% Simple code examples
% ====================
% Box for example code next to the rendered example.
%
% Arguments:
% 1. Label.
% 2. Content path without extension. If a corresponding PDF file exists, it gets included as an image. Otherwise, the LaTeX code gets rendered directly.
% 3. Caption.
\newcommand\example[3]{
	\Example{#1}{#2}{#2}{#3}

% Extended code examples
% ======================
% Box for example code next to the rendered example.
% Depending on the third argument, the source path for the right-side rendering can differ from the source path of the left-side listing.
% Useful if only an excerpt of the document to be rendered affects the entire output.
%
% Arguments:
% 1. Label.
% 2. Content path without extension. If a corresponding PDF file exists, it gets included as an image. Otherwise, the LaTeX code gets rendered directly.
% 3. Alternative path for Rendering (c.f. 2.)
% 4. Caption.
