+# 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):
+# * Bumped version to 2.1.41
+# * issue 60: bad makeindex runs now error out on subsequent tries
+# Chris Monson (2009-12-01):

+# * issue 36: build all indices (for e.g., splitidx usage)

+# Chris Monson (2009-11-23):
+# * Bumped version to 2.1.39

+#     line preceding the first error.
+# * Issue 51: remove head.tmp and body.tmp in make clean invocation
+# * Issue 56: maintain multiple versions of log files (for debugging)

+#     dvi, pdf, and ps if it exists
+# Chris Monson (2009-09-25):
+# * Bumped version to 2.1.32
+# * Fixed so that a changed lol file will cause a rebuild

+# Chris Monson (2009-05-15):
+# * Bumped version to 2.1.26
+# * Included patch for issue 9 from favonia - detects .fig changes for

+# Chris Monson (2009-03-27):

+#     settable from Makefile.ini
+# * 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

+# Chris Monson (2009-03-09):
+# * Bumped version to 2.1.24
+# * issue 27: xmgrace support (thanks to rolandschulzhd)

+#     files that should *not* be considered includes.  Thanks to Holger
+#     <yllohy@googlemail.com> for this patch.

+#     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

+# 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.

+#	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

+# 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:
+#        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.
+#
+#       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.

-\section*{Introduction}
-This document serves to summarise \XeTeX's additional features without being so much as a `users' guide'. Note that much of the functionality addressed here is provided in abstracted form in various \LaTeX\ packages and Con\TeX{}t modules.
-
-The descriptions here should be a fairly exhaustive list of the new primitives and features of \XeTeX. Descriptions are still a little aenemic, however. I don't have much time to maintain this document, so contributions are highly welcomed \verb|:)|

