+% I still need to hook in some features into the setup
+% macro. I also have to (re)define farsi etc. in ways
+% similar to arab, so that we have dedicated environments.

+\writestatus{loading}{ConTeXt Font Macros / ArabTeX support}
+
+%D At the \NTG\ 10\high{th} anniversary meeting Klaus Lagally
+%D introduced the audience to arabic typesetting, and after
+%D that I knew that some day I really had to look into his
+%D generic package. And then, sort of simultaniously Maarten
+%D Wisse and Imran Ahsan Nyazee asked me if \CONTEXT\ could
+%D support \ARABTEX, a package that provides right to left
+%D typesetting of (several variants of) arab and hebrew.
+%D Having implemented support for chinese a few weeks before,
+%D I could not resist to build in support for arab and hebrew
+%D too. Writing support for languages that don't give me any
+%D cue on how to pronounce their script, is kind of special.
+
+%D This is a beta version, since I still have to take care of some
+%D macros that conflict with existing stuff.

+%D A few years ago at the Holland Festivities, I attended {\em
+%D The Cave}, one of the most impressive combinations of music
+%D and video I know. This composition of Steve Reich (music)
+%D and .. (video) concentrates on the common grounds of arabs
+%D and jews: their ancestor Abram. Listening to the \CDROM's
+%D of {\em The Cave}, provided me the right ambiance for
+%D filling in the details of this module. In {\em The Cave},
+%D interviews, music, and |<|believe it or not|>| rhythmic
+%D typography are the cornerstones. Remembering those big
+%D screens, it strikes me that like music, \TEX\ too is a
+%D perfect instrument to cross cultural and linguistic
+%D borders. So, let's load Hebrew support as well:
+
+\unexpanded\def\sethebrewfont#1%
+ {\setx@skels
+ \newfonttrue
+ \definedfont[Hebrew#1 sa \ARABTEXparameter\s!rscale]}
+
+% \let \setheb \sethebrew
+
+\unexpanded\def\pheb {\sethebrewfont\s!Regular}
+\unexpanded\def\phebbf{\sethebrewfont\s!Bold}
+
+% \startloadingARABTEX
+
+% \ReadFile{hebtex.sty}
+% \ReadFile{apatch.sty}

+\definefontsynonym [HebrewRegular] [hclassic]

+\defineARABTEXalternative

+%D This module (re)implements the \CWEB\ macros as defined in
+%D the file \type{cwebmac.tex}.
+%D
+%D \CWEB\ uses short, often one character long, names for
+%D macros. This is no real problem because no one is supposed
+%D to read and understand the files generated by \CWEB. The
+%D standard macros are meant for \PLAIN\ \TEX\ users. In
+%D \CONTEXT\ and other macro packages however, there is a
+%D potential conflict with format specific or user defined
+%D commands. Furthermore, the \CWEB\ macros implement their own
+%D output routines. When integrating \CWEB\ documents in
+%D another environment, the \CWEB\ specific macros have to be
+%D made local. The first part of this module is dedicated to
+%D this feature.
+%D
+%D Instead of using \type{\def} and \type{\let} for defining
+%D macros, we use:
+%D
+%D \starttyping
+%D \defCEBmacro arguments {meaning}
+%D \letCEBmacro arguments {meaning}
+%D \stoptyping
+%D
+%D \CWEB files contain implicit calls to macros that generate
+%D the table of contents, the lists of sections and the index.
+%D Because we want to be much more flexible, we implemented our
+%D own alternatives, and therefore have to bypass the original
+%D ones. The next macro is used for defining these obsolete
+%D \CWEB\ macros. The dummies take care of arguments.
+%D
+%D \starttyping
+%D \defCEBdummy arguments {meaning}
+%D \stoptyping
+%D
+%D The list of \CWEB\ specific macro names is saved in a
+%D \TOKENLIST. This serves two purposes. First it enables us to
+%D activate the \CWEB\ macros, which are saved under a
+%D different name, second it can be used to temporary restore
+%D the meanings, for instance when the output routine builds
+%D the page.
+
+\newtoks\CWEBmacros
+
+%D Activating and deactivating is done by means of:
+%D
+%D \starttyping
+%D \activateCWEB
+%D \deactivateCWEB
+%D \stoptyping
+%D
+%D Which are implemented as:
+
+\def\activateCWEB%
+ {\let\doCWEB=\activateCWEBmacro
+ \the\CWEBmacros}
+
+\def\deactivateCWEB%
+ {\let\doCWEB=\deactivateCWEBmacro
+ \the\CWEBmacros}
+
+%D The three definition macros append the name of the macro to
+%D the list. The first two macros save the meaning, the last one
+%D assigns \type{{}} to the macro and gobbles original meaning.
+
+\long\def\defCWEBmacro#1%
+ {\appendtoks\doCWEB#1\to\CWEBmacros
+ \setvalue{newCWEB\string#1}}
+
+\long\def\letCWEBmacro#1%
+ {\appendtoks\doCWEB#1\to\CWEBmacros
+ \letvalue{newCWEB\string#1}}
+
+\long\def\defCWEBdummy#1#2#%
+ {\appendtoks\doCWEB#1\to\CWEBmacros
+ \setvalue{newCWEB\string#1}#2{}%
+ \gobbleoneargument}
+
+%D The macro \type{\defCWEBdummy} of course takes care of the
+%D argument. This leaves the two (de|)|activating macros:
+
+\def\CWEBmacro#1%
+ {\getvalue{newCWEB\string#1}}
+
+\def\activateCWEBmacro#1%
+ {\letvalue{oldCWEB\string#1}=#1%
+ \def#1{\CWEBmacro#1}}
+
+\def\deactivateCWEBmacro#1%
+ {\expandafter\let\expandafter#1\expandafter=\csname oldCWEB\string#1\endcsname}
+
+%D I did consider loading the \CWEB\ macros using temporary
+%D substitutes of \type{\def}, \type{\font}, \type{\newbox} etc.
+%D The main problem is that the file contains more than
+%D definitions and taking all kind of assignments into account
+%D too would not make things easier. So I decided to stick to
+%D the method as just described.
+
+%D Now we're ready for the real job. What follows is a partial
+%D adaption of the file \type{cwebmac.tex}, version 3.1, dated
+%D September 1994 and written by Levy and Knuth. When possible
+%D we kept the original meaning, but we've granted ourselves
+%D the freedom to reformat the macro's for readibility.
+%D
+%D We'll only present the macros we actually use. The source
+%D however contains the original implementation.
+
+% standard macros for CWEB listings (in addition to plain.tex)
+% Version 3.1 --- September 1994.
+%
+% \ifx\documentstyle\undefined\else\endinput\fi % LaTeX will use other macros
+%
+% \xdef\fmtversion{\fmtversion+CWEB3.1}
+
+%D \macros{.}{}
+%D
+%D \CWEBquote preserve a way to get the dot accent (all
+%D other accents will still work as usual).
+
+\letCWEBmacro\: = \.
+
+% \parskip = 0pt % no stretch between paragraphs
+% \parindent = 1em % for paragraphs and for the first line of C text
+
+% \font\ninerm = cmr9
+% \let\mc = \ninerm % medium caps
+% \font\eightrm = cmr8
+% \let\sc = \eightrm % small caps (NOT a caps-and-small-caps font)
+% \let\mainfont = \tenrm
+% \let\cmntfont = \tenrm
+% \font\tenss = cmss10
+% \let\cmntfont = \tenss % alternative comment font
+% \font\titlefont = cmr7 scaled \magstep4 % title on the contents page
+% \font\ttitlefont = cmtt10 scaled \magstep2 % typewriter type in title
+% \font\tentex = cmtex10 % TeX extended character set (used in strings)
+% \fontextraspace\tentex = 0pt % no double space after sentences
+
+%D \macros{mc,sc,cmntfont,eightrm}{}
+%D
+%D The naming of the fonts in in line with those in \PLAIN\
+%D \TEX. Although \CONTEXT\ implements its own scheme, there is
+%D still support for the \PLAIN\ ones. We keep the original
+%D names, but change their meaning. That way the macros obey
+%D switching to other sizes or styles.
+
+\defCWEBmacro\mc {\tx}
+\defCWEBmacro\sc {\txx}
+\defCWEBmacro\cmntfont {\ss}
+\defCWEBmacro\eightrm {\tx}
+
+%D \macros{tentex,sevenrm,sevensy,teni}{}
+%D
+%D The next one uses a temporary solution. The \type{cmtex10}
+%D font is not part of the default mechanism. We make use of
+%D the \CONTEXT\ variables \type{\textface}, \type{\scriptface}
+%D and \type{\scriptscriptface}, which hold the current
+%D sizes.
+
+\defCWEBmacro\tentex%
+ {\font\next=cmtex10 at \textface
+ \fontextraspace\next\zeropoint
+ \next}
+
+\defCWEBmacro\sevenrm {\getvalue{\scriptface rmtf}}
+\defCWEBmacro\sevensy {\getvalue{\scriptface mmsy}}
+\defCWEBmacro\teni {\getvalue{\textface mmmi}}
+
+%D \macros{CWEBpt}{}
+%D
+%D The original macros are based on a 10~point bodyfont size. We
+%D therefore have to specify dimension in points a bit
+%D different. Specifications like .6pt are changed to
+%D \type{.06} times \type{\bodyfontsize}.
+
+\defCWEBmacro\CWEBpt {\bodyfontsize} % still dutch
+
+%D \macros{CEE,UNIX,TEX,CPLUSPLUS}{}
+%D
+%D Next come some logo's. It does not make much sense to use
+%D the \CONTEXT\ logo mechanism here, so we simply say:
+
+\defCWEBmacro \CEE/{{\mc C\spacefactor1000}}
+\defCWEBmacro \UNIX/{{\mc U\kern-.05emNIX\spacefactor1000}}
+\defCWEBmacro \TEX/{\TeX}
+\defCWEBmacro\CPLUSPLUS/{{\mc C\PP\spacefactor1000}}
+\defCWEBmacro \Cee{\CEE/} % for backward compatibility
+
+%D \macros{\ }{}
+%D
+%D Now we come to the real work: the short commands that make
+%D up the typography.
+%D
+%D \CWEBquote italic type for identifiers.
+
+\defCWEBmacro\\#1%
+ {\leavevmode\hbox{\it#1\/\kern.05em}}
+

