% This package implements a single command
% {\ttfamily{}\textbackslash{}euflag} which reproduces the official flag
% of the European Union\phantomsection\label{EU}\marginpar{\small\HandRight} (\textsc{eu})\index{European Union|see{EU}}\index{EU|textbf} using the
% built-in \texttt{picture} environment (no need for
% TikZ).\par
% The flag is reproduced at 1em high based on the current
% font size, so it can be scaled arbitrarily by changing the
% font size locally (see examples in the table \vpageref{examples}). An option allows for the flag baseline
% to be aligned on the bottom star.\par

% \section{Background}
% This package provides a command {\ttfamily{}\textbackslash{}euflag}
% for reproducing the flag of the European Union. It follows
% exactly the official specification \parencite{emblem}. The EU’s web site says:\par
% \begin{quotation}\small\sffamily\parindent0pt
%   \parskip.5\baselineskip
%   \color{DarkBlue}\noindent
% The European flag symbolises both the European Union
%   and, more broadly, the identity and unity of Europe.\par
% \textbf{It features a circle of 12 gold
%     stars on a blue background. They stand for the ideals of
%     unity, solidarity and harmony among the peoples of
%     Europe.}\par
% The number of stars has nothing to do with the number of
%   member countries, though the circle is a symbol of
%   unity.\par
% \subsubsection*{History of the European flag}
% The history of the flag goes back to 1955. The Council
%   of Europe — which defends human rights and promotes European
%   culture — chose the present design for its own use. In the
%   years that followed, it encouraged the emerging European
%   institutions to adopt the same flag.\par
% In 1983, the European Parliament decided that the
%   Communities’ flag should be that used by the Council of
%   Europe. In 1985, it was adopted by all EU leaders as the
%   official emblem of the European Communities, later to become
%   the European Union. In addition, all European institutions
%   now have their own emblems.\par
% \hfill\begingroup
%   \scriptsize\color{Black}\url{https://europa.eu/european-union/about-eu/symbols/flag_en}\parfillskip=0pt\par\endgroup
% \end{quotation}
% The {\ttfamily{}\textbackslash{}euflag} command provides a simple
% way to use the flag in any \LaTeX{} document. Details of
% construction and spacing are taken from the official
% specification in the \href{http://publications.europa.eu/code/en/en-5000100.htm}{Graphics 
%   guide to the European emblem}\thinspace.\par
% Since the publication of v0.4 of this package in February
% 2019, Claudio Beccari
% has investigated ways to produce the flag using only \LaTeX{}'s
% drawing facilities and the \textsf{xfp} package. He
% has written a very comprehensive paper about this in
% \emph{\citefield{beccari2019}{journaltitle}}, the journal of the
% Gruppo Utilizzatori
%   Italiani di \TeX{}\phantomsection\label{GUIT}\marginpar{\small\HandRight} (\guit)\index{Gruppo Utilizzatori Italiani di \TeX{}|see{GUIT}}\index{GUIT|textbf}, explaining how he did it
% \parencite{beccari2019}.\par
% More recently Wilhelm Haager has produced the
% \textsf{worldflags} package, which reproduces all the
% world's flags — including the flag of the European Union —
% using the graphics language TikZ \parencite{wflags}.\par
% For an extensive discussion of the flag and its precursors
% and derivatives, see the Wikipedia entry for \emph{\citefield{euroflag}{booktitle}} \parencite{euroflag}.\par
% \clearpage
% \section{Usage}\label{usage}
% The flag is reproduced at 1em high, with the bottom edge
% at the current baseline like this:
% \euflag\  using the
% {\ttfamily{}\textbackslash{}euflag} command. 
