listlbls --- Creates a list of all labels used throughout a document

This is a package meant to help a LaTeX-writer to keep track all the defined
labels by typesetting a complete list of labels whereever the author requests
it. Keep in mind, that you might need to have additional LaTeX runs to get the
references right.

This package is based on an answer David Carlisle gave on tex.stackexchange.com
in the thread ``List of all labels with hyperlinks''[1].

% \begin{abstract}
% This is a package meant to help a \LaTeX-writer to keep track all the defined labels by typesetting a complete list of labels whereever the author requests it. Keep in mind, that you might need to have additional \LaTeX\ runs to get the references right.
%
% This package is based on an answer \textsc{David Carlisle}\ gave on \TSE in the thread \href{http://tex.stackexchange.com/questions/147695/list-of-all-labels-with-hyperlinks/147705#147705}{List of all labels with hyperlinks}.

% \end{multicols}
% \section{Installation}\label{sec:install}
% 
% The following explanations are only valid for Linux-like systems with gnu-|make| available.
%
% \subsection{\TeX live}\label{ssec:inst-tl}
%
% This package is bundled in \TeX live, so you can simply (|sudo|) |tlmgr install listlbls| (which should work for windows as well)
%
% \subsection{From Github}\label{ssec:inst-gh}
%
% \begin{enumerate}
%   \item Check out the sourcecode from \href{https://github.com/}{GitHub}:\\
%     |git clone git@github.com:NobbZ/listlbls.git|
%   \item Switch to the source-folder:\\|cd listlbls|
%   \item Checkout the branch/tag you desire: |master| for latest release, |develop| for latest builds (might be broken) or the version number desired.\\
%     |git checkout <branch/tag>|
%   \item Compile the document using |make|:\\
%     |make all|
%   \item You can do either a user-installation or a system-wide installation:
%     \begin{description}
%       \item[user:] |make inst|
%       \item[system:] |make install| (will ask for root!)
%     \end{description}
% \end{enumerate}
%
% \subsection{From CTAN}\label{ssec:inst-ctan}
%
% \begin{enumerate}
%   \item Browse to \url{http://ctan.org/pkg/listlbls}.
%   \item Download the package as zip archive (``Download'' at the bottom of the page).\\
%     |wget http://mirrors.ctan.org/macros/latex/contrib/listlbls.zip|
%   \item Unzip wherever you want. \\
%     |unzip listlbls.zip|
%   \item |cd| into the directory you unzipped to. \\
%     |cd listlbls|
%   \item You can do either a user-installation or a system-wide installation:
%     \begin{description}
%       \item[user:] |make inst|
%       \item[system:] |make install| (will ask for root!)
%     \end{description}
% \end{enumerate}
%
% \section{Usage}\label{sec:usage}
%
% \subsection{Initialization}\label{ssec:use-init}
%
% Just activate the package as usual: |\usepackage|\oarg{options}|{listlbls}|
%
% \DescribeOption{draft} If |draft| is given as option, |\listoflabels| will typeset the list of labels.
%
% \DescribeOption{final} If |final| is given as option, |\listoflabels| will do nothing. Please remember, that |final| is set globally by most documentclasses.
%
% \DescribeOption{totoc} If this is given the List of Labels will appear in a table of contents (unnumbered).
%
% \DescribeOption{notoc} If this is given the List of Labels will \emph{not} appear in a table of contents, but it will still have a headline.
%
% \DescribeOption{numtoc} Typesets a numbered headline, this option also implies |totoc|!
%
% \DescribeOption{nonameref} Even if the package |nameref| if detected, it will not be used.
%
% This document was typeset with |\usepackage[draft,totoc]{listlbls}| also the package |nameref| was loaded.
%
% A locally set option will win against a globally set contrary option!
%
% \subsection{Macros}\label{ssec:use-macros}
%
% Then anywhere in your document, you can use the |\listoflabels|-macro to typeset a list of labels. An example can be seen on page \pageref{special:listoflabels}.
%
% \DescribeMacro{\label} Use |\label| as you are used to it!
%
% \DescribeMacro{\listoflabels} This macro will typeset the list of labels when this module is in draft mode. It will itself register the label ``|special:listoflabels|''.

% \section{Contribution and bugreports}\label{sec:contribute}
%
% If you have feature-requests or bug-reports, please feel free to report them on the \href{https://github.com/NobbZ/listlbls}{project page at GitHub}.
%
% If you want to contribute then follow these steps:
% \begin{enumerate}
%   \item Visit the \href{https://github.com/NobbZ/listlbls}{project page at GitHub},
%   \item forkt it,
%   \item clone it to your local machine,
%   \item create a branch ``|feature/|\meta{feature name}'',
%   \item do your changes,
%   \item push them back to GitHub,
%   \item create a pull request to |develop|,
%   \item and wait for approval.
% \end{enumerate}
% After approval your code will be merged to the |development|-branch and I will generally not accept pull-requests that edit |develop| directly.
