+
+About
+-----
+
+checkcites is a Lua script written for the sole purpose of detecting
+unused or undefined references from both LaTeX auxiliary or
+bibliography files. We use 'unused reference' to refer to the
+reference present the bibliography file -- with the '.bib'
+extension -- but not cited in the '.tex' file. The 'undefined
+reference' is exactly the opposite, that is, the items cited in the
+'.tex' file, but not present in the '.bib' file.
+
+The original idea came from a question posted in the TeX.sx community
+about how to check which bibliography entries were not used. We
+decided to write a script to check references. We opted for Lua,
+since it's a very straightforward language and it has an interpreter
+available on every modern TeX distribution.
+
+Installation
+------------
+
+1. Create a new directory named 'checkcites' inside the 'scripts'
+ directory of your TEXMF tree and copy the 'checkcites.lua' inside
+ the new directory. In TeX Live, the new directory would be:
+
+ texlive/<year>/texmf/scripts/checkcites
+
+2. Rebuild the filename databases with the proper distro tool,
+ e.g, running 'mktexlsr'.
+
+3. Create a symbolic link to the newly created script inside
+ the 'bin' directory of your TeX distro. In TeX Live, the
+ full path is:
+
+ texlive/<year>/bin/<arch>
+
+ For TeX Live:
+
+ Win32: make a copy of 'runscript.exe' inside the very same
+ location (i.e, 'bin/win32') and rename it to
+ 'checkcites.exe'.
+
+ Linux: create a symbolic link (i.e, 'ln -s') inside the 'bin'
+ directory, targeting the script set in #1. Name it
+ 'checkcites' and give it proper execute ('x') permission.
+
+Usage
+-----
+
+The script is pretty simple to use. The only requirement is a recent
+TeX distribution, such as TeX Live. Then run checkcites:
+
+$ checkcites
+
+It will print the script usage. The only required argument is the
+'.aux' file which is generated when you compile your '.tex' file.
+If your main document is named 'foo.tex', you will have a 'foo.aux'
+file too. To run the script on that file, go with:
+
+$ checkcites foo.aux
+
+checkcites allows an additional argument that will tell it how to
+behave. For example
+
+$ checkcites --unused foo.aux
+
+will make the script only look for unused references in your '.bib'
+file. The argument order doesn't matter, you can also run
+
+$ checkcites foo.aux --unused
+
+and get the same behaviour. Similarly, you can use
+
+$ checkcites --undefined foo.aux
+
+to make the script only look for undefined references in your
+'.tex' file. If you want checkcites to look for both unused and
+undefined references, go with
+
+$ checkcites --all foo.aux
+
+If no special argument is provided, --all is set as default.

+\section{Introduction}
+\label{sec:intro}
+
+\checkcites\ is a Lua script written for the sole purpose of detecting
+unused or undefined references from both \LaTeX{} auxiliary or
+bibliography files. We use \emph{unused reference} to refer to the
+reference present the bibliography file --~with the \verb|.bib|
+extension~-- but not cited in the \verb|.tex| file. The
+\emph{undefined reference} is exactly the opposite, that is, the items
+cited in the \texttt{.tex} file, but not present in the \verb|.bib|
+file.
+
+The original idea came from a question posted in the
+\href{http://tex.stackexchange.com}{TeX.sx community} about
+\href{http://tex.stackexchange.com/questions/43276}{how to check which
+bibliography entries were not used}. We decided to write a script to
+check references. We opted for Lua, since it's a very straightforward
+language and it has an interpreter available on every modern \TeX\
+distribution.
+
+\begin{infoblock}{Attention!}
+\checkcites\ is known to run with the most recent \verb|texlua| and
+\verb|lua| interpreters. Unfortunately, the code is incompatible with
+interpreters prior to the Lua 5.1 language specification.
+\end{infoblock}
+
+\section{How the script works}
+\label{sec:howto}
+
+\checkcites\ uses the generated \verb|.aux| file to start the
+analysis. The first step is to extract all citations found, in the
+form of \verb|\citation{a}|. For every \verb|\citation| line found,
+\checkcites\ will extract the citations and add them to a table, even
+for multiple citations separated by commas, like
+\verb|\citation{a,b,c}|. Then the citations table has all duplicate
+values removed --~in other words, the table becomes a set. Let's call
+$A$ the set of citations.
