+This is JOURABBR.BIB, a BibTeX database file for the `adaptable' style

+First of all we use a PREAMBLE command to put some stuff at the beginning

+defined and set appropriate, that can be used to distinguish between german
+and all other languages; the same technique may be adapted to other
+languages as well. The \sortby command is suggested in the BibTeX manual
+(where it is called \noopsort) and is helpful to force sorting of certain
+entries.

+This is the BibTeX `adaptable' family of style files, version 1.10 as of
+April 1992, derived from the `plain' family by Hans-Hermann Bode. It allows
+setting of certain style parameters and definition of phrases without
+changing the style files, thus a multiple-language support is provided and
+the user may adapt the bibliography layout to his or her requirements within
+some limits.
+
+Send suggestions and bug reports to HHBODE@DOSUNI1.BITNET.

+./a4c.tex	definition of length parameters for DIN-A4 paper, WEB version
+./docmac.doc	documentation of documentation macros (indeed!)
+./docmac.tex	documentation macros
+
+*** Installation -------------------------------------------------------------
+
+To get a working adaptable-styles system you have to copy the following
+files into special directories.
+
+-- Copy all *.bst files into a directory where BibTeX looks for style files.
+This will usually be a directory in the TEXINPUT(S) path, i.e., in the same
+path where TeX looks for its input files.
+
+-- Copy apreambl.tex into a directory where TeX looks for its input files,
+see above.
+
+-- Copy all *.bib files into a directory where BibTeX looks for bibliography
+databases. This will usually be a directory in the BIBINPUT(S) path.
+
+Optionally, you may copy a4c.* and docmac.tex into a directory in the
+TEXINPUT(S) path. These files will be needed when printing the
+documentation; they may be useful, however, for other applications as well.
+
+*** Printing the documentation -----------------------------------------------
+
+The main documentation is a LaTeX source in abstdok.tex. Run LaTeX on this
+file twice (for resolving cross references) and make sure that apreambl.tex,
+abstdok.bbl, and a4c.sty can be loaded. In addition, the file german.sty is
+required; it is not included in this distribution, since you should be able
+to get it from every good TeX server (at least in Germany). The style file
+a4c.sty will set up length parameters so that the document will come out
+centered with margins of 2 cm on each side of a DIN-A4 sheet; if this
+doesn't fit to your paper format, you may want to edit this file first.
+Unfortunately, this documentation is written in German (which is due to the
+fact that European people sometimes get nostalgic and switch to their native
+language); if you feel the need to translate this into English, don't
+hesitate to do so (and send me the file, so I can include it into the next
+distribution).
+
+The definition of the adaptable parameters is discussed in apreambl.doc (in
+English, yes). Run this through TeX (not LaTeX, and don't forget the .doc
+extension!) and make sure that a4c.tex and docmac.tex can be loaded. The
+file a4c.tex corresponds to a4c.sty above, and docmac.tex contains macros
+for typesetting a WEB-style documentation. In fact, apreambl.tex is derived
+from apreambl.doc by means of Joachim Schrod's MAKEPROG system, which is a
+general documentation tool much similar to the WEB system of structured
+documentation; docmac.tex is an enhancement of MAKEPROG's macro package
+progdoc.tex which makes the documentation layout more ``WEB-like''. If you
+want to change some of the adaptable parameters, the best way to do it is to
+get MAKEPROG (it should be available from the same source as the adaptable
+style files) and write a changefile to apreambl.doc. Then there is a good
+chance that you can apply your changes to future versions of this
+distribution without major modifications. Moreover, you can use MAKEPROG and
+docmac.tex for your own developments, it's worth a try! (In this case you may
+want to look at docmac's documentation: just run TeX on docmac.doc and make
+sure that docmac.tex is loadable.)
+
+Further documentation is provided in plain-text form in the files
+jourabbr.bib, jourfull.bib, and acompat.bib. You may want to edit the first
+two of them to add more journal names or other general stuff that should be
+defined at the beginning of your bibliographies.
+
+*** Usage hints (VERY brief) -------------------------------------------------
+
+It is assumed that you are familiar with the BibTeX philosophy and the
+standard style files, so here is a short description what you have to do in
+addition to use the adaptable styles.
+
+Choose one of the styles aplain, aabbrv, aunsrt, aalpha, anotit, or aunsnot
+(the first four are the adaptable versions of the corresponding standard
+styles, anotit is like aabbrv but omits titles of articles and some other
+redundant information, aunsnot is like anotit but doesn't sort the
+bibliography) and put a statement like
+
+  \bibliographystyle{aplain}
+
+somewhere into your document.
+
+Make sure that apreambl.tex is input before the \bibliography command is
+executed. The easiest way to do so is to include jourfull or jourabbr at the
+beginning of your \bibliography list. The file apreambl.tex carries out all
+parameter settings and switches between `full' and `abbreviated' as well as
+English and German versions of phrases automatically. The version it selects
+depends on the bibliography style and on the fact whether german.sty is
+loaded or not. The databases jourfull.bib and jourabbr.bib will load
+apreambl.tex and, furthermore, will define all strings that are lacking in
+the adaptable styles in comparison with the standard styles; hence, with
+this files you can use your old databases without changes, and---as
+mentioned above---this is the right place to add your own general
+definitions. So, a typical \bibliography command should look like
+
+  \bibliography{jourfull,user1,user2,user3}
+
+where user1, user2, and user3 are your private bibliography databases.
+
+If you ever feel the need to use one of the standard styles again, your
+databases---due to the use of special features of the adaptable styles---may
+not be compatible any more. The compatibility can be restored by means of
+acompat.bib, which defines all additional strings of the adaptable styles
+and should be included at the very beginning of the \bibliography list, e.g.,
+
+  \bibliography{acompat,jourfull,user1,user2,user3}\bibliographystyle{plain}
+
+Of course, acompat is not required for use with the adaptable styles alone.
+
+*** Correction ---------------------------------------------------------------
+
+In parts of the documentation, the files apreambl.doc and apreambl.tex are
+referred to as apreamble.doc and apreamble.tex. The names were shortened to
+avoid difficulties with some operating systems with low-length file names.

+
+Mit {\BibTeX} steht dem \LaTeX- wie dem plain-\TeX-Anwender ein
+au"serordentlich leistungsf"ahiges Werkzeug zur Verf"ugung, um
+Bibliographien zu Artikeln, Berichten, B"uchern und {\em literate
+programs\/} zu erstellen. Mu"ste man fr"uher m"uhsam alle zitierten
+Literaturstellen zusammensuchen, alle Angaben -- oft immer wieder dieselben
+-- per Hand eintippen (m"oglichst, ohne Fehler bei Seitenangaben,
+Bandnummern, Jahreszahlen usw.~zu machen) und sich schlie"slich auch noch um
+Layout-Fragen k"ummern, so beschr"ankt sich diese Arbeit mit {\BibTeX} auf
+die einmalige Eingabe der bibliographischen Informationen in eine
+Literaturdatenbank und das Aufrufen von \verb|\cite|-Kommandos mit einem
+Schl"ussel f"ur das zu zitierende Werk. {\BibTeX} stellt dann die
+Literaturliste zusammen und sorgt auch f"ur ein konsistentes Aussehen
+derselben.
+
+{\BibTeX} ist "`offizieller"' Bestandteil des \LaTeX-Makropakets und von
+Lamport in~\cite{latex} beschrieben, eine deutsche Fassung findet man etwa
+bei Kopka~\cite{kopka-einf}. Dar"uberhinaus erlaubt das zur
+Standard-\BibTeX-Distribution geh"orige Makropaket {\tt btxmac.tex} auch die
+Verwendung unter plain-\TeX\, und zwar mit der gleichen
+Benutzerschnittstelle (dieses Makropaket ist auch mit dem {\tt WEB}-System
+f"ur strukturierte Dokumentation kompatibel, so da"s \BibTeX\ auch beim {\em
+literate programming\/} eingesetzt werden kann). Oren Patashnik, der Autor
+des \BibTeX-Programms, legt mit~\cite{bibtex-doc} ein Manual f"ur
+\BibTeX-Benutzer vor, das im Gegensatz zu den zuvor genannten Stellen die
+jeweils aktuelle Version dokumentiert und das in einer Datei {\tt
+btxdoc.tex} jeder \BibTeX-Implementation beigegeben sein sollte. Die
+Kenntnis wenigstens einer der angegebenen Quellen wird hier vorausgesetzt
+und nicht weiter auf allgemeine Grundlagen der Benutzung von {\BibTeX}
+eingegangen.
+
+Das Schlu"skapitel von Patashniks Manual -- herausgegeben als separates
+Dokument~\cite{bibtex-hak} -- beschreibt M"oglichkeiten der Erzeugung von
+Style-Files, die das Layout der Bibliographie bestimmen. Vier solcher
+Style-Files ({\tt plain}, {\tt unsrt}, {\tt alpha} und {\tt abbrv}) geh"oren
+zum Standardumfang von {\BibTeX}. Weitere Styles -- wie {\tt siam}, {\tt
+ieeetr} oder {\tt apalike} -- wurden von Patashnik u.\,a.~erstellt, in
+erster Linie, um den Anforderungen bestimmter Zeitschriftenherausgeber zu
+entsprechen. Die Erzeugung von solchen Styles, auch wenn es nur um relativ
+geringf"ugige Ab"anderungen vorhandener Stile geht, ist allerdings ein recht
+m"uhsamer Vorgang (man mu"s Programme in einer Spezialsprache mit
+Postfixnotation schreiben), der die meisten {\BibTeX}-Anwender "uberfordern
+d"urfte. Aus diesem Grund entstand die {\em adaptable family}, die eine
+einfache Anpassung an pers"onliche oder fremde Vorstellungen erlaubt.
+
+\section*{Die Styles} %-------------------------------------------------------
+

