+========================
+Features Not Implemented
+========================
+Nesting
+*******
+Proper nesting. So far only lists support real nested structures.
+There's no way you could have real paragraphs or bulleted lists
+inside table cells. The problem is that with true nesting some
+jobs like the dissection of tables would have to be moved from
+the formatter to the parser. If you feel you need thoroughly
+nested structures -- e.g. grid tables in footnotes or bullet lists
+inside simple tables inside enumerations inside quotations inside
+footnotes -- you should consider including |CONTEXT| code as
+substitution directives. (OTOH docutils' new and old LaTeX
+formatter seems to have problems with tables in footnotes as
+well. Not to mention its preference for enclosing random nested
+structures in ``quote``-environments.)
+
+Should you find yourself in desparate need of tables or whatever
+structures inside footnotes then I might agree to find a solution
+if you ask.
+
+Tabs
+****
+The |rst| specification requests that tabs (ASCII no 9) be
+treated as spaces_. Although the matching patterns should be
+neutral with respect to tabs, I never tested them, neither do I
+guarantee that they will work anywhere. Converting your tabs to
+spaces might be a good preparation for an |rstcontext| run.
+
+.. _spaces: http://docutils.sourceforge.net/docs/ref/rst/restructuredtext.html#whitespace
+
+Hyperlinks
+**********
+The hyperlink implementation should be fine in general use if you
+avoid certain situations.
+
+- Never ever call your hyperlink targets ``anon_#``, where ``#``
+ stands for any integer. Just don't do it, OK? Great.
+
+- Referencing a structure element like a section heading by means
+ of an *empty link block* does work. However, if the element in
+ question requests a page break (e.g. the vanilla
+ ``\chapter{#1}`` command), the reference will link to the
+ previous page instead and become useless. You can avoid this
+ behaviour by referencing the section directly or by targetting
+ the first paragraph in the section instead.
+
+- Link chaining does not work with internal references. This is
+ considered a low-priority bug and will be addressed during the
+ next big hyperlink overhaul.
+
+Module
+******
+
+A module for MkIV is planned. Actually, the converter was
+thought of as a module for direct rendering of |rst| input
+initially but certain objections diverted me from this path.
+
+- *Typography*. It’s all about the details. No matter how good your
+ converter is, it still won’t reach |TEX|’s omnipotence and
+ flexibility. |rstcontext| is a tool to generate raw material
+ for your typesetting job, not a typesetting system in itself.
+
+- *Testing*. Never underestimate the insights gained from reading
+ the resulting |CONTEXT| file. Quite some effort has been
+ undertaken to make it human-readable, especially the setups.
+
+- *MkII*. I’m not an MkII user at all save for rapid testing and
+ the occasional check for the sanity of |CONTEXT|’s behaviour.
+ Slow hardware forces me to rund |PDFTEX| instead of |LUATEX|
+ whenvever I need some result as quick as possible, so I wanted
+ to keep the code MkII clean. Do not expect Unicode (as in
+ this document) to work.
+
+During the development readability of the generated code was
+alway one of the main goals of |rstcontext|. Quite some computing
+effort is made to reflow even simple things as paragraphs into
+a shape understandable by more than only the |TEX| machine.
+If you should at one point decide that your project is
+ripe for the typographical finish and you want to add local
+changes in form of |TEX| code only, you should be able to use the
+output of |rstcontext| as starting point.
+
+=====
+Usage
+=====
+At the moment, |rstcontext| needs to be called as a separate
+program. It is written for use with the Lua interpreter of
+|LUATEX|, ``texlua``, whose libraries and extended capabilities
+it uses. Therefore, |rstcontext| might not run at all on other
+Lua installations, at least not without modification of the
+source. Fortunately, every |CONTEXT| user is equipped with
+|LUATEX| nowadays so this dependency should be trivial.
+
+To generate |CONTEXT| code from a |rst| document named
+``infile.rst``, call ``rst_parser.lua`` through ``texlua``: ::
+
+ $texlua rst_parser.lua infile.rst outfile.tex
+
+You should now have a file ``outfile.tex`` that is ready to be
+run by |CONTEXT|. With some exceptions the generated code is
+downward compatible with MkII, thus it does not matter for a
+start whether you decide to test it with ``texexec`` or
+``context``.