+
+\begin{infoblock}{Attention!}
+If \verb|\citation{*}| is found, the script ends, mainly because all
+citations will be used in this case. We opted for ending the script
+instead of ignoring this step.
+\end{infoblock}
+
+At the same time \checkcites\ also looks for bibliography data, in the
+form of \verb|\bibdata{a}|. Similarly, for every \verb|\bibdata| line
+found, the script will extract the bibliography data and add them to a
+table, even if they are separated by commas, like
+\verb|\bibdata{d,e,f}|. The table has all duplicate values removed.
+
+\begin{infoblock}{Attention!}
+If no \verb|\bibdata| command is found, the script ends. There's
+nothing to do in this case.
+\end{infoblock}
+
+Now, \checkcites\ will extract all entries from the bibliography files
+found in the previous step. For every element in the bibliography data
+table, the script will look for entries like \verb|@BOOK|,
+\verb|@ARTICLE| and so forth --~we actually use pattern matching for
+this~-- and add their identifiers to a table. The script treats all
+\verb|.bib| files as if they were only one. After all files have been
+analyzed and all entries identifiers extracted, the table has all
+duplicate values removed. Let's call $B$ the set of bibliography
+entries.
+
+\begin{infoblock}{Attention!}
+If \checkcites\ cannot find a certain bibliography file --~that is, a
+\verb|.bib| file~-- the script ends. Make sure to put the correct
+name of the bibliography file in your \verb|.tex| file.
+\end{infoblock}
+
+Now we have both sets $A$ and $B$. In order to get all unused
+references in the \verb|.bib| files, we compute the set difference
+\[
+B - A = \{ x : x \in B, x \notin A \}.
+\]
+Similarly, in order to get all undefined references in the \verb|.tex|
+file, we compute the set difference
+\[
+A - B = \{ x : x \in A, x \notin B \}.
+\]
+If there are either unused or undefined references, \checkcites\ will
+print them in a list format. In Section~\ref{sec:usage} there's a more
+complete explanation on how to use the script.
+
+\section{Usage}
+\label{sec:usage}
+
+\checkcites\ is very easy to use. First of all, let's define two files
+that will be used here to explain the script usage. Here's our sample
+bibliography file \verb|example.bib|, with five fictional entries.
+
+\begin{tcblisting}{colframe=DarkTurquoise,coltitle=black,listing only,
+ title=Bibliography file, fonttitle=\bfseries,
+ listing options={columns=fullflexible,basicstyle=\ttfamily}}
+@BOOK{foo:2012a,
+ title = {My Title One},
+ publisher = {My Publisher One},
+ year = {2012},
+ editor = {My Editor One},
+ author = {Author One}
+}
+
+@BOOK{foo:2012b,
+ title = {My Title Two},
+ publisher = {My Publisher Two},
+ year = {2012},
+ editor = {My Editor Two},
+ author = {Author Two}
+}
+
+@BOOK{foo:2012c,
+ title = {My Title Three},
+ publisher = {My Publisher Three},
+ year = {2012},
+ editor = {My Editor Three},
+ author = {Author Three}
+}
+
+@BOOK{foo:2012d,
+ title = {My Title Four},
+ publisher = {My Publisher Four},
+ year = {2012},
+ editor = {My Editor Four},
+ author = {Author Four}
+}
+
+@BOOK{foo:2012e,
+ title = {My Title Five},
+ publisher = {My Publisher Five},
+ year = {2012},
+ editor = {My Editor Five},
+ author = {Author Five}
+}
+\end{tcblisting}
+
+The second file is our main \LaTeX{} document, \verb|document.tex|.
+
+\begin{tcblisting}{colframe=DarkTurquoise,coltitle=black,listing only,
+ title=Main document, fonttitle=\bfseries,
+ listing options={columns=fullflexible,basicstyle=\ttfamily}}
+\documentclass{article}
+
+\begin{document}
+
+Hello world \cite{foo:2012a,foo:2012c}, how are you \cite{foo:2012f},
+and goodbye \cite{foo:2012d,foo:2012a}.