+    \hline\hline
+  \end{tabular}
+\end{table}
+
+Das grunds"atzliche Aussehen der Bibliographie wird auch bei den anpa"sbaren
+Versionen durch den jeweiligen, im \verb|\bibliographystyle| der \TeX-Quelle
+gew"ahlten Stil festgelegt. Dieser bestimmt im wesentlichen, welche
+Informationen "uberhaupt auszugeben sind und in welcher Reihenfolge diese
+angeordnet werden sollen; dar"uber hinaus sind f"ur jeden Stil eine Reihe von
+festen, unver"anderlichen Merkmalen vorgegeben, die in Tabelle~\ref{tab:stile}
+f"ur die sechs Stile der {\em adaptable family\/} zusammengefa"st sind.
+
+Alle Stile bis auf {\tt aalpha} erzeugen numerische Marken zur Kennzeichnung
+der Zitate ("`[1]"', "`[2]"' usw.), w"ahrend {\tt aalpha} die Marken
+alphanumerisch, i.\,allg.~aus K"urzeln f"ur die Autorennamen und
+Erscheinungsjahr, zusammensetzt (z.\,B.~"`[knu73]"'). Bei {\tt aunsrt} und
+{\tt aunsnot} erscheint die Bibliographie in der Reihenfolge der Zitate, bei
+den anderen Stilen wird sie nach Autorennamen, Erscheinungsjahren
+usw.~sortiert. Das Attribut "`initial"' zeigt an, ob die Vornamen der
+Autoren abgek"urzt werden oder nicht; das erstere ist der Fall f"ur {\tt
+aabbrv}, {\tt anotit} und {\tt aunsnot}, die zudem im Unterschied zu den
+"ubrigen Stilen als "`kurz"' gekennzeichnet sind (die Bedeutung dieses
+Attributs wird im n"achsten Abschnitt erkl"art). Alle Stile setzen
+Gro"sbuchstaben, die in Titeln von Zeitschriftenartikeln -- sofern diese
+"uberhaupt ausgegeben werden -- vorkommen und nicht am Satzanfang stehen, in
+Kleinschreibung um (Attribut "`klein"'); dies ist zwar f"ur deutsche Titel
+nicht geeignet, l"a"st sich aber leicht unterdr"ucken (s.~die Er"orterung am
+Ende dieses Artikels). Schlie"slich zeichnen sich die Stile {\tt anotit} und
+{\tt aunsnot} dadurch aus, da"s die Titel von Zeitschriftenartikeln
+unterdr"uckt werden, wie es etwa in der physikalischen Literatur
+durchg"angig "ublich ist.
+
+Insgesamt entsprechen die Stile {\tt aplain}, {\tt aunsrt}, {\tt aalpha} und
+{\tt aabbrv} -- wie auch aus der Namensgebung hervorgeht -- den vier
+Standardstilen von \BibTeX\ (Patashniks {\em plain family\/}), w"ahrend {\tt
+anotit} und {\tt aunsnot} hinzugef"ugt wurden, um eine L"ucke zu schlie"sen.
+
+\section*{Anpassung von Layout und F"ullw"ortern} %---------------------------
+
+Die Anpassung der {\tt a}-Stile erfolgt durch Definition bestimmter
+\TeX-Makros; andererseits funktionieren die Stile nicht, wenn diese Makros
+undefiniert sind. Die Definition geschieht zweckm"a"sigerweise "uber ein
+\verb|@PREAMBLE|-Kommando, das sich in einer der bibliographischen
+Datenbanken befindet (vgl.~das n"achste Kapitel). Die {\tt a}-Styles
+definieren einen Schalter \verb|abfull|, der in Abh"angigkeit davon, ob es
+sich um einen "`Kurzstil"' handelt oder nicht (s.~Tab.~\ref{tab:stile}), den
+Wert \verb|false| oder \verb|true| bekommt. So k"onnen sich die Makros
+automatisch darauf einstellen, F"ullw"orter abzuk"urzen oder voll
+auszuschreiben.
+
+\begin{table}\small\centering
+  \caption{\sf Zusammenstellung der verwendeten Makros.\strut}
+  \label{tab:makros}
+  \medskip
+  \begin{tabular}{lp{8cm}}
+    \hline\hline
+    Makroname         & Bedeutung\\
+    \hline
+    \verb|\abtype|    & Definiert die Schriftauszeichnung einzelner Felder
+                        eines Bibliographieeintrags.\\
+    \verb|\abphrase|  & Legt die F"ullw"orter fest.\\
+    \verb|\abmonth|   & Enth"alt die Monatsnamen.\\
+    \verb|\abedition| & Stellt Bezeichnungen f"ur Auflagen eines Buches zur
+                        Verf"ugung ("`Erste"', "`Zweite"', "`Dritte"' usw.).\\
+    \verb|\abchapter| & Gibt Namen f"ur bestimmte Segmente eines
+                        Schriftst"ucks zur"uck ("`Abschnitt"', "`Absatz"',
+                        "`Anhang"' oder "`Teil"').\\
+    \hline\hline
+  \end{tabular}
+\end{table}
+
+Die fraglichen Makros sind in Tab.~\ref{tab:makros} zusammengestellt. Alle
+Makronamen beginnen mit {\tt ab}. W"ahrend \verb|\abtype| f"ur die
+Schriftauszeichnung verantworlich ist, haben alle anderen Makros mit
+F"ullw"ortern zu tun und erlauben sprachspezifische Anpassungen sowie
+Unterscheidung zwischen "`Kurz-"' und "`Vollstilen"'. Es folgen detaillierte
+Beschreibungen der Makros mit ihren Parametern.
+
+\subsection*{{\tt abtype}}
+
+\begin{table}\small\centering
+  \caption{\sf Der erste Parameter von {\tt abtype}.\strut}\label{tab:abtype}
+  \medskip
+  \begin{tabular}{rp{5cm}}
+    \hline\hline
+    Code & Bedeutung\\
+    \hline
+      0  & Namen von Autoren und Editoren\\
+      1  & Titel von B"uchern und Reihen\\
+      2  & Zeitschriftentitel\\
+      3  & Bandnummern von Zeitschriften\\
+      4  & Heftnummern von Zeitschriften\\
+      5  & Datumsangaben\\
+    \hline\hline
+  \end{tabular}
+\end{table}
+
+Die Layoutsteuerung wird "uber das Makro \verb|\abtype| vorgenommen. Die {\tt
+a}-Stile schreiben die meisten Felder eines Eintrags indirekt "uber einen
+Aufruf von \verb|\abtype| in die Bibliographie, wobei zwei Argumente
+"ubergeben werden: eine Codenummer f"ur die Art des Feldes und der in das
+Feld einzutragende Text. Dieser kann dann vom Makro beliebig formatiert
+zur"uckgegeben werden.  Die Codewerte f"ur den ersten Parameter von
+\verb|\abtype| findet man in Tab.~\ref{tab:abtype}.
+
+Durch eine Definition der Form
+\begin{verbatim}
+\def\abtype##1##2{%
+\ifcase##1{\sc##2}\or"`##2"'\or{\em##2\/}\or{\bf##2}\or%
+(##2)\or(##2)\else##2\fi}}
+\end{verbatim}
+also erreichte man beispielweise, da"s Autorennamen in {\sc Kapit"alchen},
+Buchtitel in "`Anf"uhrungszeichen"' und Zeitschriftentitel {\em kursiv\/}
+gesetzt werden und da"s Bandnummern von Zeitschriften {\bf fett} erscheinen,
+w"ahrend Heftnummern ebenso wie Datumsangaben geklammert werden.
+Vorsichtshalber wurde noch eine \verb|\else|-Klausel angef"ugt, die bewirkt,
+da"s bei Aufruf des Makros mit einem undefinierten Codewert das zweite
+Argument unformatiert zur"uckgegeben wird (f"ur die Original-{\tt a}-Stile
+w"are dies nicht erforderlich).
+
+\subsection*{{\tt abphrase}}
+
+\begin{table}\small\centering
+  \caption{\sf Der Parameter von {\tt abphrase}.\strut}\label{tab:abphrase}
+  \medskip
+  \begin{tabular}{rp{9.5cm}}
+    \hline\hline
+    Code & Bedeutung\\
+    \hline
+      0  & Bindewort zwischen zwei oder vor dem letzten Namen einer Liste
+           ("`und"')\\
+      1  & Satzzeichen vor dem letzten Bindewort einer Namensliste (im
+           Deutschen nichts, im Englischen ein Komma)\\
+      2  & Ersatz f"ur Namen von Mitautoren und Mitherausgebern ("`u.\,a."' oder
+           "`et~al."')\\
+      3  & Bezeichnung f"ur mehrere Herausgeber (z.\,B.~"`Editoren"')\\
+      4  & Bezeichnung f"ur einen Herausgeber ("`Editor"')\\
+      5  & Wort nach der Bandnummer einer Reihe oder Kreuzreferenz ("`aus"')\\
+      6  & Wort nach der Ausgabennummer einer Reihe ("`in"')\\
+      7  & Wort vor Querverweisen auf B"ucher, Artikel usw.~("`In"')\\
+      8  & Wort vor einer Bandnummer mitten im Satz ("`volume"' auf
+           Englisch, aber "`Band"' auf Deutsch)\\
+      9  & dto.~am Satzanfang ("`Volume"' bzw.~erneut "`Band"')\\
+     10  & Wort vor einer Reihennummer mitten im Satz ("`Nummer"')\\
+     11  & dto. am Satzanfang (im Deutschen dasselbe)\\
+     12  & Wort hinter einer Auf"|lagennummer ("`Auf"|lage"')\\
+     13  & Wort vor mehreren Seitennummern ("`Seiten"')\\
+     14  & Wort vor einer einzelnen Seitennummer ("`Seite"')\\
+     15  & Wort vor einer Kapitelnummer ("`Kapitel"')\\
+     16  & Bezeichnung f"ur einen Forschungsbericht ("`Technical Report"')\\
+     17  & Bezeichnung f"ur eine Diplomarbeit ("`Master's thesis"')\\
+     18  & Bezeichnung f"ur eine Doktorarbeit ("`PhD Thesis"')\\
+    \hline\hline
+  \end{tabular}
+\end{table}
+
+Der gr"o"ste Teil der F"ullw"orter wird durch \verb|\abphrase| abgedeckt.
+Das Makro hat einen Parameter, der wieder eine Codenummer darstellt.
+Die vorkommenden Werte zeigt Tab.~\ref{tab:abphrase}.
+
+Ein Beispiel f"ur eine geeignete Definition von \verb|\abphrase| mit
+ausgeschriebenen, deutschen F"ullw"ortern w"are:
+\begin{verbatim}
+\def\abphrase##1{%
+\ifcase##1{ und }\or{}\or{ und andere}\or%
+{ (Herausgeber)}\or{ (Herausgeber)}\or%
+{ aus }\or{ in }\or{In }\or%
+{Band}\or{Band}\or{Nummer}\or{Nummer}\or%
+{ Auf"|lage}\or{Seiten}\or{Seite}\or{Kapitel}\or%
+{Bericht}\or{Diplomarbeit}\or{Dissertation}\fi}
+\end{verbatim}
+
+\subsection*{{\tt abmonth}}
+
+Einfacher als die vorangegangenen Makros ist \verb|\abmonth|: Es wird mit
+einer Zahl zwischen 1~und~12 als Argument aufgerufen und sollte die
+Bezeichnung f"ur den entsprechenden Monat zur"uckgeben; also etwa
+\begin{verbatim}
+\def\abmonth##1{\ifcase##1\or Januar\or Februar\or M"arz\or
+  April\or Mai\or Juni\or Juli\or August\or September\or
+  Oktober\or November\or Dezember\fi}
+\end{verbatim}
+Man beachte, da"s vor \verb|Januar| bereits ein \verb|\or| stehen mu"s, da
+dieser Monat den Code~1 hat und nicht~0. Desweiteren gilt, da"s die
+Definition von \verb|\abmonth| nur dann einen Effekt hat, wenn in den
+Bibliographiedatenbanken von den vordefinierten Strings {\tt jan}, {\tt
+feb}, \dots, {\tt dec} Gebrauch gemacht wird -- es sei denn, man ruft das
+Makro direkt auf, wovon man jedoch im Hinblick auf m"ogliche
+Kompatibilit"atsprobleme mit anderen Styles oder zuk"unftigen Versionen der
+anpa"sbaren Stile Abstand nehmen sollte.
+
+\subsection*{{\tt abedition}}
+
+Ein weiteres Makro mit einem numerischen Wert als Parameter ist
+\verb|\abedition|. Die "ubergebene Zahl bezeichnet eine Auf"|lagennummer und
+es sollte ein entsprechender String zur"uckgegeben werden, z.\,B.:
+\begin{verbatim}
+\def\abedition##1{\ifcase##1\or Erste\or Zweite\or Dritte\or
+  Vierte\or F"unfte\or Sechste\or Siebte\or Achte\or
+  Neunte\or Zehnte\else?\fi}
+\end{verbatim}
+In den anpa"sbaren Stilen existieren vordefinierte Strings {\tt first}, {\tt
