%^^A** abstract
% \begin{abstract}
%   \package{Achicago} provides a documentation style for \LaTeX{} that aims
%   for compliance with the \manual.  It uses author-date citations (per
%   ch.~16), but bibliography entries contain unabbreviated information (per
%   ch.~15).  Requires accompanying \BibTeX{} bibliography style,
%   \bst{achicago}.
% \end{abstract}
% \tableofcontents
%
% \part{Discussion}
% \AddToCheckSum{10}^^A FIX no idea why I have to do this.
%
% \section{General}
%
% This package is a companion to the \bst{achicago} \BibTeX{} bibliography
% style.  The set of citation commands offered by \package{achicago} is
% unfortunately shared only with an early implementation of a \manual-compliant
% documentation style, \package{achicago} and \bst{achicago}.  FIX: any others?
% In the future, I hope to make \package{achicago} compatible with the most
% common 
% 
% have to commit to using this bibstyle-package combination when you write your
% sources.  This needn't be true, and one day I am going to create a series of
% mappings from other common bibstyles that are conceptually similar, such as
% the \bst{harvard} styles.  The user commands are slightly different, but it
% should be the case that either set of user commands can be the front end for
% either bibstyle.
%
% Here in this documentation you will read about the commands you will use in
% your \LaTeX{} source file to make citations, and what the citations look
% like.  Documentation of the \bst{achicago} bibstyle itself is in the file
% \file{achicago-bst.dvi}.  There you can read about what the References
% section, the actual book list, looks like.  There are also some new fields
% recognized and other information you might want to know that relates to your
% \BibTeX{} bibliography database file (\ext{bib} file).  You may also wish to
% look at the \package{titles} package (also in the \Frankenstein bundle),
% which can be very helpful in typesetting various styles of titles properly,
% even when nested.  The \package{achicago} package already requires the
% \package{titles} package, so those commands are always there if you want to
% use them.
%
% \caveat{This documentation is sparse but should be accurrate.  I will improve
% it in the future.}
%
% \section{Notes on the future of this package and bibstyle}
%
% \manualref{16.25} permits this combination.
%
% In the future I hope to document more closely \manual's principles wrt each
% entry type, the many choices given by \manual.
% 
% Untested and indeed hardly testable nature of the subject, with all its many
% permutations and difficult special bibliographic cases.  Feedback is very
% welcome, especially with citations from  \manual.
%
% FUTURE One thing I realize now is that I've kept the same user interface I
% inherited, which I don't think corresponds with any other popular style.
% Besides refinement, this is the next major step in the future of this
% bibstyle-package.
%
% \section{Pros and cons of this style}
%
% FIX: terminology: reference style, citation style, bibstyle, bibliography style
%
% When you are required to use a certain reference style, your judgment is not
% called for.  In the cases where it is, here are some considerations.
%
% \begin{description}
%   \item[citations are verbose]

%   Sometimes this information is useful to the reader, sometimes not.  If in
%   most citations it is not useful, consider a style with briefer citations.
%   \item[citation style and quality of writing]
%%
%   FIX cite btxdoc Oren Patashnik argues that ``encourages the passive
%   voice and vague writing.''  I'm not sure.  Even if it's true, an author can
%   surely resist this ``encouragement.''  To encourage is not to require.  Do
%   consider how well \emph{you} write using different citation styles.  If the
%   document is already written, realize that if you change the citation style
%   to one different than the author had in mind while writing, you may make
%   reading it more awkward.  Then again, maybe you will improve it.
%   \item[ease of locating references] 
%
%   The entry for (Benson et~al. 1980) will appear any number of entries
%   \emph{after} the entry for (Benson et~al. 1999) when the former was written
%   by Benson, Zymursky, Wheeler, and Flynn and the latter by Benson (i.e., the
%   same Benson), Floyd, Wheeler, and Flynn, since Zymursky compares greater
%   than Floyd.
%
%   This is an issue to consider if you have a large number of entries with the
%   same initial author (or editor) and often with different sets of 3 or more
%   subsequent authors.  This is, in general, very unlikely.
%
%   The entry for (Gr\"uber 1990b) may not follow the entry for (Gr\"uber
%   1990a) immediately.  When (the same) Gr\"uber has authored 
%   Any number of entries may intervene, but their
%   principals will all be exactly Gr\"uber.  Entries will intervene only in
%   the case when Gr\"uber both authored and edited a work in the same year,
%   and authored one a work with a later date.  
% \end{description}
%
% \section{Usage}
%
% Here are the various citing commands, and examples of the citations they produce.
%
% \todo{What about the situation when you end a sentence with something ending
% with ``et~al.''---in this case you don't want to reproduce the period.}
%
% Distinct examples are \typeset{distinguished this way}.
%
% \begin{tabular}{*{3}{p{.33\textwidth}}}
%  \cs\cite\marg{key}
%    & parenthesized list of up to 3 principals or one ``et~al.'' plus a year label
%    & \typeset{(Brown 1978)} \typeset{(Jarke, Turner, and Stohl 1985)} \\

% \end{tabular}
% \footnotetext{This command should only be used for one key.}
% \todo{Should I use a warning in case more than one key is given to a command
% that shouldn't have them?}
%
%   \subsection{Short citation labels}
%
% Previous versions of \package{achicago} offered a parallel set of citation
% commands with the prefix |short| that created citations with abbreviated
% labels (\cs\shortcite, \cs\shortciteNP, \cs\shortciteA, \cs\shortciteANP,
% \cs\shortciteN).  \package{Achicago} now offers only one kind of label, which
% is abbreviated according to principles in the \manual as much as possible.
% For backwards compatibility, the |short| citation commands still function,
% but they are identical to their non-|short|, and will produce a warning that
% this syntax is deprecated.  Do not use the |short| commands in new documents.
%
% \section{Some technical notes}
%
% \todo{See \manualref{16.14} for issues to do with multiple citations.}
%
% \section{History}
% 
% I wrote this package incorporating \file{chicago\{,a\}.bst} and
% file{chicago.sty} (v4, 92/8).  By now I've almost totally rewritten it.  It
% was a great mess because it had been based on \file{newapa.bst} which had
% been based on several other bibstyles, and each author had really just hacked
% up what was there in the previous bibstyle apparently without fully
% understanding it.  Now, of course, it is a shining example of clarity and
% efficiency.
