+# 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.

+#     - 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):

+# BSD SED NOTES

+# BSD SED is not very nice compared to GNU sed, but it is the most

+# 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.

+#	* There was a LaTeX error
+#	* A needed file was not found

+#	Flatten the .aux file into another file
+#	Add source 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

+# 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-tex:
+#        Remove all files generated from LaTeX invocations except dependency
+#        information.  Leaves graphics alone.
+#
+#    clean-deps:
+#        Removes all auto-generated dependency information.
+#
+#    clean-auxiliary:
+#        Removes extra files created by various targets (like the dependency
+#        graph output).
+#
+#    clean-nographics:
+#        Cleans everything *except* the graphics files.
+#
+#    help:

+#
+#    _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

+#        of the environment-overridable VIEW_POSTSCRIPT variable (currently set
+#        to $(VIEW_POSTSCRIPT)).  The postscript viewer is used because it

+#    _all_stems:
+#        Print a list of stems.  These represent bare targets that can be

+#
+#    _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

+#
+#    _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

+#       .jpg      : jpeg (goes through ImageMagick)
+#       .eps.gz : gzipped eps
+#
+#       The behavior of this makefile with each type is described in

+#
+#    %.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.
+#
+#       literate Haskell: %.lhs
+#
+#           Runs the lhs2tex program to generate a .tex file.
+#
+#    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.