+second}, \dots, {\tt tenth}, die man aus den gleichen Gr"unden wie oben f"ur
+das {\tt EDITION}-Feld der Bibliographieeintr"age verwenden sollte. Ein
+Problem ergibt sich, wenn eine Auflagennummer gr"o"ser als~10 ben"otigt
+wird; in diesem Fall sollte man das Makro entsprechend erweitern und
+zus"atzliche Strings durch {\tt @STRING}-Kommandos definieren.
+
+\subsection*{{\tt abchapter}}
+
+Schlie"slich ist noch ein Makro mit einem Code zwischen 0~und~3 f"ur
+Bezeichnungen verschiedener Segmente eines Dokuments zu definieren. Die
+Bedeutung ergibt sich unmittelbar aus dem Beispiel
+\begin{verbatim}
+\def\abchapter##1{\ifcase##1Abschnitt\or Absatz\or
+Anhang\or Teil\fi}
+\end{verbatim}
+Auch f"ur den Aufruf dieses Makros gibt es vordefinierte Strings, die man in
+den Datenbanken tunlichst benutzen sollte; sie hei"sen {\tt section}, {\tt
+paragraph}, {\tt appendix} und {\tt part} und sind gedacht f"ur den Einsatz
+im {\tt TYPE}-Feld mancher Eintr"age, mit welchem sich das {\tt
+CHAPTER}-Feld umwidmen l"a"st.
+
+\section*{Benutzungshinweise} %-----------------------------------------------
+
+Zum Gl"uck braucht man die im letzten Kapitel vorgestellten Makros nicht
+selbst einzugeben, sie sind vielmehr bereits in der Datei {\tt
+apreamble.tex} enthalten, die zum Lieferumfang des Pakets geh"ort. Sie
+stellt in Abh"angigkeit vom \verb|abfull|-Schalter ausgeschriebene oder
+abgek"urzte F"ullw"orter zur Verf"ugung.  Mehr noch, diese Datei enth"alt
+neben den deutschen F"ullw"ortern auch "aquivalente Definitionen in
+englischer Sprache. Die Auswahl zwischen den beiden Sprachversionen wird
+automatisch getroffen, und zwar nach folgenden Kriterien:
+\begin{itemize}
+  \item Ist das Makropaket {\tt german.sty} {\em nicht\/} geladen, wird die
+englische Version genommen.
+  \item Wird dagegen festgestellt, da"s {\tt german.sty} eingelesen wurde,
+h"angt die Sprachauswahl vom eingestellten \verb|\language|-Wert ab:
+  \begin{itemize}
+    \item Ist dieser gleich \verb|\german| oder \verb|\austrian|, wird die
+  deutsche Version gew"ahlt.
+    \item In allen anderen F"allen ist es wieder die englische.
+  \end{itemize}
+\end{itemize}
+Auf diese Weise sollten zumindest alle diejenigen zufriedengestellt sein,
+die entweder nur englische Dokumente verfassen oder unter Benutzung von {\tt
+german.sty} sowohl englische als auch deutsche Texte schreiben. Nat"urlich
+steht es jedem frei, {\tt apreamble.tex} um zus"atzliche Sprachen zu
+erweitern oder die mittels \verb|\abtype| vorgenommenen Formatierungen nach
+eigenem Gutd"unken abzu"andern.
+
+Damit der oben vorgestellte Mechanismus zur Sprachauswahl funktioniert, mu"s
+die Datei {\tt german.sty} -- wenn "uberhaupt -- {\em vor\/} {\tt
+apreamble.tex} eingelesen werden. Dies sollte im Zusammenhang mit \LaTeX\
+kein Problem darstellen, da \verb|german| f"ur gew"ohnlich als
+Dokumentstiloption verwendet wird. Wie oben erw"ahnt l"a"st sich \BibTeX\
+aber auch mit plain-\TeX\ nutzen, wenn das Makropaket {\tt btxmac.tex}
+eingebunden wird; hier ist dann sicherzustellen, da"s der Befehl
+\verb|\input german.sty| vor \verb|\input apreamble| (bzw., wie im n"achsten
+Absatz erl"autert, vor \verb|\bibliography{...}|) erscheint. Alle zur {\em
+adaptable family\/} geh"origen Makros sind "ubrigens so abgefa"st, da"s sie
+sowohl mit \LaTeX\ als auch mit plain-\TeX\ funktionieren; insbesondere
+vertragen sie sich auch mit dem {\tt WEB}-System f"ur strukturierte
+Dokumentation.
+
+Weiterhin ist es nat"urlich erforderlich, da"s {\tt apreamble.tex} vor der
+eigentlichen Bibliographie eingelesen wird; auch daf"ur steht eine implizite
+L"osung bereit. Es ist ohnehin vorteilhaft, wenn man eine oder mehrere {\tt
+bib}-Dateien mit allgemeinen Definitionen (haupts"achlich
+\verb|@STRING|-Kommandos) anlegt und diese stets am Anfang der
+\verb|\bibliography|-Liste aufz"ahlt. Zum Lieferumfang der {\em adaptable
+family\/} geh"oren zwei solche Dateien, {\tt jourfull.bib} und {\tt
+jourabbr.bib}, die Namen f"ur Zeitschriften -- einmal in ausgeschriebener
+und zum anderen in abgek"urzter Form -- definieren, und zwar gerade die,
+welche in den Standard-Bibliographiestilen (der {\em plain family\/})
+bereits vordefiniert sind\footnote{Der Autor der {\em adaptable family\/}
+war der Meinung, da"s die Auswahl dieser Zeitschriften zu speziell auf ein
+Fach bezogen ist, und hat die Definitionen daher in seinen Stildateien
+weggelassen. Unter Benutzung dieser beiden Dateien ist jedoch die volle
+Kompatibilit"at von Datenbanken, die f"ur die Standardstile erstellt wurden,
+zu den anpa"sbaren Stilen gew"ahrleistet.}. Beide Dateien laden {\tt
+apreamble.tex} automatisch am Anfang der Bibliographie. Alles, was man zur
+Nutzung der anpa"sbaren Stile -- abgesehen vom eventuellen Laden von {\tt
+btxmac} -- innerhalb eines Dokuments zu tun hat, beschr"ankt sich somit auf
+zwei Kommandos, die typischerweise so aussehen:
+\begin{verbatim}
+\bibliography{jourfull,user1,user2,user3}\bibliographystyle{aplain}
+\end{verbatim}
+Dabei sind \verb|user1|, \verb|user2| und \verb|user3| irgendwelche
+Benutzerdatenbanken, \verb|jourfull| kann nat"urlich auch durch
+\verb|jourabbr| ersetzt werden (mu"s aber immer am Anfang der Liste stehen!)
+und statt \verb|aplain| kann selbstverst"andlich ein beliebiger anderer
+anpa"sbarer Stil verwendet werden. Es ist zu betonen, da"s die Auswahl
+"`ausgeschriebene oder abgek"urzte Zeitschriftennamen"' nicht vom
+Bibliographiestil bestimmt wird, sondern durch Angabe von \verb|jourfull|
+oder \verb|jourabbr| erfolgt.
+
+Au"serdem definieren die beiden Dateien {\tt jourfull.bib} und {\tt
+jourabbr.bib} Strings namens \verb|ifger|, \verb|else| und \verb|fi|, die es
+auf einfache Weise erm"oglichen, innerhalb der Datenbanken bei einzelnen
+Feldern von der automatischen Sprachauswahl zu profitieren. Beispielsweise
+k"onnte damit das \verb|NOTE|-Feld eines Eintrags etwa folgendes enthalten:
+\begin{verbatim}
+ifger # "Wird demn{\"a}chst erscheinen." # else # "To be published." # fi
+\end{verbatim}
+Wie man unschwer erkennt, handelt es sich um eine bedingte Anweisung:
+\verb|ifger| sorgt daf"ur, da"s der nachstehende Text ausgegeben wird, wenn
+die automatische Sprachauswahl sich f"ur "`deutsch"' entschieden hat,
+\verb|else| leitet die Alternative f"ur den gegenteiligen Fall ein und
+\verb|fi| schlie"st die ganze Konstruktion ab. Der Operator~\verb|#|
+verkettet die einzelnen Teile zu einem von \TeX\ interpretierbaren
+Gesamtstring.
+
+Gelegentlich mag es vorkommen, da"s man die neuen, auf die {\em adaptable
+family\/} zugeschnittenen Datenbanken mit einem der Standardstile verwenden
+will. Dies st"o"st auf Schwierigkeiten, da die anpa"sbaren Stile einige
+zus"atzliche Strings definieren, von denen man sicherlich Gebrauch gemacht
+hat (genauer: machen sollte). Es steht aber eine Datei {\tt acompat.bib} zur
+Verf"ugung, die alle zus"atzlichen Strings nachtr"aglich definiert. Bindet
+man diese noch vor {\tt jourfull.bib} oder {\tt jourabbr.bib} (die man f"ur
+die oben beschriebenen Mechanismen weiterhin braucht) in die
+\verb|\bibliography|-Liste ein, so steht einer Nutzung der Standardstile
+etwa in der Form
+\begin{verbatim}
+\bibliography{acompat,jourfull,user1,user2,user3}\bibliographystyle{plain}
+\end{verbatim}
+nichts mehr im Wege. Nat"urlich funktioniert die automatische Sprachauswahl
+jetzt nicht mehr bei den F"ull"-w"or"-tern, sondern nur noch bei den
+"`handgemachten"' \verb|ifger|-Konstruktionen.
+
+Abschlie"send noch eine Anmerkung zur Gro"s-/Kleinschreibung von
+Zeitschriftentiteln. Die Stile der {\em plain family\/} setzen solche stets
+in Kleinschreibung um; so wird z.\,B. aus
+\begin{verbatim}
+TITLE="A Horror Story about Integration Methods"
+\end{verbatim}
+die Titelangabe "`A horror story about integration methods"'. Es wurde
+verschiedentlich die Meinung vertreten, da"s ein deutscher Bibliographiestil
+diese Umsetzung abschalten sollte, da sie f"ur deutsche Titel nicht ad"aquat
+ist. Der Autor der {\em adaptable family\/} schlie"st sich dieser Meinung
+nicht an (und hat die Umsetzung daher beibehalten): Gro"s-/Kleinschreibung
+von Zeitschriftentiteln ist nicht eine Frage der Sprache, in der das
+Dokument gesetzt ist, sondern eine Funktion der Sprache des Titels selbst.
+So sollte die Eingabe
+\begin{verbatim}
+TITLE="Graphische Sprachelemente in ALGOL 68"
+\end{verbatim}
+{\em immer\/} zu der Ausgabe "`Graphische Sprachelemente in ALGOL~68"'
+f"uhren -- auch in einem englischen Dokument; ebensowenig ist etwas dagegen
+einzuwenden, wenn im obigen Beispiel mit dem englischen Titel die Umsetzung
+auch in einem deutschen Dokument stattfindet.
+
+Es ist also {\em bei den einzelnen Titelangaben\/} daf"ur zu sorgen, da"s die
+Umsetzung ggf.~verhindert wird. Dies ist aber -- bei den Standard- wie bei
+den anpa"sbaren Stilen -- leicht m"oglich, wie im
+\BibTeX-Manual~\cite{bibtex-doc} beschrieben wird: Man schlie"se den
+gesamten Titel in ein zus"atzliches Paar geschweifter Klammern ein. Also
+bewirkt
+\begin{verbatim}
+TITLE="{Graphische Sprachelemente in ALGOL 68}"
+\end{verbatim}
+genau das Gew"unschte (die G"ansef"u"schen z"ahlen als "au"seres Klammerpaar
+und k"onnten auch durch geschweifte Klammern ersetzt werden, die
+zus"atzlichen Klammern sind aber trotzdem erforderlich). Statt dessen
+k"onnte man auch nur die gro"szuschreibenden W"orter oder Buchstaben
+klammern, z.\,B.
+\begin{verbatim}
+TITLE="{G}raphische {S}prachelemente in {ALGOL} 68"
+\end{verbatim}
+Diese Technik wendet man manchmal auch in englischen Titeln an, etwa in
+\begin{verbatim}
+TITLE="Stiff {ODE} Solvers: A Review of Current and Coming Attractions"
+\end{verbatim}
+so da"s sich der Titel "`Stiff ODE solvers: A review of current and coming
+attractions"' ergibt (das Wort nach dem Doppelpunkt bleibt ohne besondere
+Ma"snahme gro"sgeschrieben).

