% \section{Introduction}
%
% Software has bugs and \LaTeX{} unfortunately is no exception. If
% somebody encounters a bug then it helps if that bug gets reported to
% the right people so that the bug can be resolved (or a workaround
% documented or whatever is most appropriate). The problem is to know
% to whom to report the bug.
%
% The \LaTeX{} Project Team maintains a bug database for its own code
% base (which consists of the \LaTeX{} kernel and some packages that
% have been written by people in the \LaTeX{} Project
% Team). However, the \LaTeX{} universe consists of several thousand
% contributed packages maintained by individuals all over the
% world. And if a bug happens in one of those packages it doesn't help
% anybody if it is dumped at the \LaTeX{} Project's doorstep.
%
% For one, we can't actually change other people's code even if we are able to
% identify the issue. Furthermore we are only a few people and simply
% do not have the bandwidth to analyse bugs in other people's work.
%
% We have therefore written this little package called
% \texttt{latexbug} that should help in identifying the rightful
% addressee for a bug report. We ask that it will be loaded in any
% test file that is intended to be sent to the \LaTeX{} bug database
% as part of a bug report.
%
% The package will determine if the test file is in a suitable state
% to be sent to us or if it should be modified first or if it should be
% sent to somebody
% else because the bug is (likely) to be in code not maintained by the
% \LaTeX{} Project Team.
%
% Bug reports sent to the \LaTeX{} bug database
% without that prior verification are likely to
% get closed without being looked at at our end in the future.
%
%
%
% \section{The user interface}
%
% The user interface is simple: the package has no option and doesn't
% define any new commands to be used. All that is required is that the
% package is loaded as the very first step in the test file that shows
% the bug --- in other words before the \verb=\documentclass=.
% For that reason it
% must be loaded using \verb=\RequirePackage= instead of the usual
% \verb=\usepackage= that is used in the preamble of a document.
%
% Thus, a bug report test files should look like this:
% \begin{verbatim}
% \RequirePackage{latexbug}       % <- required first line
%                                 %    followed by:
% \documentclass{article}         % or some other class
%                                 %    followed by:
%   ...                           % <- code showing the bug ...
% \end{document}
% \end{verbatim}
%
% If the test file runs through (showing the bug) without any
% complains for \texttt{latexbug} then the test file is ready to be
% sent to the \LaTeX{} bug database at
% \begin{quote}
%   \texttt{https://www.latex-project.org/bugs/}
% \end{quote}
% If \texttt{latexbug} does generate an error, however, then this
% error needs to be addressed first and the depending on the
% resolution the bug report may has to be sent to somebody else.
%
% An error is generated if the test file makes use of third-party code
% that is not maintained by the \LaTeX{} Project Team. For example, if
% the file would load \texttt{geometry}, \texttt{footmisc} and
% \texttt{hyperref} you
% would see the following:
% \begin{verbatim}
% Package latexbug Error: Third-party file(s)
% (latexbug)                
% (latexbug)                This test file uses third-party file(s)
% (latexbug)                
% (latexbug)                ==============
% (latexbug)                geometry.sty  ->  Hideo Umeki 
% (latexbug)                    <latexgeometry [at] gmail [dot] com>
% (latexbug)                footmisc.sty
% (latexbug)                hyperref.sty  ->  Heiko Oberdiek 
% (latexbug)                    https://github.com/ho-tex/hyperref/issues
% (latexbug)                ==============
% (latexbug)                
% \end{verbatim}
% It then continues with advice to remove such third-party code from the
% test file. If that is not possible, because the bug goes away if a
% package is removed, then the problem is (most likely) with this
% package and the bug report should be sent to the maintainer of that
% package and not to the \LaTeX{} bug database.
% \begin{verbatim}
% (latexbug)                So you should contact the authors
% (latexbug)                of these files, not the LaTeX Team!
% (latexbug)                (Or remove the packages that load
% (latexbug)                them, if they are not necessary to
% (latexbug)                exhibit the problem).
% \end{verbatim}
% To make life somewhat easier \texttt{latexbug} will tell you the
% name of the maintainer (if we know it and have added it in) and if
% possible also the canonical bug address for the package (like in the
% case of \texttt{geometry} and  \texttt{hyperref}).
% If we don't have that information, you
% need to find it out for yourself by looking at the package
% documentation.
%
% There may be cases where third-party code is essential to exhibit
% a bug in core \LaTeX{} code maintained by the the \LaTeX{} Team. The
% error text therefore finishes off with the following sentence:
% \begin{verbatim}
% (latexbug)                If you think the bug is in core LaTeX
% (latexbug)                (as maintained by the LaTeX Team) but
% (latexbug)                these files are needed to demonstrate
% (latexbug)                the problem, please continue and mention
% (latexbug)                this explicitly in your bug report.
% \end{verbatim}
% Please explain your reasoning why you think this is the case in
% detail as part of the bug report.

