+Dette kurset er en introduksjon til Common Lisp for nybegynnere.  Vi
+vil ta for oss
+
+\begin{itemize}
+\item Litt Lisp-historie
+\item Lister
+\item Funksjoner
+\item Spesielle operatorer
+\item Funksjonell og imperativ programmering
+\end{itemize}
+
+\vspace{4mm}
+
+\textit{Varighet}: Ca. 2--3 timer\\
+\textit{Anbefalte forkunnskaper}:
+\begin{minipage}[t]{10cm}
+Noe programmeringserfaring i andre språk.\\
+Ingen kjennskap til Lisp forutsettes.