% The \textbf{\texttt{baseline}} package option or an optional
% length argument to the {\ttfamily{}\textbackslash{}euflag} command can
% be used to change this (see below).\par
% The font size of the enclosing environment can be changed
% to make the flag appear at any size. In the examples below,
% the code and the flags are in {\ttfamily{}m}-type
% cells (middle-vertical-align, using the
% \textsf{array} package), so their apparent baselines
% differ.\par

% We now use the {\ttfamily{}\textbackslash{}bigstar} command from the
%   \textsf{amssymb} package (earlier versions used
%   the {\ttfamily{}\textbackslash{}FiveStar} command from the
% \textsf{bbding} package, but that did not reliably
% scale beyond about 100pt).\par
% \begin{CPKmacro}{\eustar}\label{macro--eustar}
% It needs to scale, so we implement it as a command
%     using {\ttfamily{}\textbackslash{}scalebox}.\par
%    \begin{macrocode}
\newcommand{\eustar}{\scalebox{0.1}{\ensuremath{\bigstar}}}
%    \end{macrocode}
% This is the only slightly uncertain part of the
%     implementation: the specification calls for the star to be
%     \nicefrac1{18} of the height of the flag, but \LaTeX{} only has
%     access to the bounding-box of the glyph. The value of 0.1
%     given here is therefore experimental and subject to change
%     in future in the light of feedback.\par
% \end{CPKmacro}
% The command itself is a blue {\ttfamily{}\textbackslash{}colorbox}
%   containing the stars set at the clock-points of a circle in
%   a \LaTeX{} \texttt{picture} environment.\par
% \begin{CPKmacro}{\makestars}\label{macro--makestars}
% Separate the making of the ring of stars from the flag
%     itself so that the ring of stars can be used
%     separately.\par
% For the \texttt{picture} environment, set the
%     unit to 1em and then divide it by 18. This enables us
%     conveniently to use six units for the axes behind the circle
%     of stars, because the specification says it must have a
%     radius of \nicefrac13 of the height (ie \nicefrac6{18}). The
%     positioning argument was found by trial and error.\par
%    \begin{macrocode}
\newcommand{\makestars}{%

% \item \label{item-currmaint}If you are the Current Maintainer of the Work, you may,
%   without restriction, modify the Work, thus creating a
%   Derived Work.  You may also distribute the Derived Work
%   without restriction, including Compiled Works generated from
%   the Derived Work.  Derived Works distributed in this manner
%   by the Current Maintainer are considered to be updated
%   versions of the Work.\par
% \item If you are not the Current Maintainer of the Work, you
%   may modify your copy of the Work, thus creating a Derived
%   Work based on the Work, and compile this Derived Work, thus
%   creating a Compiled Work based on the Derived Work.\par
% \item \label{item-conditions}If you are not the Current Maintainer of the Work, you
%   may distribute a Derived Work provided the following
%   conditions are met for every component of the Work unless
%   that component clearly states in the copyright notice that
%   it is exempt from that condition.  Only the Current
%   Maintainer is allowed to add such statements of exemption to
%   a component of the Work.\par
% \begin{enumerate}
% \item If a component of this Derived Work can be a direct
%       replacement for a component of the Work when that
%       component is used with the Base Interpreter, then,
%       wherever this component of the Work identifies itself to
%       the user when used interactively with that Base
%       Interpreter, the replacement component of this Derived
%       Work clearly and unambiguously identifies itself as a
%       modified version of this component to the user when used
%       interactively with that Base Interpreter.\par
% \item Every component of the Derived Work contains
%       prominent notices detailing the nature of the changes to
%       that component, or a prominent reference to another file
%       that is distributed as part of the Derived Work and that
%       contains a complete and accurate log of the
%       changes.\par
% \item No information in the Derived Work implies that any
%       persons, including (but not limited to) the authors of
%       the original version of the Work, provide any support,
%       including (but not limited to) the reporting and
%       handling of errors, to recipients of the Derived Work
%       unless those persons have stated explicitly that they do
%       provide such support for the Derived Work.\par
% \item You distribute at least one of the following with
%       the Derived Work:\par
% \begin{enumerate}
% \item A complete, unmodified copy of the Work; if your
%   distribution of a modified component is made by
%   offering access to copy the modified component from
%   a designated place, then offering equivalent access
%   to copy the Work from the same or some similar place
%   meets this condition, even though third parties are
%   not compelled to copy the Work along with the
%   modified component;\par
% \item Information that is sufficient to obtain a
%   complete, unmodified copy of the Work.\par
% \end{enumerate}
% \end{enumerate}
% \item If you are not the Current Maintainer of the Work, you
%   may distribute a Compiled Work generated from a Derived
%   Work, as long as the Derived Work is distributed to all