+\chap Introduction. %---------------------------------------------------------
+This file provides preamble definitions for use with the \BibTeX\
+`adaptable' family. It has to be read in at the beginning of a bibliography
+that was generated by one of the adaptable styles. Usually this will be done
+implicitly by means of an |@PREAMBLE| command in one of the bibliography
+databases included in the |\bibliography| enumeration (e.g.,
+\.{jourfull.bib} or \.{jourabbr.bib}), otherwise it must be |\input|
+explicitly right before the |\bibliography| macro is executed.
+
+\beginprog
+% This is APREAMBL.TEX, version 1.10e, written by Hans-Hermann Bode
+% (HHBODE@DOSUNI1.BITNET), for the BibTeX `adaptable' family, version 1.10.
+% See the file APREAMBL.DOC for a detailed documentation.
+
+% This program is distributed WITHOUT ANY WARRANTY, express or implied.

+\endprog
+
+\sect We use the---hopefully unique---identifier
+|\csname__APREAMBLE_TEX\endcsname| to decide whether this file was already
+read. If that identifier hasn't the meaning of |\relax|, we assume that this
+event arose and execute an |\endinput|; otherwise, we continue and store the
+|\catcode| of~|@| into it, which then will be set to~11 for use in local
+macro names. Hence, |\csname__APREAMBLE_TEX\endcsname| now is defined to
+prevent the file from multiply being input, and---on the other hand---we can
+restore the |\catcode| of~|@| in the end.
+
+\beginprog
+\expandafter\ifx\csname__APREAMBLE_TEX\endcsname\relax \else\endinput\fi
+\expandafter\chardef\csname__APREAMBLE_TEX\endcsname=\the\catcode`\@
+\catcode`\@=11
+\endprog
+
+\chap Setting style parameters. %---------------------------------------------
+The typesetting style of certain fields of the bibliography entries is
+determined by the |\abtype| command. It is called by the adaptable styles
+with two arguments: The first is a number that denotes the field in
+question, the second is the text to format. The meaning of the first
+parameter is declared in Tab.~1.
+$$\hbox{\sl Table~1: The first parameter of |\abtype|.\strut}$$
+$$\vbox{\halign{\strut\hfill#\hfill\quad & \vtop{\hsize=5cm\noindent#} \cr
+  \noalign{\hrule\hrule}
+  Value & Meaning \cr
+  \noalign{\hrule}
+  0 & author and editor names \cr
+  1 & titles of books and series \cr
+  2 & journal titles \cr
+  3 & journal volumes \cr
+  4 & journal numbers \cr
+  5 & dates \cr
+  \noalign{\hrule\hrule}
+  }}
+$$
+A comparison with the definition below shows that {\sc author and editor
+names} will be typeset in small caps, ``titles of books and series'' will be
+put in quotes, {\it journal titles\/} will come out in italics, {\bf journal
+volumes} will be boldface, and (journal numbers) and (dates) will be
+parenthesized. This may be changed to fit your needs.
+
+Currently, there is an English and a German version of the command. In the
+German version, the commands |\glqq| and |\grqq|---defined in
+\.{german.sty}---are used instead of |"`| and |"'|, in case we have
+|\mdqoff| (double-quotes inactive) but |\language=\german|.
+

+\endprog
+
+\chap Definition of phrases. %------------------------------------------------
+Phrases are defined by the |\abphrase| command. The only parameter is a code
+for the phrase that is explained in Tab.~2.
+$$\hbox{\sl Table~2: The parameter of |\abphrase|.\strut}$$
+$$\vbox{\halign{\strut\hfill#\hfill\quad & \vtop{\hsize=10cm\noindent#} \cr
+  \noalign{\hrule\hrule}

+  \noalign{\hrule}
+   0 & conjunction between two or before the last name of a name list \cr
+   1 & comes before the last conjunction of a name list \cr
+   2 & replaces names of co-authors and co-editors (``et al.'') \cr
+   3 & marks multiple editors \cr
+   4 & marks a single editor \cr
+   5 & ``of'' for a volume of a series or crossref \cr
+   6 & ``in'' for a number in a series \cr
+   7 & ``In'' for crossrefs to books, articles, etc. \cr
+   8 & comes before a volume number, lower-case \cr
+   9 & comes before a volume number, upper-case \cr
+  10 & comes before a series number, lower-case \cr
+  11 & comes before a series number, upper-case \cr
+  12 & comes after an edition number \cr
+  13 & comes before multiple page numbers \cr
+  14 & comes before a single page number \cr
+  15 & comes before a chapter number \cr
+  16 & denotes a technical report \cr
+  17 & denotes a master's thesis \cr
+  18 & denotes a phd thesis \cr
+  \noalign{\hrule\hrule}
+  }}
+$$
+Besides, macros for month names, edition numbers, and ``chapter'' names are
+defined. (The |\abedition| command may be extended for higher edition numbers
+and called directly or---better---via |@STRING| declarations in the \.{bib}
+files).
+
+For all these commands there exists a ``full'' and an ``abbreviated''
+version. The |\ifabfull| switch is automatically defined by the adaptable
+styles in front of the preamble and tells which version to use.
+
+Furthermore, phrases can be supplied for various languages. For now, English
+and German versions are available, but other languages might be implemented
+similarly. If you carry out such an implementation, {\sl watch out for
+spaces\/} that may be significant.
+

+
+\chap Establishing a language switch. %---------------------------------------
+Now we have reached the point where we have to decide which of the language
+versions defined above to use. We like to make this decision automatically,
+without bothering the user with the declaration of an extra language
+command. This, however, is a somewhat delicate task since, although \TeX~3
+defines a |\language| counter, it doesn't say which code belongs to a given
+actual language (and, in addition, what about former \TeX\ versions?).
+
+It will come out that at least two groups of users should agree with our way
+to handle this: those who always write English documents and those who use
+the \.{german.sty} macro package. If we detect that \.{german.sty} is loaded
+we follow the codes defined there, otherwise we create an English
+bibliography. (Due to this, \.{german.sty} clearly has to be loaded before
+\.{apreambl.tex}---if at all---; this should be no problem with \LaTeX\
+where |german| is a document-style option, but with plain \TeX, take care
+that |\input german.sty| comes before |\bibliography{...}| if necessary.)
+
+Incidentally, the checking of certain conditions and the definitions made in
+the following are stolen from \.{german.sty}.
+
+First, if |\language| has not yet been declared we allocate a counter:
+
+\beginprog
+\expandafter\ifx\csname language\endcsname\relax % \ifundefined{language}
+  \csname newcount\endcsname\language
+\fi
+\endprog
+
+\sect If the macro |\mdqon| is undefined or is equal to |\relax|, it is
+assumed that \.{german.sty} is not included. In this case we define language
+codes according to \.{german.sty} and select |\USenglish| as the default
+setting. The |\chardef| declarations for the other languages aren't really
+necessary for \.{apreambl}, but in this manner the user can rely on the
+fact that |\USenglish|, |\german|, |\austrian|, |\french|, and |\english| are
+defined and have appropriate meanings whether \.{german.sty} is loaded or
+not; so, he or she can make use of them in his or her \.{bib} files for
+special purposes.
+
+A slight surprise came about when \.{german.sty}, version 2.4a, was
+released: the control sequences above disappeared and are replaced by
+|\l@USenglish| etc. Furthermore, one can't rely on certain values for these
+anymore. To fix this problem quickly, we check for that new control
+sequences, if \.{german.sty} is loaded, and in case define the old ones
+appropriately (this may be changed in the future). Thus, \.{apreambl} should
+work with old and new versions of \.{german.sty}.
+
+\beginprog
+\expandafter\ifx\csname mdqon\endcsname\relax % \ifundefined{mdqon}
+  \chardef\USenglish=0
+  \chardef\german=1
+  \chardef\austrian=1
+  \chardef\french=2
+  \chardef\english=0
+  \language\USenglish
+\else
+  \expandafter\ifx\csname l@USenglish\endcsname\relax \else
+    \chardef\USenglish=\l@USenglish\fi
+  \expandafter\ifx\csname l@german\endcsname\relax \else
+    \chardef\german=\l@german\fi
+  \expandafter\ifx\csname l@austrian\endcsname\relax \else
+    \chardef\austrian=\l@austrian\fi
+  \expandafter\ifx\csname l@french\endcsname\relax \else
+    \chardef\french=\l@french\fi
+  \expandafter\ifx\csname l@english\endcsname\relax \else
+    \chardef\english=\l@english\fi
+\fi
+\endprog
+
+\sect Finally, depending on the language switch and the abbreviation mode, one
+of the macro sets is chosen. (At the moment, since only English and German
+macro versions are available, the German versions are used for |\german| and
+|\austrian|, and the English versions are used for all other languages.)
+
+\beginprog
+\ifnum\language=\german
+  \abtype@german \abetc@german
+\else\ifnum\language=\austrian
+  \abtype@german \abetc@german
+\else
+  \abtype@english \abetc@english

+	% Copyright (C) 1985, all rights reserved.

+	% (2) if you do make changes, you name it something other than

+% Please notify Oren Patashnik (PATASHNIK@SCORE.STANFORD.EDU) of any bugs in

+%
+% This is file btxbxt.doc; it helps document bibliography styles,
+% and is also a template file that you can use to make
+% several different style files, if you have access to a C preprocessor.
+% For example, the standard styles were made by doing something like
+%	cpp -P -DAPLAIN btxabst.doc aplain.txt
+%	cpp -P -DAUNSRT btxabst.doc aunsrt.txt
+%	cpp -P -DAALPHA btxabst.doc aalpha.txt
+%	cpp -P -DAABBRV btxabst.doc aabbrv.txt
+%	cpp -P -DANOTIT btxabst.doc anotit.txt
+%	cpp -P -DAUNSNOT btxabst.doc aunsnot.txt
+% and then renaming after removing unwanted comments and blank lines.
+% If you don't have access,
+% you can edit this file by hand to imitate the preprocessor,
+% with the following explanation of the C preprocessor constructs used here.
+%
+% The output of the preprocessor is the same as the input, except that certain
+% lines will be excluded (and some blank lines will be added).  The sequence
+%	#if VAR
+%	    lines to be included when VAR is not zero
+%	#else
+%	    lines to be included when VAR is zero
+%	#endif
+% (with the #-signs appearing in column 1) means that one set or the other of
+% the lines are to be included depending on the value of VAR.
+% The #else part is optional.  Comments can be added after #else and #endif.
+% Variables can be set by
+%	#define VAR value
+% and one can also use #ifdef VAR to see if VAR has any value, and #ifndef
+% to see if it has none.
+% Another #if form used in this file is #if !VAR, which includes the lines
+% after the #if only if VAR is zero.
+%
+% Convention: Use all uppercase identifiers for these preprocessor variables
+% so you can spot them easily
+%
+% The command line to the preprocessor should define one of APLAIN, AUNSRT, AALPHA
+% or AABBRV (though APLAIN will be used by default if none is given),
+% and the following lines will set various boolean variables to control the
+% various lines that are chosen from the rest of the file.
+% Each boolean variable should be set true (1) or false (0) in each style.
+% Here are the current variables, and their meanings:
+%	LAB_ALPH:	an alphabetic label is used (if false then a numeric
+%			    label is used)
+%	SORTED:		the entries should be sorted by label (if nonnumeric)
+%			    and other info, like authors (if false, then
+%			    entries remain in order of occurrence)
+%	NAME_FULL:	the authors, editors, etc., get the full names as
+%			    given in the bibliography file (if false, the first
+%			    names become initials)
+%	ATIT_LOWER:	titles of non-"books" (e.g., articles) should be
+%			    converted to lower-case, except the first letter or
+%			    first letter after a colon
+%			    (if false then they appear as in the database)
+%	MONTH_FULL:	months are spelled out in full (if false, then
+%			    they're abbreviated); now used generally for 
+%			    distinction between ``full'' and ``abbreviated'' 
+%			    styles (H2B)
+%	JOUR_FULL:	macro journal names are spelled out in full
+%			    (if false then they are abbreviated, currently
+%			    as they appear in ACM publications); no more used 
+%			    (H2B)
+%	NO_TITLE:	the titles of articles, incollections, inproceedings 
+%			and techreports are omitted, if there are other 
+%			informations to identify the work cited (added by H2B)

