% \section{Introduction}
% This generic, or master, \btx{} style file is intended to be used with
% {\tt docstrip} in order to produce actual {\tt.bst} files. By selecting
% desired options, the output is customized to the particular requirements
% needed.
% The file has been assembled from Oren Patashnik's standard files {\tt
% plain.bst} and {\tt unsrt.bst}, plus his non-standard file {\tt
% apalike.bst}. This last is an author-year citation style, although
% somewhat imperfect. I have added a number of other options and codings to
% produce the features that I deem necessary.
% The file now contains the possibility of changing languages. All explicit
% words have been replaced by functions whose definitions may be altered in
% the resulting {\tt.bst} file (less desirable method) or for which optional
% definitions may be added in the master file as a new language option
% (preferred method). Alternatively, one can select the `language' named
% {\tt babel} and then \LaTeX{} commands are inserted for the explicit
% words, the definitions of which must be contained in a file called {\tt
% babelbst.tex}.
% To produce a customized bibliographic style ({\tt.bst}) file from this
% master file, simply \TeX{} or \LaTeX{} the `program' {\tt makebst.tex} or
% {\tt makebst.doc}. 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 {\tt.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{About Master Bibliographic Style Files}
% \subsection{The {\tt docstrip} Options}
% This master file is a \btx{} bibliographic style file containing
% alternative coding depending on {\tt docstrip} options. The options are
% selected when {\tt docstrip} is run, either interactively or through a
% batch job. 
% Suppose that one of the options is called {\tt xyz}. Then the following
% alternatives are possible:
% \begin{quote}
% |%<xyz> | \em one line of coding
% \end{quote}
% {\em includes\/} the single line of coding;
% \begin{quote}
% |%<!xyz> | \em one line of coding 
% \end{quote}
% {\em excludes\/} the single line;
% \begin{quote}
% |%<*xyz> | \\
% {\em several lines of coding}\\
% |%</xyz> | 
% \end{quote}
% {\em includes\/} all the bracketted lines;
% \begin{quote}
% |%<*!xyz> | \\
% {\em several lines of coding}\\
% |%</!xyz> | 
% \end{quote}
% {\em excludes\/} all the bracketted lines.
% Options may be logically combined: the symbol \verb!|! is a logical {\sf
% or}, |&| a logical {\sf and}, |!| a logical {\sf not}; parentheses {\tt(}
% and {\tt)} may be used to group options.
% \subsection{The {\tt docstrip} Batch Job}
% In order to generate a true \btx{} style file with selected options from
% this master file, it is necessary to run a {\tt docstrip} batch job.
% Suppose that the master file is named {\tt master.mbs}, and the
% resulting \btx{} style file is to be {\tt silly.bst}, and the batch job
% file itself is called {\tt silly.drv}. To produce this with options, say,
% {\tt xyz} and {\tt abc}, the batch job would look something like:
% \begin{quote}\begin{verbatim}
% \def\batchfile{silly.drv}
% \input docstrip
% \preamble
% This is for Journal of Silly Results
% \endpreamble
% \postamble
% End of customized bst file
% \endpostamble
% \keepsilent
% \generateFile{silly.bst}{f}{\from{master.mbs}{xyz,abc}}
% \end{verbatim}
% \end{quote}
% A preamble is not necessary, although it is advisable to include some
% statement about the application of the bibliographic style. A postamble
% {\em is\/} vital, otherwise the default will add |\endinput| at the end
% of the file, something that \btx{} will not understand. The |\keepsilent|
% is optional and just suppresses {\tt docstrip} output during processing.
% \subsection{The {\tt makebst} Program}
% The program {\tt makebst} simplifies the creation of the batch job file. To
% do that, it needs information on the available options. This information
% must be stored in a special format, either in the master file itself, or
% in a file with the same root name but extension {\tt.opt}. The form of
% this format is described in the documentation on {\tt makebst}.
% In the master file, this information must be enclosed within {\tt docstrip}
% options |%<*options>| \dots |%</options>| and {\em must\/} include an
% |\endoptions| command. It may also include any number of comments. 
% A sample menu in the master file to select one or none of options {\tt
% xyz} {\em or\/} {\tt zyx} would look thus:
% \begin{quote}\begin{verbatim}
% %<*options>
% \mes{Select one of these}
% \optdef{f}{xyz}{Option forword}{to do forward stuff}
% \optdef{r}{zyx}{Option reverse}{to do reverse stuff}
% \optdef{*}{}{None of the above}{}
% \getans
% \endoptions
% %</options>
% %<*!options>
% . . . . . . 
% %</!options>
% \end{verbatim}
% \end{quote}
% An explanation of these commands is to be found in the documentation on 
% {\tt makebst}.
% The menu information may be extracted from the master file by means of
% {\tt docstrip} and stored in a file with extension {\tt.opt}. If this
% file is missing, the program tries to read it from the master file.
% (I do not actually recommend doing this; the information should come
% from the true file and not from one that may have been edited)
% \section{Multilingual Adaptation}
% In the original {\tt.bst} files from Oren Patashnik, there are 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 `editor' has become
% the function {\tt 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 {\tt babel} that instead inserts
% the text |"\bbleditor{}"|; the definitions of these \LaTeX{} commands
% must be in a separate file named {\tt babelbst.tex} that is read in at
% the start of the bibliography.
% There are thus two ways of generating a {\tt.bst} file for a given
% language:
% \begin{enumerate}
% \item \label{one} 
%   Select one of the allowed {\tt docstrip} language options (see
%   page~\pageref{babelopt}) or {\tt makebst} language menu choices
%   (page~\pageref{babelmenu}) for a {\tt.bst} file that is valid for that
%   language only.
% \item \label{two}
%   Select the language {\tt babel} and then edit the file {\tt
%   babelbst.tex} to contain the desired translations, whereby 
%   a number of languages might be included in it with switching
%   according to some criterion.
% \end{enumerate}
% I am uncertain as to which is the better method. With \ref{one}, the
