%
% \section{Introduction}
% The \PackageName{} package allows you to put your document under a
% license and include a link to read about the license or include an icon or
% image of the license.  Currently, only \doclicenseLongType is supported but this
% package is designed to handle all kinds of licenses. See \nameref{sec:contributing}.
%
% \section{Usage}
% The package can be used like in this mini working example:
%
% \begin{quote}
%   |\documentclass[english]{article}| \\
%   |\usepackage[| \\
%   |  type={CC},| \\
%   |  modifier={by-sa},| \\
%   |  version={4.0},| \\
%   |]{doclicense}| \\
%   |\begin{document}| \\
%   |\doclicenseThis%| \\
%   |\end{document}|
% \end{quote}
%
% This will explicitly set the license to \doclicenseNameRef.
%
% With the default settings and if the \PrintPackage{hyperxmp} package is
% installed, it will be loaded and the options \PrintOptionF{pdflicenseurl}
% and \PrintOptionF{pdfcopyright} will be set by \PackageName{} to the
% corresponding values (\enquote{\url{\doclicenseURL}} and
% \enquote{\doclicenseLongTextForHyperref{}}). This embeds license metadata
% into the PDF which proper PDF readers can show. For example Evince shows it
% in the \enquote{Document License} tab under \enquote{Properties}. You may
% check this manual for how your PDF reader handles such metadata.
%
% In case you are using other packages to manipulate the metadata which is
% incompatible to the use of hyperxmp, e.\,g. \PrintPackage{pdfx} you can use
% the \PrintOptionF{hyperxmp=false} option to disable this automatism. If
% \PrintPackage{pdfx} is loaded before \PrintPackage{doclicense} or if
% \PrintPackage{hyperxmp} is not installed this automatism is disabled.
% In these cases a warning is emitted to inform you about the reason.
% The warning will not show up if \PrintOptionF{hyperxmp} is set to
% \PrintOptionF{false}.
%
% Also note that \PrintPackage{hyperxmp} is not loaded when
% \PrintPackage{silence} was loaded. This is because when both of those
% packages are loaded, compilation runs into an endless loop.
%
% \section{Dependency packages and load order}
%
% \PackageName{} will ensure that the following packages are loaded by default.
% You don't need to do anything extra as long as you are fine with the default options
% of those packages:
%
% \begin{eqlist}
%   \item[\PrintPackage{ccicons}] To typeset icon versions of the Creative Commons licenses.
%   \item[\PrintPackage{graphicx}] To include images/buttons of the Creative Commons licenses.
%   \item[\PrintPackage{hyperxmp}] To write license information into the metadata section of the generated PDF.
%   \item[\PrintPackage{hyperref}] To typeset hyperlinks/URLs that are clickable.
%   \item[\PrintPackage{csquotes}] To offload localization of quotes depending on document language.
% \end{eqlist}
%
% Load order is important for some of those packages.
% Here are the constraints that you will need to consider when you decide to
% load the packages yourself or other packages that you use load them:
%
% \begin{itemize}
%   \item \PrintPackage{hyperxmp} should be loaded before the setup of \PrintPackage{hyperref} is called.
%   \item \PrintPackage{csquotes} should be loaded before
%     \PrintPackage{biblatex} because otherwise \PrintPackage{biblatex} will
%     define the \cmd{\enquote} in a way that is not compatible with
%     \PackageName{}.
%   \item The position of loading \PackageName{} is decoupled from the load
%     order because interaction and loading of dependency packages is done via a
%     hook at the end of the preamble.
% \end{itemize}
%
%
% \section{Package options}
%
% Sets the license type. \DescribePara{type}
% Like in the previous example, the type can be
% \enquote{CC} to cover all the \doclicenseLongType licenses.
% Please make sure that the type is all uppercase. See the \nameref{sec:supported-licenses} section for a complete list.
% This is a required option since v2.0.0.
%
% Allows to \DescribePara{modifier}
% select different subclasses of a license. In the
% example it is \enquote{by-sa}.
% Please make sure that the type is all lowercase. See the \nameref{sec:supported-licenses} section for a complete list.
% This is a required option since v2.0.0.
%
% As \DescribePara{version} there can be more than one version of a license, the version also needs to be set.
% This is a required option since v2.0.0.
%
% This package can output some texts like the long license name.
% \DescribePara{lang}
% Because of this, there needs to be a way to specify the language to use.
% If this parameter is omitted, then this package will default to
% \cmd{\languagename} which is normally set by packages like
% \PrintPackage{babel} or \PrintPackage{polyglossia}.