-\section{The \cs{font} command}
-The |\font| command has seen significant addition in \XeTeX\ to facilitate extended font feature selection. Under \TeX, fonts were selected like so: |\font\1="|\xarg{tfm name}|"| with various options appended such as `|at 10pt|' or `|scaled 1.2|', with obvious meaning. This syntax still works, but it has been greatly extended in \XeTeX.
-
-The extended syntax looks something like\par
-{\centering|\font\1="|\xarg{font identifier}\xarg{font options}|:|\xarg{font features}|"| \xarg{\TeX\ font features}\par}\noindent
-The \xarg{font identifier} is the only mandatory part of the above syntax.  It is either a declared name of a font (e.g., `|Latin Modern Roman|') or a font file name in square brackets (e.g., |[lmroman10-regular]|).
-
-When using a font name, the font is looked up through the operating system, using (except on Mac~OS~X) the |fontconfig| library.  Running |fc-list| should show you the font names available.  \Eg,
-|\font\1="Liberation Serif"| \hfill \emph{look for OS-installed font}
-
-When using a file name, the |xdvipdfmx| driver must be used (this is the default), and the file name must be surrounded with square brackets. The current directory and the |texmf| trees are searched for files matching the name, or the path may be embedded in the
-font declaration, as usual with |kpathsea|. \Eg,
-\begin{quote}\small
-|\font\2="[lmroman10-regular]"| \hfill {\em find |lmroman10-regular.otf| in any tree}
-|\font\3="[/myfonts/fp9r8a]"| \hfill {\em look for |fp9r8a| only in |/myfonts/|}
-\end{quote}
-
-A file with either an |.otf| or |.ttf| extension will be found.  The extension can also be specified explicitly.
-
-(Aside: if you load |luaotfload.sty|, you can use this same syntax in Lua\TeX, which doesn't provide \TeX-layer syntax by default.  The |luaotfload| package works in plain \TeX\ and \LaTeX.)
-
-
-\subsection{Font options}
-
-\xarg{Font options} are only applicable when the font is selected through the operating system (\ie, without square brackets).  They may be any concatenation of the following: 
-
-\begin{optdesc}
-\item[/B] Use the bold version of the selected font.
-\item[/I] Use the italic version of the selected font.
-\item[/BI] Use the bold italic version of the selected font.
-\item[/IB] Same as \texttt{/BI}.
-\item[/S=$x$] Use the version of the selected font corresponding to the optical size $x$\,pt.
-\item[/AAT] Explicitly use the ATSUI renderer (Mac~OS~X only).
-\item[/ICU] Explicitly use the ICU OpenType renderer.
-\item[/GR] Explicitly use the Graphite font\footnote{\url{http://scripts.sil.org/RenderingGraphite}} renderer.
-\end{optdesc}
-
-\subsection{Font features}
-
-The \xarg{font features} is a comma or semi-colon separated list activating or deactivating various OpenType, Graphite, or AAT font features, which will vary by font. 
-The \XeTeX\ documentation files \path{aat-info.tex} and \path{opentype-info.tex} provide per-font lists of supported features.
-
-\subsubsection{Arbitrary OpenType, Graphite, or AAT features}
-OpenType font features are chosen with \hlink{http://www.microsoft.com/typography/otspec/featuretags.htm}{standard tags}. They may be either comma- or semicolon-separated, and prepended with a |+| to turn them on and a |-| to turn them off.
-\begin{example}
-\font\liber="Linux Libertine O/I=5:+smcp" at 12pt
-\liber This is the OpenType font Linux Libertine in italic with small caps.
-\end{example}
-
-Varying depending on the language and script in use (see \secref[vref]{script}), a small number of OpenType features, if they exist, will be activated by default.
-
-AAT font features and Graphite font features are specified by strings within each font rather than standardised tags. Therefore, even equivalent features between different fonts can have different names.
-\begin{example}
-\font\gra="Charis SIL/GR:Small Caps=True" at 12pt
-\gra This is the Graphite font Charis SIL with small caps.
-\end{example}
-
-\subsubsection{Options for all fonts}
-Some font features may be applied for any font. These are
-\begin{optdesc}
-\item[mapping=\textsl{<font map>}] 
-Uses the specified font mapping for this font. This uses the TECKit engine to transform unicode characters in the last-minute processing stage of the source. For example, |mapping=tex-text| will enable the classical mappings from ugly ascii |``---''| to proper typographical glyphs ``---'', and so on.
-
-\item[color={\slshape RRGGBB}{[{\slshape TT}]}] 
-Triple pair of hex values to specify the colour in RGB space, with an optional value for the transparency. 
-
-\item[letterspace=$x$] 
-Adds $x/S$ space between letters in words, where $S$ is the font size.
-
-\item[embolden=$x$]
-Increase the envelope of each glyph by the set amount (this makes the letters look `more bold'). $x=0$ corresponds to no change; $x=1.5$ is a good default value.
-
-\item[extend=$x$]
-Stretch each glyph horizontally by a factor of $x$ (i.e., $x=1$ corresponds to no change).
-
-\item[slant=$x$]
-Slant each glyph by the set amount. $x=0$ corresponds to no change; $x=0.2$ is a good default value. The slant is given by $x=R/S$ where $R$ is the displacement of the top edge of each glyph and $S$ is the point size.

-\section{Character classes}
-
-The idea behind character classes is to define a boundary where tokens can be added to the input stream without explicit markup. It was originally intended to add glue around punctuation to effect correct Japanese typesetting. This feature can also be used to adjust space around punctuation for European traditions. The general nature of this feature, however, lends it to several other useful applications including automatic font switching when small amounts of another language (in another script) is present in the text.

Class 1 is for CJK ideographs, classes 2 and 3 are CJK punctuation. The boundary of a text string is considered class 255, wherever there is a boundary between a `run' of characters and something else --- glue, kern, math, box, etc. Special case class 256 is ignored; useful for diacritics so I'm told.}