% {\tt.bst} file is complete on its own, but a different file must be
% generated for every language. This is probably necessary anyway since the
% bibliography style might be language dependent. Articles in English would
% have a different argument to the |\bibliographystyle| command from those
% in other languages. So what? Languages cannot really be switched so
% easily as an option in |\documentstyle|. The disadvantage is that the
% addition of further languages is somewhat complicated and the master file
% could grow to a very large size, slowing down the {\tt docstrip} processing.
% Method \ref{two} produces a single {\tt.bst} file for all languages, the
% differences appearing only in the file {\tt babelbst.tex}. This makes it
% easier to add new languages. However, unless the user is working
% exclusively in one language, he will need some kind of switching method.
% Most language installations provide tests for the current language, and
% these would have to be built into the {\tt babelbst.tex} file.
% \subsection{Adding New Languages to the Master File}
% To add a new language to this master file, changes must be made at 6
% places, all of which are marked with the text {\tt NEWLANGUAGE:}. You
% only need to search for these and follow the instructions there, also
% looking at the existing languages as examples.
% Let us suppose the language Newl is to be added with the {\tt docstrip}
% option name {\tt newlang}.
% \begin{enumerate}
% \item
%   Add an entry in the description of the options. This will appear as
%   \begin{quote}
%     \verb!% \item[newlang]      the equivalent Newl words;!
%   \end{quote}
% \item
%   Add the option to the {\tt makebst} language menu. This will be like
%   \begin{quote}
%   \verb!\optdef{x}{newlang}{Newl}{}!
%   \end{quote}
%   where {\tt x} stands for some unique letter within the menu.
% \item
%   Add a headline for the {\tt.bst} file that states right at the start
%   for which language it is intended.
%   \begin{quote}
%   \verb!%<newlang> %                NEWL!
%   \end{quote}
% \item
%   Now for the hard part. Add all the translations for {\tt bbl.and} etc.
%   Follow the models shown. The addition should be something like
%   \begin{quote}\small
% \verb!% The Newl translations !\\
% \verb!%    \begin{macrocode}!\\
% \verb!%<*newlang>!\\
% \verb! % The language selected is NEWL!\\
% \verb!FUNCTION {bbl.and}!\\
% \verb!{ "ee"}!\\
% \verb!. . . . . . . . . . . . . .!\\
% \verb!FUNCTION {bbl.fifth}!\\
% \verb=%<!ord>{ "Frotty" }=\\
% \verb!%<ord>{ "5-y" }!\\
% \verb! !\\
% \verb!FUNCTION {bbl.th}!\\
% \verb!{ "-y" }!\\
% \verb! !\\
% \verb!%</newlang>!\\
% \verb!%    \end{macrocode}!
%   \end{quote}
% \item
%   A similar addition is made for the names of the months.
% \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
%   Finally, 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).
%   This command must then be defined for the source text, by adding its
%   definition to the start of the {\tt.bbl} file. The function {\tt
%   begin.bib} already includes this for the {\tt german} option, which may
%   be added in the same manner for other languages.
% \end{enumerate}
% \subsection{Changing {\tt babelbst.tex} for New Languagues}
% If the above is too complex, then a new language can be added by
% modifying the file {\tt babelbst.tex} and selecting the language {\tt
% babel} for the {\tt.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 Newl, then put the
% English version of {\tt babelbst.tex} into {\tt englbst.tex} and the Newl
% version in {\tt newlbst.tex}. Then {\tt babelbst.tex} could contain:
% \begin{quote}\begin{verbatim}
% \ifcase\language \input{englbst} \or \input{newlbst} 
%   \else \input{newlbst} \fi
% \end{verbatim}
% \end{quote}
% This is of course installation dependent. 
% \subsection{A Compromise Method of Adding a Language}
% A third method is a mix between the above two and requires some hacking
% on the part of the user. 
% \begin{enumerate}
% \item 
%   Make up a file like {\tt babelbst.tex} for the new language, say {\tt
%   newlbst.tex}. 
% \item 
%   Generate a {\tt.bst} file with the {\tt babel} language option.
% \item
%   Go to the line near the end of the {\tt.bst} file and replace
%   \begin{quote}\verb!\input{babelbst.tex}! with
%                \verb!\input{newlbst.tex}!
%   \end{quote}
% \end{enumerate}
% The resulting {\tt.bst} file is valid for one language only (as for
% method \ref{one}), and its name should reflect this.
% \subsection{Extracting Sample {\tt babelbst.tex} Files}
% Language dependent definition files suitable to be used as {\tt
% babelbst.tex}, or to be read in by it, are contained in this master file
% for English, German, and French. Extract them with {\tt docstrip} and the
% options {\tt bblbst,english}, {\tt bblbst,german}, and {\tt
% bblbst,french}.
% \subsection{Problem with Edition Numbers}
% Something to note here is the ordinal numbers for editions. \btx{}
% demands that the field {\tt edition} be given in the database as a word
% `First', `Second', etc., or as `1st', `2nd', etc. This is bad policy
% because it is language dependent. So what I do is to test for the words
% `first' through `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 {\tt 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 (`th' in English)
% added to them. 
% These numbers are only used with the word
% `edition' or its equivalent in other languages, so the translators need
% to provide only the one gender, e.g., feminine for both German and
% French.
% \section{The Options}
% Here I present a list of all the {\tt docstrip} 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 {\tt 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.
% For example, if {\tt a} and {\tt b} are to be mutually exclusive, then
% the three possibilities are:
% \begin{quote}\begin{tabular}{rl}
% neither &  \tt\%<!a\&!b> \\
% {\tt a} only & \tt\%<a> \\
% {\tt b} only & \tt\%<!a\&b>
% \end{tabular}\end{quote}
% so that if both {\tt a} and {\tt b} have been selected, the result is as
% if only {\tt a} had been given. (If one uses {\tt makebst} to produce the
% {\tt docstrip} batch job, then it is impossible to give mutually
% exclusive options.)
% Most mutually exclusive options have the same prefix before the hyphen.