%   recipients of the Compiled Work, and as long as the
%   conditions of Clause~\vref{item-conditions}, above, are met
%   with regard to the Derived Work.\par
% \item The conditions above are not intended to prohibit, and
%   hence do not apply to, the modification, by any method, of
%   any component so that it becomes identical to an updated
%   version of that component of the Work as it is distributed
%   by the Current Maintainer under Clause~\vref{item-currmaint}, above.\par
% \item Distribution of the Work or any Derived Work in an
%   alternative format, where the Work or that Derived Work (in
%   whole or in part) is then produced by applying some process
%   to that format, does not relax or nullify any sections of
%   this license as they pertain to the results of applying that
%   process.\par
% \item % \begin{enumerate}
% \item A Derived Work may be distributed under a different
%       license provided that license itself honors the
%       conditions listed in Clause~\vref{item-conditions} above, in
%       regard to the Work, though it does not have to honor the
%       rest of the conditions in this license.\par
% \item If a Derived Work is distributed under a different
%       license, that Derived Work must provide sufficient
%       documentation as part of itself to allow each recipient
%       of that Derived Work to honor the restrictions in
%       Clause~\vref{item-conditions} above, concerning
%       changes from the Work.\par
% \end{enumerate}
% \item This license places no restrictions on works that are
%   unrelated to the Work, nor does this license place any
%   restrictions on aggregating such works with the Work by any
%   means.\par
% \item Nothing in this license is intended to, or may be used
%   to, prevent complete compliance by all parties with all
%   applicable laws.\par
% \end{enumerate}
% \subsection{No Warranty}\label{Warranty}
% There is no warranty for the Work.  Except when otherwise
%       stated in writing, the Copyright Holder provides the Work
%       `as is', without warranty of any kind, either
%       expressed or implied, including, but not limited to, the implied
%       warranties of merchantability and fitness for a particular
%       purpose.  The entire risk as to the quality and performance of
%       the Work is with you.  Should the Work prove defective, you
%       assume the cost of all necessary servicing, repair, or
%       correction.\par
% In no event unless required by applicable law or agreed to
%       in writing will The Copyright Holder, or any author named in the
%       components of the Work, or any other party who may distribute
%       and/or modify the Work as permitted above, be liable to you for
%       damages, including any general, special, incidental or
%       consequential damages arising out of any use of the Work or out
%       of inability to use the Work (including, but not limited to,
%       loss of data, data being rendered inaccurate, or losses
%       sustained by anyone as a result of any failure of the Work to
%       operate with any other programs), even if the Copyright Holder
%       or said author or said other party has been advised of the
%       possibility of such damages.\par
% \subsection{Maintenance of The Work}\label{Maintenance}
% The Work has the status `author-maintained'
%       if the Copyright Holder explicitly and prominently states near
%       the primary copyright notice in the Work that the Work can only
%       be maintained by the Copyright Holder or simply that it is
%       `author-maintained'.\par
% The Work has the status `maintained' if there
%       is a Current Maintainer who has indicated in the Work that they
%       are willing to receive error reports for the Work (for example,
%       by supplying a valid e-mail address). It is not required for the
%       Current Maintainer to acknowledge or act upon these error
%       reports.\par
% The Work changes from status `maintained' to
%       `unmaintained' if there is no Current Maintainer,
%       or the person stated to be Current Maintainer of the work cannot
%       be reached through the indicated means of communication for a
%       period of six months, and there are no other significant signs
%       of active maintenance.\par
% You can become the Current Maintainer of the Work by
%       agreement with any existing Current Maintainer to take over this
%       role.\par
% If the Work is unmaintained, you can become the Current
%       Maintainer of the Work through the following steps:\par
% \begin{enumerate}
% \item Make a reasonable attempt to trace the Current
%   Maintainer (and the Copyright Holder, if the two differ)
%   through the means of an Internet or similar search.\par
% \item If this search is successful, then enquire whether the
%   Work is still maintained.\par
% \begin{enumerate}
% \item If it is being maintained, then ask the Current
%       Maintainer to update their communication data within one
%       month.\par
% \item \label{item-intention}If the search is unsuccessful or no action to resume
%       active maintenance is taken by the Current Maintainer,
%       then announce within the pertinent community your
%       intention to take over maintenance.  (If the Work is a
%       \LaTeX{} work, this could be done, for example, by
%       posting to \url{news:comp.text.tex}.).
