sources:
+# List all .tex files in this directory.
+#
+# _sources:
+# Print out a list of all compilable sources in this directory. This is
+# useful for determining what make thinks it will be using as the
+# primary source for 'make all'.
+#
+# _scripts:
+# Print out a list of scripts that make knows can be used to generate
+# .tex files (described later).
+#
+# _all_stems:
+# Print a list of stems. These represent bare targets that can be
+# executed. Listing <stem> as a bare target will produce <stem>.pdf.
+#
+# _includes:
+# A list of .d files that would be included in this run if _includes
+# weren't specified. This target may be used alone or in conjunction
+# with other targets.
+#
+# _graphic_outputs:
+# A list of all generated .eps files
+#
+# _env:
+# A list of environment variables and their values. If supported by
+# your version of make, also a list of variables known to make.
+#
+# FILE TARGETS:
+#
+# %, %.pdf:
+# Build a PDF file from the corresponding %.tex file.
+#
+# If BUILD_STRATEGY=pdflatex, then this builds the pdf directly.
+# Otherwise, it uses this old-school but effective approach:
+#
+# latex -> dvips -> ps2pdf
+#
+# The BUILD_STRATEGY can be overridden in Makefile.ini in the same
+# directory. The default is pdflatex.
+#
+# Reasons for using latex -> dvips include the "psfrag" package, and the
+# generation of postscript instead of PDF. Arguments for using pdflatex
+# include "new and shiny" and "better supported." I can't argue with
+# either of those, and supporting them both didn't turn out to be that
+# difficult, so there you have it. Choices.
+#
+# %._show:
+# A phony target that builds the pdf file and then displays it using the
+# environment-overridable value of VIEW_PDF ($(VIEW_PDF)).
+#
+# %._graphics:
+# A phony target that generates all graphics on which %.pdf (or %.dvi)
+# depends.
+#
+# %.ps (only for BUILD_STRATEGY=latex):
+# Build a Postscript file from the corresponding %.tex file.
+# This is done using dvips. Paper size is automatically
+# extracted from the declaration
+#
+# \documentclass[<something>paper]
+#
+# or it is the system default.
+#
+# If using beamer (an excellent presentation class), the paper
+# size is ignored. More on this later.
+#
+# %.dvi (only for BUILD_STRATEGY=latex):
+# Build the DVI file from the corresponding %.tex file.
+#
+# %.ind:
+# Build the index for this %.tex file.
+#
+# %.gls:
+# Build the nomenclature glossary for this %.tex file.
+#
+# %.nls:
+# Build the (newer) nomenclature file for this %.tex file.
+#
+# %.eps:
+# Build an eps file from one of the following file types:
+#
+# .dot : graphviz
+# .gpi : gnuplot
+# .fig : xfig
+# .xvg : xmgrace
+# .svg : scalable vector graphics (goes through inkscape)
+# .png : png (goes through NetPBM)
+# .jpg : jpeg (goes through ImageMagick)
+# .eps.gz : gzipped eps
+#
+# The behavior of this makefile with each type is described in
+# its own section below.
+#
+# %.pstex{,_t} (only for BUILD_STRATEGY=latex):
+# Build a .pstex_t file from a .fig file.
+#
+# FEATURES:
+#
+# Optional Binary Directory:
+# If you create the _out_ directory in the same place as the makefile,
+# it will automatically be used as a dumping ground for .pdf (or .dvi,
+# .ps, and .pdf) output files.
+#
+# Alternatively, you can set the BINARY_TARGET_DIR variable, either as a
+# make argument or in Makefile.ini, to point to your directory of
+# choice. Note that no pathname wildcard expansion is done in the
+# makefile, so make sure that the path is complete before going in
+# there. E.g., if you want to specify something in your home directory,
+# use $$HOME/ instead of ~/ so that the shell expands it before it gets
+# to the makefile.
+#
+# External Program Dependencies:
+# Every external program used by the makefile is represented by an
+# ALLCAPS variable at the top of this file. This should allow you to
+# make judgments about whether your system supports the use of this
+# makefile. The list is available in the ALL_PROGRAMS variable and,
+# provided that you are using GNU make 3.80 or later (or you haven't
+# renamed this file to something weird like "mylatexmakefile" and like
+# invoking it with make -f) can be viewed using
+#
+# make _all_programs
+#
+# Additionally, the availability of these programs can be checked
+# automatically for you by running
+#
+# make _check_programs
+#
+# The programs are categorized according to how important they are and
+# what function they perform to help you decide which ones you really
+# need.
+#
+# Colorized Output:
+# The output of commands is colorized to highlight things that are often
+# important to developers. This includes {underfull,overfull}
+# {h,v}boxes, general LaTeX Errors, each stage of document building, and
+# the number of pages in the final document. The colors are obtained
+# using 'tput', so colorization should work pretty well on any terminal.
+#
+# The colors can be customized very simply by setting any of the
+# LATEX_COLOR_<CONTEXT> variables in your environment (see above).
+#
+# Predecessors to TeX Files:
+# Given a target <target>, if no <target>.tex file exists but a
+# corresponding script or predecessor file exists, then appropriate
+# action will be taken to generate the tex file.
+#
+# Currently supported script or predecessor languages are:
+#
+# sh: %.tex.sh
+# perl: %.tex.pl
+# python: %.tex.py
+#
+# Calls the script using the appropriate interpreter, assuming that
+# its output is a .tex file.