-\desc{Insert (pages of) a \PDF{}. See below for explanation of optional arguments.}
-\endcmd
-
-\noindent
-In the graphic/\PDF{} commands above,
-\xarg{filename} is the usual file name argument of \cs{input}, \cs{openin}, \etc.
-It must not terminated by \cs{relax} if options are given.  
-\xarg{int} and \xarg{dimen} are the usual integer or dimen specifications
-of regular \TeX.
-
-The rotation is specified in degrees (\ie, an input of `|360|' is full circle)  
-and the rotation is counterclockwise. The syntax of \xarg{decimal}
-require some explanation:
-\begin{quote}
-\<decimal> $\to$ \<optional signs>\<unsigned decimal>\\
-\<unsigned decimal> $\to$ \<normal decimal> \| \<coerced dimen> \| \<internal dimen>\\
-\<normal decimal> -> \<normal integer> \| \<decimal constant>
-\end{quote}
-A \xarg{coerced dimen} or \xarg{internal dimen} is interpreted as number with  
-unit `|pt|'. For example, for a rotation specified with a dimension \cs{testdim},
-\begin{itemize}
-\item \verb|\testdim=45pt  | results in a rotation of 45\textdegree,
-\item \verb|\testdim=1in    | is 72.27\textdegree, and
-\item \verb|\testdim=100sp| is (100/65536)\textdegree.
-\end{itemize}
-In all cases the resulting decimal number for rotation $x$ must be  
-within limits $-16384 < x < 16384$.
-
-The \cs{XeTeXpdffile} command takes one more optional argument for specifying to which `box' the \PDF{} should be cropped before inserting it (the second optional argument listed in thes syntax of \cs{XeTeXpdffile} above). The \PDF{} standard defines a number of (rectangular) bounding boxes that may be specified for various purposes. These are described in the \PDF{} Standard\footnote{Adobe Systems Incorporated, 2008:\\ \url{http://www.adobe.com/devnet/acrobat/pdfs/PDF32000_2008.pdf}} and summarised below.
-\begin{quote}
-\begin{description}
-\item[media] the box defining the physical page size.
-\item [crop] the box of the page contents for display/printing purposes.
-\item [bleed] the box containing the page contents plus whatever extra space required for printing purposes.
-\item [trim] the box of the finished page after trimming the printed `bleed box'.
-\item [art] the box containing the `meaningful content' of the page. This could be the crop box with boilerplate text/logos trimmed off.
-\end{description}
-\end{quote}
-When not specified in the \PDF{} to be inserted, the crop box defaults to the media box, and the bleed, trim, and art boxes default to the crop box.

+\section*{Introduction}
+
+This document serves to summarise additional features of \xetex without
+being so much as a ‘users’ guide. Note that much of the functionality
+addressed here is provided in abstracted form in various \latex
+packages and \context modules.
+
+The descriptions here should be a fairly exhaustive list of the new
+primitives and features of \xetex. Descriptions are still a little
+aenemic, however.