+%   Entry formatting: Similar to that recommended by Mary-Claire van Leunen
+%	in "A Handbook for Scholars".  Book-like titles are italicized
+%	(emphasized) and non-book titles are converted to sentence
+%	capitilization (and not enclosed in quotes).
+%	This file outputs a \newblock between major blocks of an entry
+%	(the name \newblock is analogous to the names \newline and \newpage)
+%	so that the user can obtain an "open" format, which has a line break
+%	before each block and lines after the first are indented within blocks,
+%	by giving the optional \documentstyle argument `openbib';
+%	The default is the "closed" format---blocks runs together.
+%
+%   Citation alphabetic label format:
+%		[Knu73] for single author (or editor or key)
+%		[AHU83] (first letters of last names) for multiple authors
+%
+%   Citation label numberic format:
+%		[number]
+%
+%   Reference list ordering for sorted, alphabetic lables:
+%		alphabetical by citation label, then by author(s) or whatever
+%		passes for author in the absence of one, then by year,
+%		then title
+%
+%   Reference list ordering for sorted, numeric lables:

+%    3/28/85	(OP)	First release, version 0.98b for BibTeX 0.98f.
+%    5/ 9/85	(OP)	Version 0.98c for BibTeX 0.98i:
+%			fixed Theoretical Computer Science macro name;
+%			fixed the format.vol.num.pages function.
+%    1/24/88	(OP)	Version 0.99a for BibTeX 0.99a, main changes:
+%			assignment operator (:=) arguments reversed;
+%			the preamble$ function outputs the database PREAMBLE;
+%			entry.max$ and global.max$ (built-in) variables replace
+%			entry.string.max and global.string.max functions;
+%			alphabetizing by year then title, not just title;
+%			many unnecessary ties removed; \it ==> \em;
+%			the `alpha' style uses a superscripted `+' instead of a
+%			`*' for unnamed names in constructing the label;
+%			the `abbrv' style now uses "Mar." and "Sept.";
+%			the functions calc.label and presort now look at just
+%			the fields they're supposed to;
+%			BOOKLET, MASTERSTHESIS, TECHREPORT use nonbook titles;
+%			INBOOK and INCOLLECTION take an optional type (e.g.
+%			type = "Section"), overriding the default "chapter";
+%			BOOK, INBOOK, INCOLLECTION, and PROCEEDINGS now allow
+%			either volume or number, not just volume;
+%			INCOLLECTION now allows an edition and series field;
+%			PROCEEDINGS and INPROCEEDINGS now use the address field
+%			to tell where a conference was held;
+%			INPROCEEDINGS and PROCEEDINGS now allow either volume
+%			or number, and also a series field;
+%			MASTERSTHESIS and PHDTHESIS accept types other than
+%			"Master's thesis" and "PhD thesis";
+%			UNPUBLISHED now outputs, in one block, note then date;
+%			MANUAL now prints out the organization in
+%			the first block if the author field is empty;
+%			MISC can't be empty---it requires some optional field.
+%    3/23/88    (OP)    Version 0.99b for BibTeX 0.99c---changed the three
+%                       erroneous occurrences of `cite ' to `cite$ '; this
+%                       change didn't affect the four standard styles, so the
+%                       0.99a versions of those styles are still current.
+%    5/11/91    (H2B)	Version 1.00 of the `b' style family by 
+%			Hans-Hermann Bode with the following changes and 
+%			extensions: renaming the styles, adding a `anotit' 
+%			style; adding an output.state named continue.sentence 
+%			and a new.clause function; setting author names in 
+%			small caps, putting booktitles in quotes rather than 
+%			to emphasize them, boldfacing volume numbers of 
+%			journals, including date specification in parentheses, 
+%			discarding macros for journal names.
+%    6/15/91    (H2B)	Version 1.10 of the `adaptable' style family (which 
+%			replaces the `b' style family) with adaptable 
+%			type styles, phrases, conjunctions etc., new macros 
+%			for edition numbers and ``chapter'' names and a new 
+%			`aunsnot' style.
+%
+% The ENTRY declaration
+%   Like Scribe's (according to pages 231-2 of the April '84 edition),
+%   but no fullauthor or editors fields because BibTeX does name handling.
+%   The annote field is commented out here because this family doesn't
+%   include an annotated bibliography style.  And in addition to the fields
+%   listed here, BibTeX has a built-in crossref field, explained later.
+
+ENTRY
+% Fields:
+  { address
+%	    Usually the address of a publisher or other type of organization.
+%	    Put information in this field only if it helps the reader find the
+%	    thing---for example you should omit the address of a major
+%	    publisher entirely.  For a PROCEEDINGS or an INPROCEEDINGS,
+%	    however, it's the address of the conference; for those two entry
+%	    types, include the publisher's or organization's address, if
+%	    necessary, in the publisher or organization field.
+%    annote
+%	    Long annotation---for annotated bibliographies (begins sentence).
+    author
+%	    Name(s) of author(s), in BibTeX name format.
+    booktitle
+%	    Book title when the thing being referenced isn't the whole book.
+%	    For book entries, the title field should be used instead.
+    chapter
+%	    Chapter (or section or whatever) number.
+    edition
+%	    Edition of a book---should be an ordinal (e.g., "Second").
+    editor
+%	    Name(s) of editor(s), in BibTeX name format.
+%	    If there is also an author field, then the editor field should be
+%	    for the book or collection that the work appears in.
+    howpublished
+%	     How something strange has been published (begins sentence).
+    institution
+%	    Sponsoring institution of a technical report.
+    journal
+%	    Journal name (macros are provided for many).
+    key
+%	    Alphabetizing, labeling, and cross-referencing key
+%	    (needed when an entry has no author or editor).
+    month
+%	    Month (macros are provided).
+    note
+%	    To help the reader find a reference (begins sentence).
+    number
+%	    Number of a journal or technical report, or of a work in a series.
+    organization
+%	    Organization sponsoring a conference (or publishing a manual); if
+%	    the editor (or author) is empty, and if the organization produces
+%	    an awkward label or cross reference, you should put appropriately
+%	    condensed organization information in the key field as well.
+    pages
+%	    Page number or numbers (use `--' to separate a range, use `+'
+%	    to indicate pages following that don't form a simple range).
+    publisher
+%	    Publisher name.
+    school
+%	    School name (for theses).
+    series
+%	    The name of a series or set of books.
+%	    An individual book will will also have it's own title.
+    title
+%	    The title of the thing you're referred to.
+    type
+%	    Type of a Techreport (e.g., "Research Note") to be used instead of
+%	    the default "Technical Report"; or, similarly, the type of a
+%	    thesis; or of a part of a book.
+    volume
+%	    The volume number of a journal or multivolume work.
+    year
+%	    The year should contain only numerals (technically, it should end
+%	    with four numerals, after purification; doesn't a begin sentence).
+  }
+% There are no integer entry variables
+  {}
+% These string entry variables are used to form the citation label.
+% In a storage pinch, sort.label can be easily computed on the fly.
+#if LAB_ALPH
+#if SORTED
+  { label extra.label sort.label }
+#else !SORTED
+% It doesn't seem like a good idea to use an order-of-citation
+% reference list when using alphabetic labels, but when this happens
+% we do things a little differently
+  { label }
+#endif SORTED
+#else !LAB_ALPH
+  { label }
+#endif LAB_ALPH
+
+% The following macros have to be defined by the user (e.g., with the 
+% expansions given below) for formatting of certain fields and to replace the 
+% constant built-in strings for phrases, conjunctions etc. This makes the 
+% BibTeX style files adaptable---a feature introduced by H2B.
+%
+% The type style of certain fields is determined by the \abtype command. The 
+% first parameter is a number, that denotes the field in question, namely:
+%   0	author and editor names,
+%   1	titles of books and series,
+%   2	journal titles,
+%   3	journal volumes,
+%   4	journal numbers, and
+%   5	dates.
+% The second parameter is the text to format. Hence, the type style macro 
+% could be something like:
+%   \def\abtype#1#2{%
+%     \ifcase#1{\sc#2}\or``#2''\or{\em#2\/}\or{\bf#2}\or(#2)\or(#2)\else#2\fi}
+% The \else clause returns the text unformatted, if the command is called with 
+% an undefined field number (which is not used in this file).
+%
+% Phrases are defined by the \abphrase command. The only parameter is a code 
+% for the phrase:
+%    0	conjunction between two or before the last name of a name list
+%    1	comes before the last conjunction of a name list
+%    2	replaces names of co-authors and co-editors (``et al.'')
+%    3	marks multiple editors
+%    4	marks a single editor
+%    5	``of'' for a volume of a series or crossref
+%    6	``in'' for a number in a series
+%    7	``In'' for crossrefs to books, articles, etc.
+%    8	comes before a volume number, lower-case
+%    9	comes before a volume number, upper-case
+%   10	comes before a series number, lower-case
+%   11	comes before a series number, upper-case
+%   12	comes after an edition number
+%   13	comes before multiple page numbers
+%   14	comes before a single page number
+%   15	comes before a chapter number
+%   16	denotes a technical report
+%   17	denotes a master's thesis
+%   18	denotes a phd thesis
+% An appropriate definition of the phrases macro would be:
+%   \def\abphrase#1{%
+%     \ifcase#1{ and }\or{,}\or{ et~al.}\or{, editors}\or{, editor}\or%
+%       { of }\or{ in }\or{In }\or{volume}\or{Volume}\or{number}\or{Number}\or%
+%       { edition}\or{pages}\or{page}\or{chapter}\or%
+%       {Technical Report}\or{Master's thesis}\or{PhD thesis}\fi}
+
+% Each entry function starts by calling output.bibitem, to write the
+% \bibitem and its arguments to the .BBL file.  Then the various fields
+% are formatted and printed by output or output.check.  Those functions
+% handle the writing of separators (commas, periods, \newblock's),
+% taking care not to do so when they are passed a null string.
+% Finally, fin.entry is called to add the final period and finish the
+% entry.
+%
+% A bibliographic reference is formatted into a number of `blocks':
+% in the open format, a block begins on a new line and subsequent
+% lines of the block are indented.  A block may contain more than
+% one sentence (well, not a grammatical sentence, but something to
+% be ended with a sentence ending period).  The entry functions should
+% call new.block whenever a block other than the first is about to be
+% started.  They should call new.sentence whenever a new sentence is
+% to be started.  The output functions will ensure that if two
+% new.sentence's occur without any non-null string being output between
+% them then there won't be two periods output.  Similarly for two
+% successive new.block's.
+%
+% The output routines don't write their argument immediately.
+% Instead, by convention, that argument is saved on the stack to be
+% output next time (when we'll know what separator needs to come
+% after it).  Meanwhile, the output routine has to pop the pending
+% output off the stack, append any needed separator, and write it.
+%
+% To tell which separator is needed, we maintain an output.state.
+% It will be one of these values:
+%	before.all		just after the \bibitem
+%	continue.sentence	in the middle of a sentence: blank---no 
+%					comma---needed if more sentence is 
+%					output (value added by H2B)
+%	mid.sentence		in the middle of a sentence: comma needed
+%					if more sentence is output
+%	after.sentence		just after a sentence: period needed
+%	after.block		just after a block (and sentence):
+%					period and \newblock needed.
+% Note: These styles don't use after.sentence.
+% This note doesn't apply really (H2B).
+%
+% VAR: output.state : INTEGER		-- state variable for output
+%
+% The output.nonnull function saves its argument (assumed to be nonnull)
+% on the stack, and writes the old saved value followed by any needed
+% separator.  The ordering of the tests is decreasing frequency of
+% occurrence.
+%
+% output.nonnull(s) ==
+%  BEGIN
+%	s := argument on stack
+%	if output.state = continue.sentence then	-- added by H2B
+%		write$(pop() * " ")			-- dto.
+%			-- "pop" isn't a function: just use stack top
+%	else
+%		if output.state = mid.sentence then
+%		    write$(pop() * ", ")
+%		else
+%		    if output.state = after.block then
+%			write$(add.period$(pop()))
+%			newline$
+%			write$("\newblock ")
+%		    else
+%			if output.state = before.all then
+%			    write$(pop())
+%			else	    -- output.state should be after.sentence
+%			    write$(add.period$(pop()) * " ")
+%			fi
+%		    fi
+%		fi
+%		output.state := continue.sentence
+%	fi
+%	push s on stack
+%  END
+%
+% The output function calls output.nonnull if its argument is non-empty;
+% its argument may be a missing field (thus, not necessarily a string)
+%
+% output(s) ==
+%  BEGIN
+%	if not empty$(s) then output.nonnull(s)
+%	fi
+%  END
+%
+% The output.check function is the same as the output function except that, if
+% necessary, output.check warns the user that the t field shouldn't be empty
+% (this is because it probably won't be a good reference without the field;
+% the entry functions try to make the formatting look reasonable even when
+% such fields are empty).
+%
+% output.check(s,t) ==
+%  BEGIN
+%	if empty$(s) then
+%	    warning$("empty " * t * " in " * cite$)
+%	else output.nonnull(s)
+%	fi
+%  END
+%
+% The output.bibitem function writes the \bibitem for the current entry
+% (the label should already have been set up), and sets up the separator
+% state for the output functions.  And, it leaves a string on the stack
+% as per the output convention.
+%
+% output.bibitem ==
+%  BEGIN
+%	newline$
+%	write$("\bibitem[")	% for alphabetic labels,
+%	write$(label)		% these three lines
+%	write$("]{")		% are used
+%	write$("\bibitem{")		% this line for numeric labels
+%	write$(cite$)
+%	write$("}")
+%	push "" on stack
+%	output.state := before.all
+%  END
+%
+% The fin.entry function finishes off an entry by adding a period to the
+% string remaining on the stack.  If the state is still before.all
+% then nothing was produced for this entry, so the result will look bad,
+% but the user deserves it. (We don't omit the whole entry because the
+% entry was cited, and a bibitem is needed to define the citation label.)
+%
+% fin.entry ==
+%  BEGIN
+%	write$(add.period$(pop()))
+%	newline$
+%  END
+%
+% The new.block function prepares for a new block to be output, and
+% new.sentence prepares for a new sentence.
+% Added by H2B was new.clause, that prepares for a new subordinate clause.
+%
+% new.block ==
+%  BEGIN
+%	if output.state <> before.all then