+#
+# The script is called thus:
+#
+# <interpreter> <script file name> <target tex file>
+#
+# and therefore sees exactly one parameter: the name of the .tex
+# file that it is to create.
+#
+# Why does this feature exist? I ran into this while working on
+# my paper dissertation. I wrote a huge bash script that used a
+# lot of sed to bring together existing papers in LaTeX. It
+# would have been nice had I had something like this to make my
+# life easier, since as it stands I have to run the script and
+# then build the document with make. This feature provides hooks
+# for complicated stuff that you may want to do, but that I have
+# not considered. It should work fine with included dependencies,
+# too.
+#
+# Scripts are run every time make is invoked. Some trickery is
+# employed to make sure that multiple restarts of make don't cause
+# them to be run again.
+#
+# reST: %.rst
+#
+# Runs the reST to LaTeX converter to generate a .tex file
+# If it finds a file names _rststyle_._include_.tex, uses it as
+# the "stylesheet" option to rst2latex.
+#
+# Note that this does not track sub-dependencies in rst files. It
+# assumes that the top-level rst file will change if you want a
+# rebuild.
+#
+# Dependencies:
+#
+# In general, dependencies are extracted directly from LaTeX output on
+# your document. This includes
+#
+# * Bibliography information
+# * \include or \input files (honoring \includeonly, too)
+# * Graphics files inserted by the graphicx package
+#
+# Where possible, all of these are built correctly and automatically.
+# In the case of graphics files, these are generated from the following
+# file types:
+#
+# GraphViz: .dot
+# GNUPlot: .gpi
+# XFig: .fig
+# XMgrace: .xvg
+# SVG: .svg
+# PNG: .png
+# JPEG: .jpg
+# GZipped EPS: .eps.gz
+#
+# If the file exists as a .eps already, it is merely used (and will not
+# be deleted by 'clean'!).
+#
+# LaTeX and BibTeX are invoked correctly and the "Rerun to get
+# cross-references right" warning is heeded a reasonable number of
+# times. In my experience this is enough for even the most troublesome
+# documents, but it can be easily changed (if LaTeX has to be run after
+# BibTeX more than three times, it is likely that something is moving
+# back and forth between pages, and no amount of LaTeXing will fix
+# that).
+#
+# \includeonly is honored by this system, so files that are not
+# specified there will not trigger a rebuild when changed.
+#
+# Beamer:
+# A special TeX source comment is recognized by this makefile (only when
+# BUILD_STRATEGY=latex, since this invokes psnup):
+#
+# %%[[:space:]]*BEAMER[[:space:]]*LARGE
+#
+# The presence of this comment forces the output of dvips through psnup
+# to enlarge beamer slides to take up an entire letter-sized page. This
+# is particularly useful when printing transparencies or paper versions
+# of the slides. For some reason landscape orientation doesn't appear
+# to work, though.
+#
+# If you want to put multiple slides on a page, use this option and then
+# print using mpage, a2ps, or psnup to consolidate slides. My personal
+# favorite is a2ps, but your mileage may vary.
+#
+# When beamer is the document class, dvips does NOT receive a paper size
+# command line attribute, since beamer does special things with sizes.
+#
+# GNUPlot Graphics:
+# When creating a .gpi file, DO NOT INCLUDE the "set terminal" or "set
+# output" commands! The makefile will include terminal information for
+# you. Besides being unnecessary and potentially harmful, including the
+# terminal definition in the .gpi file makes it harder for you, the one
+# writing the document, to preview your graphics, e.g., with
+#
+# gnuplot -persist myfile.gpi
+#
+# so don't do specify a terminal or an output file in your .gpi files.
+#
+# When building a gpi file into an eps file, there are several features
+# available to the document designer:
+#
+# Global Header:
+# The makefile searches for the files in the variable GNUPLOT_GLOBAL
+# in order:
+#
+# ($(GNUPLOT_GLOBAL))
+#
+# Only the first found is used. All .gpi files in the directory are
+# treated as though the contents of GNUPLOT_GLOBAL were directly
+# included at the top of the file.
+#
+# NOTE: This includes special comments! (see below)
+#
+# Font Size:
+# A special comment in a .gpi file (or a globally included file) of
+# the form
+#
+# ## FONTSIZE=<number>
+#
+# will change the font size of the GPI output. If font size is
+# specified in both the global file and the GPI file, the
+# specification in the individual GPI file is used.
+#
+# Grayscale Output:
+# GNUplot files also support a special comment to force them to be
+# output in grayscale *no matter what*:
+#
+# ## GRAY
+#
+# This is not generally advisable, since you can always create a
+# grayscale document using the forms mentioned above. But, if your
+# plot simply must be grayscale even in a document that allows
+# colors, this is how you do it.
+#
+# XFig Graphics:
+# No special handling is done with XFig, except when a global
+# grayscale method is used, e.g.
+#
+# make GRAY=1 document
+#
+# In these cases the .eps files is created using the -N switch to
+# fig2dev to turn off color output. (Only works with eps, not pstex
+# output)
+#
+# GraphVis Graphics:
+# Color settings are simply ignored here. The 'dot' program is used
+# to transform a .dot file into a .eps file.
+#
+# If you want, you can use the dot2tex program to convert dot files
+# to tex graphics. The default is to just call dot2tex with no
+# arguments, but you can change the DOT2TEX definition to include
+# options as needed (in your Makefile.ini).