+
+The resulting |TEX| file has rather a basic layout, if at all.
+This is intentional as you are expected to include it in a
+document after your own setups.
+An example for prepended setups can be found in the environment
+for this manual (``doc/manual.tex``).
+
+.. caution::
+ The output of |rstcontext| automatically inserts necessary
+ setups for the components found in the input. Therefore, the
+ ``\starttext`` and ``\stoptext`` commands are part of the
+ output and may not be specified in your setups file.
+ For now you have to use the |CONTEXT| command
+ ``\appendtoks <token> \to \starttext`` to add content like
+ title pages and indices to the result. This mechanism works
+ reliable as long as you have an eye on the order in which the
+ tokens are given. Again, have a look at ``manual.tex`` to get
+ an impression how useful this can be. User hooks for these
+ and other common constructs are thought of but have yet to be
+ implemented.
+
+To build the documentation, first ``cd`` to the root directory of the
+repository. Now run |rstcontext| as follows: ::
+
+ $texlua rst_parser.lua doc/documentation.rst doc/doc.tex
+
+Then change to the ``doc`` directory and run |CONTEXT| on
+``manual.tex``. Voilà, you have successfully built ``manual.pdf``.
+
+=========
+Examples
+=========
+
+|rstcontext| was developed for the largest part by going through
+the |rst| specification_ step by step and tested against the
+examples given both in the spec and in the `quick reference`_.
+Therefore you should refer to those examples first (and drop me a
+note immediately if any of them stopped working).
+All kinds of text blocks and inline markup have been implemented
+with the exception of anything mentioned in the section on
+`Features Not Implemented`_.
+Some of them that I have not found a real-world usage for (such
+as *definition lists*) do not yet have a presentable output --
+there is room for improvements that should be supplied by
+somebody who actually uses those features.

+.. _quick reference: http://docutils.sourceforge.net/docs/user/rst/quickref.html
+
+Block Quotes
+************
+
+The *block quote* syntax is fully supported, including
+attributions. For instance, the next snippet: ::
+
+ Some people have made the mistake of seeing Shunt’s work as a
+ load of rubbish about railway timetables, but clever people
+ like me, who talk loudly in restaurants, see this as a
+ deliberate ambiguity, a plea for understanding in a
+ mechanized world.
+
+ --- Gavin Millarrrrrrrrrr on Neville Shunt
+
+gets you a neatly indented quotation, typeset in a slightly
+smaller font magnitude.
+
+ Some people have made the mistake of seeing Shunt’s work as a
+ load of rubbish about railway timetables, but clever people
+ like me, who talk loudly in restaurants, see this as a
+ deliberate ambiguity, a plea for understanding in a
+ mechanized world.
+
+ --- Gavin Millarrrrrrrrrr on Neville Shunt
+
+Don’t forget proper indentation.
+
+Numbered List
+*************
+
+Save for nesting lists are fully implemented in |rstcontext|.
+The following code typesets a triple-nested list with different
+kinds of bulleting / numbering: ::
+
+ i First order list, first entry.
+
+ ii First order list, second entry.
+
+ iii First order list, third entry.
+
+ - Second order list, first entry.
+
+ # Third order list, first entry.
+
+ # Third order list, second entry.
+
+ # Third order list, third entry.
+ Real nesting rules!
+
+ - Second order list, second entry.
+
+ iv First order list, fourth entry.
+
+ v First order list, fifth entry.
+
+The result looks like this:
+
+i First order list, first entry.
+
+ii First order list, second entry.
+
+iii First order list, third entry.
+
+ - Second order list, first entry.
+
+ # Third order list, first entry.
+ # Third order list, second entry.
+ # Third order list, third entry.
+ Real nesting rules!
+
+ - Second order list, second entry.
+
+iv First order list, fourth entry.
+
+v First order list, fifth entry.
+
+.. caution::
+ Don’t forget the blank lines between list items.
+
+==========
+Directives
+==========
+Admonitions
+************
+The following admonition directives have been implemented:
+
+Caution
+-------
+The *caution* directive results in the text being prefixed by one
+“dangerous bend” symbol in order to resemble the “wizards only”
+passages of the TeXbook.