+%D The latest version does things more automatically (and

+% %D For the moment we need the following patch. Adam T. Lindsay
+% %D found out that the following code produced an error:
+% %D
+% %D \starttyping
+% %D \startMPcode
+% %D draw begingraph(130mm,35mm);
+% %D setrange(0,0,10,22000);
+% %D glabel.lft(btex {correct 0--22000} etex rotated 90, OUT);
+% %D autogrid(itick.bot,grid.lft) withcolor .75white ;
+% %D endgraph;
+% %D \stopMPcode
+% %D
+% %D \startMPcode
+% %D draw begingraph(130mm,35mm);
+% %D setrange(0,50,10,22000);
+% %D glabel.lft(btex {wrong 50--22000} etex rotated 90, OUT);
+% %D autogrid(itick.bot,grid.lft) withcolor .75white ;
+% %D endgraph;
+% %D \stopMPcode
+% %D
+% %D \startMPcode
+% %D draw begingraph(130mm,35mm);
+% %D setrange(0,110,10,30000);
+% %D glabel.lft(btex {failed 110--22000} etex rotated 90, OUT);
+% %D autogrid(itick.bot,grid.lft) withcolor .75white ;
+% %D endgraph;
+% %D \stopMPcode
+% %D \stoptyping
+% %D
+% %D The bug is a rather nasty one and needs some tweaking in
+% %D the low level graph code. John Hobby suggested for the
+% %D moment to initialize \type {setrange} as follows:
+% %D
+% %D \starttyping
+% %D setrange(0,0,"22000","22000")
+% %D \stoptyping
+% %D
+% %D Folowing this suggesion, I provide the following
+% %D extension:

+% This file is a variation of the file pdfsync4context.tex that ships
+% with the pdfsync package (used by iTeXMac and TeXShop) by Piero
+% D'Ancona and Jérôme Laurens. I made the macros a bit more efficient
+% and added some basic tracing options as well as a few more options.
+% I made this one while playing a bit with the Mac and TeX). Maybe I'll
+% add a bit of support to the kernel in in order to get rid of redundant
+% markers. Also, this had better be rewritten in a bit less \pdf
+% dependent way so that it can also be supported by dvipdfmx. I could
+% write a generic file as well, but since there is already support for
+% other packages I'll not do that (now).

+%D This module is one big hack. This hack is not needed when
+%D using \ETEX, so there we simply load \PICTEX\ and quit.
+
+%D Not every package defines \type{\fiverm}, \PICTEX's pixel,
+%D so let's take care of that omision here. The actual loading
+%D of \PICTEX\ depends on the package. For \LATEX\ users we
+%D take care of loading the auxiliary ones too.

