I am trying to compile the following document:
\documentclass[a4paper,11pt]{scrartcl}
\usepackage[supstfm=libertinesups,supscaled=1.2,raised=-.13em]{superiors}
\begin{document}
a
\end{document}
The second line of code is taken from the package documentation (beginning of page 2, see here: https://anorien.csc.warwick.ac.uk/mirrors/CTAN/fonts/superiors/doc/superiors-doc.pdf). I am presented with the error:
Unknown option `supstfm=libertinesups' for package `superiors'.
Unknown option `supscaled=1.2' for package `superiors'.
Unknown option `raised=-.13em' for package `superiors'.
Why can I not use the "superiors" package with any options?
Cannot load superiors with any KOMA class or package.
So you can not use it withscrartcl