+#
+# Note that, as with pstex, the makefile cannot use latex's own
+# output to discover all missing dot_t (output) files, since anytime
+# TeX includes TeX, it has to bail when it can't find the include
+# file. It can therefore only stop on the first missing file it
+# discovers, and we can't get a large list of them out easily.
+#
+# So, the makefile errors out if it's missing an included dot_t
+# file, then prompts the user to run this command manually:
+#
+# make all-dot2tex
+#
+# GZipped EPS Graphics:
+#
+# A .eps.gz file is sometimes a nice thing to have. EPS files can get
+# very large, especially when created from bitmaps (don't do this if you
+# don't have to). This makefile will unzip them (not in place) to
+# create the appropriate EPS file.

+\section{Introduction}
+\label{sec:introduction}
+
+This document discusses current considerations and plans for evaluating approaches for moving to a datagram transport in Tor.
+For background, refer to Murdoch~\cite{datagram-comparison}.
+
+\subsection{Simulation vs Emulation}
+
+An important design choice for the experiments is whether we run experiments on simulated Tor software, or on the real (but modified) Tor implementation.
+The advantage of the former is that it should be easier: only the timing of cells needs to be simulated and nodes have full visibility of the state of other nodes.
+The advantage of the latter is that the simulation is more realistic.
+
+In the absence of a suitable model of Tor, it has been decided to modify the existing Tor implementation.
+The Tor network can then be emulated using ExperimenTor~\cite{experimentor} and Shadow~\cite{shadow}.
+This does require implementing a datagram variant of Tor sufficiently well to allow clients to route traffic with realistic performance characteristics.
+
+\subsection{End-to-end vs Hop-by-hop}
+
+A design choice for a datagram variant of Tor is the end points of the reliability protocol.
+Options include OP to destination server (\ie Tor routes IP packets), OP to exit node (\ie the exit node reassembles TCP streams and re-segments them), or hop-by-hop (\ie each node re-assembles streams).
+OP to destination server is the most versatile, but makes implementing exit-policies difficult.
+OP to exit node is the closest approximation of the end-to-end principle for Internet design, but means that any dropped packet will need to be retransmitted all the way along the circuit.
+Hop-by-hop is not as versatile as either of the end-to-end variants, but by providing a reliable tunnel to all nodes it means that Tor's existing cell cryptography and relay protocol could remain unchanged.
+
+The ease of implementation, coupled with the fact that evaluation has shown good results from the hop-by-hop approach make it the most suitable for further development.
+End-to-end variants may however still be worthwhile to examing if time is available.
+
+\subsection{Transport Protocol}
+
+Reardon's original implementation used the TCP Daytona stack, which is not available under a Tor compatible license and so cannot be used.
+However there are a number of more suitable alternatives.
+
+\subsubsection{$\upmu$tp}
+
+The libutp implementation is widely deployed in BitTorrent, although its performance goal of yielding to TCP is not ideal.
+
+\subsubsection{FreeBSD network stack}
+
+The FreeBSD network stack is being ported to userspace by Kip Macy, and will provide TCP and SCTP.
+
+\subsubsection{SCTP}
+
+A userspace SCTP stack is available\footnote{\url{http://sctp.fh-muenster.de/sctp-user-land-stack.html}}.
+
+\subsubsection{CurveCP}
+
+The CurveCP stack is available, although has not had as extensive testing as the other options.
+
+\section{Development plans}
+
+Future plans will need to encompass four areas.
+
+\subsection{Network model}
+
+A model of the simulated Tor network will need to be developed.
+This should include node characteristics (CPU, possibly memory) and network characteristics (capacity, latency, other traffic usage).
+
+\subsection{User/server model}
+
+A model will need to be developed of the demands users put on the network, and how servers respond to requests.
+
+\subsection{Tor implementation}
+
+Tor will need to be updated to use each of the transport protocols to be tested.
+
+\subsection{Metrics and Experimentation}
+
+Finally, performance metrics will need to be developed, and experiments run.
+
+\section{Schedule and participants}
+
+Participants who have offered to help are:
+\begin{itemize}
+\item Rob Jansen (Shadow) working with Kevin Bauer (ExperimenTor) on modeling Tor.
+\item Kevin and Mashael AlSabah will be getting Joel Reardon's code working on current Tor
+\item Rob will be focusing on hop-by-hop transports, starting with $\upmu$TP. He is currently busy on another project, but will be able to return in early May.
+\item Mashael will focus on end-to-end transports, including analyzing how it affects security
+\item Steven Murdoch will try to pull everything together and do everything else

+20:09 armadev> sjmurdoch: one topic we might also cover is that there's debate in the systems world about whether tcp end-to-end (alice to exit) is better or worse than a bunch
+ of pairwise tcp connections strung together (alice to 1, 1 to 2, 2 to 3)
+20:26 armadev> sjmurdoch: another topic to cover is how many of the congestion control / performance optimizations in tor are actually orthogonal to the choice of transport.
+ e.g. bandwidth measurement and load balancing, or rate limiting, or the circuit priority designs, or mike's circuit build timeout

+\section{Background}
+
+A number of performance-related problems have been noted with the current Tor
+architecture, resulting in many users restricting their Tor usage to only tasks
+which are of high sensitivity, or not using Tor at all.
+The most comprehensive analysis of Tor's performance was performed by
+Reardon~\cite{reardon-thesis}.
