The files and directories obey the TDS standard. +% \begin{description} +% \item[\CTANinstall{install/macros/latex/contrib/transparent.tds.zip}] +% \end{description} +% \emph{TDS} refers to the standard ``A Directory Structure +% for \TeX\ Files'' (\CTANpkg{tds}).

For example, \TeX\,Live\ users run \verb|texhash| or +% \verb|mktexlsr|. +% +% \subsection{Some details for the interested} +% +% \paragraph{Unpacking with \LaTeX.} +% The \xfile{.dtx} chooses its action depending on the format: +% \begin{description} +% \item[\plainTeX:] Run \docstrip\ and extract the files. +% \item[\LaTeX:] Generate the documentation. +% \end{description} +% If you insist on using \LaTeX\ for \docstrip\ (really, +% \docstrip\ does not need \LaTeX), then inform the autodetect routine +% about your intention: +% \begin{quote} +% \verb|latex \let\install=y\input{transparent.dtx}| +% \end{quote} +% Do not forget to quote the argument according to the demands +% of your shell. +% +% \paragraph{Generating the documentation.} +% You can use both the \xfile{.dtx} or the \xfile{.drv} to generate +% the documentation. The process can be configured by the +% configuration file \xfile{ltxdoc.cfg}. For instance, put this +% line into this file, if you want to have A4 as paper format: +% \begin{quote} +% \verb|\PassOptionsToClass{a4paper}{article}| +% \end{quote} +% An example follows how to generate the +% documentation with pdf\LaTeX: +% \begin{quote} +%\begin{verbatim} +%pdflatex transparent.dtx +%makeindex -s gind.ist transparent.idx +%pdflatex transparent.dtx +%makeindex -s gind.ist transparent.idx +%pdflatex transparent.dtx +%\end{verbatim} +% \end{quote} +% +% \begin{History} +% \begin{Version}{2007/01/08 v1.0} +% \item +% First version. +% \end{Version} +% \begin{Version}{2016/05/16 v1.1} +% \item +% Documentation updates. +% \end{Version} +% \begin{Version}{2018/09/10 v1.2} +% \item +% Update for LuaTeX, remove dependency on Pdf\TeX\ command names. +% \end{Version} +% \begin{Version}{2018/11/18 v1.3} +% \item +% Added code for pgf compatibility, see https://github.com/ho-tex/transparent/issues/1 +% \end{Version} +% \begin{Version}{2019/11/29 v1.4} +% \item +% Documentation updates. +% \item +% Use \xpackage{iftex} package. +% \end{Version} +% \end{History} +% +% \PrintIndex +% +% \Finale +\endinput diff --git a/macros/latex/contrib/transparent/transparent.pdf b/macros/latex/contrib/transparent/transparent.pdf new file mode 100644 index 0000000000..3eec17c736 Binary files /dev/null and b/macros/latex/contrib/transparent/transparent.pdf differ -- cgit v1.2.3