+%D \TEX\ provides 256 \DIMENSIONS\ and 256 \SKIPS. In \CONTEXT\
+%D this is no problem, but in packages that have many
+%D authors, one can be quite sure that a lot of \DIMENSIONS\ are
+%D allocated. Packages that use \PICTEX\ can therefore run out
+%D of \DIMENSIONS\ quite fast. This module was written as a
+%D reaction to persistent problems with loading \PPCHTEX\ in
+%D \LATEX\ and \PICTEX\ deserves a solution. I therefore
+%D dedicate this module to Tobias Burnus and Dirk Kuypers, who
+%D use \PPCHTEX\ in a \LATEX\ environment and suggested a lot
+%D of extensions to the repertoire of \PPCHTEX\ commands.
+%D
+%D This module presents a solution that is quite effective: all
+%D \DIMENSIONS\ are drawn from the pool of \DIMENSIONS\ and
+%D \SKIPS, depending on the availability. This is possible
+%D because \DIMENSIONS\ are \SKIPS\ without a glue component.
+%D Therefore we can use \SKIPS\ as \DIMENSIONS. However, some
+%D incompatibility can result from assignments that look like:
+%D
+%D \starttyping
+%D \somedimen=\someskip
+%D \stoptyping
+%D
+%D In such cases the \DIMENSION\ equals the fixed part of the
+%D \SKIP\ or in other words: this assignment strips off the
+%D glue. Because \PICTEX\ uses no glue components, I thought
+%D I could interchange both register types without problems,
+%D but alas, this didn't hold for all \DIMENSIONS.
+
+%D In \PLAIN\ \TEX\ the allocation macros are defined with (as)
+%D \type{\outer}. This means that they cannot appear inside
+%D macros, not even in an indirect way. We therefore have to
+%D redefine both \type{\newdimen} and \type{\newskip} to
+%D non||\type{\outer} alternatives. In most macro packages this
+%D redefinition already took place. We save the original
+%D meanings, so we can restores them afterwards.
+
+% \def\temporarynewdimen {\alloc@1\dimen\dimendef\insc@unt}
+% \def\temporarynewskip {\alloc@2\skip \skipdef \insc@unt}
+
+\let\normalnewdimen \newdimen
+\let\normalnewskip \newskip
+
+\let\temporarynewdimen\newdimen
+\let\temporarynewskip \newskip
+
+%D Here comes the trick. Depending on how many \DIMENSIONS\ and
+%D \SKIPS\ are allocated, the \type{\newdimen} assigns a
+%D \DIMENSIONS\ or \SKIP. \PLAIN\ \TEX\ allocates 15 \DIMENSIONS\
+%D and 17 \SKIPS. After loading \PICTEX, 71 \DIMENSIONS\ and
+%D and 71 \SKIPS\ are allocated. Indeed, \PICTEX\ needs 110
+%D \DIMENSIONS !
+%D
+%D \starttyping
+%D \def\newdimen
+%D {\ifnum\count11>\count12
+%D \let\next\temporarynewskip
+%D \else
+%D \let\next\temporarynewdimen
+%D \fi
+%D \next}
+%D \stoptyping
+%D
+%D When I was testing a new version of \PPCHTEX\ in \PLAIN\
+%D \TEX\ I had to find out that this exchange of registers
+%D sometimes leads to unwanted results. It took me some hours
+%D to find out that the source of errors originated in
+%D constructions like:
+%D
+%D \starttyping
+%D \ifdim\DimenOne<\DimenTwo whatever you want \else or not \fi
+%D \stoptyping
+%D
+%D When \type{\DimenOne} is a \SKIP\ and \type{\DimenTwo} is a
+%D \DIMENSION, \TEX\ scans for some optional glue component,
+%D like in:
+%D
+%D \starttyping
+%D \skip0=\dimen0 plus 10pt minus 5pt
+%D \stoptyping
+%D
+%D The most robust solution to this problem is:
+%D
+%D \starttyping
+%D \ifdim\DimenOne<\DimenTwo\relax right \else wrong \fi
+%D \stoptyping
+%D
+%D Some close reading of the \PICTEX\ source however learned me
+%D that this problem could be solved best by just honoring the
+%D allocation of \DIMENSIONS\ when the name of the macro
+%D explictly stated the character sequence \type{dimen}. A next
+%D implementation therefore automatically declared all
+%D \DIMENSIONS\ with this sequence in their names with
+%D \type{\dimen}. Again I was too optimistic, so now we do it
+%D this way (the comments are from \PICTEX, which like \TABLE,
+%D is an example of a well documented package):
+
+\temporarynewdimen\!dimenA %.AW.X.DVEUL..OYQRST
+\temporarynewdimen\!dimenB %....X.DVEU...O.QRS.
+\temporarynewdimen\!dimenC %..W.X.DVEU......RS.

+\temporarynewdimen\!yloc %..WB.....U.......S.
+\temporarynewdimen\!ypos %..........L.P..Q.ST
+\temporarynewdimen\!zpt %.AWBX.DVEULGP.YQ.ST
+
+%D Tobias tested this module in all kind of \LATEX\ dialects
+%D so we were able to find out that we also needed to declare:
+
+\temporarynewdimen\linethickness
+
+%D After all, the new definition of \type{\newdimen} became:
+
+\def\newdimen#1%
+ {\ifx#1\undefined
+ \ifnum\count11>\count12\relax
+ \temporarynewskip#1\relax
+ \else
+ \temporarynewdimen#1\relax
+ \fi
+ %\edef\ascii{\meaning#1}%
+ %\immediate\write20{\string#1 becomes \ascii}%
+ \else
+ %\edef\ascii{\meaning#1}%
+ %\immediate\write20{\string#1 already is \ascii}%
+ \fi}
+
+% This macro is as unreadable, inefficient and as compact as
+% can be, but uses no extra hash entries, which sometimes are
+% scarce too. A more readable alternative, that also takes
+% explicit \SKIPS\ into account, is included in the source.
+%
+% \def\doifregisterpreferenceelse#1#2#3#4%
+% {\def\dodoifregisterpreferenceelse##1#1##2##3\war{\if##2@}%
+% \expandafter\dodoifregisterpreferenceelse\string#2#1@@\war
+% #4%
+% \else
+% #3%
+% \fi}
+%
+% \def\newdimen#1%
+% {\bgroup
+% \escapechar=-1
+% \expandafter\doifregisterpreferenceelse\expandafter{\string\dimen}#1
+% {\egroup
+% \temporarynewdimen#1}
+% {\expandafter\doifregisterpreferenceelse\expandafter{\string\skip}#1
+% {\egroup
+% \temporarynewskip#1}
+% {\egroup
+% \ifnum\count11>\count12
+% \temporarynewskip#1\relax
+% \else
+% \temporarynewdimen#1\relax
+% \fi}}}
+
+%D Curious readers can still find the previous solution in
+%D the source. The next macro is used instead of
+%D \type{\input}. This macro also reports some statistics.
+
+\def\dimeninput#1 %
+ {\message{[before: d=\the\count11,s=\the\count12]}%
+ \input #1 \relax
+ \message{[after: d=\the\count11,s=\the\count12]}}%
+
+%D Now we can load \PICTEX:
+
+\loadpictex
+
+%D Finally we restore the old definitions of \type{\newdimen}
+%D and \type{\newskip}:
+
+\let\newdimen=\normalnewdimen
+\let\newskip =\normalnewskip
+
+%D and just hope for the best.

