%
% \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{}}).
%
% \bigskip
%
% The first parameter is \enquote{\PrintOptionF{type}}. \DescribePara{type}
% This sets the license type. Like in this 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.
%
% The \DescribePara{modifier} next parameter is \enquote{\PrintOptionF{modifier}} which allows to
% select different subclasses of a license. In this
% 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}.
% Currently only English and German are supported.
%
% Default image width for the license image.
% \DescribePara{imagewidth}
%
% This options was added to support variations in the 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}{donwload 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 German is set as language then \enquote{-eu} will be used as
% default for this option.
%
% Currently supported are \enquote{-eu} and \enquote{-us}.
%
% \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{\doclicenseIcon}
% Expands to a icon of the license. Example:
% \enquote{\doclicenseIcon{}}. This macro is based on the
% \PrintPackage{ccicons} package.
%
% \DescribeMacro{\doclicenseImage}
% This is kind of similar with \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.
%
% \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
