% \section{Introduction}
% A problem facing users of \btx{} is that there is no standard for
% formatting lists of references. Publishers and journals insist
% on completely arbitrary placement of commas, colons, and ordering of
% entries. Furthermore, author--year styles of citations are supported by
% certain special \LaTeX{} packages, but each for only a very limited
% number of bibliographic styles. Finally, most such style files are for
% English only, and any adaptations to other languages must duplicate the
% entire spectrum of such files.
%
% All of these obstacles are in principle easily overcome by simply
% reprogramming \btx{} by means of an appropriate \emph{bibliographic style
% file} (extension \texttt{.bst}). \btx{} is in fact extremely flexible;
% unfortunately its programming language is very low-level, permitting only
% the most basic of hacks for the normal user.
%
% The solution to this is a \emph{generic} or \emph{master bibliographic
% style file} (extension \texttt{.mbs}) containing \dtx{} options for
% alternative coding. By selecting the desired options, one can customize a
% \texttt{.bst} file to one's needs.
%
% This file, \texttt{\filename}, is my latest version of a general-purpose
% \texttt{.mbs} file to meet as many bibliographic needs as possible.
% It was originally assembled from Oren Patashnik's standard files {\tt
% plain.bst} and \texttt{unsrt.bst}, plus his non-standard file {\tt
% apalike.bst}, a very basic author--year citation style.
% It has since evolved extensively as I have added features found in
% available \texttt{.bst} files, and those demanded by publishers or
% suggested to me by many user/contributors.
%
% To produce a customized bibliographic style (\texttt{.bst}) file from this
% master file, simply \TeX{} or \LaTeX{} the `program' \texttt{makebst.tex}.
% When asked for the name of the master file, answer with
% \begin{quote}\tt\filename\end{quote}
% and then reply to the questions in the following menus. The last question
% is whether you want to generate the \texttt{.bst} file right away.
%
% More details on this process and on the options available are to be found
% in the rest of this article.
%
% \section{History of this File}
%
% Since the first release of this generic file, in November 1993, under the
% name \texttt{genbst.mbs}, I have received innumerable
% suggestions for additions, most of which I have tried to include. Often
% this has resulted in reorganizing the coding, and adding new functions.
% The resulting \texttt{.bst} files are now quite different from those of
% Patashnik, although the underlying ideas are the same.
%
% A second version was released shortly afterwards that paralleled the first
% one except that it included support for languages other than English.
% That file was named \texttt{babel.mbs}, following the \texttt{babel}
% system of Johannes Braams. Although I always viewed it as version 2 of
% \texttt{genbst.mbs}, all additions to the one were also included in the
% other. This of course was tedious and prone to error. I looked forward to
% the day when \texttt{babel.mbs} would become the only supported version.
% The reason I was reluctant to do that before was that the overhead per
% language was fairly high, and I dreaded to think how large the file would
% become when 20 or 30 languages were added.
%
% I have now found a way to put the language definitions into separate files,
% one per language. This means that new languages do not burden the basic
% file, and that users need only keep those support files that might
% interest him or her. New ones may also be made up locally by hacking an
% existing language definition file. (The file \texttt{english.mbs} is
% supplied only for this purpose.)
%
% For this reason, \texttt{\filename} is released as version~3 of
% \texttt{genbst.mbs} and \texttt{babel.mbs}. In spite of the new name, it
% should be regarded as their direct successor. Needless to say, this means
% that the earlier two \texttt{.mbs} files will no longer be maintained.
%
% To include language support, all explicit English words like
% \textsl{editor} and \textsl{chapter} have been replaced by functions
% whose definitions may be altered in the resulting \texttt{.bst} file
% (less desirable method) or which may be redefined by an external
% language definition file (preferred method). Alternatively, one can select
% the pseudo-language named \texttt{babel} which inserts \LaTeX{} commands
% for the explicit words, the definitions of which must be
% contained in a file called {\tt babelbst.tex}. Only the languages English
% and \texttt{babel} are included internally to \texttt{\filename}; all
% others are contained in external language definition files.
%
% Another new feature is the possibility of including a file containing
% prestored shorthand designations for certain journal names. Such a file
% is provided for physics journals, but others could be made up using this
% one as a model. See Section~\ref{sec:jnames}.
%
% To take advantage of these external files, one must use
% \texttt{makebst} version~3; \texttt{\filename} may still be used with
% earlier versions, but without the external files.
