\begin{document}
The \autodoc:package{scalebox} package allows to scale any content by some horizontal
and vertical ratios, by issuing the command
\autodoc:command{\scalebox[xratio=<number>, yratio=<number>]{<content>}},
where the ratios are optional non-null numbers (defaulting to 1).
The content is placed in a box and scaled.

Here is an \scalebox[xratio=0.75, yratio=1.25]{example}.