+% Here are some functions for formatting chunks of an entry.
+% By convention they either produce a string that can be followed by
+% a comma or period (using add.period$, so it is OK to end in a period),
+% or they produce the null string.
+%
+% A useful utility is the field.or.null function, which checks if the
+% argument is the result of pushing a `missing' field (one for which no
+% assignment was made when the current entry was read in from the database)
+% or the result of pushing a string having no non-white-space characters.
+% It returns the null string if so, otherwise it returns the field string.
+% Its main (but not only) purpose is to guarantee that what's left on the
+% stack is a string rather than a missing field.
+%
+% field.or.null(s) ==
+%  BEGIN
+%	if empty$(s) then return ""
+%	else return s
+%  END
+%
+% Another helper function is emphasize, which returns the argument emphazised,
+% if that is non-empty, otherwise it returns the null string.  Italic
+% corrections aren't used, so this function should be used when punctation
+% will follow the result. In contrast to the last sentence, now italic 
+% corrections are always used (H2B).
+%
+% emphasize(s) ==
+%  BEGIN
+%	if empty$(s) then return ""
+%	else return "{\em " * s * "\/}"
+%  END
+%
+% Similar to emphasize is capitalize, from which the argument comes out in 
+% small caps. This function was added by H2B.
+%
+% capitalize(s) ==
+%  BEGIN
+%	if empty$(s) then return ""
+%	else return "{\sc " * s * "}"
+%  END
+%
+% And here is another such function---added by H2B---, that returns a boldface 
+% string.
+%
+% boldface(s) ==
+%  BEGIN
+%	if empty$(s) then return ""
+%	else return "{\bf " * s * "}"
+%  END
+%
+% The function quote will put its argument string in quotes (added by H2B).
+%
+% quote(s) ==
+%  BEGIN
+%	if empty$(s) then return ""
+%	else return "``" * s * "''"
+%  END
+%
+% And parentheses includes it in parentheses (added by H2B).
+%
+% parentheses(s) ==
+%  BEGIN
+%	if empty$(s) then return ""
+%	else return "(" * s * ")"
+%  END
+%
+% The format.names function formats the argument (which should be in
+% BibTeX name format) into "First Von Last, Junior", separated by commas
+% and with an "and" before the last (but ending with "et~al." if the last
+% of multiple authors is "others").  This function's argument should always
+% contain at least one name.
+%
+% VAR: nameptr, namesleft, numnames: INTEGER
+% pseudoVAR: nameresult: STRING		(it's what's accumulated on the stack)
+%
+% format.names(s) ==
+%  BEGIN
+%	nameptr := 1
+%	numnames := num.names$(s)
+%	namesleft := numnames
+%	while namesleft > 0

+%		else if numnames > 2
+%		       then nameresult := nameresult * ","
+%		     fi
+%		     if t = "others"
+%		       then nameresult := nameresult * " et~al."

+%	    else nameresult := t
+%	    fi
+%	    nameptr := nameptr + 1
+%	    namesleft := namesleft - 1
+%	  od
+%	return nameresult
+%  END
+%
+% The format.authors function returns the result of format.names(author)
+% if the author is present, or else it returns the null string.
+% Capitalization of names added by H2B.
+%
+% format.authors ==
+%  BEGIN
+%	if empty$(author) then return ""
+%	else return capitalize(format.names(author))
+%	fi
+%  END
+%
+% Format.editors is like format.authors, but it uses the editor field,
+% and appends ", editor" or ", editors".
+% Capitalization of names added by H2B.
+%
+% format.editors ==
+%  BEGIN
+%	if empty$(editor) then return ""
+%	else
+%	    if num.names$(editor) > 1 then

+%
+% The macros for the month names now expand to TeX macros, so they are 
+% adaptable too. Thus no conditional MONTH_FULL is needed anymore (H2B).
+%
+% The \abmonth macro should be defined by the user as something like:
+%   \def\abmonth#1{\ifcase#1\or January\or February\or March\or April\or May\or 
+%     June\or July\or August\or September\or October\or November\or December\fi}

+MACRO {jul} {"\abmonth{7}"}

+MACRO {sep} {"\abmonth{9}"}
+
+MACRO {oct} {"\abmonth{10}"}
+
+MACRO {nov} {"\abmonth{11}"}
+
+MACRO {dec} {"\abmonth{12}"}
+
+% The next ten macros are provided for edition numbers. For higher numbers the 
+% \abedition command should be extended by the user and called directly or---
+% better---via @STRING declarations in the BIB files. The \abedition command 
+% to be defined by the user is, e.g.:
+%   \def\abedition#1{\ifcase#1\or First\or Second\or Third\or Fourth\or Fifth\or 
+%     Sixth\or Seventh\or Eighth\or Ninth\or Tenth\else?\fi}
+
+MACRO {first}   {"\abedition{1}"}
+
+MACRO {second}  {"\abedition{2}"}
+
+MACRO {third}   {"\abedition{3}"}
+
+MACRO {fourth}  {"\abedition{4}"}
+
+MACRO {fifth}   {"\abedition{5}"}
+
+MACRO {sixth}   {"\abedition{6}"}
+
+MACRO {seventh} {"\abedition{7}"}
+
+MACRO {eighth}  {"\abedition{8}"}
+
+MACRO {ninth}   {"\abedition{9}"}
+
+MACRO {tenth}   {"\abedition{10}"}
+
+% Finally, some macros are defined to re-dedicate the CHAPTER field via the 
+% TYPE field. An appropriate \abchapter command were:
+%    \def\abchapter#1{\ifcase#1Section\or Paragraph\or Appendix\or Part\fi}
+
+MACRO {section}   {"\abchapter{0}"}
+
+MACRO {paragraph} {"\abchapter{1}"}
+
+MACRO {appendix}  {"\abchapter{2}"}
+
+MACRO {part}      {"\abchapter{3}"}
+
+% Journals are either written out in full or abbreviated;
+% the abbreviations are like those found in ACM publications.
+%
+% To get a completely different set of abbreviations, it may be best to make
+% a separate .bib file with nothing but those abbreviations; users could then
+% include that file name as the first argument to the \bibliography command.
+%
+% All journal macros were commented off, because the set applies only to a 
+% very special field of sciences; so the hint in the previous paragraph 
+% becomes mandatory (H2B).

+%
+% Exactly what fields we look at in constructing the primary part of the label
+% depends on the entry type; this selectivity (as opposed to, say, always
+% looking at author, then editor, then key) helps ensure that "ignored" fields,
+% as described in the LaTeX book, really are ignored.  Note that MISC is part
+% of the deepest `else' clause in the nested part of calc.label; thus, any
+% unrecognized entry type in the database is handled correctly.
+%
+% There is one auxiliary function for each of the four different sequences of
+% fields we use.  The first of these functions looks at the author field, and
+% then, if necessary, the key field.  The other three functions, which might
+% look at two fields and the key field, are similar, except that the key field
+% takes precedence over the organization field (for labels---not for sorting).
+%
+% The calc.label function calculates the preliminary label of an entry, which
+% is formed by taking three letters of information from the author or editor or
+% key or organization field (depending on the entry type and on what's empty,
+% but ignoring a leading "The " in the organization), and appending the last
+% two characters (digits) of the year. It is an error if the appropriate fields
+% among author, editor, organization, and key are missing, and we use
+% the first three letters of the cite$ in desperation when this happens.
+% The resulting label has the year part, but not the name part, purify$ed
+% (purify$ing the year allows some sorting shenanigans by the user).
+%
+% This function also calculates the version of the label to be used in sorting.
+%
+% The final label may need a trailing 'a', 'b', etc., to distinguish it from
+% otherwise identical labels, but we can't calculated those "extra.label"s
+% until after sorting.

+%
+% The fields used here are: the sort.label for alphabetic labels (as set by

+% (chopping off a leading "The ", "A ", or "An ").