%
% Supported languages:
% ^^A Sorted alphabetically.
% \begin{itemize}
%   \item Austrian
%   \item Brazilian
%   \item Bulgarian
%   \item Catalan
%   \item Chinese: Note that you might need to pass \verb+lang={chinese-utf8}+ \verb+lang={chinese-tw}+, or \verb+chinese-gbk+.
%   \item Croatian
%   \item English
%   \item Esperanto
%   \item French
%   \item Galician
%   \item German
%   \item Greek
%   \item Italian
%   \item Japanese
%   \item Marathi: Note that Niranjan also translated the images which are considered unofficial by the package. Creative Commons has no plans to support additional currencies.
%   \item Polish
%   \item Portuguese
%   \item Russian
%   \item Spanish
%   \item Swedish
%   \item Swiss German
%   \item Ukrainian
% \end{itemize}
%
% Image position for \cmd{\doclicenseThis}: right (default) or left.
% \DescribePara{imageposition}
%
% Default image width for the license image.
% \DescribePara{imagewidth}
% Defaults to 10em.
%
% Distance between text and image in \cmd{\doclicenseThis}.
% \DescribePara{imagedistance}
% Defaults to 2em.

% Select different variations of license images.
% \DescribePara{imagemodifier}
% For example, Creative Commons provides more than one image for one version.
% See the \href{https://creativecommons.org/about/downloads}{download page}.
% You will note that there are by-nc.eu and by-nc which only differ in the currency.
% Based on the loaded language, the currency is set to a suitable default. You can change this with:
% \begin{quote}
%   |\usepackage[| \\
%   |  type={CC},| \\
%   |  modifier={by-nc},| \\
%   |  version={4.0},| \\
%   |  imagemodifier={-eu-88x31},| \\
%   |]{doclicense}|
% \end{quote}
%
% Also, there is 80x15 which uses letters instead of icons for the modifiers in the image.
% \begin{quote}
%   |\usepackage[| \\
%   |  type={CC},| \\
%   |  modifier={by-nc},| \\
%   |  version={4.0},| \\
%   |  imagemodifier={-eu-80x15},| \\
%   |]{doclicense}|
% \end{quote}
%
% If this is not given, we default to 88x31.
%
% Note that imagemodifier needs to assemble into a valid filename. Check
% what files the package ships with to understand what combinations can be
% used.
%
% For backwards compatibility, \enquote{-eu} is interpreted as \enquote{-eu-88x31}.
%
% This option allows you to specify
% \DescribePara{hyphenation}
% a macro name which is going to be expanded
% in the minipage environment of \cmd{\doclicenseThis}.
% That allows you to change the behaviour how \cmd{\doclicenseLongText} is
% typeset. By default, this option is not enabled.
%
% One possible use case is to set the option to \enquote{RaggedRight}.
% This will use the \cmd{\RaggedRight} macro provided by the
% \PrintPackage{ragged2e} package\footnote{The \PrintPackage{ragged2e} package will be loaded when it is required.}) with the intention of limiting the number of
% hyphenations while still allowing a hyphenation by typesetting
% \cmd{\doclicenseLongText} as ragged text.
%
% The idea of using ragged text is that the \cmd{\doclicenseLongText} is
% usually one or two full line and one half full line so avoiding hyphenations
% might look better compared to justified text.
%
% \enquote{RaggedRight} is also the setting used for this manual.
% \cmd{\doclicenseThis} did not produce a hyphenation in case of this
% manual but \TeX{} did fill up the first text line to it’s full width
% by adding additional space between words. This has been be avoided by setting
% the following option for this document:
%
% \begin{quote}
%   |\usepackage[| \\
%   |  hyphenation={RaggedRight},| \\
%   |]{doclicense}|
% \end{quote}
%
% Another option which can make sense is the \cmd{\raggedright} macro which
% more drastically limits the number of hyphenations. This can be set as shown
% below:
%
% \begin{quote}
%   |\usepackage[| \\
%   |  hyphenation={raggedright},| \\
%   |]{doclicense}|
% \end{quote}
%
% This option allows to disable the automatic loading of \PrintPackage{hyperxmp}.
% \DescribePara{hyperxmp}
% It's initialized to true. This might also be used to suppress the warning if
% \PrintPackage{hyperxmp} is not available or \PrintPackage{pdfx} was loaded before
% \PrintPackage{doclicense}.