%
% \def\temp{merlin.mbs}\ifx\temp\filename
% This file is now named after the legendary magician in the hope that it
% can produce wonders by incanting the right magic formulas. However, one
% should bear in mind that even Merlin was not omnipotent. It would be too
% much to hope that all bibliographic wishes will be fulfilled quickly and
% easily, but we shall try as best we can. Watch the wizardry at work!
% \fi
%
% \section{About Master Bibliographic Style Files}
%
% For details about how master bibliography style files are to be
% constructed, see the documentation on \texttt{makebst}. Here only a
% rough overview is given.
%
% \subsection{The \dtx{} Program}
% The \dtx{} program, written by Frank Mittelbach, is now a fundamental
% part of the \LaTeXe{} installation. Its original purpose is to remove
% comment lines from documented files, but has the secondary function of
% selecting alternative lines of coding.
%
% A master \btx{} bibliographic style file is one that, when processed by
% \dtx{} with selected options, produces a regular \btx{} \texttt{.bst}
% file with the desired features.
%
% In this sense, \dtx{} functions something like a C preprocessor. In fact,
% Oren Patashnik's original \texttt{.bst} files were all produced from a single
% source file by means of the preprocessor. The advantage of \dtx{} is that
% it is portable to all installations with \TeX.
%
% \subsection{The \dtx{} Batch Job}
%
% The \dtx{} program can be run either interactively, where the user must
% answer questions via the keyboard, or by means of a batch job where all
% the inputs are prepared in a file beforehand. For producing a \btx{}
% style file from a master file, the batch job method is the only feasible
% one, simply because of the large number of options available. (There is
% another reason for employing a batch job: the interactive method adds an
% |\endinput| command at the end, something that \btx{} will protest
% about.)
%
% The batch job files in general do not have any particular extension but I
% use \texttt{.dbj} for \emph{\dtx{} batch job}. These files are useful
% because they document the options used to produce the \texttt{.bst} file,
% and they may be edited to experiment with alternative options.
%
% \subsection{The \texttt{makebst} Program}
%
% It is possible to make up a batch job file by hand using the option
% information listed in Section~\ref{sec:options}, but my accompanying
% program \texttt{makebst} simplifies the task considerably. It reads menu
% information in the master file itself in order to present the user with
% an interactive list of choices, translating the answers into appropriate
% options that are then written to a batch job file.
%
% To run it, simply process \texttt{makebst.tex} with \TeX\ or \LaTeX, and
% answer the questions. The first of these is whether you want some
% instructions or not, and the second is the name of the \texttt{.mbs} that
% you want to use. The next query is about the name of the desired
% \texttt{.bst} file (which will also be the root name of the batch job).
% After that, all further questions come from menu information in the
% master file.
%
% At the very end, \texttt{makebst} asks if it should run the batch job for
% you. Isn't that a fine service?
%
% \section{Multilingual Adaptation}
% The original \texttt{.bst} files from Oren Patashnik contain explicit
% English words that are output into the final text. Since \LaTeX{} is
% increasingly being used for other languages, and since the official
% version since December 1991 also uses macros in place of explicit words,
% it seems appropriate for \btx{} to follow suit.
%
% In this master bibliographic style file {\tt\filename}, all explicit
% words have been replaced by functions: e.g., the word \textsl{editor} has
% become the function \texttt{bbl.editor}. Depending on the language option
% chosen, this function is defined to be the text {\tt"editor"},
% {\tt"Redakteur"}, or {\tt"redacteur"}, for English, German, and French,
% respectively.
%
% There is another special `language' called \texttt{babel} that instead inserts
% the text |"\bbleditor{}"|; the definitions of these \LaTeX{} commands
% must be in a separate file named \texttt{babelbst.tex} that is read in at
% the start of the bibliography.
%
% Only English and \texttt{babel} are supported directly in
% \texttt{\filename}; all other language definitions are contained in
% separate definition files, e.g., \texttt{french.mbs}, \texttt{german.mbs}.
%
% The language selection is made during the \texttt{makebst} run, which
% asks for the name of the language definition file as the first menu item. If
% either English or \texttt{babel} is wanted, reply with the default, which
% is \texttt{\filename} itself; otherwise give the name of the desired
% language file.
%
% \begin{quote}\slshape
% \textbf{Note:} the language definition files can only be used with
% \texttt{makebst} version~3 or later, and
%
% with an external definition file, the \dtx{} run requires two passes
% through \texttt{\filename}, doubling the processing time.
% \end{quote}
%
% \subsection{Adding a New Language Definition File}
%