+For example, the directive: ::
+
+ .. caution:: White mice do worse in experiments than grey mice.
+
+will result in the following:
+
+.. caution:: White mice do worse in experiments than grey mice.
+
+Danger
+------
+Similar to the *caution* directive, the *danger* directive
+prefixes the given text with two “dangerous bends” giving it the
+look of Knuths’s “esoteric” annotations.
+
+.. danger:: Be nice to the parser:
+ Don’t forget to align paragraphs that end a literal
+ block!
+
+
+Images
+******
+Including pictures is easy using the *image* directive: simply
+supply it the name of the image file as in ``.. image:: cow``.
+If the format is supported by |CONTEXT| the suffix can be
+neglected.
+
+The placement of images can be controlled via a set of optional
+arguments, each of which has to be specified on single line in
+``key: value`` style: ::
+
+ .. image:: cow
+ width: hsize
+ caption: A generic Dutch cow.
+
+This will place your image somewhere close to the spot where you
+defined it. (The placement parameter to ``placefigure`` will be
+set to ``here`` by default.)
+
+.. image:: cow
+ width: hsize
+ alt: A generic Dutch cow (*bos primigenius taurus*).
+
+The supported parameters are ``width``
+(alias: ``size``), ``caption`` and ``scale``.
+The *width* parameter accepts the values ``hsize``
+(alias: ``fit``, ``broad``) or ``normal``.
+Alternatively, the *scale* parameter allows for arbitrary
+manipulation of the desired magnification; it defaults to ``1``
+(unscaled).
+The value passed as *caption* parameter will be used in as the
+caption text of the image.

+
+=======================
+Substitution Directives
+=======================
+
+There are substitution directives for simple *replacing* and
+for insertion of |LUATEX|’s three languages: |mp|, Lua and,
+of course, |TEX|.
+
+.. |mp| replace:: \METAPOST
+
+Ordinary text replacement is done via the ``replace``
+substitution directive. E.g. in the main text you consistently
+use ``|replaceme|`` and have all its occurences substituted by
+``I wasn’t in the mood to write out this long sentence.``
+like in the next snippet:
+
+::
+
+ .. |replaceme| replace::
+ I wasn’t in the mood to write out this long sentence.
+
+The code insertions work similarly. You have to specify some
+phrase that gets substituted by the code you supply.
+E.g. this document accesses the fancy logos predefined in the
+|CONTEXT| core via substitutions: ::
+
+ .. |CONTEXT| ctx:: \CONTEXT
+ .. |LUATEX| ctx:: \LUATEX
+
+Etc. pp. The respective directive names are ``ctx``, ``mp`` and
+``lua``. In order to get a |circle| drawn on spot, you would
+define a Metapost substitution:
+
+::
+
+ .. |circle| mp::
+ fill fullcircle scaled(8) withcolor blue;
+
+================
+Special Features
+================
+Text Roles
+**********
+
+The default *role* for interpreted text is *emphasis*.
+
+The role marker provides explicit access to formatting commands.
+The formatting routine for inline literals can be called with the
+role marker :literal:`literal`, strong emphasis likewise is
+achieved via the role marker :literal:`strong_emphasis`.
+
+Other roles that lack an equivalent among inline markup are
+``bold``, :ss:`ss` (alias :literal:`sans_serif`),
+``uppercase``, ``lowercase`` and colors.
+Color roles begin with the string ``color_`` (the underscore is
+compulsive), followed by either the string ``rgb_`` or a
+`valid color name`__.
+An rgb vector is specified in decimal.
+Its values can be separated by either dashes or underscores.
+Thus, ``color_rgb_.3_.5_.8`` is a valid rgb expression, as is
+``color_rgb_0-1-0``.
+Unforturnately, the colon character ``:`` has to be escaped in
+color expressions, e.g. ``color_gray\:5``.
