%
% Allow multiple bibliographies in a LaTeX document, including items
% \cite'd in more than one bibliography. Despite the name "chapterbib",
% the BIBLIOGRAPHIES ARE FOR EACH INCLUDED FILE, not necessarily for each
% chapter. The main point is to allow you to use BibTeX: Each included
% file should have its own \bibliography command, and you should run
% BibTeX on each included file separately rather than on the root file.
%
% There are also the commands \begin{cbunit}, \end{cbunit}, and \cbinput
% to allow multiple bibliographies without using \include (see item 4).
% There are two added hooks, \citeform and \citepunct, to customise the
% formatting of each entry in a citation list.
%
% Usage, Restrictions, and Options
% ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
%
% 1. Normal usage: Put a \bibliography command in each \include'd file;
% run LaTeX; run BibTeX on each included file; run LaTeX; run LaTeX.
%
% 2. If you get errors like "! LaTeX Error: Command \xxx already defined."
% then bibtex is foolishly putting "\newcommand" in each bbl file. The
% fix is to put the \bibliography command in braces: {\bibliography{x}}.
%
% 3. The \bibliography and \bibliographystyle commands are not normally used
% in the root file, only in files that have been \include'd. To have a
% whole-document bibliography plus chapter-bibs, see item 5; for an
% independent partial bib in the root file, go on to item 4.
%
% 4. If you want a completely independent bibliography in the root file,
% you must provide your own bibliography there using the thebibliography
% environment. I don't suppose this will appeal to BibTeX users!
%
% 5. To have a bibliography for the whole document, plus individual bibs,
% put \bibliography commands in the included chapters plus in the root
% file; use \usepackage[rootbib]{chapterbib}; run LaTeX; run BibTeX
% on the root file; change to \usepackage{chapterbib}; run LaTeX; run
% BibTeX on each included file; run LaTeX; run LaTeX.
% An `overall' bibliography only makes sense for various `named'
% bibliography styles; a style with numbering will give separate and
% unrelated numbers in each bibliography.
%
% 6. If you can't use \include because a new section must start below the
% preceding bibliography on the same page [odd format!], then you can
% use \begin{cbunit}...\end{cbunit} or \cbinput, with a {thebibliography}
% environment in each unit or input file. To use BibTeX: input separate
% files using \cbinput; at first use the package or global option [draft],
% run LaTeX on the document, then BibTeX on each file that was \cbinput;
% finally, remove the [draft] option and run LaTeX again (maybe twice to
% get page references right). The [draft] option only affects the treatment
% of \cbinput, not \include or \begin{cbunit}.
% With old LaTeX, do the preliminary run using \include commands, and
% change these to \cbinput for the final run(s).
%
% 7. Your preferred citation style (xxx.sty) may not work with chapterbib at
% first, but it is easy to make it compatible: In `xxx.sty' change every
% "b@\@citeb" to "b@\@citeb\@extra@b@citeb", and insert the line
% \@ifundefined{@extra@b@citeb}{\def\@extra@b@citeb{}}{}
% somewhere (but not as a comment or as part of another definition!).
% If the style file also redefines \bibcite then you should change that
% definition, replacing "b@#1" with "b@#1\@extra@binfo", and insert
% \gdef\@extra@binfo{}
% somewhere in the file.
%
% 8. The report and book document classes usually treat the bibliography as
% an unnumbered chapter (\chapter*), which is not so good for bibliographies
% IN a chapter. You can specify
% \usepackage[sectionbib]{chapterbib}
% and your bibliographies will be treated as sections (\section*) with an
% entry in the table of contents and the page-header. A bibliography in
% the root file remains as a \chapter*. The [sectionbib] option modifies
% the existing thebibliography environment, so the other formatting in the
% bibliography should remain unchanged. On the other hand, if you already
% have a non-standard bibliography defined, or if you want them numbered,
% it may be easier to redefine \thebibliography directly, without any
% trickery.
% For more control, or in old LaTeX2.09, you can use the \sectionbib
% command directly in the document preamble. It takes two parameters:
% the sectioning command, and the name of the sectioning level. For
% instance, the [sectionbib] option does \sectionbib{\section*}{section}.
%
% \citeform and \citepunct:
% ~~~~~~~~~~~~~~~~~~~~~~~~~
% Normally, the citations are formatted as given, but you can define \citeform
% (with one parameter) to reformat every citation. Some possibilities:
% \renewcommand\citeform[1]{\romannumeral 0#1}% roman numerals: [iv,x]
% \renewcommand\citeform[1]{(#1)} % parentheses: [(3),(4),(7)]
% \renewcommand\citeform[1]{\thechapter.#1} % number by chapter: [3.9,3.10]
% If you change \citeform, you should define \@biblabel to match.
% \citepunct gives the punctuation (comma-penalty-space) between items.
%
% -----------------Implementation notes---------------
%
% LaTeX normally uses command names in the form \b@TAG to associate a mnemonic
% TAG with the citation name or number. Chapterbib changes this to a command
% like \b@TAG@-nn where nn is a number identifying which included file is in
% effect.
%
% Tags indicating the citations and/or the input files:
% ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
% \c@inputfile = counter counting included files
% \the@ipfilectr = (empty) when typesetting from the root file,
% = @-\the\c@inputfile when typesetting from an included file
% \@extra@b@citeb = \the@ipfilectr (just an alias)
% \@extra@binfo = the value of \@extra@b@citeb as saved in .aux files
%
% \b@FOO:
% ~~~~~~~
% In the root file, the citation number (or name) is given by \b@FOO
% just like regular LaTeX, but in an \include'd file it is given by
% \b@FOO@-number. Any definition of \cite (\@citex) should refer
% to this using \csname b@\@citeb\@extra@b@citeb \endcsname.
%
% \include \cbinput and \cbunit:
% ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
% Redefine the \include macro so that when a file is \include'd...
% Increment the file number, (globally) update \the@ipfilectr to be
% @-number, and write \gdef\@extra@binfo{@-number} in the (main) .aux
% file, and do regular \include. When the \include'd file is finished,
% write \gdef\@extra@binfo{} in the (main) .aux file. Globally reset
% \the@ipfilectr to {}. Provide similar \cbunit and \cbinput.
%
% \cite:
% ~~~~~~
% Redefine \cite (\@citex actually) and \bibcite to use the file number
% tag along with the specified tag. \@citex also uses \citeform as a hook
% to reformat each individual citation.
% Only do the redefinitions if no citation style that supports chapterbib
% has been loaded--as indicated by existence of filename tags.
%
% \citepunct and \citeform:
% ~~~~~~~~~~~~~~~~~~~~~~~~~
% These customization hooks are present in cite.sty; others (\citemid,
% \citeleft, \citeright) are not defined here because \@cite is not redefined.
% We redefine \@testdef so that it properly checks whether the
% \cite labels have changed.
% Handle package options and redefining thebibliography. [sectionbib]
% converts "\chapter*{...}" to "\section*{\bibname\markright{\bibname}%
% \addcontentsline{toc}{section}{\bibname}}"

% ~~~~~~~ Donald Arseneau <asnd@reg.triumf.ca> March 1993 - Sept 1996
%
% Changes with ver 1.6: change the \sectionbib command to take arguments.
% Changes with ver 1.5: rootbib option; item 2 in instructions.
% Changes with ver 1.4: sectionbib and draft options
% Changes with ver 1.3: rewrite:
% The filename tag is defined in each .aux file by \include, not as an
% extra parameter to \bibcite. \@bibitem & \@lbibitem are left alone. Add
% \citeform and \citepunct. Add \cbunit and \cbinput for use without \include.
