17%D This module has been adapted to \MKIV\ by Hans Hagen so if things go wrong,
18%D he is to blame. The changes concern references and lists but teh rendering
19%D itself is unchanged. Future versions might provide variants as we have plans
20%D for an upgrade.
21%D
22%D We use a still somewhat experimental extension to the list
23%D mechanism. Eventually the bibtex module will use the bibl loader
24%D and access the data by means of lpath expressions. In that case we
25%D don't need to process the bibliography but still need to track
26%D usage as done here.
27%D
28%D A bit ongoing: make more local macros prefixed with bib, i.e. the bib
29%D namespace is reserved.

39%D The original was developed independantly by Taco Hoekwater while still working for Kluwer
40%D Academic publishers (it still used the dutch interface then). Development continued after
41%D he left Kluwer, and in Januari 2005, the then already internationalized file was merged
42%D with the core distribution by Hans Hagen. The current version is once again by Taco.

170%D \item All constants, variables, message etc.\ are now in the core.
171%D \item Added key: \type {method} (when \type {global}, previous shown entries are

234%D Unfortunately, \BIBTEX\ is not the best configurable program
235%D around. The names of the commands it parses as well as the \type{.aux}
236%D extension to the file name are both hardwired.
237%D
238%D This means \CONTEXT\ has to write a \LATEX-style auxiliary file, yuk!
239%D The good news is that it can be rather short. We'll just ask
240%D \BIBTEX\ to output the entire database(s) into the \type{bbl} file.
241%D
242%D The \type{\bibstyle} command controls how the \type{bbl} file will
243%D be sorted. The possibilities are:
244%D
245%D \startitemize[packed]
246%D \item by author (+year, title): cont-au.bst
247%D \item by title  (+author, year): cont-ti.bst

369%D This will be the first command in (\BIBTEX-generated) \type{bbl}

372%D is the total number of entries that will follow in this
373%D file.
374%D
375%D Both values are only needed for the label calculation
376%D if `autohang' is `true', so by default the command is
377%D not even needed, and therefore I saw no need to give

414%D one of the \type{@@pb@} data entries. \type{bibinsert#1} then has
415%D three arguments: \type{#1} are commands to be executed before the

417%D \type{#3} are commands to be executed if the data is not found.

470%D The commands \type{\artauthor}, \type{\author} and

472%D Their argument lists have this form:
473%D
474%D \type{\author[junior]{firstnames}[inits]{von}{surname}}
475%D
476%D (bracketed stuff is optional)
477%D
478%D And not only that, but there also might be more than one of each of
479%D these commands. This is why a special command is needed to insert
480%D them, as well as one extra counter for each command.
481
482% todo: instead of \getvalue{bla@num} in specs we should do
483% \bibentrynum{bla} so that we can create a better namespace
484
485%D All of these \type{\expandafter}'s and \type{\csnames} make this code
486%D look far more complex than it really is. For example, the argument
487%D \type{author} defines the macro \type{\bib@author} to do two
488%D things: increment the counter \type{\author@num} (let's say to 2)
489%D and next store it's arguments in the macro \type{\@@pb@author2}.

646%D We are coming to the end of this module, to the macros that
647%D do typesetting and read the \type{bbl} file.
648
649%D Just a \type{\dosingleempty} is the most friendly
650%D of doing this: there need not even be an argument
651%D to \type{\startpublication}. Of course, then there
652%D is no key either, and it had better be an
653%D article (otherwise the layout will be all screwed up).
654%D
655%D Only specifying the key in the argument is also
656%D legal. In storing this stuff into macros, some trickery with
657%D token registers is needed to fix the expansion problems. Even so,
658%D this appears to not always be 100\% safe, so people are
659%D urgently advised to use \ETEX\ instead of traditional \TEX.
660%D
661%D In \ETEX, all expansion problems are conveniently solved by
662%D the primitive \type{\protected}. To put that another way:
663%D
664%D It's not a bug in this module if it does not appear in \ETEX!

1028%D If compression of \type{\cite}'s argument expansion is on,
1029%D the macros that deal with authors and years call this internal
1030%D command to do the actual typesetting.
1031%D
1032%D Two entries with same author but with different years may
1033%D be condensed into ``Author (year1,year2)''. This is about the
1034%D only optimization that makes sense for the (author,year)
1035%D style of citations (years within one author have to be unique
1036%D anyway so no need to test for that, and ``Author1, Author2 (year)''
1037%D creates more confusion than it does good).
1038%D
1039%D In the code below,
1040%D the macro \type{\thebibauthors} holds the names of the alternative
1041%D author info fields for the current list. This is a commalist,
1042%D and \type{\thebibyears} holds the (collection of) year(s) that go with
1043%D this author (possibly as a nested commalist).
1044%D
1045%D There had better be an author for all cases, but there
1046%D does not have to be year info always. \type{\thebibyears} is
1047%D pre-initialized because this makes the insertion macros simpler.