% \section{The Menu Information}\label{sec:menu}
% Here I describe the options and menu information for this particular
% master file {\tt\filename}. To construct a {\tt docstrip} driver file
% to generate a desired {\tt.bst} file, simply process {\tt makebst.tex}
% (or {\tt makebst.doc}) with \TeX, 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 this menu information is nested between {\tt docstrip} guard options
% |%<*options>| \dots\ |%</options>|, and the last command is
% |\endoptions|. The rest of the file is nested between |%<*!options>|
% \dots\ |%</!options>| in order to exclude it if {\tt docstrip} is used to
% extract only the menu information.
% \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}
% Other systems are also supported, such as the Harvard family of
% bibliography styles (with {\tt 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 {\tt astron.sty}) with entries like
% \begin{quote}
% |\bibitem[\protect\astroncite{Daly et al.}{1990}]{key}...|
% \end{quote}
% or the Chicago family (with {\tt chicago.sty}) with entries like
% \begin{quote}
% |\bibitem[\protect\citeautheryear{Daly, Keppler, and|\\
% |      Williams}{Daly et al.}{1990}]{key}...|
% \end{quote}
% or the so-called ``author-date'' group (with {\tt authordate1-4.sty})
% with entries of the form
% \begin{quote}
% |\bibitem[\protect\citename{Daly et al.}1990]{key}...|
% \end{quote}
% Finally, there is the {\tt apalike} format of Oren Patashnik, for use
% with {\tt apalike.sty} that has entries of the form
% \begin{quote}
% |\bibitem[Daly et al., 1990]{key}...|
% \end{quote}
% In addition to numerical or author-year citation styles, there is also a
% {\tt cite} style available in which the label is the same as the cite
% key. This is for listing entire contents of databases with the cite key
% visible. 
% A flag |\ifnumerical| is established because some of the following menu
% features depend on which system is to be used.