% \end{enumerate}
% \item % \begin{enumerate}
% \item If the Current Maintainer is reachable and agrees to
%       pass maintenance of the Work to you, then this takes
%       effect immediately upon announcement.\par
% \item \label{item-announce}If the Current Maintainer is not reachable and the
%       Copyright Holder agrees that maintenance of the Work be
%       passed to you, then this takes effect immediately upon
%       announcement.\par
% \end{enumerate}
% \item \label{item-change}If you make an `intention announcement'
%   as described in~\vref{item-intention} above and after three
%   months your intention is challenged neither by the Current
%   Maintainer nor by the Copyright Holder nor by other people,
%   then you may arrange for the Work to be changed so as to
%   name you as the (new) Current Maintainer.\par
% \item If the previously unreachable Current Maintainer becomes
%   reachable once more within three months of a change
%   completed under the terms of~\vref{item-announce}
%   or~\vref{item-change}, then that
%   Current
%   Maintainer must become or remain the Current Maintainer upon
%   request provided they then update their communication data
%   within one month.\par
% \end{enumerate}
% A change in the Current Maintainer does not, of itself,
%       alter the fact that the Work is distributed under the
%       \textsc{lppl} license.\par
% If you become the Current Maintainer of the Work, you should
%       immediately provide, within the Work, a prominent and
%       unambiguous statement of your status as Current Maintainer.  You
%       should also announce your new status to the same pertinent
%       community as in~\vref{item-intention}
%       above.\par
% \subsection{Whether and How to Distribute Works under This
%       License}\label{Distribute}
% This section contains important instructions, examples, and
%       recommendations for authors who are considering distributing
%       their works under this license.  These authors are addressed as
%       `you' in this section.\par
% \subsubsection{Choosing This License or Another License}\label{Choosing}
% If for any part of your work you want or need to use
% \emph{distribution} conditions that differ
% significantly from those in this license, then do not refer to
% this license anywhere in your work but, instead, distribute
% your work under a different license. You may use the text of
% this license as a model for your own license, but your license
% should not refer to the \textsc{lppl} or otherwise
% give the impression that your work is distributed under the
% \textsc{lppl}.\par
% The document {\ttfamily{}modguide.tex} in the base \LaTeX{}
% distribution explains the motivation behind the conditions of
% this license.  It explains, for example, why distributing
% \LaTeX{} under the \textsc{gnu} General Public
% License (\textsc{gpl}) was considered inappropriate.
