  521	521	The Utils (and to a lesser extent TestUtils) module are intended to contain functions that could have
  522	522	come straight out of the standard library. The standard library is also another place to look for
  523	useful functions. The URL for the latest version is: \url{http://haskell.org/ghc/docs/latest/html/libraries/}.
  524	Particularly useful modules are\footnote{The URLs are a bit fragile for the latest version, but
  525	they are easy enough to find by searching the contents page at the URL given above}:
  523	useful functions. The URL for the latest version is: \url{http://haskell.org/ghc/docs/6.6/html/libraries/}.
  524	Make sure you always refer to the documentation for the lowest compiler version we support (currently
  525	6.6) to avoid accidentally using a function that is only available in a later version.
  526
  527	Particularly useful modules are:
  526	528
  527	529	\begin{itemize}
  528	\item \lstinline|Data.List| -- Contains various helper functions for dealing with lists, including map,
  530	\item \href{http://haskell.org/ghc/docs/6.6/html/libraries/base/Data-List.html}{\lstinline|Data.List|}
  531	-- Contains various helper functions for dealing with lists, including map,
  529	532	foldl, zip, sum, and many others\footnote{A lot of these are technically in the standard Prelude, but
  530	533	it's easy to find all the documentation in one place in the \lstinline|Data.List| module, as well
  531	534	as several useful functions not in the Prelude.}. Probably the most useful module.
  532	\item \lstinline|Control.Monad| -- Contains all the general monadic helper functions, such as
  535	\item \href{http://haskell.org/ghc/docs/6.6/html/libraries/base/Control-Monad.html}{\lstinline|Control.Monad|}
  536	-- Contains all the general monadic helper functions, such as
  533	537	mapM, foldM, sequence. If you ever find yourself struggling to manipulate monadic types, there
  534	538	may be something to help you in here.
  535	\item \lstinline|System.IO| -- Contains all the functions for printing to the screen, reading from
  539	\item \href{http://haskell.org/ghc/docs/6.6/html/libraries/base/Control-Monad.html}{\lstinline|System.IO|}
  540	-- Contains all the functions for printing to the screen, reading from
  536	541	files, etc.
  537	542	\end{itemize}
  538	543
  539	Other useful modules are \lstinline|Data.Maybe|, \lstinline|Data.Generics|, \lstinline|Data.Map|,
  540	\lstinline|Data.Set| and \lstinline|Test.HUnit|.
  544	Other useful modules are
  545	\href{http://haskell.org/ghc/docs/6.6/html/libraries/base/Data-Maybe.html}{\lstinline|Data.Maybe|},
  546	\href{http://haskell.org/ghc/docs/6.6/html/libraries/base/Data-Generics.html}{\lstinline|Data.Generics|},
  547	\href{http://haskell.org/ghc/docs/6.6/html/libraries/base/Data-Map.html}{\lstinline|Data.Map|},
  548	\href{http://haskell.org/ghc/docs/6.6/html/libraries/base/Data-Set.html}{\lstinline|Data.Set|} and
  549	\href{http://haskell.org/ghc/docs/6.6/html/libraries/HUnit/Test-HUnit.html}{\lstinline|Test.HUnit|}.