+% The names within a part will be separated by a single blank
+% (such as "brinch hansen"), two will separate the name parts themselves
+% (except the von and last), three will separate the names,

+\chap Introduction.
+
+\WEB{} systems allow the documentation of programs by supporting the
+separation in program fragments which can be collected and rearranged
+afterwards.  This allows {\it top-down\/} programming as well as the
+{\it bottom-up\/} design of programs.  Each program fragment can be
+documented, usually with \TeX{}.  A disadvantadge is that \WEB{}
+actually exists only for a few programming languages (Pascal, C,
+Modula-2).  Besides, building up \WEB{} systems for ``exotic''
+programming languages like \TeX{} is very difficult.
+
+This macro package was built to allow good documentation for programs
+in languages for which \WEB{} doesn't exist.  It separates a program
+text in sections that can be documented.  All sections, collected
+sequentially, will result in the complete program.  In every section
+begin and end of the program part are marked with |\beginprog| and
+|\endprog|, this program part will be formatted as it is input
+(``verbatim'').
+
+The separation of the sections is done in this version (which is based
+on Plain~\TeX{}) by the macros |\chap| and |\sect|.  But this can be
+changed easily, e.g.\ for preparing the documentation with \LaTeX{}.
+Then the last section group of this macro package must be omitted and
+the rest must be realized as a style option.
+
+In the documentation part of a section text pieces, e.g.\ names of
+variables, can be inserted verbatim to demonstrate the connection to
+the program text.  These parts are included in vertical bars
+(`{\tt\vbar}') while the vertical bar itself can be obtained by
+|\origvert|.
+
+This macro package does not offer the creation of an index because it is not
+known which syntactical tokens the language has that should be mentioned in
+an index.  If you want a table of contents, just say |\contentspage| at the
+end of your document (you need not put a |\bye| after that, |\contentspage|
+does this for you).  Some remarks about future enhancements which should be
+done urgently are set in slanted type.
+
+
+\sect We have to realize three parts:  (1)~the formatting of rather
+small verbatim texts in a line, (2)~the formatting of larger parts of
+program and (3)~the document structuring elements for the separation
+of the sections.  Before we start we declare some shorthands for
+category codes.
+
+By declaring the at sign~(`|@|') as well as the underscore~`(|_|)' as
+letters we can use them in our macros.
+{\tolerance=10000
+(I agree with D.~Knuth that |\identifier_several_words_long| is much
+better readable than |\IdentifierSeveralWordsLong| and both are better
+than |\pr@@@s|.)
+With the at sign we can use the ``private'' Plain macros and with the
+underscore we can make our own macros more readable.  But as we have
+to restore these category codes at the end of this macro file we store
+their former values in the control sequences |\atcode| and |\uscode|.
+This method is better than the usage of a group because not all macros
+have to be defined global this way.

+
+
+\chap Local Verbatim Formatting.
+
+The main point of every verbatim formatting is the switching of the
+character codes of all characters that have a special \TeX{} meaning.
+This can be done with the control sequence |\dospecials| that applies
+the control sequence |\do| to all special characters.  Additionally,
+every line is regarded as a paragraph without indentation.  Between
+two paragraphs, i.e.\ between two lines, no extra space is set.
+Finally all blanks and tabular characters shall be obeyed and the
+inter word space after sentence terminators shall not be enlarged.
+The activation of the tabular characters with |\obeytabs| is
+equivalent to |\obeyspaces| in {\tt plain.tex\/}.
+
+Verbatim texts are set in monospace, we use (like in \WEB{}) the
+character set with the extended {\mc ASCII}.  For \LaTeX{} we would
+have to add here |\ttex| to all size modifications like |\xpt|,
+|\xiipt|, etc.
+
+\beginprog
+\font\tentex=cmtex10            % typewriter extended ASCII 10pt
+\let\ttex=\tentex               % only for PLAIN with base size 10pt
+
+\def\setup_verbatim{%
+   \def\do##1{\catcode`##1\other}\dospecials
+   \parskip\z@skip \parindent\z@
+   \obeylines \obeyspaces \obeytabs \frenchspacing
+   \ttex
+   }
+
+\let\tab=\space
+\begingroup
+   \catcode`\^^I=\active%       % Attention: no tabs!
+   \gdef\obeytabs{\catcode`\^^I=\active\def^^I{\tab}}
+   \global\let^^I=\tab%         % if an active tab appears in a \write
+\endgroup
+\endprog
+
+\sect After having saved the old meaning of `{\tt\vbar}' in
+|\origvert| and after declaring |\vbar| as a synonym for the character
+that has the code of a vertical bar in the actual font, the vertical
+bar can be made active.  Then we call |\setup_verbatim|.  But the
+newline characters shall not be processed, they shall be regarded like
+blank space.  This can be reached by defining |\par| as |\space|.
+
+The next vertical bar in the input closes the group which becomes an
+(unbreakable) |\hbox| then.  The old meanings of the special
+characters and of the vertical bar are restored and \TeX{} is in
+normal (horizontal) mode again.
+
+\beginprog
+\let\origvert=|
+\chardef\vbar=`\|
+
+\catcode`\|=\active
+
+\def|{%
+   \leavevmode
+   \hbox\bgroup
+      \let\par\space \setup_verbatim
+      \let|\egroup
+   }
+\endprog
+
+
+
+
+\chap  Program Fragments in Verbatim.
+
+We need macros to format the program fragments without any
+linebreaking.  Such a text area shall start with the macro
+|\beginprog| and end with |\endprog|.  The macro |\endprog| must stand
+at the very beginning of a line and must be followed by white space
+(blank, tab or newline character).  After |\beginprog| as well as
+after |\endprog| the rest of the line is ignored.
+
+Two demands must be regarded:  There should be no length restrictions
+for the processed text, and the tabular characters should be expanded
+so that this macro works on PC's and on VAXes, too.
+
+
+\sect The implementation method is quite simple:  We read the next
+line, test, wether the end is reached (by comparing with |\endprog|)
+and otherwise set the character actually read.  Every character is
+inspected and tabular characters are expanded.
+
+Wether a line is set or wether the end of the processed area is
+reached is indicated by the switch |\if@print|.  At the beginning of
+the |\beginprog| macro most settings are done with |\setup_verbatim|
+(the vertical bar must be handled separately) and the rest of the line
+is ignored.  As everything is done within a group, the end of the
+verbatim text can be processed by simply closing this group.
+
+For the user it looks as if |\endprog| terminates the processing, but
+it just serves for the identification of the end, the true processing
+is done with the internal macro |\end_verbatim|.
+
+\beginprog
+\newif\if@print
+
+\def\beginprog{%
+   \endgraf
+   \bigbreak
+   \begingroup
+      \setup_verbatim \catcode`\|\other
+      \@printtrue
+      \ignore_rest_line
+   }
+\let\end_verbatim=\endgroup             % internal command !
+\endprog
+
+
+\sect The first line is ignored, all the other lines are identified
+with |\set_next_line| and processed with |\do_set|.  This separation
+in identification and processing allows that the line end character is
+active in the definition only for a short time.
+
+When a line is to be formatted, we first check with |\check_print|
+wether it contains |\endprog|, otherwise it is printed with
+|\print_char|.  The printing must be done for every character
+individually because we want to check for tabular characters; the
+exact algorithm is described below.  Here we just have to note that
+|\print_char| is used with two parameters of which the second one is
+finished with the token |\end_line|.  The first parameter is the first
+character of the line, the second parameter is the rest of the line.
+If the line is empty, the argument of |\do_set| is empty, too; so the
+activation of |\print_char| must be finished with two |\end_line|.
+Then the first |\end_line| is the first argument for |\print_char| and
+the second argument is empty.  But if the line did contain something,
+the second |\end_line| is evaluated, for this case it is defined as
+|\relax|.
+
+At last we call |\set_next_line| again to format the next line.  If
+the end is reached, i.e.\ if a line with |\endprog| was found,
+|\set_next_line| is redefined as |\relax|.  This can be done because
+the original meaning is restored while closing the group with
+|\end_verbatim|.
+
+\beginprog
+\begingroup
+   \obeylines%          % ^^M is active! ==> every line must end with %
+   \gdef\ignore_rest_line#1^^M{\set_next_line}%

+\let\end_line=\relax
+\endprog
+
+
+\sect Before we look at the problem of formatting a line, we declare
+|\check_print| that checks the end of the verbatim mode.  We have to
+do two things:  we must split everything in front of the first blank
+or tabular character and compare for identity with |\endprog|.  The
+splitting is easy because the line which is our first argument
+contains blanks and tabulators as active characters.  First we call
+|\cut_at_tab| that demands a tabular character as separator for its
+two pramenters so that everything in the line in front of the first
+tabulator is part of the first parameter.  If there is no tabular
+character in the line, we append one so that the second parameter is
+empty.  The same trick is used to separate the part in front of the
+first blank character from the resulting first part.
+
+The check is done with |\do_check|.  We use a separate macro here so
+that we can indent it (in the following definition blanks are active!)
+
+\beginprog
+\begingroup
+\obeyspaces\obeytabs
+\gdef\check_print#1{\cut_at_tab#1^^I\end_line}
+\gdef\cut_at_tab#1^^I#2\end_line{\check_first_part#1 \end_line}% blank !
+\gdef\check_first_part#1 #2\end_line{\do_check{#1}}
+\endgroup
+\endprog
+
+
+\sect |\do_check| compares the line with a sample line that is
+available in |\@endverbatim|.  During the definition of
+|\@endverbatim| it must be cared for that the escape character `|\|'
+is a printable character:  A comparison with |\ifx| demands identical
+category codes.  As a temporary escape character we use the vertical
+bar.
+
+\beginprog
+\def\do_check#1{%
+   \def\@line{#1}%
+   \ifx \@line\@endverbatim  \@printfalse
+   \fi
+   }
+
+{\catcode`\|=\escape  \catcode`\\=\other % | is temporary escape char

+}                                        % here \endgroup can't be used
+\endprog
+
+
+\sect Now we can set a line:  we start with the first character,
+followed by the rest of the line.  Each character is counted in
+|\char_count|.  At the beginning of a line |\char_count| is~1, this
+is reset at the end of the line.
+
+\goodbreak

+   \print_rest_of_line{#2}%
+   }
+\endprog
+
+
+\sect For each character that is set |\char_count| is incremented.
+If a character is a tabulator, we set with |\print_tab| the fitting
+amount of blank characters, otherwise the character itself.  We must
+compare the character that is stored in |\@char| with a macro of which
+the ``first-level'' expansion is an active tabulator.  For this case
+we declare |\@tab|.
+
+\beginprog
+{\obeytabs\gdef\@tab{^^I}}
+
+\def\print_first_char#1{%
+   \def\@char{#1}%
+   \advance \char_count\@ne
+   \ifx \@char\@tab  \print_tab
+   \else  \@char
+   \fi
+   }
+\endprog
+
+
+\sect If we want to fill the line with blank spaces up to the next
+column with a number that can be divided by~8, we must be able to
+compute the column number modulo~8, but \TeX{} has no modulo operator.
+So we define the macro |\mod_viii| that computes its argument modulo~8
+and returns the result in the counter |\count_mod_viii|.  For the
+computation we need the temporary counter |\count@|.
+
+\beginprog
+\newcount\count_mod_viii
+\def\mod_viii#1{%
+   \count@ #1\relax  \count_mod_viii\count@
+   \divide \count@ 8\relax
+   \multiply \count@ 8\relax
+   \advance \count_mod_viii -\count@
+   }
+\endprog
+
+
+\sect Now we can declare |\print_tab|.  We must remember that
+|\char_count| was incremented already, if we set only one blank
+character the counter keeps untouched.
+
+\beginprog
+\def\print_tab{%
+   \loop  \space \mod_viii\char_count
+      \ifnum \count_mod_viii>\z@
+         \advance \char_count\@ne
+   \repeat
+   }
+\endprog
+
+
+\sect If the rest of the line is empty, we are ready.  |\char_count|
+is reset to~1 for the next line.
+
+Inside the |\else| part of |\ifx| |\print_char| should not be used
+directly because this costs too much storage of \TeX{}.  Instead we
+set a control sequence |\next| that is processed afterwards, depending
+on the result of the comparison.  If there is still something to set,
+we use |\print_char| again, otherwise a syntactically similar macro
+that expands to |\relax|.
+
+\beginprog
+\def\print_rest_of_line#1{%
+   \def\@line{#1}%
+   \ifx \@line\empty  \char_count\@ne
+        \def\next##1\end_line{\relax}%