+In this work, the author identified the major cause of latency was delay in the
+output queue at Tor nodes, resulting from TCP flow control.
+This delay is considered higher than necessary due to:
+\begin{itemize}
+\item High-bandwidth streams unfairly trigger congestion avoidance on
+low-bandwidth streams;
+\item Packet dropping and re-ordering on one stream triggers unnecessary delay on
+other streams.
+\end{itemize}
+
+It has been proposed that to improve performance, the node-to-node
+communication should be by unreliable datagrams (UDP), rather than the current
+reliable in-order streams (TCP).
+This is hoped to improve Tor performance by:
+\begin{itemize}
+\item Allowing better end-to-end congestion management;
+\item Reducing queue lengths on nodes;
+\item Preventing cell-loss on one circuit delaying cells on other circuits.
+\end{itemize}
+Also, moving to an underlying datagram transport may make it easier to support
+transporting UDP in addition to TCP. More detailed analysis has been performed
+by Reardon and Goldberg~\cite{reardon-usenix}.
+
+\section{Tor's current architecture}
+
+To understand proposals for modifications to Tor, it is helpful to understand
+the current architecture.
+This section will describe Tor's protocol stack, and while it does not use
+exactly the same terminology as the Tor Protocol Specification, the description
+chosen is designed to make it easier to compare with alternative proposals.
+
+\subsection{Tor circuit extension}
+
+\begin{figure}
+\begin{center}
+\includegraphics[scale=0.7]{tor-extension}
+\end{center}
+\caption{\label{fig:tor-extension}Protocol stack active when extending a
+circuit}
+\end{figure}
+
+\prettyref{fig:tor-extension} shows the scenario when the circuit Initiator
+(normally termed the Onion Proxy) has a circuit which currently goes through one
+intermediate hop, and terminates on Previous. The Initiator then wishes to
+extend this circuit to terminate on Next. In this scenario the active layers
+are:
+
+\paragraph{IP} The host operating system IP stack (and lower layers) is
+responsible for \textbf{routing IP
+packets} between the host and other Tor-nodes.
+
+\paragraph{TCP} The host operating system TCP stack is responsible for providing
+\textbf{hop-by-hop congestion control}, \textbf{in-order delivery}, and
+\textbf{reliability} for TLS data.
+
+\paragraph{TLS} The TLS stack built into Tor (OpenSSL) is responsible for providing
+\textbf{hop-by-hop authentication}, \textbf{integrity} and
+\textbf{confidentiality}.
+
+\paragraph{Circuit} The Tor circuit cryptography layer is responsible for
+providing \textbf{confidentiality}. It also \textbf{de-multiplexes} between
+different circuits being carried by TLS connections and performs
+\textbf{label-switching} routing.
+
+While the Tor software on all nodes is identical, on intermediate nodes, only
+the layers up to and including \figref{Circuit} are active.
+Cells received from the incoming TLS connection are decrypted, label-switched,
+and routed to the outgoing TLS connection according to its routing table.
+
+\paragraph{Cell auth} Tor's cell authentication provides \textbf{end-to-end integrity}
+
+\paragraph{Setup} Tor's setup protocol provides \textbf{connection setup and
+management} tightly coupled to \textbf{end-to-end authentication and key
+exchange}. It is also responsible for end-to-end congestion control.
+
+The \figref{Setup} layer can interact directly with the \figref{TLS} layer when
+a control message is intended for the directly connected party, or via the
+\figref{Circuit} and \figref{Cell Auth} layers when the control message must
+pass through intermediaries.
+
+\subsubsection{The circuit extension process}
+
+In the case of circuit extension, the \figref{Initiator} first wraps the control
+message with authentication (\figref{Cell Auth}), two layers of
+encryption (\figref{Circuit}) and passes the cell down to TLS.
+
+\figref{Intermediate} then removes one layer of encryption and passes the cell down
+to TLS.
+
+When \figref{Previous} receives the cell from \figref{TLS}, the final layer of
+encryption is removed, the authentication tag is verified and the control
+message is processed.
+\figref{Previous} will see that the control message indicates circuit extension
+(\texttt{RELAY\_EXTEND}), and will send a \texttt{CREATE} control message to
+\figref{Next}.
+
+\subsection{Data transport}
+
+\begin{figure}
+\includegraphics[scale=0.7]{tor-data}
+\caption{\label{fig:tor-data}Protocol stack active when carrying data}
+\end{figure}
+
+When an application wishes to send data over Tor, some additional layers are
+brought into play.
+
+\paragraph{Application} The client application wishes to send some stream data
+over Tor.
+
+\paragraph{SOCKS} The \figref{SOCKS} layer encapsulates the stream data with a
+SOCKS header and carries out the SOCKS handshake.
+
+\paragraph{TCP and IP} In addition to transporting TLS data between Tor nodes,
+the host TCP/IP stack is also responsible for transporting the SOCKS stream to
+the Tor initiator (typically running on the same host as the application).
+
+\paragraph{Gateway} At the Initiator, Tor's \figref{Gateway} layer receives SOCKS
+packets from the application SOCKS layer, extracts the payload data, and splits
+it into cells. These are then encapsulated in the same way as control messages,
+and passed to the \figref{Exit} node via any intermediaries. This layer is also
+responsible for multiplexing multiple application streams over one circuit.
+
+At the Exit, the \figref{Gateway} layer receives payload data encapsulated in
+cells, and sends it out to the appropriate host via the host TCP/IP stack.
