+This coursework is worth 10\% and is due on XXXX at
 16:00. You are asked to implement a regular expression matcher.
 
+Make sure the files
+you submit can be processed by just calling \texttt{scala
+  <<filename.scala>>}.\bigskip 
+
+\noindent
+\textbf{Important:} Do not use any mutable data structures in your
+submissions! They are not needed. This excluded the use of
+\texttt{ListBuffer}s, for example. Do not use \texttt{return} in your
+code! It has a different meaning in Scala, than in Java.
+Do not use \texttt{var}! This declares a mutable variable. Feel free to
+copy any code you need from files \texttt{knight1.scala},
+\texttt{knight2.scala} and \texttt{knight3.scala}. Make sure the
+functions you submit are defined on the ``top-level'' of Scala, not
+inside a class or object.