% To create a new language definition file, simply take one of the existing
% ones, like \texttt{english.mbs}, and replace the explicit English words
% with their translations. There are, however, a number of points that can
% complicate this procedure.
%
% \begin{enumerate}
% \item
% Do not forget to change the documentation in the file, especially
% version number, date, author.
%
% \item
% There are option menus that need to be translated too. It might also be
% desirable to add or remove options. In most cases, the options in the
% language files involve possible abbreviations, like
% \begin{quote}
% \verb!\mes{^^JABBREVIATE WORD `PAGES':}!\\
% \verb!\optdef{*}{}{`Page(s)'}{(no abbreviation)}!\\
% \verb!\optdef{a}{pp}{`Page' abbreviated}{as p. or pp.}!\\
% \verb!\getans!
% \end{quote}
%
% In this example, the option \texttt{pp} appears later in the definition
% \begin{quote}
% \verb!FUNCTION {bbl.pages}!\\
% \verb+%<!pp>{ "pages" }+\\
% \verb!%<pp>{ "pp." }!
% \end{quote}
% This a \emph{local} option, that only affects the coding in the definition
% file. It is possible to add more local options.
%
% \item
% However, all options, whether activated by the main file or by the
% definition file, apply to both. In other words, there really is no such
% thing as a local option. In the above example, \texttt{pp} is only
% local because it is never used in \texttt{\filename}.
%
% \item
% Add the name of the language as an option, with
% \begin{quote}
% \verb!\mes{^^JOptions for ENGLISH}!\\
% \verb!\wr{\spsp\spsp\sep english\pc: English language}!
% \end{quote}
% (This is how options are added without |\optdef| and |\getans|.) The
% main file just might recognize it in order to take some
% language-specific action. The least it should do is add a comment at
% the start of the \texttt{.bst} file stating for which language it is to
% be used.
%
% \item
% There could be some problems with edition numbers due to language
% dependent ways of treating ordinal numbers (1st, 2nd, 3rd in English;
% 1$^{\mbox{\scriptsize re}}$, 2$^{\mbox{\scriptsize e}}$,
% 3$^{\mbox{\scriptsize e}}$ in French; 1., 2., 3., in German). Some
% accommodation already exists for the oddball language English, and
% further hacking may be needed for others.
%
% \item
% If there should be any need for a double-quote character in
% the translations (German needs it for umlauts) then there is trouble
% because the \btx{} strings do not allow it. Instead, use the command
% |\qq|, as in the German word |F\qq{u}nfte| for {\sl F\"unfte} (fifth).
% It is then vital to add the option \texttt{umlaut} with
% \begin{quote}
% \verb!\wr{\spsp\spsp\sep umlaut\pc: Activate umlaut command}!
% \end{quote}
%
% Bernd Raichle points out that |\^^b| can be used in place of |\"|
% within \btx{} code. One can thus replace |F\qq{u}nfte| with |F\^^b unfte|
% and do away with the \texttt{umlaut} option.
%
% \end{enumerate}
%
% \subsection{Changing \texttt{babelbst.tex} for a New Language}
%
% Alternatively, a new language can be added by
% modifying the file \texttt{babelbst.tex} and selecting the language {\tt
% babel} for the \texttt{.bst} file. If this is the only language to be used,
% then just change the English words in the definitions.
%
% However, some form of switching would be more desirable. With \TeX\
% version 3, there is a |\language| parameter to control the hyphenation
% patterns, and this could be used to select the correct language. For
% example, if language 0 is English and language 1 German, then put the
% English version of \texttt{babelbst.tex} into \texttt{englbst.tex} and the
% German
% version in \texttt{germbst.tex}. Then \texttt{babelbst.tex} could contain:
% \begin{quote}\begin{verbatim}
% \ifcase\language \input{englbst} \or \input{germbst}
% \else \input{englbst} \fi
% \end{verbatim}
% \end{quote}
%
% This is of course installation dependent.
%
% \subsection{Extracting the Sample \texttt{babelbst.tex} File}
%
% A sample \texttt{babelbst.tex} (for English) is contained in this master
% file. Extract it with \dtx{} and the option \texttt{bblbst}. It may be
% edited (and possibly renamed) for other languages as needed.
%
% \subsection{Problem with Edition Numbers}
% Something to note here is the ordinal numbers for editions. \btx{}
% demands that the field \texttt{edition} be given in the database as a word
% \textsl{First}, \textsl{Second}, etc., or as \textsl{1st}, \textsl{2nd},
% etc. This is bad policy
% because it is language dependent. So what I do is to test for the words
% \textsl{first} through \textsl{fifth} (case independently) and replace them
% with language-dependent equivalents. If the {\tt<ord>} option is selected,
% these equivalents are ordinal numbers for that language. Any other words
% cannot be interpreted and must be printed as is.
%
% However, if the \texttt{edition} is given as a number, with or without
% following letters, then the numbers 1 through 5 are replaced by their
% words; any higher numbers just have the ordinal ending (\textsl{th}
% in English) added to them.
%
% These numbers are only used with the word \textsl{edition} or
% its equivalent in other languages, so the translators need

