-
-\begin{itemize}
-\item Make sure the files you submit can be processed by just calling\\
-  \mbox{\texttt{scala <<filename.scala>>}} on the commandline. Use the
-  template files provided and do not make any changes to arguments of
-  functions or to any types. You are free to implement any auxiliary
-  function you might need.
-
-\item Do not use any mutable data structures in your
-submissions! They are not needed. This means you cannot create new 
-\texttt{Array}s or \texttt{ListBuffer}s, for example. 
-
-\item Do not use \texttt{return} in your code! It has a different
-  meaning in Scala, than in Java.
-
-\item Do not use \texttt{var}! This declares a mutable variable. Only
-  use \texttt{val}!
-
-\item Do not use any parallel collections! No \texttt{.par} therefore!
-  Our testing and marking infrastructure is not set up for it.