%
% \section{Macros}
% \DescribeMacro{\doclicenseType}
% Expands to the type as set in the package options. Example: \enquote{\doclicenseType{}}
%
% \DescribeMacro{\doclicenseLongType}
% Same as \cmd{\doclicenseType} except that it expands to the long license
% type. Example: \enquote{\doclicenseLongType{}}
%
% \DescribeMacro{\doclicenseModifier}
% Expands to the modifier as set in the package options. Example: \enquote{\doclicenseModifier{}}
%
% \DescribeMacro{\doclicenseVersion}
% Expands to the version as set in the package options. Example: \enquote{\doclicenseVersion{}}
%
% \DescribeMacro{\doclicenseURL}
% Expands to the official URL about the license. Note that it expands to the
% raw URL string without the use of \cmd{\href} or similar. If you want the
% link to be clickable then you can use \cmd{\href} or \cmd{\url} from the
% \PrintPackage{hyperref} package or just read on because the following macros
% can also do this for your. Example:
% \enquote{\doclicenseURL{}}
%
% \DescribeMacro{\doclicenseName}
% Expands to the short name of the license. Example: \enquote{\doclicenseName{}}
%
% \DescribeMacro{\doclicenseLongName}
% Expands to the long name of the license. Example: \enquote{\doclicenseLongName{}}
%
% \DescribeMacro{\doclicenseNameRef}
% Same as \cmd{\doclicenseName} except that it links to the URL of the license.
% Example: \enquote{\doclicenseNameRef{}}
%
% \DescribeMacro{\doclicenseLongNameRef}
% Same as \cmd{\doclicenseLongName} except that it links to the URL of the
% license. Example:
% \enquote{\doclicenseLongNameRef{}}
%
% \DescribeMacro{\doclicenseText}
% Expands to a localized text which states that this document is licensed under
% the license. Example:
% \enquote{\doclicenseText{}}
%
% \DescribeMacro{\doclicenseLongText}
% Same as \cmd{\doclicenseText} except that it uses the long name of the license.
% Example: \enquote{\doclicenseLongText{}}
%
% \DescribeMacro{\doclicenseLongTextForHyperref}
% \hspace{2.5em}Same as \cmd{\doclicenseLongText} except that it does not contain \cmd{\href}
% and other complex macros. The purpose of this macro is to be used as value inside of \cmd{\hypersetup}.
% Example: \enquote{\doclicenseLongTextForHyperref{}}
%
% \DescribeMacro{\doclicensePlainFullText}
% Verbatim prints the full license text.
%
% ^^A Don’t ask why I inserted that line break … (LaTeX made the \doclicensePlainFullText red).
%
% An example can be found in the \nameref{sec:plain_license_text} section.
%
% \DescribeMacro{\doclicensePlainFullTextFileName}
% \hspace{2.5em}Expands to the file name which the \cmd{\doclicensePlainFullTextFileName} macro uses to \cmd{\verbatiminput} the license text file.
% Example: \enquote{\doclicensePlainFullTextFileName{}}
%
% \DescribeMacro{\doclicenseFullText}
% Pretty prints the full license text.
%
% ^^A Don’t ask why I inserted that line break … (LaTeX made the \doclicenseFullText red).
%
% An example can be found in the \nameref{sec:pretty_license_text} section.
%
% \DescribeMacro{\doclicenseFullTextFileName}
% Expands to the file name which the \cmd{\doclicenseFullText} macro uses to \cmd{\input} the license text file.
% Example: \enquote{\doclicenseFullTextFileName}
%
% \DescribeMacro{\doclicenseTypeIcon}
% Expands to an icon of the license type. Example:
% \enquote{\doclicenseTypeIcon{}}. This macro is based on the
% \PrintPackage{ccicons} package.
%
% \DescribeMacro{\doclicenseIcon}
% Expands to an icon of the license. Example:
% \enquote{\doclicenseIcon{}}. This macro is based on the
% \PrintPackage{ccicons} package.
%
% \DescribeMacro{\doclicenseImage}
% This is kind of similar to \cmd{\doclicenseIcon} but it will typeset an
% bigger pictogram of the license. Example:
% \enquote{\doclicenseImage}
%
% Note that you can change the image size with the \oarg{imagewidth} parameter
% like this:
% \enquote{\doclicenseImage[imagewidth=2em]}
%
% \begin{quote}
%   |\doclicenseImage[imagewidth=2em]|
% \end{quote}
%
% The images are bundled with the \PackageName{} package as vector graphics.