+
+\paragraph{Cell Auth, Circuit, TLS} These layers are unchanged as intermediate
+nodes cannot differentiate between control and data transport cells.
+
+\subsubsection{The data transport process}
+
+Based on the SOCKS handshake between \figref{SOCKS} on the \figref{Application},
+the Initiator may create and extend circuits as necessary until it has
+established a circuit with the \figref{Exit}.
+
+The \figref{Gateway} layer at the Initiator then then instructs the
+\figref{Gateway} layer at the exit to make a plain TCP connection to the host
+requested by Initiator, and send the application stream data to it.
+
+\section{Alternative architecture proposals}
+
+This section discusses alternative architectures for Tor, involving the addition
+of a datagram hop-by-hop transport.
+
+\subsection{Reardon}
+
+\begin{figure}
+\includegraphics[scale=0.7]{reardon-data}
+\caption{\label{fig:reardon-data}The main change in Reardon's proposal is to have 1:1 circuit per TCP connection mapping, rather than Tor's n:1, but TCP connections are still hop-by-hop in both schemes.
+To stop the individual connections being apparent to a network observer, TCP frames are wrapped in DTLS encryption.
+To allow this wrapping to be performed, a user-space TCP stack is employed, which has the added advantage of reducing usage of kernel-level sockets (a scarce resource on some platforms) and allowing greater customization of congestion control.}
+\end{figure}
+
+Reardon and Goldberg~\cite{reardon-usenix} propose replacing the \figref{TLS}
+layer with DTLS (a datagram variant of DTLS) and replacing \figref{TCP} with
+UDP, as shown in \prettyref{fig:reardon-data}.
+DTLS still provides confidentiality and authenticity, however UDP does not
+provide reliability, in-order delivery, or congestion control.
+
+The authors therefore propose adding TCP back in, but with each pair of nodes
+having a separate hop-by-hop user-space TCP connection for each circuit, rather than one
+kernel-space TCP connection for all circuits.
+For efficiency, the user-space TCP header is compressed by removing redundant
+fields.
+
+Since the user-space TCP provides reliable in-order delivery of Tor cells, there
+needs to be no change to the cell encryption or authentication. A user-space TCP stack
+also allows more versatile congestion management; for example dropping cells before
+they acknowledged when the corresponding exit circuit is congested.
+
+\subsection{Viecco: UDP-OR}
+
+Viecco~\cite{viecco}, as shown in \prettyref{fig:viecco-data} uses end-to-end TCP rather than the hop-by-hop approach of Reardon, and uses the
+host TCP stack rather than a user-space one.
+Also, control traffic is not sent within a TCP stream so is unreliable.
+If messages are lost the initiator must detect a timeout and repeat the action.
+TCP is end-to-end, thereby allowing middle nodes to drop and re-order packets, but leaving open the possibility of fingerprinting attacks.
+
+\begin{figure}
+\includegraphics[scale=0.7]{viecco-data}
+\caption{\label{fig:viecco-data}In the architecture proposed by Viecco, the initiator TCP stack is responsible for splitting SOCKS payload data into TCP frames.
+Tor would then transport these frames directly (after compressing and sanitizing some fields), for it to be reassembled by the host TCP stack on the exit node, have any SOCKS header removed, and be emitted again via the host TCP stack.
+Intermediate nodes use UDP, with reliability and congestion control managed by the initiator and exit.
+A custom link encryption/authentication scheme is used, but DTLS could equally take its place.
+The Circuit and Cell Auth cryptography schemes are updated to handle dropped or re-ordered cells.}
+\end{figure}
+
+\subsection{Freedom 2.0}
+
+\begin{figure}
+\includegraphics[scale=0.7]{freedom-data}
+\caption{Like Viecco's proposal, TCP is end-to-end, however in Freedom this is initiator to server, rather than initiator to exit.}
+\end{figure}
+
+Full details on Freedom~\cite{freedom2-arch} is not available but it appears that, while like Viecco's proposal, TCP is end-to-end, in Freedom the ends are the Initiator and destination Server, rather than Initiator and Exit.
+Like Viecco's proposal, the initiator is responsible for reliability, through its host TCP stack.
+However, SOCKS is not used (Freedom captures application data in the host network stack), and control traffic is sent over TCP rather than UDP, and thus may assume reliable in-order delivery.
+Freedom also performs protocol filtering, before the data stream is split into TCP frames.
+
+\subsection{Cebolla and IPPriv}
+
+Other examples of the Freedom design are Cebolla~\cite{brown} and IPPriv~\cite{kiraly}.
+Cebolla is notable for having a restricted topology, however in terms of
+transport protocol it appears to be similar to Freedom. IP packets are captured
+through a tun device on the initiator, encrypted, and then sent as UDP packets.
+At the exit nodes, IP packets are emitted over the tun device. As such, the
+characteristics of the initiator TCP stack are exposed to the destination.
+
+Kiraly~\cite{kiraly} proposes an anonymous communication system based on IPSec: IPPriv.
+It operates in a similar way to Tor, with telescoping circuits and link encryption, but uses IPSec for both.
+Unlike Tor circuit encryption, IPSec adds a header whether or not authentication is enabled.
+Therefore cells must be padded to hide how many layers of encryption is needed, and there is a limit on path length.
+Architecturally, IPPriv is similar to Freedom: IP packets are captured at the initiator and emitted at the exit nodes.