% \subsection{A note on the database content in the package}
%

% When a document is run through \LaTeX{} it will load a number of
% files and bug reports that are to be sent to the \LaTeX{} Team should only
% load files that we maintain and not third-party packages.

% The database, if you want to call that, inside \texttt{latexbug} is
% simply comma separated a key value list consisting of file names
% \texttt{=} maintainer info. Most of the time the maintainer info is
% \texttt{us} or \texttt{us*} (meaning we maintain it, so the file is
% fine) or \texttt{ignore} (meaning we do not maintain it, but it is a
% file that is likely to appear for one or the other reason and we
% should accept such a bug report nontheless).
%
% Any file loaded in the bug report not listed will show up in the
% error listing flagged as ``third-party'' code that should be removed
% as explained above.
%

% For a small number of popular third-party packages we have collected
% the name of the external maintainer and if available to us some
% extra info so that it is easier to send to the rightful addressee if
% you encounter a bug in such a third-party package. But to keep this
% manageable this is only done for a very small number of the 5000+
% packages out there (though we might add one or the other over time).

% It is however not impossible that we missed one or the other file
% that should have been listed as ``maintained by us'' but isn't and
% thus incorrectly generates an error. If you run into that problem or
% notice an omission of that sort, please send us a bug report or open
% an issue at the GitHub source of the package which is located at:
% \begin{quote}
%   \texttt{https://github.com/latex3/latexbug/}

% \section{The documentation driver file}
%
% The next bit of code contains the documentation driver file for
% \TeX{}, i.e., the file that will produce the documentation you are
% currently reading. It will be extracted from this file by the
% \texttt{docstrip} program.
%    \begin{macrocode}
%<*driver>
\RequirePackage{latexbug}
\documentclass{ltxdoc}
\GetFileInfo{latexbug.sty}
%\usepackage{geometry,footmisc,hyperref}  % uncomment for latexbug error
%\usepackage{xparse}                      % uncomment for latexbug error
\EnableCrossrefs
%\DisableCrossrefs    % Say \DisableCrossrefs if index is ready

%\OnlyDescription     % Comment out for implementation details
\begin{document}
   \DocInput{latexbug.dtx}
\end{document}
%</driver>
%    \end{macrocode}
%
% \section{The implementation}
%
%    \begin{macrocode}
%<*package>
\NeedsTeXFormat{LaTeX2e}
\ProvidesPackage{latexbug}[2017/06/10 v1.0a Bug-classification]
%    \end{macrocode}
%
% \begin{macro}{\latexbug@empty}
% \begin{macro}{\latexbug@us}
% \begin{macro}{\latexbug@ustar}
% \begin{macro}{\latexbug@ignore}
%   Fixed text used in checking what actions to take with different files.
%    \begin{macrocode}
\def\latexbug@empty{}
\def\latexbug@us{us}
\def\latexbug@usstar{us*}
\def\latexbug@ignore{ignore}
%    \end{macrocode}
% \end{macro}
% \end{macro}
% \end{macro}
% \end{macro}
%
% \begin{macro}{\Contact}
%   A very simple piece of markup, really.
%    \begin{macrocode}
\def\Contact{\MessageBreak \@spaces}
%    \end{macrocode}
% \end{macro}
%
% The database of packages is set up in a group so we can throw away the
% loop command.
%    \begin{macrocode}
\begingroup
%    \end{macrocode}
%
% \begin{macro}{\latexbug@loop}
%   A simple loop set up which reads a known format for the file-to-maintainer
%   mapping. The trailing space is important (stripping it is not really worth
%   it for this very limited use case).
%    \begin{macrocode}
\long\def\latexbug@loop #1 = #2 , {% spaces matter
  \global\@namedef{latexbug@@#1}{#2}%
  \ifx\latexbug@empty#1\else\expandafter\latexbug@loop\fi}
%    \end{macrocode}
% \end{macro}
%
% A simple database of files. The value \texttt{us} means we accept
% bugs for it. We also take bug reports for \texttt{us*} entries, but
% they need to go to GitHub so are handled separately (and only show up
% if there doesn't seem to be anything else to pick up). A value of
% \texttt{ignore} means that its not our code, but we understand that it may
% show up in legitimate test files and should therefore not trigger an error.
%
% Any file not in there will trigger an error if loaded and any file
% in there with some other value than \texttt{us} or \texttt{ignore}
% will also trigger an error displaying the value (which hopefully is
% the maintainers name). (Handling for \texttt{us*} means these files may
% not show up, depending on the nature of the use case.)
%
% \begin{quote} \itshape
%   The database format is somewhat fragile: one needs to have a space on both sides
%   of the equal sign (or one gets a nasty low-level error) and names can't have
%   no-ascii characters in them, so they end up crippled (sorry for that).