+\chap Document Structuring.
+
+The layout of the document shall be like in \WEB{}.  This can be done
+easily in Plain.  If \LaTeX{} shall be used for the document
+preparation, this part of the macro must be eliminated.  It will also
+be better to include the program parts \LaTeX-like as an environment
+between |\begin{prog}| and |\end{prog}| and to define control
+sequences |\makebaractive| and |\makebarother| for the switch of the
+special meaning of the vertical bar (`{\tt \origvert\/}') (for the
+{\tt tabular\/} environment!)
+
+All sections are enumerated, the number of the next section is stored
+in the counter |\sectno|.  We differenciate between main sections
+which start a group of sections and between normal sections within a
+group.
+
+\beginprog
+\newcount\sectno  \sectno=\@ne
+\endprog
+
+
+\sect The main sections are started with the macro |\chap| that has
+one parameter, the title of the section group.  This parameter must be
+terminated by a dot.  We start a new page, typeset the title in bold
+face and separate it from the section text with a |\medskip|.  This
+text, the documentation part of the section, is formatted without
+paragraph indentation.
+
+The deletion of the paragraph indentation is done with |\everypar|.
+We do not care if |\everypar| is used for something else and delete it
+after usage.
+
+The section number is marked to appear {\it via\/} |\topmark| in the
+headline, the title goes as a running head into the headline too. The
+section number is displayed on the terminal as a progress report, and title,
+section and page number are recorded in the contents file.

+\chap Formatting.
+The macros in this chapter are extracted from \.{WEBMAC.TEX}, while most of
+the documentation is taken from Appendix~G of the ``\.{WEB} User Manual''.
+The macros in \.{docmac} make it possible to produce a variety of formats,
+and the purpose of this appendix is to explain some of the possibilities.
+Displayed examples, that are included in the documentation, come out centered
+to distinguish them from program text, which is flushleft.
+
+\def\lpile{\def\cr{\hfill\endline}\matrix} % I [D E Knuth] only use \lpile by itself

+\sect We begin the formatting part with some declarations that should make
+look the output a little better for documenting programs.
+
+\beginprog
+\parskip 0pt % no stretch between paragraphs
+\parindent 1em % for paragraphs and for the first line of Pascal text
+\endprog
+
+\sect Three fonts have been declared in addition to the standard fonts of
+\.{PLAIN} format: You can say `\.{\{\\sc stuff\}}' to get {\sc stuff}
+in small caps; and you can select the largish fonts \.{\\titlefont}
+and \.{\\ttitlefont} in the title of your document, where \.{\\ttitlefont}
+is a typewriter style of type.
+
+\beginprog

+\endprog
+
+\sect You can say `\.{\\\\\{identifier\}}' to set \\{identifier} in
+italics.
+
+To get typewriter-like type, as when referring to `\.{WEB}', you
+can use the `\.{\\.}' macro (e.g., `\.{\\.\{WEB\}}'). In the argument to
+this macro you should insert an additional backslash before the symbols
+listed below, i.e.,
+before backslashes and dollar signs and the like.
+A `\.{\\\ }' here will result in the visible space symbol; to get an

+\endprog
+
+\sect The three control sequences \.{\\pagewidth}, \.{\\pageheight},
+and \.{\\fullpageheight} can be redefined in the limbo section at the
+beginning of your source file, to change the dimensions of each page.
+The standard settings
+$$\lpile{\.{\\pagewidth=6.5in}\cr
+  \.{\\pageheight=8.7in}\cr
+  \.{\\fullpageheight=9in}\cr}$$
+were used to prepare the present report; \.{\\fullpageheight} is
+\.{\\pageheight} plus room for the additional heading and page numbers at
+the top of each page. If you change any of these quantities, you should
+call the macro \.{\\setpage} immediately after making the change.
+
+The \.{\\pageshift} macro defines an amount by which right-hand
+pages (i.e., odd-numbered pages) are shifted right with respect to
+left-hand (even-numbered) ones. By adjusting this amount you may be
+able to get two-sided output in which the page numbers line up on
+opposite sides of each sheet.
+
+\beginprog
+\newdimen\pagewidth \pagewidth=6.5in % the width of each page
+\newdimen\pageheight \pageheight=8.7in % the height of each page
+\newdimen\fullpageheight \fullpageheight=9in % page height including headlines
+\newdimen\pageshift \pageshift=0in % shift righthand pages wrt lefthand ones
+\def\magnify#1{\mag=#1\pagewidth=6.5truein\pageheight=8.7truein
+  \fullpageheight=9truein\setpage}
+\def\setpage{\hsize\pagewidth\vsize\pageheight} % use after changing page size
+\endprog
+
+\sect The \.{\\title} macro will appear at the top of each page
+in small caps. For example, this document was produced after saying
+`\.{\\def\\title\{DOCMAC\}}'.
+
+\beginprog
+\def\lheader{\mainfont\the\pageno\eightrm\qquad\rhead\hfill\title\qquad
+  \tensy x\mainfont\topmark} % top line on left-hand pages
+\def\rheader{\tensy x\mainfont\topmark\eightrm\qquad\title\hfill\rhead

+      \vfill#1}} % parameter #1 is the page itself
+  \global\advance\pageno by1}
+
+\def\rhead{\.{DOCMAC} OUTPUT} % this running head is reset by starred sections
+\def\title{} % an optional title can be set by the user
+\endprog
+
+\sect The first page usually is assigned page number 1.
+To start on page 16, with contents
+on page 15, say this: `\.{\\def\\contentspagenumber\{15\}}
+\.{\\pageno=\\contentspagenumber} \.{\\advance\\pageno by 1}'.
+
+\beginprog
+\def\contentspagenumber{0} % default page number for table of contents
+\endprog
+
+\sect The macro \.{\\iftitle} will suppress the header line if it is
+defined by `\.{\\titletrue}'. The normal value is \.{\\titlefalse}
+except for the table of contents; thus, the contents
+page is usually unnumbered.
+
+Two macros are provided to give flexibility to the table of
+contents: \.{\\topofcontents} is invoked just before the contents
+info is read, and \.{\\botofcontents} is invoked just after.
+For example, you can define:
+$$\lpile{\.{\\def\\topofcontents\{\\null\\vfill}\cr
+  \.{ { }\\titlefalse \% include headline on the contents page}\cr
+  \.{ { }\\def\\rheader\{\\mainfont Appendix D\\hfil 15\}}\cr
+  \.{ { }\\centerline\{\\titlefont The \{\\ttitlefont WEAVE\}{ }processor\}}\cr
+  \.{ { }\\vskip 15pt \\centerline\{(Version 4)\}{ }\\vfill\}}\cr}$$
+Redefining \.{\\rheader}, which is the headline for right-hand pages,
+suffices in this case to put the desired information at the top of the
+contents page.
+
+\beginprog
+\newif\iftitle
+
+\def\topofcontents{\centerline{\titlefont\title}
+  \vfill} % this material will start the table of contents page
+\def\botofcontents{\vfill} % this material will end the table of contents page
+\endprog
+
+\sect Data for the table of contents is written to a file that
+is read when |\contentspage| is called; there's one line of data
+for every starred module. For example, when this document was being created, a
+file \.{DOCMAC.TOC} containing
+$$\lpile{\.{\\Z \{{ }Introduction\}\{1\}\{1\}}\cr
+  \.{\\Z \{{ }Local Verbatim Formatting\}\{3\}\{2\}}\cr}$$
+and similar lines was created. The \.{\\topofcontents} macro could
+redefine \.{\\Z} so that the information appears in another format.
+
+\beginprog
+\def\contentsfile{\jobname.toc} % file that gets table of contents info
+\def\readcontents{\expandafter\input \contentsfile}
+
+\newwrite\cont
+\output{\setbox0=\page % the first page is garbage
+  \openout\cont=\contentsfile
+  \global\output{\normaloutput\page\lheader\rheader}}
+\setpage
+\vbox to \vsize{} % the first \topmark won't be null
+
+\def\con{%
+  \write\cont{} % ensure that the contents file isn't empty
+  \closeout\cont % the contents information has been fully gathered
+  \par\vfill\eject % finish the preceding page
+   \rightskip 0pt \hyphenpenalty 50 \tolerance 200
+  \setpage
+  \output{\normaloutput\page\lheader\rheader}
+  \titletrue % prepare to output the table of contents
+  \pageno=\contentspagenumber \def\rhead{TABLE OF CONTENTS}
+  \message{Table of contents:}
+  \topofcontents
+  \line{\hfil Section\hbox to3em{\hss Page}}
+  \def\Z##1##2##3{\line{\ignorespaces##1
+    \leaders\hbox to .5em{.\hfil}\hfil\ ##2\hbox to3em{\hss##3}}}
+  \readcontents\relax % read the contents info
+  \botofcontents \end} % print the contents page(s) and terminate
+\let\contentspage=\con
+\endprog
+
+\sect Sometimes it is necessary or desirable to divide the output of
+\.{docmac} into subfiles that can be processed separately. For example,
+the listing of \TeX\ runs to more than 500 pages, and that is enough to
+exceed the capacity of many printing devices and/or their software.
+When an extremely large job isn't cut into smaller pieces, the entire
+process might be spoiled by a single error of some sort, making it
+necessary to start everything over.
+
+Here's a safe way to break a docmac'ed file into three parts:
+Say the pieces are $\alpha$,
+$\beta$, and $\gamma$, where each piece begins with a starred module.
+All macros should be defined in the opening limbo section of $\alpha$,
+and copies of this \TeX\ code should be placed at the
+beginning of $\beta$ and of $\gamma$. In order to process the parts
+separately, we need to take care of two things: The starting page
+numbers of $\beta$ and $\gamma$ need to be set up properly, and
+the table of contents data from all three runs needs to be
+accumulated.
+
+The \.{docmac} macros include two control sequences \.{\\contentsfile} and
+\.{\\readcontents} that facilitate the necessary processing.  We include
+`\.{\\def\\contentsfile\{CONT1\}}' in the limbo section of~$\alpha$, we
+include `\.{\\def\\contentsfile\{CONT2\}}' in the limbo section of~$\beta$,
+and we include `\.{\\def\\contentsfile\{CONT3\}}' in the limbo section
+of~$\gamma$; this causes \TeX\ to write the contents data for
+$\alpha$,~$\beta$, and~$\gamma$ into \.{CONT1.TEX}, \.{CONT2.TEX}, and
+\.{CONT3.TEX}. Now in~$\gamma$ we say $$\.{\\def\\readcontents\{\\input CONT1
+\\input CONT2 \\input CONT3\}};$$ this brings in the data from all three
+pieces, in the proper order.
+
+However, we still need to solve the page-numbering problem. One way to
+do it is to include the following in the limbo material for $\beta$:
+$$\lpile{\.{\\message\{Please type the last page number of part 1: \}}\cr
+  \.{\\read -1 to \\temp \\pageno=\\temp \\advance\\pageno by 1}\cr}$$
+Then you simply provide the necessary data when \TeX\ requests
+it; a similar construction is used at the beginning of $\gamma$.
+
+This method can, of course, be used to divide a docmac'ed file into
+any number of pieces.
+
+\sect The counter \.{\\sectno} is set to the number of the
+module being typeset.
+
+\sect We are finished and just have to restore the category codes.