+
+\subsection{Liberatore: 100-tor-spec-udp}
+
+\begin{figure}
+\includegraphics[scale=0.7]{liberatore-data}
+\caption{\label{fig:liberatore-data}The Liberatore scheme is largely the same as Tor, except that data is received over UDP SOCKS rather than TCP SOCKS, transported over DTLS/UDP rather than TLS/TCP, and emitted as UDP rather than TCP. To handle the lack of in-order delivery, the Circuit cryptography is changed to have an explicit rather than implicit sequence number, and Cell Auth authenticates cells on the basis of the hash of a single cell rather than a running hash over all cells received in the circuit so far.}
+\end{figure}
+
+Liberatore~\cite{liberatore} proposes a design (shown in \prettyref{fig:liberatore-data}) for the transport of UDP over Tor, but which does not offer in-order reliable delivery, so therefore cannot be used for TCP.
+It is intended to work in parallel to the existing TCP variant of Tor, and all control traffic is sent over the existing TLS/TCP connections between nodes; only UDP payload cells are sent over the DTLS/UDP links.
+
+\section{Transport protocols}
+
+The transport protocol is used, at a minimum for meeting the in-order reliable transport properties expected by applications to be provided by TCP.
+
+\subsection{Kernel-mode TCP}
+
+One option for a transport protocol is to use the kernel TCP stack as a transport protocol.
+When TCP sessions are end to end, this introduces a serious anonymity vulnerability as the host operating system could be fingerprinted (if TCP sessions are hop by hop, as in Reardon's proposal, this would not be an issue).
+There are also other challenges of using the kernel-mode TCP stack.
+Firstly, special operating system access would be needed to intercept packets from virtual network interfaces.
+Secondly, Tor would be unable to have low level control over the TCP congestion control algorithms.
+
+\subsection{User-mode TCP}
+
+Reardon uses the Daytona TCP stack, which has the difficulty of not being publicly available and under a license incompatible with Tor's
+There have been initial attempts to port the FreeBSD TCP stack to user-space, but these are not yet mature.
+In any case, Tor will be the primary user of any user-mode TCP stack for the foreseeable future, which could come with significant maintenance costs.
+
+\subsection{User-mode SCTP}
+
+When reliability is initiator-to-exit, or hop-by-hop, there is no need to use TCP.
+An alternative transport protocol is SCTP, which offers similar functionality to TCP, but with some extra features.
+There have been proposals to port the FreeBSD SCTP stack to user-space, and this would be a potential candidate for use in Tor, but the same arguments for user-mode TCP apply to SCTP.
+
+\subsection{$\upmu$TP}
+
+$\upmu$TP is a reliable in-order transport protocol using the LEDBAT (Low Extra Delay Background Transport) congestion avoidance algorithm, so as the achieve the following goals:
+\begin{itemize}
+\item Use all available bandwidth on a link
+\item Add little latency
+\item Yield to TCP flows using the same bottleneck link
+\end{itemize}
+
+Its major advantage over other user-space alternatives is that it is implemented in libutp\footnote{\url{https://github.com/bittorrent/libutp/}}, and this implementation has seen wide usage.
+Therefore if Tor were to adopt this library, we would not be entirely responsible for maintenance, and we have reasonable expectation that there would not be blocking bugs.
+However, $\upmu$TP is designed to yield to TCP, whereas Tor will likely aim to be TCP-friendly but not necessarily yield to it.
+Also, $\upmu$TP does not have an explicit method to preserve fairness between flows sharing the same link -- one of the main goals of a transport protocol for Tor.
+Nevertheless, it may be possible to tweak the parameters of libutp to be more suitable for Tor.
+
+\subsection{CurveCP}
+
+CurveCP is a transport protocol offering congestion management and reliable in-order delivery.
+It also implements mandatory encryption and authentication.
+While both of these are required, they are not suitable for use within datagram-Tor directly.
+Firstly, hop-by-hop encryption and authentication may need to be performed without reliable in-order delivery.
+Secondly, the circuit encryption must be done without increasing length but CurveCP increases message lengths to accommodate the authentication tag.
+
+Even so, it would be possible to use CurveCP as the transport protocol, and accept the inefficiency of encrypting data which is already encrypted.
+End-to-end authentication is desirable, so this feature would be of use although it would be inefficient to use the CurveCP handshake protocol when the two ends already share a key.
+
+Alternatively, CurveCP could be refactored to separate out the congestion control and reliable in-order delivery and use this as an end-to-end transport protocol.
+Also, the encryption and authentication could be used for hop-to-hop links, but with reliable in-order delivery disabled.
+
+A user-mode implementation for CurveCP is available\footnote{See \texttt{curvecp/} in \url{http://hyperelliptic.org/nacl/nacl-20110221.tar.bz2}}, but does not include an explicit copyright statement.
+However related software from the author (Curve25519) was released into the public domain, so it is likely that CurveCP will also be.
+
+\section{Design decisions to be made}
+
+\subsection{Reliability and congestion control end-points and granularity}
+
+A variety of options are available for the end-points for reliability and congestion control protocols.
+In Tor, TCP is used for both reliability and congestion control, on a hop-by-hop basis, with link level granularity.
+In Reardon's proposal, TCP is still hop-by-hop, but at circuit level granularity.
+With Viecco's proposal, TCP is initiator-to-exit, at stream level.