+%D We can combine both variants in one macro definition. Also, we
+%D can minimize the number of runs by checking for a change.

+%D JS: The call to R has \type {-q} in order to prevent banner,
+%D \type {--save} to make sure it saves the workspace after the run,
+%D \type {--restore} to make sure it reads any workspace from a
+%D previous session.

+%D The first attempt was purely \METAPOST\ based and spawned
+%D the typesetting to the \METAFUN\ handler. This method
+%D collects the cells, and directly passes them on to
+%D \METAPOST. This method is the cleanest, but has the
+%D disadvantage that one cannot embed hyperlinks or document
+%D dependent definitions in the cells. The implementation
+%D roughly looks as follows:
+%D
+%D \starttyping
+%D \def\startSTEPchart%
+%D {\bgroup
+%D \startMPdrawing
+%D input mp-step.mpii ; begin_step_chart ;

+%D \let\texts\stepcharttexts \def\text{\texts{}}}

+%D \def\stepchartcells#1#2%

+%D set_step_chart_cells(\MPstring{tdummy},\MPstring{bdummy}) ;
+%D \stopMPdrawing}
+%D
+%D \def\stepcharttexts#1#2%
+%D {\setMPtext{tdummy}{\strut\ignorespaces#1\unskip}% beter etex/btex
+%D \setMPtext{bdummy}{\strut\ignorespaces#2\unskip}% beter etex/btex
+%D \startMPdrawing
+%D set_step_chart_texts(\MPstring{tdummy},\MPstring{bdummy}) ;

+%D end_step_chart ;
+%D \stopMPdrawing
+%D \MPdrawingdonetrue
+%D \getMPdrawing
+%D \resetMPdrawing
+%D \egroup}
+%D \stoptyping
+%D
+%D This method has the advantage that it does the job in
+%D (virtually) one pass, while the next methods need multiple
+%D passes: one to build the table, another to synchronize the
+%D positions, and a third one beause the dimensions may have
+%D changed. The last pass is a result from the fact that
+%D positions are related to the page.
+%D
+%D The second attempt was based on tabulations and used the
+%D build in position tracking mechanism, which uses two
+%D position nodes per cell.
+%D
+%D This method collects the content in token list registers
+%D and build a table from them. In the collecting pass, the
+%D graphics are build stepwise. We need to collect because the
+%D order of definitions is not the same as the order of
+%D typesetting. We show this alternative too because it
+%D demonstrates how to apply backgrounds to table cells.
+%D
+%D \starttyping
+%D \newtoks\stepsonetop \newtoks\stepstwotop
+%D \newtoks\stepsonebot \newtoks\stepstwobot
+%D \stoptyping
+%D
+%D During the collecting phase, we temporarily have to
+%D increment the name space counter.

+%D \let\texts\stepcharttexts \def\text{\texts{}}}
+%D \stoptyping
+%D
+%D Now we collect the steps and texts, and in the process the
+%D graphic is built. Then we continue with building the table.
+%D
+%D Watch how we anchor the graphic to the main table box. This
+%D is needed since the graphic may be larger than the table
+%D itself. Actually, these small point took me the most time to
+%D digest, even with the right tools (anchors) already in

+%D We abandoned this method after some testing and went for
+%D a third one. It was this third method that evolved into the
+%D current mechanism.
+%D
+%D Since this method was not that efficient, a third one was
+%D implemented, which used one position per cell. So,

+%D \blank {\bf Here starts the real implementation!} \blank
+%D
+%D Because we want to build one graphic only we need to store
+%D the graphic directives. We also need to collect the cells,
+%D which are not defined in the order they show up. This
+%D solution uses multiple passes over the definitions. First
+%D the cells and texts are processed and the associated
+%D graphics are defined in the \METAPOST\ file. Next the
+%D lines are flushed. We need to do that in a second pass,
+%D because in order to determine the nature of the line,
+%D \METAPOST\ needs to know if the start and end cells exist.
+%D This need comes from the fact that we store the shapes
+%D and lines kind of directly with their associated colors and
+%D types, so that we can change the settings in between. So,
+%D changing for instance the line color, can take place
+%D locally.

+%D Scientific units can be typeset in math mode pretty well,
+%D but occasionally one has to take care of spacing.
+%D Furthermore, entering these units is not that natural as
+%D wanted. Therefore this module presents a more natural way of
+%D doing things, like:
+%D
+%D \starttyping
+%D 1.23 \Cubic \Meter \Per \Second
+%D \stoptyping
+%D
+%D This example shows that we use the order in which we say
+%D things, instead of typeset things. There is a separate
+%D manual for this module.
+
+%D Message number~1 deals with overruling the \type {\Degrees}
+%D macro defined in the core modules. Let's say that this is
+%D an upward compatibility issue.

