Verzeichnis macros/latex/contrib/docshots

This LaTeX package helps you show TeX code next to their PDF snapshots, in two-column formatting. You can use it either in .dtx documentation or in .tex file.

First, install it from CTAN and then use like this:

\documentclass{article}
\usepackage{docshots}
\begin{document}
Here is how you can use \LaTeX:

\begin{docshot}
\documentclass{article}
\pagestyle{empty}
\begin{document}
  Hello, \LaTeX!
\end{document}
\end{docshot}

For more informaiton, read \TeX{} Book by Donald Knuth.
\end{document}

Otherwise, you can download docshots.sty and add to your project.

If you want to contribute yourself, make a fork, then create a branch, then run l3build ctan in the root directory. It should compile everything without errors. If not, submit an issue and wait. Otherwise, make your changes and then run l3build ctan again. If the build is still clean, submit a pull request.