+\part{\xetex specifics}
+
+\section{The \cs{font} command}
+
+Traditionally, fonts were selected in \tex like this:
+|\font\1=|\xarg{tfm name} with various options possibly appended
+% harder to read without the extra space
+such as \ ‘| at 10pt|’ \ or \ ‘| scaled 1.2|’, with obvious meaning. This syntax
+still works, but it has been greatly extended in \xetex.
+
+The extended syntax looks schematically like this:
+
+{\centering
+ |\font\1="|\xarg{font identifier}\xarg{font options}|:|\xarg{font features}|"|
+ \xarg{\tex font options}\par}
+
+\noindent The \xarg{font identifier} is the only mandatory part of the
+above syntax.  If it is given in square brackets, (e.g.,
+|[lmroman10-regular]|), it is taken as a font file name.
+Without brackets, the name is looked up both as a file name and a system
+font name.
+When using a font name, the font is looked up through the operating
+system, using (except on Mac~OS~X) the |fontconfig| library.  Running
+|fc-list| should show you the font names available.  \Eg,
+\begin{quote}\small
+|\font\1="Liberation Serif"| \hfill \emph{look for OS-installed font}
+\end{quote}
+
+Fonts have many internal names, and XeTeX matches them in the following order:
+\vskip1ex
+\begin{itemize}
+  \item Full Name;
+  \item if the name has a hyphen, it is split into Family-Style pair then matched;
+  \item PostScript Name;
+  \item Family Name, if there is more than one match;
+  \begin{itemize}
+    \item look for font with “regular” bit set in OS/2 table, if no match;
+    \item look for font with style “Regular”, “Plain”, “Normal” or “Roman”, in that order.
+  \end{itemize}
+\end{itemize}
+\bigskip
+
+When using a file name, the |xdvipdfmx| driver must be used (this is the
+default). The current directory and the |texmf| trees are searched for
+files matching the name, or the path may be embedded in the font
+declaration, as usual with |kpathsea|. \Eg,
+\begin{quote}\small
+|\font\2="[lmroman10-regular]"| \hfill
+  {\em find |lmroman10-regular.otf| in any tree}
+|\font\3="[/myfonts/fp9r8a]"| \hfill
+  {\em look for |fp9r8a| only in |/myfonts/|}
+\end{quote}
+
+A file with either an |.otf|, |.ttf| or |.pfb| extension (in that order) will be found.  The
+extension can also be specified explicitly.
+If the file is a font collection (e.g., |.ttc| or |.dfont|), the index of the
+font can be specified using a colon followed by zero-based font index inside
+the square brackets. \Eg,
+\begin{quote}\small
+|\font\4="[myfont.ttc:1]"| \hfill {\em load the second font from |myfont.ttc| file}
+\end{quote}
+
+
+\subsection{Font options}
+
+\xarg{Font options} are only applicable when the font is selected
+through the operating system (\ie, without square brackets).  They may
+be any concatenation of the following:
+
+\begin{optdesc}
+\item[/B] Use the bold version of the selected font.
+\item[/I] Use the italic version of the selected font.
+\item[/BI] Use the bold italic version of the selected font.
+\item[/IB] Same as \texttt{/BI}.
+\item[/S=$x$] Use the version of the selected font corresponding to the
+optical size $x$\,pt.
+\item[/AAT] Explicitly use the AAT renderer (Mac~OS~X only).
+\item[/OT] Explicitly use the OpenType renderer (new in 0.9999).
+\item[/GR] Explicitly use the Graphite renderer.%
+           \footnote{\url{http://scripts.sil.org/cms/scripts/page.php?site_id=projects&item_id=graphite_home}}
+\item[/ICU] Explicitly use the OpenType renderer (deprecated since 0.9999).
+\end{optdesc}
+
+
+\subsection{Font features}
+
+The \xarg{font features} is a comma or semi-colon separated list
+activating or deactivating various OpenType, Graphite, or AAT font
+features, which will vary by font.  In contrast to font options,
+features work whether the font is selected by file name or through the
+operating system.
+
+The \xetex documentation files \path{aat-info.tex} and
+\path{opentype-info.tex} provide per-font lists of supported features.
+
+\subsubsection{Arbitrary OpenType, Graphite, or AAT features}
+
+OpenType font features are chosen with
+\hlink{http://www.microsoft.com/typography/otspec/featuretags.htm}{standard
+tags}. They may be either comma- or semicolon-separated, and prefixed
+with a |+| to turn them on and a |-| to turn them off, optionally followed
+by |=| and a 0-based index for selecting alternates from multiple
+alternates features (ignored for |-| prefixed tags).
+
+\begin{example}
+\font\liber="Linux Libertine O/I=5:+smcp" at 12pt
+\liber This is the OpenType font Linux Libertine in italic with small caps.
+\end{example}
+
+Varying depending on the language and script in use (see
+\secref[vref]{script}), a small number of OpenType features, if they
+exist, will be activated by default.
+
+\begin{example}
+\font\antt="Antykwa Torunska"         at 12pt \antt 0
+\font\antt="Antykwa Torunska:+aalt=0" at 12pt \antt 0
+\font\antt="Antykwa Torunska:+aalt=1" at 12pt \antt 0
+\font\antt="Antykwa Torunska:+aalt=2" at 12pt \antt 0
+\font\antt="Antykwa Torunska:+aalt=3" at 12pt \antt 0
+\font\antt="Antykwa Torunska:+aalt=4" at 12pt \antt 0
+\end{example}
+
+AAT font features and Graphite font features are specified by strings
+within each font rather than standardised tags. Therefore, even
+equivalent features between different fonts can have different names.
+
+\begin{example}
+\font\gra="Charis SIL/GR:Small Caps=True" at 12pt
+\gra This is the Graphite font Charis SIL with small caps.
+\end{example}
+
+\subsubsection{Options for all fonts}
+
+Some font features may be applied for any font. These are
+\begin{optdesc}
+\item[mapping=\textsl{<font map>}] 
+Uses the specified font mapping for this font. This uses the TECKit
+engine to transform unicode characters in the last-minute processing
+stage of the source. For example, |mapping=tex-text| will enable the
+classical mappings from ugly ascii |``---''| to proper typographical
+glyphs “—”, and so on.
+
+\item[color={\slshape RRGGBB}{[{\slshape TT}]}] 
+Triple pair of hex values to specify the colour in RGB space, with an
+optional value for the transparency.
+
+\item[letterspace=$x$] 
+Adds $x/S$ space between letters in words, where $S$ is the font size.
+
+\item[embolden=$x$]
+Increase the envelope of each glyph by the set amount (this makes the
+letters look ‘more bold’). $x=0$ corresponds to no change; $x=1.5$ is a
+good default value.
+
+\item[extend=$x$]
+Stretch each glyph horizontally by a factor of $x$ (i.e., $x=1$
+corresponds to no change).
+
+\item[slant=$x$]
+Slant each glyph by the set amount. $x=0$ corresponds to no change;
+$x=0.2$ is a good default value. The slant is given by $x=R/S$ where $R$
+is the displacement of the top edge of each glyph and $S$ is the point
+size.
+
+\end{optdesc}
+
+\subsubsection{OpenType script and language support}\seclabel{script}
+
+OpenType font features (and font behaviour) can vary by
+\hlink{http://www.microsoft.com/typography/otspec/scripttags.htm}{script}
+(‘alphabet’) and by
+\hlink{http://www.microsoft.com/typography/otspec/languagetags.htm}{language}.
+These are selected with four and three letter tags, respectively.
+
+\begin{optdesc}
+\item[script=\textsl{<script tag>}] Selects the font script.
+\item[language=\textsl{<lang tag>}] Selects the font language.
+\end{optdesc}
+
+\subsubsection{Multiple Master and Variable Axes AAT font support}
+
+\begin{optdesc}
+\item[weight=$x$] Selects the normalised font weight, $x$.
+\item[width=$x$] Selects the normalised font width, $x$.
+\item[optical size=$x$] Selects the optical size, $x$\,pt. Note the
+difference between the \texttt{/S} font option, which selects discrete
+fonts.
+\end{optdesc}
+
+\subsubsection{Vertical typesetting}
+\begin{optdesc}
+\item[vertical] 
+Enables glyph rotation in the output so vertical typesetting can be performed.
+\end{optdesc}
+
+\part{New commands}
+
+\section{Font primitives}
+
+\cmd|\XeTeXtracingfonts|
+\desc{If nonzero, reports where fonts are found in the log file.}
+\endcmd
+
+\cmd|\XeTeXfonttype|
+\xarg{font}
+\desc{
+  Expands to a number corresponding to which renderer is used for a
+  \xarg{font}:
+  \begin{optdesc}
+    \item [0] for \tex (a legacy TFM-based font);
+    \item [1] for AAT;
+    \item [2] for OpenType;
+    \item [3] for Graphite.
+  \end{optdesc}
+}