% French.
%
% \section{Prestoring Names of Journals}\label{sec:jnames}
%
% The standard \texttt{.bst} files contain the names of some 20 journals
% in the field of computing, stored as macros for easy reference within the
% database \texttt{.bib} files. For example, the \textsl{Journal of
% Computer and System Sciences} can be referred to as \texttt{jcss}.
% With the option \texttt{jabr} (for journal abbreviation) this same
% shorthand produces \textsl{J.~Comput. Syst. Sci.}.
%
% Some \texttt{.bst} files for physics journals include additional journal
% names, and it is conceivable that other faculties might wish to prepare
% their own such lists, with each name present in a full or abbreviated
% form. Such an external file can now be added with \texttt{\filename} and
% \texttt{makebst} version~3.
%
% As a model, I supply a file \texttt{physjour.mbs} with the names of
% physics journals which I have taken from other \texttt{.bst} files.
% I also have a contributed file \texttt{photjour.mbs} containing names of
% optics journals.
%
% In fact, version~3.5 can even include multiple journal-name files.
% Thus one can decide whether to include both, one, or none of the above
% files.
%
% \section{Updating Older \texttt{.dbj} Files}\label{sec:update}
% If you have existing \texttt{.dbj} files for generating \texttt{.bst}
% files from the older version \texttt{genbst.mbs}, these may be run with
% \texttt{\filename} by simply changing the name of the source
% \texttt{.mbs} file. For example, where the older \texttt{.dbj} file contains
% the line
% \begin{quote}
% |\generateFile{mystyle.bst}{f}{\from{genbst.mbs}{%|
% \end{quote}
% edit the file so that \texttt{genbst.mbs} is replaced by
% \texttt{\filename}. The resulting \texttt{mystyle.bst} file will then be
% an updated version of the older one, containing all the same features.
%
% \section{Acknowledgements}
% I wish to thank all the people who have taken the trouble to send me
% suggestions or special requests. Admittedly, it has been out of
% self-interest on their part, since they had bibliographic needs to be
% met. And I have often questioned the need for many of their demands. Yet,
% that is part of the bibliographic jungle that I am trying to eliminate.
% If I thought that bibliographies were arbitrarily formatted before I
% started this project, I have more than sufficient confirmation since
% then. The fault lies not with the poor contributors, but with the
% publishers who cannot agree on a decent standard.
%
% I especially want to thank Frank Mittelbach, not only for creating \dtx{}
% in the first place, but also for sending me his bibliographic requirements,
% and for suggesting an improvement to \texttt{makebst}.
%
% And finally, all of us must thank Oren Patashnik for providing \btx;
% without its flexibility and programmability (in spite of the complexity
% of the language) the master bibliographic styles would not be possible at
% all.
%
% \section{The Options}\label{sec:options}
% Here I present a list of all the \dtx{} options that are
% available in this file {\tt\filename}.
% The normal user can skip this section since he will probably make use
% of the menus via \texttt{makebst}. These are described in
% Section~\ref{sec:menu}. The menus provide much more informative prompts
% than the heavily abbreviated option names listed here. In other words,
% the options described in this section are meant for internal (programmer)
% usage, while the normal interface for the user is the menus.
%
% I have tried to avoid
% conflicts with mutually exclusive options by always letting one dominate if
% more than one has been specified. Such options have the same prefix, such
% as \texttt{nm-rev} and \texttt{nm-init}.
% If one uses \texttt{makebst} to produce the
% \dtx{} batch job, then it is impossible to give mutually
% exclusive options unless one edits the batch file oneself afterwards.
% (Anything is possible with computer freaks!)
%
% Most mutually exclusive options have the same prefix before the hyphen.