+%D This runtime loadable module implements a way of defining
+%D units. The core macro is \type {\dimension}, a rather clever
+%D one that is able to cooperate with some other dimension
+%D related macros. As said, this module enables user to enter:
+%D
+%D \startbuffer
+%D some 10 \Square \Meter \Per \Second or more
+%D \stopbuffer
+%D
+%D \getbuffer
+%D
+%D as:
+%D
+%D \typebuffer
+%D
+%D The units itself are implemented as synonyms.
+%D
+%D \starttyping
+%D \definesynonyms [unit] [units] [\unitmeaning]
+%D \setupsynonyms [unit] [textstyle=\dimension]
+%D \stoptyping
+%D
+%D This definition means that we can ask for the meaning of a
+%D unit using \type {\unitmeaning} and get a list of used
+%D units by saying \type {\placelistofunits}
+%D
+%D We have to use the command \type {\unitmeaning} instead
+%D of \type {\meaning}, simply because the latter is a \TEX\
+%D primitive we don't want to loose. We use the label text
+%D mechanism for translations.
+
+%D \macros
+%D {dimension}
+%D
+%D The core of this module is the low level macro \type
+%D {\dimension}. Before presenting this macro, it's best to
+%D look at some applications, because it's supposed to show
+%D some intelligence that can beter be understood from the
+%D context.
+%D
+%D The next useless examples show some of the cases we want
+%D to handle in a proper way.
+%D
+%D \startbuffer
+%D ... 10 \Square \Meter \Per \Volt \
+%D ... 10 \Square \Meter \Volt \
+%D ... 10 \Meter \Volt \
+%D ... 10 \Milli \Square \Meter \Per \Volt \
+%D ... 10 \Square \Milli \Meter \Per \Volt \
+%D ... 10 \Meter \Times \Meter \
+%D ... 10 \Square \Meter \Times \Meter \
+%D ... 10 \Square \Milli \Meter \Times \Meter \
+%D \stopbuffer
+%D
+%D \typebuffer
+%D
+%D Becomes:
+%D
+%D \getbuffer
+
+%D \macros
+%D {mathematicstypeface, dimensiontypeface,
+%D dimensionhalfspace, dimensionbackspace}
+%D
+%D There are some low level constants, that can be changed
+%D when needed. Some day I will write a decent setup command.
+
+\def\mathematicstypeface{\rm}
+\def\dimensiontypeface {\tf}
+
+\def\dimensionhalfspace {\ifmmode\,\else\hskip+.1em\relax\fi}
+\def\dimensionbackspace {\ifmmode\!\else\hskip-.1em\relax\fi}
+
+%D \macros
+%D {smashdimensionpower}
+%D
+%D Sometimes the baseline distance is not enough to provide
+%D for superscripts, so we smash their height by default.
+
+\newif\ifsmashdimensionpower \smashdimensionpowertrue
+
+%D The dimension mechanism uses a lot of signals to keep
+%D track if the current state.
+
+\newsignal\dimensionsignal
+\newsignal\dimensionpowersignal
+\newsignal\dimensionmidfixsignal
+\newsignal\dimensionaddfixsignal
+
+\let\thedimensionprefix = \empty
+\let\thedimensionpower = \empty
+
+%D \macros
+%D {spaceddimensions,textdimensions}
+%D
+%D The actual definition of \type {\dimension} overruled the
+%D one in the core modules. The boolean can be used to
+%D force spacing between units. Vergelijk {\Newton \Meter}
+%D eens met {\spaceddimensionstrue \Newton \Meter}. The
+%D rather ugly test prevents problems with nested dimensions.
+
+\newif\ifspaceddimensions \spaceddimensionsfalse % user switch
+\newif\iftextdimensions \textdimensionsfalse % user switch
+
+%D You can see the consequence of forcing text dimensions
+%D when you compare the following code:
+%D
+%D \starttyping
+%D {\rm test \Square \Meter \Per \Second\ ziezo\Degrees} \par
+%D {\ss test \Square \Meter \Per \Second\ ziezo} \par
+%D {\tt test \Square \Meter \Per \Second\ ziezo}

+%
+% it would be interesting to rewrite this module with todays
+% experiences and new context functionality, maybe ...
+
+% Deze module ondersteunt het zetten van chemische
+% (structuur)formules. Hoewel de macro' zijn afgestemd op
+% CONTEXT, zijn ze ook buiten deze zetomgeving te gebruiken.
+%
+% Dit is, afgezien van updates, de definitieve versie van
+% PPCHTEX. Gebruikersgemak, eenvoud, flexibiliteit, en
+% snelheid zijn inmiddels redelijk geoptimaliseerd. Dit neemt
+% niet weg dat hier en daar nog verbetering mogelijk is. Dit
+% zal dan ook nog gebeuren.
+%
+% Volgende versies zullen tenminste dezelfde functionaliteit
+% hebben. We houden ons natuurlijk het recht voor de kwaliteit
+% van de output te verbeteren. Daarnaast staan nog op het
+% wensenlijstje:
+%
+% - optimaliseren in termen van proces-tijd
+% - aanpassen naamgeving van interne macro's
+% - toevoegen van functionaliteit
+% - in \x!-vorm omzetten van GIVES, TB enz.
+%
+% De mix tussen engels en nederlands lijkt soms verwarrend.
+% Meestal zijn verborgen macro's engels en zichtbare macro's
+% nederlands. Het gebruik van [ ] en { } sluit aan op andere
+% Context-macro's. Hetzelfde geldt voor instellingen en
+% \start-\stop-constructies.
+%
+% De schijnbaar overbodige \bgroup-\egroup constructie
+% garandeert aansluiting bij de Context-macro's voor het
+% plaatsen van figuren, tabellen en andere floats.
+%
+% Binnen Context worden de macro's geladen met
+% \gebruikextras[chemie]. Daarbij wordt een passende melding
+% getoont. Buiten Context genereren we een melding:

+% Om te voorkomen dat sub- en superscripts botsen passen we
+% wat fontdimen's aan (Knuth, The TeXBook, p179). Helaas
+% kunnen deze instellingen niet lokaal worden gehouden door
+% groeperen, vandaar dat een en ander moet worden geset ‚n
+% gereset.
+%
+% Er dient een relatie te worden gelegd met de afmetingen
+% van de letters. In een eerdere versie werden daartoe de
+% \fontdimen's opgehoogd. Omdat dit problemen gaf bij
+% scaled fonts, is bij nader inzien gekozen voor de
+% onderstaande oplossing, waarbij de nieuwe waarden worden
+% afgeleid van de x-height (\fontexheight). De factor 0.70
+% is min of meer experimenteel vastgesteld. Soms worden de

+% mailing list by Giuseppe Bilotta, along with the right
+% typescripts.

+% already loaded: \usemodule[greek]
+
+\mainlanguage[english]
+
+\starttext
+
+We can easily use plain English for normal text, and then switch
+to greek when we want; as a first try we type the lower and
+upper case 26 letters of the latin alphabet and see how they come
+out in greek:
+
+\startgreek
+a b c d e f g h i j k l m n o p q r s t u v w x y z \par
+A B C D E F G H I J K L M N O P Q R S T U V W X Y Z
+\stopgreek
+
+As it can be observed, some uppercase letters have strange
+outcomes; also, j gives \greek{j} and c gives the
+end-of-word sigma \greek{c}; interestingly, s gives either the
+normal sigma or the end-of-word one, depending on whether it's at
+the end of the word or not: \greek{satrapws}.
+
+Of course we can use the various diacritical signs: accents
+(\greek{`a, 'a, ~a}), breathings (\greek{<r, >w, a"}) and
+subscribed iotas (\greek{a|, h|, w|}) (these last are pretty ugly in my
+opinion); observe how they automatically get the correct position
+with uppercase letters: (\greek{`A, 'A, ~A, <A, >A, A|}).
+
+Can the thing be used for serious work?

