% \section{Introduction}
% The \PrintPackage{doclicense} 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}
% Just load the package(s) placing
% \begin{quote}
%   |\usepackage{| \\
%   |%  babel,| \\
%   |%  hyperref,| \\
%   |%  hyperxmp,| \\
%   |  doclicense,| \\
%   |}|
% \end{quote}
% in the preamble of your \LaTeXe{} source file. This will select the default
% license which is \doclicenseNameRef, currently. Please always set your
% license explicitly as package options like so:
%
% \begin{quote}
%   |\usepackage{| \\
%   |%  babel,| \\
%   |%  hyperref,| \\
%   |%  hyperxmp,| \\
%   |}| \\
%   |\usepackage[| \\
%   |  type={CC},| \\
%   |  modifier={by-sa},| \\
%   |  version={3.0},| \\
%   |]{doclicense}|
% \end{quote}
%
% This will explicitly set the license to \doclicenseNameRef.
%
% If the \PrintPackage{hyperxmp} package is loaded, then the options
% \PrintOptionF{pdflicenseurl} and \PrintOptionF{pdfcopyright} will be set
% by \PrintPackage{doclicense} to the corresponding values
% (\enquote{\url{\doclicenseURL}} and \enquote{\doclicenseLongText{}}).
%
% \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.
%
% Allows to
% 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.
%
% As \DescribePara{version} there can be more than one version of a license, the version can also be set.
%
% 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:

%
%
%
%
% \end{eqlist}
%
% Image position for \cmd{\doclicenseThis}: right (default) or left.
% \DescribePara{imageposition}
%
% Default image width for the license image.
% \DescribePara{imagewidth}
%
% Distance between text and image in \cmd{\doclicenseThis}.
% \DescribePara{imagedistance}

% Select different variations of license images.
% \DescribePara{imagemodifier}
% For example, Creative Commons provides sometimes 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 money unit.
% By default the by-nc image would be used but you can change this with:
% \begin{quote}
%   |\usepackage[| \\
%   |  imagemodifier={-eu},| \\
%   |]{doclicense}|
% \end{quote}
%
% Note that if French or German is set as language then \enquote{-eu} will be used as
% default for this option.
%
% Currently supported are \enquote{-eu} and \enquote{-us}.
%
% 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 documentation.
% \cmd{\doclicenseThis} did not produce a hyphenation in case of this
% documentation 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}
%
% \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{\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{\input} the license text file.
%
% \DescribeMacro{\doclicenseFullText}
% Nicely 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.
%
%
% \DescribeMacro{\doclicenseIcon}
% Expands to a icon of the license. Example:
% \enquote{\doclicenseIcon{}}. This macro is based on the
% \PrintPackage{ccicons} package.
%
% \DescribeMacro{\doclicenseTypeIcon}
% Expands to a icon of the license type. Example:
% \enquote{\doclicenseTypeIcon{}}. 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.
%
% \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
%
% \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
% licenses.

% \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 (modify and run the
% \path{run_tests} script) 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.