% \begin{opt}
% \item[--] default is numerical, standard \LaTeX, as for {\tt

% but an abbreviation of the author names plus year is used as
% the label.

%
% \section{The Menu Information}\label{sec:menu}
% Here I describe the options and menu information for this particular
% master file \texttt{\filename}. To construct a \dtx{} driver file
% to generate a desired \texttt{.bst} file, simply process \texttt{makebst.tex}
% with \TeX\ or \LaTeX, and give
% \begin{quote}\tt\filename\end{quote}
% when prompted for the name of the master file. Then answer the questions
% in the menus that follow. The menu information is extracted from here.
%
% All the menu information is nested between \dtx{} guard options
% |%<*options>| \dots\ |%</options>|, and the last command is
% |\endoptions|. The rest of the file is nested between
% \begin{quote}
% |%<*!options&!driver&!bblbst>| \dots\ |</!options&!driver&!bblbst>|
% \end{quote}
% in order to exclude it if \dtx{} is used to
% extract the menu information, the documentation driver, or the
% \texttt{babelbst.tex} file.
%
% The main coding is divided into two sections, the \emph{head} and
% \emph{tail}; in between come any external language or journal name
% support files. The head part is marked with the \dtx{} guard option
% |<!tail>| and the tail with |<!head>|. This roundabout means of doing
% things makes it possible to process \texttt{\filename} with \texttt{.dbj}
% files that were generated for the older \texttt{genbst.mbs} file by
% simply changing the name of the source file as shown in
% Section~\ref{sec:update}. If both \texttt{head} and \texttt{tail} (and
% \texttt{exlang}) options are omitted, as they are in the older
% \texttt{.dbj} files, \texttt{\filename} is processed completely in one
% pass. To include external files, two passes are needed, one for each
% part, with the external file(s) coming in between.
%
% Note too that if the internal language commands are taken (i.e., if
% \texttt{exlang} option is not given) then the default language is
% English, which is tested for as |<!babel>|. This too permits the simple
% update of older \texttt{.dbj}, at least for English.
%
% \subsection*{Selecting Language}
% Explicit words in the bibliography style, such as \textsl{and},
% \textsl{editor}, etc.,
% are represented by functions \texttt{bbl.and}, \texttt{bbl.editor}, and so on.
% By default these functions translate to the normal English text, but
% other languages are also possible.
%
% The definitions of these functions for other languages are contained in
% external files. At this point, we can make use of features in
% \texttt{makebst} (version~3.0 or later) to ask for the name of such a
% definition file, and store it in |\cfile|. If no external file is
% specified, then the internal definitions are taken, for which there are
% two possibilities: English or \LaTeX{} commands (Babel).
%
% The commands |\MBswitch|, |\mes|, |\MBaskfile|, |\wr|, |\pc|, |\spsp| are
% defined in \texttt{makebst.tex}.
%
% If |\MBswitch| does not exist, then the version of \texttt{makebst}
% cannot support external files.
%
% \begin{macrocode}

% \end{macrocode}
%
% A second type of external file that can be added is one containing names
% of journals that are to be prestored into the \texttt{.bst} file.
% Several file names are allowed here, with the root names separated by
% commas, and with the common extension added at the end. To assist later
% parsing of the names, an additional comma is added before the extension.
%
% Note that in this case |\MBaskfile| treats the file(s) as output, i.e.,
% it does not check if the file(s) actually exist.
%
% The macro |\Mgetnext| allows the root names to be extracted from the
% list of file names.