+%D This module is for producing acticles for \from[pracjourn]. It merely copies the
+%D layout of the the \LATEX\ class \filename{pracjourn.cls} available from
+%D \pracjourn\ website (\url[pracjourn]). This module has a filename synonym
+%D \filename{pracjourn}. So to use this module, you can write:
+%D \starttyping
+%D \usemodule[pracjourn]
+%D \stoptyping
+%D A sample document is given at the end of this file. The typeset sample can
+%D be obtained by
+%D \starttyping
+%D texmfstart texexec --mode=demo s-ptj-01.tex
+%D \stoptyping
+%D The documentation is written as comments. If you want to see a \PDF\ copy
+%D \starttyping
+%D texmfstart texexec --module s-ptj-01.tex
+%D \stoptyping
+
+\startmodule[pracjourn]
+
+\unprotect
+
+%D First let's setup the paper size and layout for \pracjourn. I am actually not
+%D sure about the \quote{official} layout requirement for \pracjourn\ and have
+%D reverse engineered the layout from the typeset \LATEX\ examples. If you
+%D feel that anything is wrong here, please let me know.
+

+ footer=.5in,

+
+%D Next we do the font setup. \pracjourn\ uses mathpazo for roman and math faces and
+%D uses latin modern for sans serif and monotype. For the main face, 12pt is
+%D used with a 15.5pt baseline skip. Font protrusion is enabled, but font
+%D expansion is not. We follow these conventions. \CONTEXT\ uses Pagella fonts
+%D from \TEX{gyre} project, so we use them instead.

+%D The variables for the article are stored in the \mono{pracjourn} namespace.
+%D To initialize these variables use
+%D \starttyping
+%D \setvariables
+%D [pracjourn]
+%D [ title=Tile of the Article,
+%D author=Name of Author,
+%D address=Write your Address,
+%D revision={d=14,m=11,y=2006},
+%D copyright=Whatever you want,
+%D ]
+%D \stoptyping
+%D \mono{title} and \mono{author} should always be entered (even though this
+%D module does not make them mandatory, it makes little sense to have an
+%D article without a title or author. Other variables are optional. If a
+%D revision is not written, current date will be used to show the revision.
+%D Other variables for the article are the author's email address and website
+%D url. Due to catcode problems, it is not always possible to reliably enter
+%D these using the variable mechanism. To enter these use \type|\useURL|
+%D \starttyping
+%D \useURL[email][mailto:address@whatever.com][][address@whatever.com]
+%D \useURL[website][link to your homepage]
+%D \stoptyping
+%D If either of these \URL's are not present, they will be silently ignored
+%D while generating the title.

+\setvariables [pracjourn] [ title=]
+\setvariables [pracjourn] [ author=]
+\setvariables [pracjourn] [ address=]
+\setvariables [pracjourn] [copyright=]
+\setvariables [pracjourn] [ revision=]
+
+%D We use the buffer \filename{abstract} for the abstract. So to enter the
+%D abstract, write
+%D \starttyping
+%D \startbuffer[abstract]
+%D Write your abstract
+%D \stopbuffer
+%D \stoptyping
+%D Right now, there is no mechanism to inhibt abstracts. In case someone
+%D requires it, such a mechanism is easy to implement.
+
+\startbuffer[abstract]
+\stopbuffer
+
+%D The actual title with the additional information is typset by calling
+%D \starttyping
+%D \setups{title}
+%D \stoptyping
+%D Remember that the \type|\setvariables[pracjourn][...]| step must be done
+%D before \type|\setups{title}|.
+
+\setuphead
+ [title]
+ [style=\titlefont,
+ after={\blank[big]}]
+
+%D Next we define internal frames to take care of the layout of the extra
+%D material in the title.
+
+\defineframed
+ [pracjourninfotitle]
+ [ frame=off,
+ strut=yes,
+ width=0.1\textwidth,

+ \egroup\endgraf}
+
+%D Now we take care of the actual layout of the title. Most of this is
+%D heuristic, as I was trying to get the same visual effect as the
+%D \filename{pracjourn.cls} class. If something does not match, please let me
+%D know. The information is typeset as
+%D \starttyping
+%D \hfill <box of .1\textwidth> \hfill <box of .85\textwidth>
+%D \stoptyping
+%D at 11pt size. We also add the title and author information in the \PDF\

+%D Next we setup the header and footer for the first page. \pracjourn\ formats the
+%D header as
+%D \startlines
+%D The PracTeX Journal, year, No. number
+%D Article revision year/mm/dd
+%D \stoplines

+
+%D For rest of the pages, page number is printed on the middle of the footer.
+
+\setuppagenumbering [location={footer,middle}, style=mediaeval]
+
+%D Next we setup the formating for the sections. \pracjourn\ wants font sizes of
+%D 17pt, 14pt, and 12pt respectively for section, subsection, and
+%D subsubsection. By default, \tex{tfa} is 1.2, \tex{tfb} is 1.4, so the sizes
+%D come out close to what is required. The section number is typset in
+%D oldstyle fonts.
+
+\setuphead
+ [section,subject]
+ [ style=\tfb,
+ numberstyle=mediaeval,
+ before={\blank[2*big]},

+\setuphead

+
+\setuphead
+ [subsubsection,subsubsubject]
+ [ style=\tf,
+ numberstyle=mediaeval,
+ before={\blank[medium]},
+ after={\blank},
+ ]
+
+%D Now we setup the captions. The captions head are set in normal font, and
+%D the caption number is set in oldstlyle.
+
+\setupcaptions [headstyle=normal,stopper=:,conversion=mediaeval]
+
+%D Footnotes are placed in a box with a width of 1.5em. The footnote numeral
+%D are set in oldstyle font.
+
+\setupnote
+ [footnote]
+ [margindistance=0em,
+ conversion=mediaeval,
+ command=\pracjournfootnote,
+ ]
+
+\setupnotedefinition [footnote] [location=left,hang=1]
+
+\def\pracjournfootnote#1{\hbox to 1.5em{#1.}}
+
+%D \pracjourn\ uses dash as the first level of itemize and text period as the second
+%D level. The third level is left unspecified.
+
+\definesymbol [1] [{\symbol[dash]}]
+\definesymbol [2] [\periodcentered]
+
+\setupitemize [each] [packed]
+\setupitemize [1] [packed,autointro] [margin=1em]