+\end{example}

+\cmd|\XeTeXglyph|
+\xarg{glyph slot}

+\endcmd
+
+\cmd|\XeTeXglyphindex|
+|"|\xarg{glyph name}|"| \xarg{space} \emph{or} \cs{relax}
+\desc{Expands to the glyph slot corresponding to the (possibly

+\endcmd
+
+\cmd|\XeTeXcharglyph|
+\xarg{char code} 
+\desc{Expands to the default glyph number of character \xarg{char code}
+in the current font, or 0 if the character is not available in the

+\endcmd
+
+\begin{example}
+\font\1="Charis SIL"\1
+The glyph slot in Charis SIL for the Yen symbol is:
+    \the\XeTeXglyphindex"yen" . % the font-specific glyph name
+Or: \the\XeTeXcharglyph"00A5.   % the unicode character slot
+
+This glyph may be typeset with the font-specific glyph slot:
+\XeTeXglyph150, 
+or the unicode character slot:
+\char"00A5.
+\end{example}
+
+\cmd|\XeTeXglyphbounds|
+\xarg{edge} \xarg{glyph slot}
+\desc{Expands to a dimension corresponding to one of the bounds of a
+glyph, where \xarg{edge} is an integer from 1 to~4 indicating the
+left/top/right/bottom edge respectively, and \xarg{glyph slot} is an
+integer glyph index in the current font (only valid for non TFM-based
+fonts).
+
+The left and right measurements are the glyph sidebearings, measured
+‘inwards’ from the origin and advance respectively, so for a glyph that
+fits completely within its ‘cell’ they will both be positive; for a
+glyph that ‘overhangs’ to the left or right, they will be negative. The
+actual width of the glyph’s bounding box, therefore, is the character
+width (advance) minus both these sidebearings.
+
+The top and bottom measurements are measured from the baseline, like
+\tex’s height and depth; the height of the bounding box is the sum of
+these two dimensions.}