% If no external files are specified, then both |\cfile| and |\jfile| are
% empty. In this case, do \emph{not} set the options \texttt{head} and
% \texttt{tail}, which control the \dtx{} passes through
% \texttt{filename}. Now only one pass is made.
%
% If there is an external definition file, or if an external list of
% journal names, then some extra text must be
% written to fit in with that already written by \texttt{makebst}. This is
% explained in that documentation. The |\MBswitch| command turns the curly

%
% \subsection*{Author--year or numerical}
% The first question is whether a numerical or author--year citation style
% is to be used. If the latter, the supporting system is my {\tt
% natbib.sty}, which expects |\bibitem| to have an optional argument
% containing the short form of the authors, plus year in parentheses.
% E.g.,
% \begin{quote}
% |\bibitem[Daly et al.(1990)]{key}...|
% \end{quote}
% There is now a newer version of \texttt{natbib.sty} (v5.3) that
% supports an optional full author list too, as
% \begin{quote}
% |\bibitem[Daly et al.(1990)Daly, Keppler, and Williams]{key}...|
% \end{quote}
% Other systems are also supported, such as the Harvard family of
% bibliography styles (with \texttt{harvard.sty}), which have entries in the
% form
% \begin{quote}
% |\harvarditem[Daly et al.]{Daly, Keppler,|\\
% | and Williams}{1990}{key}...|
% \end{quote}
% or the astronomy family (with \texttt{astron.sty}) with entries like
% \begin{quote}
% |\bibitem[\protect\astroncite{Daly et al.}{1990}]{key}...|
% \end{quote}
% or the Chicago family (with \texttt{chicago.sty}) with entries like
% \begin{quote}
% |\bibitem[\protect\citeautheryear{Daly, Keppler, and|\\
% | Williams}{Daly et al.}{1990}]{key}...|
% \end{quote}
% or the `named' variant of Chicago (with \texttt{named.sty}) with entries like
% \begin{quote}
% |\bibitem[\protect\citeauthoryear{Daly et al.}{1990}]{key}...|
% \end{quote}
% or the so-called ``author--date'' group (with \texttt{authordate1-4.sty})
% with entries of the form
% \begin{quote}
% |\bibitem[\protect\citename{Daly et al.}1990]{key}...|

% \subsection*{Ordering of the listed references}
% Choices here depend on citation style. The default in both cases is
% alphabetical order of all authors. For numerical style, one may also
% choose an unsorted order, which means the order is the same as the original
% citations. This corresponds to \texttt{unsrt.bst}. Order of citation is
% also offered for author--year for \texttt{natbib}-type styles that can
% also be used for numerical listings.
%
% Another possibility is to order first by year, then authors. This too only
% makes sense for numerical citations. However, it is offered for author--year
% in the event that a \texttt{natbib}-type style is used for numerical
% listings.
%
% For the alpha style, the ordering is by label only, so no option is
% offered here (|\ifnumerical| is \meta{true} and |\ifmytemp| is \meta{false}).
%
% For author--year, the second choice is by label. (The label is the
% optional |\bibitem| argument, and is what is printed in place of the
% |\cite| command.) With this option, all the papers with the same first
% author are ordered so that the one-author papers come first, followed by
% the two-author papers, followed by the multiple-author papers. This is a
% more sensible system for author--year citations, and is demanded by some
% journals (like JGR).
%
% One problem that can arise here is when two or more references have the
% same set of authors and year; normally they are then ordered by the
% title, ignoring initial words like \textsl{the} and \textsl{a}, with the
% letters a, b,
% c, \dots, added to the year. This can mean that a set of references with
% a natural sequence will be put into a different order. An alternative is
% to order them by the citation keyword instead of by title. This of course
% assumes that the keywords in this case reflect that natural sequence.

% \subsection*{Formatting author names}
% The default is that the full names of the authors are listed, given names
% first, unabbreviated. Of course, if only the initials have been given in
% the \texttt{.bib} file, then that is all that can appear in the list. Other
% possibilities are to use initials (even if full names in the \texttt{.bib}
% file) either before or after the surnames. A specialty of the journals of
% the American Geophysical Union is to have only the first name with
% reversed initials.
%
% If the reference is part of a larger work with editors, then the editor
% names appear later in the reference text, usually as ``edited by \dots''
% or as ``\emph{names} (editors)''. In these cases, the editor names are
% not usually reversed (surname first) even if the authors' names are.
% An option is provided to format such editor names exactly as the authors'.