%    \end{macrocode}
% \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 the same as the original
% citations. This corresponds to {\tt unsrt.bst}.
% 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).

% \subsection*{Selecting Language}\label{babelmenu}
% Explicit words in the bibliography style, such as `and', `editor', etc.,
% are represented by functions {\tt bbl.and}, {\tt bbl.editor}, and so on.
% By default these functions translate to the normal English text, but
% other languages are also possible. All the definitions of these functions
% are kept together to simplify the addition of further languages, or to
% allow someone to hack the {\tt.bst} file for another language.
%^^A NEWLANGUAGE: add an \optdef here, 
%^^A              say \optdef{x}{newlang}{Name of Language}{}

\optdef{e}{espo}{Esperanto}{}
\getans
%    \end{macrocode}
% \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 {\tt.bib} file, then that is all that can appear in the list. Other
% possibilities are to use initials (even if full names in the {\tt.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.
%    \begin{macrocode}
\mes{^^JAUTHOR NAMES:}
\optdef{*}{}{Full, surname last}{(John Frederick Smith)}
\optdef{i}{nm-init}{Initials + surname}{(J. J. Smith)}
\optdef{r}{nm-rev}{Surname + initials}{(Smith, J. J.)}

\getans
%    \end{macrocode}
% \subsection*{Number of authors}
% Normally the complete list of authors as given in the {\tt.bib} file are
% presented in the reference list. However, some journals prefer to limit
% them to a maximum. If there are more than this maximum number of author
% names, then a minimum number plus `et al.' are listed.
% Because no test for consistency of the numbers is carried out in the
% {\tt.bst} file itself (it might be possible, but I found it too complex),
% this is done here.
%    \begin{macrocode}
\mes{^^JNUMBER OF AUTHORS:}

% \subsection*{Position of date}
% This applies to author-year style only. It makes sense to put the date
% immediately after the author list, since the two items (author and year)
% are the identifiers of the reference. Default position is at the
% end of the references, before any notes. It is also possible to place
% it even after the notes.

% \subsection*{Format of date}
% The year may be enclosed in parentheses, brackets, or preceded by a
% colon. If none of these are selected, the date (month plus year) appears. 
% For author-year, the date always consists only of the year, no month.

\getans
%    \end{macrocode}
% \subsection*{Article title in journal}
% The title of an article in a journal or in a collection (a book, or
% conference proceedings) may appear plain, in italics, within single
% or double quotes. 
% Furthermore, it may have sentence capitalization (first
% word and word following colon) or be capitalized as in the {\tt.bib} file
% entry. That is why it is recommended to capitalize the entry text as it
% should appear when fully capitalized, putting words that are always
% capitalized in braces. Example:
% \begin{quote}
% |TITLE="The Results of the {Giotto} Mission"|
% \end{quote}
% which produces either ``The results of the Giotto mission'' or ``The
% Results of the Giotto Mission'', depending on option.
% Additionally, the article titles may be fully suppressed.
%    \begin{macrocode}

\getans
%    \end{macrocode}
% \subsection*{Journal reference}
% Great diversity of opinion exists as to how a journal reference is to be
% formatted. It consists of a volume, possibly a number, and page limits.
% The number is really only necessary if the page numbers within one volume
% start at 1 for each physical `number'. Since journals are often bound
% together in one volume later, it makes more sense to number the pages
% continuously through the whole volume. However, this is not always so,
% and then the `number' is necessary for the full specification.
% A number of styles for journal specifications are
% \begin{quote}
% 21(2):33--55\\
% {\bf 21}(2):33--55\\
% {\it 21}(2), 33--55
% \end{quote}
% Here both start and stop page numbers have been given; often only the
% start page is wanted.
% Finally, it is possible to decide whether the journal name should be
% separated from the following specifications with a blank or comma.
%    \begin{macrocode}
\mes{^^JJOURNAL VOLUME NUMBER:}

% extra label attached to the year. The year always remains plain.
% It is not possible to select the type of brackets for the year, since
% this is determined by the \LaTeX{} style option that manages the