+
+\bibliographystyle{plain}
+\bibliography{example}
+
+\end{document}
+\end{tcblisting}
+
+Open a terminal and run \verb|checkcites|:
+
+\begin{terminal}
+\begin{verbatim}
+$ checkcites
+\end{verbatim}
+\tcblower
+\begin{verbatim}
+checkcites.lua -- a reference checker script (v1.0g)
+Copyright (c) 2012 Enrico Gregorio, Paulo Roberto Massa Cereda
+
+Usage: checkcites.lua [--all | --unused | --undefined] file.aux
+
+--all Lists all unused and undefined references.
+--unused Lists only unused references in your 'bib' file.
+--undefined Lists only undefined references in your 'tex' file.
+
+If no flag is provided, '--all' is set by default.
+Be sure to have all your 'bib' files in the same directory.
+\end{verbatim}
+\end{terminal}
+
+If you don't have \checkcites\ installed with your \TeX\ distribution,
+you can run the standalone script \verb|checkcites.lua| with either
+\verb|texlua| or \verb|lua|. We recommend to use \verb|texlua|, as
+it's shipped with all the modern \TeX\ distributions:
+\begin{terminal}
+\begin{verbatim}
+$ texlua checkcites.lua
+\end{verbatim}
+\end{terminal}
+
+When you run \checkcites\ without providing any argument to it, the
+script usage will be printed, as seen in the previous output. The only
+required argument is the auxiliary file --~with the \verb|.aux|
+extension~-- which is generated when you compile your main \verb|.tex|
+file. For example, if your main document is named \verb|foo.tex|, you
+probably have a \verb|foo.aux| file too. Let's compile our sample
+document \verb|document.tex|:
+\begin{terminal}
+\begin{verbatim}
+$ pdflatex document.tex
+\end{verbatim}
+\end{terminal}
+
+After running \verb|pdflatex| on our \verb|.tex| file, there's now a
+\verb|document.aux| file in our work directory.
+
+\begin{tcblisting}{colframe=DarkTurquoise,coltitle=black,listing only,
+ title=Auxiliary file, fonttitle=\bfseries,
+ listing options={columns=fullflexible,basicstyle=\ttfamily}}
+\relax
+\citation{foo:2012a}
+\citation{foo:2012c}
+\citation{foo:2012f}
+\citation{foo:2012d}
+\citation{foo:2012a}
+\bibstyle{plain}
+\bibdata{example}
+\end{tcblisting}
+
+Now we can run \checkcites\ on the \verb|document.aux| file:
+
+\begin{terminal}
+\begin{verbatim}
+$ checkcites document.aux
+\end{verbatim}
+\tcblower
+\begin{verbatim}
+checkcites.lua -- a reference checker script (v1.0g)
+Copyright (c) 2012 Enrico Gregorio, Paulo Roberto Massa Cereda
+
+I found 4 citation(s).
+Great, there's only one 'bib' file. Let me check it.
+I found 5 reference(s).
+
+Unused reference(s) in your bibliography file(s): 2
+- foo:2012b
+- foo:2012e
+
+Undefined reference(s) in your TeX file: 1
+- foo:2012f
+\end{verbatim}
+\end{terminal}
+
+As we can see in the script output, \checkcites\ analyzed both
+\verb|.aux| and \verb|.bib| files and found two unused references in
+the bibliography file --~\verb|foo:2012b| and \verb|foo:2012e|~-- and
+one undefined reference in the document --~\verb|foo:2012f|.
+
+\checkcites\ allows a command line switch that will tell it how to
+behave. For example,
+
+\begin{terminal}
+\begin{verbatim}
+$ checkcites --unused document.aux
+\end{verbatim}
+\end{terminal}
+
+The \verb|--unused| flag will make the script only look for unused
+references in the \verb|.bib| file. The argument order doesn't matter,
+you can also run
+
+\begin{terminal}
+\begin{verbatim}
+$ checkcites document.aux --unused
+\end{verbatim}
+\end{terminal}
+
+The script will behave the same. Similarly, you can use
+
+\begin{terminal}
+\begin{verbatim}
+$ checkcites --undefined document.aux
+\end{verbatim}
+\end{terminal}
+
+The \verb|--undefined| flag will make the script only look for
+undefined references in the \verb|.tex| file. If you want \checkcites\
+to look for both unused and undefined references, run:
+
+\begin{terminal}
+\begin{verbatim}
+$ checkcites --all document.aux
+\end{verbatim}
+\end{terminal}
+
+If no special argument is provided, the \verb|--all| flag is set as default.