+Finally, Freedom, IPPriv, and Cebolla all have TCP initiator-to-server.
+
+An advantage of initiator-to-exit/server reliability is that intermediate nodes may drop cells when load is high, and rely on congestion control to reduce the data rate.
+In contrast, with hop-by-hop reliability, once a cell has been acknowledged, it may not be dropped.
+However, circuit level cryptography is made easier and more efficient if it can assume reliability from the underlying transport.
+
+A risk of initiator-to-exit/server reliability is that the characteristics of the reliability protocol are exposed to nodes other than those which the initiator directly connects to.
+This raises the possibility of fingerprinting, especially if the initiator's host networking stack is used.
+
+Link level granularity should in principle have lower overhead, but has the disadvantage that lost cells from one circuit will cause unnecessary delay on other circuits.
+Circuit level granularity, as proposed by Reardon, removes this problem and thus decreases latency when there is packet loss.
+Stream level granularity requires initiator-to-exit/server reliability as the stream level is only exposed to the exit node and server, but in principle should reduce unnecessary delay even more.
+
+Of course it is not necessary for reliability and congestion control to be linked, but existing transport protocols offer both.
+Tor currently uses TCP for link level congestion control, but uses a custom algorithm for circuit and stream level.
+Unless stream level granularity is used for the transport-protocol-provided congestion control, it is likely that some other congestion control algorithm will be needed to preserve fairness between different streams on a circuit.
+
+\subsection{First-hop protocol}
+
+The primary reason to use a datagram transport is to reduce congestion within the core network.
+Therefore, it is not essential to use datagram transport for the connection from initiator to first-hop.
+Bridge users, who desire censorship-resistance may therefore wish to continuing using TLS over TCP, rather than datagrams.
+This will be relatively simple to accommodate with hop-to-hop reliability.
+However, with initiator to exit/server reliability, either there would need to be TCP within TCP (and the consequential performance impact), or the bridge node would need to be the TCP end point, rather than initiator.
+
+It may however be desirable to use a datagram transport for the first-hop when used in conjunction with pluggable transports.
+This is because the pluggable transport would not need to provide reliability and so could run over UDP with little difficulty (\eg disguising traffic as VoIP).
+Even with TCP-based pluggable transports, switching to datagram transport for the first hop could be useful.
+For example, while HTTP runs over TCP, it does not provide in-order reliable transport when multiple connections would be used (as is the case for any realistic implementation).
+
+\subsection{Migration path}
+
+Clearly it is essential that there be a smooth transition between the existing TCP transport and datagram transport.
+It is also necessary that the initial users of datagram transports are sufficiently numerous so as not to be deanonymized.
+It would also be desirable to make maximum usage of nodes which have been upgraded to support datagram transports.
+
+Therefore, Tor would have to support both TCP and datagram transports until a sufficient proportion of the network has upgraded.
+If TCP is still used for first-hop connections, Tor nodes would have to support TCP for the foreseeable future.
+
+With hop-by-hop reliability, it would be possible to use datagram transports for segments of a circuit where a pair of nodes support datagram transports.
+In contrast, with initiator-to-exit/server reliability, all hops for a circuit would need to support datagram transports for a circuit to use datagram transports.
+This means that more circuits would able to, at least partially, use datagram transports for hop-by-hop reliability.
+
+So as to preserve the anonymity set of datagram transport users, clients should not use datagram transports until a sufficient number of other clients support them.
+This could be achieved by having a flag in the consensus which states whether datagram transports should be used.
+This flag would only be set once enough of the network supports datagram transports, on the assumption that clients upgrade roughly as frequently as nodes.
+
+The need for collective action is less severe for hop-by-hop reliability because the datagram transport is only visible on a hop-by-hop basis.
+However, it should be assumed that whether a circuit is using hop-by-hop reliability will be visible to other hops on the circuit based on traffic characteristics.
+For initiator-to-exit/server reliability whether the initiator supports datagram transport will be clearly visible to all hops on the circuit.
+
+\subsection{Transport protocol}
+
+A transport protocol will need to be selected, such as $\upmu$TP, CurveCP, TCP or SCTP (user-mode or kernel-mode).
+
+\subsection{Hop-to-hop encryption and authenticity}
+
+For all schemes considered, hop-by-hop encryption is required to hide which packet belongs to which circuit; authenticity is also highly desirable.
+Currently Tor uses TLS, but this requires a reliable link layer, which is likely to be eliminated to reduce unnecessary delay in conditions of packet loss.
+The ``natural'' choice would be to use DTLS, as adopted by Reardon, but a custom protocol, such as that adopted by Viecco, is another possibility.
+CurveCP includes a suitable link layer encryption, but the implementation tightly couples the encryption/authentication layer with the reliability and congestion control.
+
+\subsection{Socket usage}
+
+One current limiting factor for Tor nodes running on Windows is limitations on number of sockets.
+%TODO: Is this fixed by iocp?
+All the proposed datagram schemes with user-space reliability protocols reduce socket usage on intermediate nodes, which may be beneficial if the IOCP functionality in libevent does not completely solve this issue.
+However high socket usage is potentially still an issue on exit nodes, except for those proposals which use initiator-to-server reliability.
+
+\subsection{Circuit encryption and cell authentication}
+
+Tor's current circuit encryption scheme is AES CTR mode without explicit IVs.
+This approach depends on a reliable in-order transport so where reliability is above circuit encryption in the protocol stack (as it is with initiator-to-exit/server reliability), a different approach would be needed.