+%D We enable colors, interaction and bookmarks.
+
+\setupinteraction [state=start,color=darkred,style=normal]
+\setupurl [color=darkred]
+\setupcolors [state=start]
+\placebookmarks [section,subsection] [section]
+
+%D We setup medium indenting, whitespace and blanks.
+
+\setupindenting [medium,yes]
+\setupwhitespace [medium]
+\setupblank [medium]
+
+%D We define logos for \PRACTEX\ and \pracjourn. These definitions are copied from
+%D \filename{pracjourn.cls} and can be accessed by \type|\PracTeX|,
+%D \type|\PRACTEX| and \type|\pracjourn|.
+
+\def\PracTeX{Prac\kern-0.07em\TeX}
+\def\PRACTEX{\PracTeX}
+\def\pracjourn {The \PRACTEX\ Journal}
+
+%D \filename{pracjourn.cls} provides two macros \type|\ctanfile| and
+%D \type|\ctanloc|. I am not sure what is the advantage of these macors. If
+%D you want to use these macros, you can use the \type|\useURL| mechanism of
+%D \CONTEXT. For example
+%D \starttyping
+%D \useURL[pracjourn][http://ctan.org/get?fn=/macros/contrib/latex/pracjourn][][\mono{CTAN:macros/contrib/latex/pracjourn}]
+%D The \LATEX\ style files for \pracjourn\ is localed at \from[pracjourn]
+%D \stoptyping
+
+%D For the final version of the paper, the string \quotation{The PracTeX
+%D Journal year, No x} is written on the header. This only happens when the
+%D current directory contains a file \filename{_iss.tex} which contains string
+%D like \quotation{pracjourn 2006 No 04, 2006-11-15}. This step is usually taken in
+%D the final production of the article. If this file is absent, \quotation{For
+%D submission to the PracTeX Journal} is written instead. The next macros are
+%D used to parse this file.

+%D If you have a self contained &xml; file, you need to signal &context; the

+%D the author is <em>consistent</em> in his decisions on what to emphasize.

+%D
+%D <![CDATA[

+%D \elements {table,tr,td}
+%D

+%D There are (currently) three table mechanisms in &context;. One of them
+%D resembles the well known &html; tables.

+%D <tr> <td>one</td> <td>a</td> <td>first </td> </tr>
+%D <tr> <td>two</td> <td>b</td> <td>second</td> </tr>
+%D </table>
+%D <?context-command \stoplinecorrection ?>
+%D
+%D As you can see here, we use a similar syntax but stick to the &context;
+%D attributes (which provide quite advanced control over the layout).
+%D

+%D The second mechanism that we support is tabulation. The advantage of this
+%D mechanism is that it it well tuned for tables that have much text in the

+%D The selection spec:

+\setvariables

+ [selection=,
+ file=x-corres.xml] % fall back
+
+%D First we define the group expansion pass:

+\startsetups[contacts:collect]

+
+ \defineXMLprocess[contacts]

+ \defineXMLignore [contactgroup]
+
+ \defineXMLargument [contactfile]

+\def\XMLaddcontacttoselection#1%

+%D See \type {x-fig-00.tex} for more information on how to use
+%D and generate figure databases. This file loads the file
+%D named \type {\jobfilename} (\TEXEXEC\ will set this
+%D variable). You can apply this style to a database by
+%D saying:
+%D
+%D \starttyping
+%D texexec --pdf --use=fig-make yourfile.xml
+%D \stoptyping
+%D
+%D The following modes are supported:
+%D
+%D \starttabulate[|lT|l|]
+%D \NC letter \NC map the preview on letter size \NC \NR
+%D \NC compact \NC use an alternative presentation \NC \NR
+%D \stoptabulate
+%D
+%D The resulting file has the following characteristics:
+%D
+%D \startitemize[packed]
+%D \item the document is split into three sections: first each
+%D figure is shown at its own page, then an overview of
+%D figures is shown with some data alongside, and
+%D finally an index and table of contents shows up
+%D \item there is no title page, which means that one can
+%D access a figure by page number without offset
+%D \item the document is opened at the first overview page,
+%D that is, when the viewer supports it
+%D \item the graphic is shown 3~times: on a page of its own,
+%D scaled to a fixed dimension, and relative to a4 or
+%D letter paper size
+%D \item the labels can be accessed in an index and list at
+%D the end of the document
+%D \stopitemize
+%D
+%D We use named destinations, which means that one can
+%D access a figure by name from an external application.

+%D Most time went into figuring out the specifications, especially
+%D because there are no examples included. Samples that circulate on the
+%D web are often border cases and torture test and don't have much to do
+%D with real live. Another complication lays in the inheritance model:
+%D some of the attributes are inherited. This also leaves some room for
+%D interpretation, for instance do values that are used at a certain
+%D point migrate downwards or not.
+%D
+%D The \CONTEXT\ \XML handler can deal with attributes in several ways
+%D and for this purpose I have played with a few experimental mechanisms
+%D just to end up with the existing begin/end mechanism combined with
+%D a recursive attribute resolver which means that one has to implicitly
+%D ask for an inherited attributes. This approach is probably one of the
+%D most efficient ways of dealing with formatting objects in \CONTEXT,
+%D unless of course I start adding rather specific support to the kernel.
+%D
+%D This module is rather experimental. More information about its usage
+%D can be found in the \FOXET\ manual.
+
+%D Since we're not dealing with the fine points of typesetting here, we
+%D can safely ignore \TEX's warnings about overful or underful boxes.
+
+\dontcomplain
+
+%D We will use fonts that have the characters in the normal (ascii)
+%D slots. We will also use the stupid verbatim handler.

+\setupbodyfont[pos,10pt]
+
+%D There are a couple of predefined colors. Don't ask me why, but
+%D formatting objects are not a fresh start but a mix of existing
+%D technologies. Color support is poluted by cascading stylesheets.
+%D
+%D Because hexadecimal color specifications are not enabled by
+%D default, this feature has to be enables by loading the appropriate
+%D color module. Here we define colors in \RGB\ values because we
+%D don't want to loose accuracy.

+
+%D We will organize the attribute definitions in a similar fashion as in
+%D the specification. Unfortunately there are more sets defined in there
+%D than are actually used, so the definitions later on will look a bit
+%D messy.
+%D
+%D Quite some attributes can be inherited, which means that they can
+%D end up in all elements and influence those way down the tree.

+%D We will speed up the process of setting up attributes by compiling the
+%D definitions. Sometimes we need to access attributes explicitly by
+%D element (for instance when handling regions). We also need to deal
+%D with nested elements (for instance blocks) or a sequence of similar
+%D ones, while we may not always want to use grouping. As a result, the
+%D next series of definitions and macros are quite ugly. The begin|/|end
+%D is needed in order to comfortably fetch attribute values from
+%D ancestors.

