+\subject{Example of an Academic Paper\footnote{%
+  This document is an example setup for writing academic paper. While
+  it is optimized for Springer's LNCS class, it uses a Koma Script
+  LaTeX class to avoid the need for distributing \texttt{llncs.cls},
+  which would violate Springer's copyright. This example has been
+  published at CICM 2018:

+      Computer Mathematics (CICM). Lecture Notes in Computer Science