+The most obvious way of extending circuit encryption would be to include an IV in every cell, which would increase the protocol overhead but allow cells to be dropped or re-ordered without affecting the decryption of others.
+For hop-by-hop reliability, circuit encryption is above reliability and so no change is needed.
+
+Tor's current cell authentication scheme is to include a running digest over all cells sent on this circuit.
+The digest is only 32 bits, on the basis that a circuit is destroyed if the digest doesn't match and therefore in the event that a cell is not detected as corrupted immediately, it is very likely that the following cell will be rejected and the circuit destroyed.
+
+Calculating a running digest is possible with hop-by-hop reliability so there need be no change to cell authentication for this approach.
+However with Liberatore's and Viecco's approach, cell authentication is performed at a lower layer in the protocol stack than any reliability protocol and so a running digest is no longer suitable.
+Therefore a cell digest could be used, but to give similar security guarantees, the digest length would need to be extended.
+
+Tor does not guarantee authenticity of cells, mainly because this would require a non-length-preserving cell encryption and thus limit path lengths and require padding to hide how many layers of encryption are in place.
+The path length limit is no longer an issue because there are other methods in place for Tor to limit path length, however padding may still be undesirable for efficiency reasons.
+Tor's lack of cell authenticity permits tagging attacks, but this is explicitly permitted by the Tor threat model.
+If this is considered a problem, an approach like Kiraly's, which includes hop-by-hop cell authentication, could be adopted.
+
+\subsection{Carrying UDP traffic}
+
+The primary motivation for Tor datagram transports is to improve the performance of TCP over Tor.
+However, it may also be desirable to allow UDP to be sent over Tor, for example VoIP traffic.
+All the schemes which use initiator-to-server reliability will naturally support UDP, as Tor would not need to even know the protocol type of packets.
+Liberatore's proposal is explicitly designed to support UDP, although UDP packets will not be indistinguishable from TCP packets because they are inside different link-layer encapsulations.
+Viecco's proposal could be easily extended to transport UDP, if the SOCKS server on the exit node were extended to support UDP.
+Reardon's proposal is more challenging to support UDP because reliability is ensured at the circuit layer and so any dropped cells will be re-transmitted, which will defeat the purpose of the application using UDP in the first place.
+Circuits could be marked as not needing reliability, but a different circuit encryption and cell authentication scheme would need to be used for these; also such circuits would be distinguishable from TCP circuits by intermediate nodes.
+
+\subsection{Carrying ACK messages}
+
+ACK messages needed for reliability and congestion control may need to be treated specially because they are much shorter than data packets.
+It would be possible to pad them to the same size as data packets, but this may be inefficient.
+With hop-by-hop reliability, ACK packets would be encrypted using DTLS which only adds a small amount of padding, so an external adversary would likely be able to tell which packets are ACK messages and thus learn something about the circuits being carried.
+With initiator-to-server/exit reliability the situation is more problematic as now information on traffic characteristics would be more visible to middle nodes.
+
+\paragraph{Unreliable control messages}
+
+Viecco proposes that control messages should not be carried in a reliable transport.
+A transport session is set up only between Initiator and Exit and only used for carrying data.
+This is best option in terms of minimizing state on intermediate Tor nodes, and is the closest to the standard Internet router model.
+It also reduces the overhead of setting up transport streams for carrying control messages.
+However it is complex from a protocol-design perspective as all participants must assume that any control message may be dropped at any point and arbitrarily re-ordered.
+In principle control messages may be corrupted too, but the hop-by-hop integrity protocol should prevent this from happening.
+
+\section{Recommendations and future study}
+
+This section proposes a set of provisional recommendations and raises questions which should be answered in further analysis.
+
+\subsection{Architecture}
+
+The most fundamental question to be resolved is the overall architecture: hop-by-hop reliability (\eg Reardon), initiator-to-exit reliability (\eg Viecco) or initiator-to-server reliability (\eg Freedom).
+There are arguments for each approach, but in the absence of conclusive performance results, one approach is to guide the architecture by engineering and deployment difficulties.
+Initiator-to-server reliability would require low-level access on exit nodes, so as to generate raw packets, which could put pressure on the already scarce resource of exit bandwidth.
+Initiator-to-exit has the problem that the cryptographic protocols would need to be modified to handle the lack of reliable in-order delivery of cells.
+In comparison, this makes hop-by-hop reliability (\eg Reardon) the most promising approach.
+
+\subsection{Transport protocol}
+
+No single candidate for transport protocol is the obvious choice.
+The anonymity and engineering difficulties with using the kernel-mode TCP stack suggest that this approach is not suitable, except perhaps for experimentation.
+User-mode TCP or SCTP stacks are possible, but are not yet available in a usable form.
+$\upmu$TP and CurveCP are readily available, but $\upmu$TP would be the easiest to integrate and so is a good choice for testing.
+Further study is needed as to whether investing engineering time in user-mode TCP or SCTP is a good choice, compared to analyzing and tuning $\upmu$TP so that it has the properties required.
+
+\subsection{Other trade offs}
+
+A consequence of adoption hop-by-hop reliability is that Tor would remain able only to carry TCP traffic.
+This may be the prudent engineering choice, so as to avoid having to change many aspects of Tor at the same time.
+Nevertheless, if VoIP and similar protocols are strongly desirable, it may be worth revisiting this decision.