+% we can follow two approaches: set the attributes global, using
+%
+% \defineXML...[tag][prefix][empty]
+%
+% in that case we trust the fo-file to be correct, i.e. the xslt style
+% sheets should not put attributes in the wrong places; however, we need
+% to do that with care, since for instance the attributes of some objects
+% (regions) are used mixed
+%
+% \defineXMLprocess [fo:root] [XMLFO] [test=unset]
+%
+% \defineXMLenvironment [fo:block-container] [XMLFO]

+% <fo:block test='last'>last:</fo:block>
+% </fo:root>
+% \stopXMLdata
+%
+% the other approach is to set the attributes explicitly for each
+% element, which is slower but more robust
+%
+% A mix is:
+%
+% \defineXMLenvironment
+% [fo:root]
+% [test=unset]
+% {\beginXMLelement}
+% {\endXMLelement}
+%
+% \defineXMLenvironment
+% [fo:block-container]

+%C details.

+%D Remark: from now on this is a module and no longer an xtag
+%D filter. In due time it will replace the older renderer (which
+%D we will keep around for sentimental reasons). This variant has
+%D no namespace support yet, but eventually we will use a \MKIV\
+%D version.

+%D Then we start defining the rendering macros:

+\writestatus{loading}{ConTeXt XML Macros / MathML}
+
+\startmodule [mathml]
+
+%D First we load the entities:
+
+\usemodule[newmme]
+
+% \setupmodule[a=c]
+% \setupmodule[a=c]
+
+\unprotect
+
+\def\MMLrm{\mr}
+
+\def\MMLseparator#1{{#1}} % nils space after separator
+
+%D First we define some general formula elements.
+

+ {\dostopXMLformula}

+%D Since I only had the draft of MathML 2 as example of
+%D rendering, there are probably a lot of omissions and
+%D misinterpretations. At least I learned some bits and
+%D pieces of math rendering.
+%D
+%D The main complications were not so much the math, but to
+%D find the most efficient way to handle elements without
+%D spacing beging messed up. The first implementation was
+%D aimed at getting reasonable output, this second
+%D implementation is already better in terms of handling
+%D nesting, and I will definitely need a third one that has
+%D more efficient and less ugly code.
+%D
+%D The \TEX\ part is not that complicated and once the
+%D preprocessor was okay, the rest way just a lot of keying
+%D and testing. It all comes down to gobbling, redefining,
+%D and not so much to parsing.
+%D
+%D The second implementation expanded the whole math sequence
+%D into an internal \TEX\ representation. This is a rather clean
+%D and fast process. Filtering and testing takes place by
+%D redefining the internal representation macros.
+%D
+%D The third implementation may look a bit more messy in some
+%D respects. This is because in \TEX\ it's not that trivial to
+%D implement a tree handler. We use a stack for the \type {apply}
+%D element and other sequential content. Occasionally we need to
+%D peek into child elements which involves messy code. This
+%D implementation is closer to the normal \XML\ handling in
+%D \CONTEXT.
+
+%D We start with the parent elements and the option handler.

+% apply
+%
+%D We use inner and grouping (begin/end and no b/e) else we
+%D get problems with 1/2(1+2) and alike (todo: ask taco).
+%D
+%D The problem with apply is that we need to take care of
+%D several situations, like:
+%D
+%D \starttyping
+%D <apply> <.../> ...
+%D <apply> <fn> ...
+%D <apply> <apply> <ci> ...
+%D <apply> <apply> <fn> <ci> ...
+%D \stoptyping

+%D version 3 the following definitions may be sub optimal or
+%D more complex than actually needed.

+%D title=\CONTEXT\ Style File,
+%D subtitle=Figure Base Generation,
+%D author=Hans Hagen,
+%D date=\currentdate,

+%C
+%C This module is part of the \CONTEXT\ macro||package and is
+%C therefore copyrighted by \PRAGMA. See mreadme.pdf for
+%C details.
+
+%D See \type {x-fig-00.tex} and \type {x-fig-04.tex} for more
+%D information on how to use and generate figure databases.
+%D This file loads the file named \type {\jobfilename}
+%D (\TEXEXEC\ will set this variable). You can apply this
+%D style to a database by saying:
+%D
+%D \starttyping
+%D texexec --pdf --use=fig-make yourfile.xml
+%D \stoptyping
+%D
+%D The following modes are supported:
+%D
+%D \starttabulate[|lT|l|]
+%D \NC letter \NC map the preview on letter size \NC \NR
+%D \NC compact \NC use an alternative presentation \NC \NR
+%D \NC clipgrid-distance \NC add a copy with grid overlayed \NC \NR
+%D \NC clipgrid-steps \NC add a copy with grid overlayed \NC \NR
+%D \NC previewpage-A4 \NC show graphic relative to A4 \NC \NR
+%D \NC previewpage-letter \NC show graphic relative to letter \NC \NR
+%D \NC previewpage-S6 \NC show graphic relative to S6 \NC \NR
+%D \stoptabulate
+%D
+%D The resulting file has the following characteristics:
+%D
+%D \startitemize[packed]
+%D \item the document is split into three sections: first each
+%D figure is shown at its own page, then an overview of
+%D figures is shown with some data alongside, and
+%D finally an index and table of contents shows up
+%D \item there is no title page, which means that one can
+%D access a figure by page number without offset
+%D \item the document is opened at the first overview page,
+%D that is, when the viewer supports it
+%D \item the graphic is shown 3~times: on a page of its own,
+%D scaled to a fixed dimension, and relative to a4 or
+%D letter paper size
+%D \item the labels can be accessed in an index and list at
+%D the end of the document
+%D \stopitemize
+%D
+%D We use named destinations, which means that one can
+%D access a figure by name from an external application.

+%D A figure base coded this way looks like:

+%D For the beginning we have used \TEXUTIL\ to hels us deal with
+%D graphics whose dimensions could not be determines and|/|or to
+%D provide placeholder info for graphics that were not available.
+%D Much of this functionality is now moved to \RLXTOOLS\ and
+%D therefore it makes sense to reimplement the code that deals with
+%D producing an overview of grapghics as well. At the same time we
+%D move some \TEX\ code from \TEXEXEC\ to here.
+%D
+%D Because the show commands are not used in real documents, but
+%D only for special purposed, it does not harm that this
+%D functionality is now part of a module. We no longer use the
+%D parsing code in \TEXUTIL, but rely on \IMAGEMAGICK's
+%D identify functionility.
+%D
+%D At the end of the file we kept the old code from \type {core-fig}.

+%D Schema support was implemented right after euro\TeX\ 2001,

+%D testing it.