% Even if your work is unrelated to \LaTeX{}, the discussion in
% {\ttfamily{}modguide.tex} may still be
% relevant, and authors intending to distribute their works
% under any license are encouraged to read it.\par
% \subsubsection{A Recommendation on Modification Without
% Distribution}\label{WithoutDistribution}
% It is wise never to modify a component of the Work, even
% for your own personal use, without also meeting the above
% conditions for distributing the modified component.  While you
% might intend that such modifications will never be
% distributed, often this will happen by accident~--- you may
% forget that you have modified that component; or it may not
% occur to you when allowing others to access the modified
% version that you are thus distributing it and violating the
% conditions of this license in ways that could have legal
% implications and, worse, cause problems for the community. It
% is therefore usually in your best interest to keep your copy
% of the Work identical with the public one.  Many works provide
% ways to control the behavior of that work without altering any
% of its licensed components.\par
% \subsubsection{How to Use This License}\label{HowTo}
% To use this license, place in each of the components of
% your work both an explicit copyright notice including your
% name and the year the work was authored and/or last
% substantially modified.  Include also a statement that the
% distribution and/or modification of that component is
% constrained by the conditions in this license.\par
% Here is an example of such a notice and statement:\par
% \iffalse
%<*ignore>
% \fi
\begin{lstlisting}[language={[LaTeX]TeX}]
%%% pig.dtx
%%% Copyright 2005 M. Y. Name
%%
%% This work may be distributed and/or modified under the
%% conditions of the LaTeX Project Public License, either version 1.3
%% of this license or (at your option) any later version.
%% The latest version of this license is in
%%   http://www.latex-project.org/lppl.txt
%% and version 1.3 or later is part of all distributions of LaTeX
%% version 2005/12/01 or later.
%%
%% This work has the LPPL maintenance status `maintained'.
%% 
%% The Current Maintainer of this work is M. Y. Name.
%%
%% This work consists of the files pig.dtx and pig.ins
%% and the derived file pig.sty.
\end{lstlisting}
% \iffalse
%</ignore>
% \fi
% Given such a notice and statement in a file, the
% conditions given in this license document would apply, with
% the `Work' referring to the three files
% {\ttfamily{}pig.dtx}\thinspace, {\ttfamily{}pig.ins}\thinspace, and {\ttfamily{}pig.sty} (the last being generated
% from {\ttfamily{}pig.dtx} using {\ttfamily{}pig.ins}), the `Base
%   Interpreter' referring to any
% `\LaTeX{}-Format', and both `Copyright
%   Holder' and `Current Maintainer'
% referring to the person
% M.~Y.~Name\index{!}.\par
% If you do not want the Maintenance section of
% \textsc{lppl} to apply to your Work, change
% `maintained' above into
% `author-maintained'. However, we recommend that
% you use `maintained' as the Maintenance
% section was added in order to ensure that your Work remains
% useful to the community even when you can no longer maintain
% and support it yourself.\par
% \subsubsection{Derived Works That Are Not Replacements}\label{NotReplacements}
% Several clauses of the \textsc{lppl} specify
% means to provide reliability and stability for the user
% community. They therefore concern themselves with the case
% that a Derived Work is intended to be used as a (compatible or
% incompatible) replacement of the original Work. If this is not
% the case (e.g., if a few lines of code are reused for a
% completely different task), then clauses 6b and 6d shall not
% apply.\par
% \subsubsection{Important Recommendations}\label{Recommendations}
% \paragraph[Defining What Constitutes the Work]{Defining What Constitutes the Work :}
% The \textsc{lppl} requires that distributions
%   of the Work contain all the files of the Work.  It is
%   therefore important that you provide a way for the licensee
%   to determine which files constitute the Work.  This could,
%   for example, be achieved by explicitly listing all the files
%   of the Work near the copyright notice of each file or by
%   using a line such as:\par
% \iffalse
%<*ignore>
% \fi
\begin{lstlisting}[language={[LaTeX]TeX}]
%% This work consists of all files listed in manifest.txt.
\end{lstlisting}
% \iffalse
%</ignore>
% \fi
% in that place.  In the absence of an unequivocal list it
%   might be impossible for the licensee to determine what is
%   considered by you to comprise the Work and, in such a case,
%   the licensee would be entitled to make reasonable
%   conjectures as to which files comprise the Work.\par