% \subsection*{Block punctuation}
% Blocks are logical sections of the reference specification, such as the
% author block, the journal block, editor block, etc. These are normally
% separated by periods, but alternatively a comma may be used. Another
% choice is to use commas except after titles where a period is given.
%
% \LaTeX\ offers an \texttt{openbib} option, which means that the blocks
% are not only new sentences, but new lines as well. This can only
% function when the default option here is taken, for then the command
% |\newblock| is placed between the blocks. This command is normally
% defined to do nothing, but \LaTeX\ redefines it to issue a new line
% when open bibliographies are wanted.

% If a font is selected for the cited authors, then the word `and' may be

%
% A variable \textsl{and} may be provided for with the command |\BIBand|

%
% \subsection*{Define emphasis}
% In everything that been mentioned so far, italicization should be
% understood to mean `emphasize' in the \LaTeX{} sense. This means that the
% command |\em| is used. This is not the same as |\it|, which is always
% italics. Rather, with |\em|, the font style switches between |\rm| and
% |\it| depending on the context. Here one may choose to true italics, or
% to switch off italics altogether.
% \begin{macrocode}

% \end{macrocode}
% \subsection*{New Font Selection Scheme}
% Bold face, italics, and emphasis are made with the \LaTeX~2.09 commands.
% This makes them compatible with \LaTeXe{} as well, but it is possible that
% in future they might die out. Also, they might not be provided with
% future classes. Allow an option to use the New Font Selection Scheme (NFSS)
% font commands in \LaTeXe. If this option is taken, then the \texttt{.bst}
% file may only be used with \LaTeXe.
% \begin{macrocode}
\mes{^^JNEW FONT SELECTION SCHEME:}

% \changes{3.0}{1995 Feb 27}{Option \texttt{nm-revf} to act just as default}
% When editors are used in place of authors to identify the work, the
% names are always formatted just like authors'. However, in collections,
% where ``edited by'' or ``\emph{names} (editors)'' are given, it is
% normal not the reverse the names, even if the authors' are. The option

% like those of authors, being reversed if necessary.
%
% The option \texttt{nm-revf} in this case acts the same as the default
% when no \texttt{nm-} option given: full names with surname last. Therefore
% it is not necessary to test for it at all, since it, like the default,
% has the lowest priority: any other \texttt{nm-} option clobbers it.
%
% The option \texttt{aunm-semi} will put a semi-colon between editor names, just

% In versions before 2.2, there were two functions \texttt{calc.long.label}
% and \texttt{format.long.lab.names} that made up the string
% \texttt{long.label} for each entry. This contains the full author list.

% \texttt{long.label} was limited to \texttt{entry.max\$} characters, 100 on
% my system. Author lists were truncated. Thus, \texttt{make.full.names}
% is used instead to enter the full list of names directly in the
% \texttt{output.bibitem} function, without an intermediate string. This
% involves changing the order of some function definitions, especially
% \texttt{output.bibitem} must come later.

% The option \texttt{vnum-dt} is most unpleasing. There should be more choice
% about how the number is formatted. It should be a separate option from
% the \texttt{vnum-} series, but it was a special wish. Option \texttt{jwdpg}
% is also part of this special wish. (Was not properly programmed until 3.81).
%
% The option \texttt{pp-last} is similar to \texttt{vnum-dt}, and might
% actually be able to replace it if used correctly with other options. But
% that is speculation on my part. What it does is to suppress the pages
% in the formatting macros, and sees to it that the pages are added just
% before any notes in those entries that take pages. This applies to more than
% just \texttt{article}, but to \texttt{inbook}, \texttt{incollection} as well.

% \changes{3.3}{1995 Aug 7}{Put extra label in braces}
% The extra label is added in braces so that natbib can treat it as one unit.
% This allows extra labels to be more than one letter long. For non-NFSS
% emphasizing, this is no problem, since labels go in |{\em a}|, but for
% non-emphasizing and for NFSS, it caused troubles without the braces.
% The trouble arises with multiple citations in one |\cite| in which
% authors and years are the same, and only the extra label is given for
% the next one. Note: |\emph{a}| is more than one letter long in this sense,
% so it is not just a problem for more than 26 papers with same authors and
% year.
%
% \changes{3.81}{1996 Jun 17}{Add \texttt{\char`\\natexlab}}
% The command |\natexlab| now encloses the extra label for \texttt{natbib}
% styles. This command normally just prints its argument, but for numerical
% citation mode, it swallows its argument. This allows the extra labels to
% be suppressed for numerical citations where they are superfluous.