+
+__ http://wiki.contextgarden.net/Colors#Using_predefined_colors:_.5Csetupcolor
+
+For example, to give Mr. Neville Shunt’s work an apt
+typographic representation you can use these roles instead of
+the standard inline markup: ::
+
+ :color_rgb_.9_.2_.7:`Chuff`, chuff, :literal:`chuffwoooooch`,
+ woooooch! Sssssssss, sssssssss! :uppercase:`Diddledum`,
+ `diddledum`, diddlealum. :literal:`Toot`, toot. The train
+ :bold:`now` standing :color_gray\:5:`at` platform :ss:`eight,
+ tch`, tch, :color_rgb_0-1-0:`tch`,
+ :color_rgb_.5-.6-.2:`diddledum`, diddledum.
+ :lowercase:`Chuffff`, :strong_emphasis:`chuffffiTff`
+ eeeeeeeeeaaaaaaaaa :color_red:`Vooooommmmm`.
+
+which yields when passed through |rstcontext|:
+
+:color_rgb_.9_.2_.7:`Chuff`, chuff, :literal:`chuffwoooooch`,
+woooooch! Sssssssss, sssssssss! :uppercase:`Diddledum`,
+`diddledum`, diddlealum. :literal:`Toot`, toot. The train
+:bold:`now` standing :color_gray\:5:`at` platform :ss:`eight,
+tch`, tch, :color_rgb_0-1-0:`tch`,
+:color_rgb_.5-.6-.2:`diddledum`, diddledum. :lowercase:`Chuffff`,
+:strong_emphasis:`chuffffiTff` eeeeeeeeeaaaaaaaaa
+:color_red:`Vooooommmmm`.
+
+**************************
+Bibliography and Citations
+**************************
+
+.. caution::
+ Not much for now concerning the usage of Taco’s bib system.
+ It’s just that I use my own bibliography system and never
+ became sufficiently familiar with the standard |CONTEXT|
+ approach. *If you feel that the current support should be
+ improved then feel free to contact me!* I will need somebody
+ for testing.
+
+When |rstcontext| first encounters a citation (``[texbook]_``) it
+automatically looks up a bibliography in the working directory by
+the name of ``\jobname``. E.g. with a main file ``manual.tex``
+bibtex will use the database called ``manual.bib``. Symlinking
+your bibliography file in the local tree should suffice and you
+can keep whatever directory structure you prefer. (Speaking for
+myself, bib data usually resides in its own subdirectory, so I’d
+use symlinks, too.)
+
+===================
+About this software
+===================
+
+The docutils_ provide means to translate the extra-convenient
+markup language |rst| into various formats like PDF, HTML and
+|LATEX|, unfortunately omitting the One True Macro System:
+|CONTEXT|.
+
+As far as I am aware of it, there is some support for |rst| in
+Pandoc_ but as it relies on a rather large set of dependencies it
+proved very difficult (too difficult for me) to install on my
+favourite distribution.
+From the `interactive demo`__ I gather that support for |rst|’s
+language features is not very extensive and the result did not
+even come with proper setups.
+Additionally, it’s written in a language I am not familiar with
+and that does not make use of one the most awesome features of
+all the the extended capabilities |LUATEX| provides: the Lua
+interpreter.
+
+For quite some time I was thinking about how to implement an
+|rst| parser in |LUATEX|, until some discussion__ emerged on the
+|CONTEXT| mailing list that indicates a broader interest in
+convenient markup languages across the community.
+As the alternatives mentioned above don’t meet the expectations
+of a normal |CONTEXT| user, the initial step to write
+|rstcontext| was done.
+Handling most of the corner cases and usability features of |rst|
+proved in the end not nearly as easy as I imagined.
+
+__ http://johnmacfarlane.net/pandoc/try
+__ http://archive.contextgarden.net/message/20100814.051917.28caafcd.en.html
+
+.. caution::
+ |rstcontext| is experimental software and neither feature
+ complete nor thoroughly commented. Keep this in mind before you
+ start using it. Anything might still be subject to change, so
+ expect breakage *in case you start relying on exceptional
+ behaviour* (read: bugs) that does not conform to the |rst|
+ specification. Consider filing a bug report instead and wait for
+ me (the maintainer) to fix it, because regardless of how much
+ testing I do myself I alway run into the weirdest issues only
+ during the actual deployment of the software. Thus, if you notice
+ that |rstcontext| does not adhere to the outline_ of |rst|
+ according to the Docutils documentation, very likely you have
+ discovered a corner case I was not aware of.