+\section{Character classes}
+
+The idea behind character classes is to define a boundary where tokens
+can be added to the input stream without explicit markup. It was
+originally intended to add glue around punctuation to effect correct
+Japanese typesetting. This feature can also be used to adjust space
+around punctuation for European traditions. The general nature of this
+feature, however, lends it to several other useful applications
+including automatic font switching when small amounts of another
+language (in another script) is present in the text.
+
+\cmd|\XeTeXinterchartokenstate|
+\desc{Counter. If positive, enables the character classes functionality.}

+\desc{Assigns a class corresponding to \xarg{interchar class} (range
+0–255) to a \xarg{char slot}. Most characters are class 0 by
+default. Class 1 is for CJK ideographs, classes 2 and 3 are CJK
+punctuation. The boundary of a text string is considered class 255,
+wherever there is a boundary between a ‘run’ of characters and something
+else — glue, kern, math, box, etc. Special case class 256 is ignored;
+useful for diacritics so I’m told.}

+  rotated \xarg{decimal}}
+\desc{Insert (pages of) a PDF. See below for explanation of optional
+arguments.}
+\endcmd
+
+\noindent In the graphic/PDF commands above, \xarg{filename} is the
+usual file name argument of \cs{input}, \cs{openin}, \etc.  It must not
+terminated by \cs{relax} if options are given.  \xarg{int} and
+\xarg{dimen} are the usual integer or dimen specifications of regular
+\tex.
+
+The rotation is specified in degrees (\ie, an input of ‘|360|’ is full
+circle) and the rotation is counterclockwise. The syntax of
+\xarg{decimal} require some explanation:
+\begin{quote}
+\<decimal> $\to$ \<optional signs>\<unsigned decimal>\\
+\<unsigned decimal> $\to$ \<normal decimal>
+  \| \<coerced dimen> \| \<internal dimen>\\
+\<normal decimal> $\to$ \<normal integer> \| \<decimal constant>
+\end{quote}
+A \xarg{coerced dimen} or \xarg{internal dimen} is interpreted as number
+with unit ‘|pt|’. For example, for a rotation specified with a dimension
+\cs{testdim},
+\begin{itemize}
+\item \verb|\testdim=45pt  | results in a rotation of 45\textdegree,
+\item \verb|\testdim=1in    | is 72.27\textdegree, and
+\item \verb|\testdim=100sp| is (100/65536)\textdegree.
+\end{itemize}
+In all cases the resulting decimal number for rotation $x$ must be  
+within the limits $-16384 < x < 16384$.
+
+The \cs{XeTeXpdffile} command takes one more optional argument for
+specifying to which ‘box’ the PDF should be cropped before inserting
+it (the second optional argument listed in thes syntax of
+\cs{XeTeXpdffile} above). The PDF standard defines a number of
+(rectangular) bounding boxes that may be specified for various
+purposes. These are described in the PDF Standard\footnote{Adobe
+Systems Incorporated, 2008:\\
+\url{http://www.adobe.com/devnet/acrobat/pdfs/PDF32000_2008.pdf}} and
+summarised below.
+\begin{quote}
+\begin{description}[style=nextline,leftmargin=1.5cm]
+\item [media] the box defining the physical page size.
+\item [crop] the box of the page contents for display/printing purposes.
+\item [bleed] the box containing the page contents plus whatever extra
+space required for printing purposes.
+\item [trim] the box of the finished page after trimming the printed
+‘bleed box’.
+\item [art] the box containing the ‘meaningful content’ of the
+page. This could be the crop box with boilerplate text/logos trimmed
+off.
+\end{description}
+\end{quote}
+When not specified in the PDF to be inserted, the crop box defaults
+to the media box, and the bleed, trim, and art boxes default to the crop
+box.