%
% \DescribeMacro{\doclicenseImageFileName}
% This macro expands to the file name of the image which the
% \cmd{\doclicenseImage} typesets.  You can use this file name with
% \cmd{\includegraphics} if you need more flexibility over how the image is
% typeset.
%
% The current file name is: \enquote{\doclicenseImageFileName}
%
% You do not have to worry about the file path. Normally your \LaTeX{} environment
% will find the image for you.
%
% The file extension is omitted which is good practice together with
% \cmd{\includegraphics} as it will pick the proper one itself.
%
% \DescribeMacro{\doclicenseThis}
% And last but not least there is the \cmd{\doclicenseThis} macro which will
% typeset the \cmd{\doclicenseText} next to the \cmd{\doclicenseImage} in a
% \enquote{minipage} environment.
% This will look like the following:
%
% \doclicenseThis
%
% \makeatletter
% \renewcommand{\doclicense@imagemodifier}{-80x15}
% And here is how it looks with the imagemodifier option set to \enquote{\doclicense@imagemodifier}:
%
% \doclicenseThis
% \renewcommand{\doclicense@imagemodifier}{-88x31}
% \makeatother
%
% \section{Supported licenses}
% \label{sec:supported-licenses}
%
% Currently only Creative Commons is supported.
% The license type, modifier and version should be based on
% \href{https://spdx.org/licenses/}{SPDX license identifiers}. Direct support
% for SPDX license identifiers should be considered when supporting new

% \section{Retired licenses}
%
% Licenses get updated and sometimes fully replaced.
% This section clarifies how \PackageName{} handles this.
%
% If there is consensus that the old license has no valid use case anymore and
% it is possible and allowed for everyone compiling a document to update the
% license, then the old license will be removed from \PackageName{} in the next
% major version.
%
% Otherwise, \PackageName{} will keep supporting it to ensure that documents
% using those licenses can still be compiled in the future.
%
% List of retired licenses:
%
% \makeatletter
% ^^A Sorted alphabetically.
% \begin{eqlist}
%   \item[CC-PDDC] Copyright-Only Dedication
% \end{eqlist}
% \makeatother
%
% \section{What license to choose for the document?}
%
% The list of available licenses is long (see
% \href{https://spdx.org/licenses/}{SPDX License List}). Only a (small) subset
% of them are a good choice for documentation. The \doclicenseLongType family
% seem to be a common choice as contributions to this package have shown. This
% package was translated to 15+ languages but no other license families have
% been added yet. With that, a link to
% \href{https://creativecommons.org/choose/}{Creative Commons: Choose a
% License} is probably justified if you have not done that already.
%
% \section{REUSE Specification}
%
% That clarifies the question under which license you want to put the document
% under, but in practice it might not be as easy as that.
% Under what license are the artifacts (images/figures/tables/source code
% listings) you are including? It would probably be useful to track such
% metadata along with the files. For this, the \href{REUSE
% Specification}{https://reuse.software/} can be used.
%
% The REUSE Specification is independent of \LaTeXe{} and more \enquote{low
% level} than this package.
% \PackageName{} might integrate with the REUSE Specification at a later point.
% Refer to \url{https://github.com/ypid/latex-packages/issues/72} for
% discussion how such an integration could look like.
%
% \section{Contributing}
% \label{sec:contributing}
% This package is being developed on GitHub: \url{\PackageURL}. When you want
% to modify the .sty file, make sure that you make your changes in the .dtx
% file instead, as the .sty file is automatically generated.
%
% In case you want to add a translation for your language then just copy the
% file \path{doclicense-english.ldf} and replace the \enquote{english} in
% the filename with your language code (same as the language code used by
% \PrintPackage{babel}) and translate the file.
% If there are multiple language
% codes which should map to the same translation then have a look at the file
% \path{doclicense-american.ldf}.
%
% When you are done and have tested your translation by modifying
% \path{test-package-option-matrix} and then running
% \enquote{./test-package-option-matrix mynewlanguage}), then please send me
% the translated file(s) either via Email or preferably by opening a pull
% request on GitHub so that I can include them in the next release.
%
% Note that the following development conventions are used for the package:
%
% \begin{itemize}
%   \item \href{https://reuse.software/spec/}{REUSE Specification 3.0}
%   \item \href{https://www.conventionalcommits.org/en/v1.0.0/}{Conventional Commits 1.0.0}
%   \item \href{https://semver.org/spec/v2.0.0.html}{Semantic Versioning 2.0.0}
