-\section{\acrlong{TOP}}
-\gls{TOP} is a recent new programming paradigm implemented as
-\gls{iTasks}~\cite{achten_introduction_2015} in
-the pure lazy functional language \gls{Clean}

-\section{\acrlong{EDSL}s}
-\glspl{mTask} are expressed in a class based shallowly embedded \gls{EDSL}.
-There are two main types of \glspl{EDSL}.

-\todo{Show that class based has the best of both worlds}

-\section{Devices}
-The client code for the devices is compiled from one codebase. For a device to
-be eligible for \glspl{mTask} it must be able to compile the shared codebase
-and implement (part of) the device specific interface. The shared codebase only
-uses standard \gls{C} and no special libraries or tricks are used. Therefore
-the code is compilable for almost any device or system. Note that it is not
-needed to implement a full interface\todo{handshake}. The full interface,
-listed in Appendix~\label{app:device-interface}\todo{update interface listing},
-also includes functions for accessing the peripherals that not every device
-might have. Devices can choose what to implement by setting the correct macros
-in the top of the file.
-
-\subsection{Specification}
-Devices are stored in a record type and all devices in the system are stored in
-a \gls{SDS} containing all devices. From the macro settings in the interface
-file a profile is created for the device that describes the specification. When
-a connection between the server and a client is established the server will
-send a request for specification. The client will serialize his specs and send
-it to the server so that the server knows what the client is capable of. The
-exact specification is listed in Listing~\ref{lst:devicespec}

+\section{mTasks}
+\subsection{\gls{EDSL}}
+The \gls{mTask}-\gls{EDSL} contains several classes that need to be implemented
+by a type for it to be an \gls{mTask}. For numeric and boolean arithmetic the
+classes \texttt{arith} and \texttt{boolExpr} are available and listed in a
+shortened version in Listing~\ref{lst:arithbool}. All classes are to be
+implemented by types of kind \texttt{*->*->*} a type \texttt{v t p},
+respectively a view with a type and the role.
+
+\texttt{lit} lifts a constant to the \gls{mTask} domain. For a type to be a
+valid \gls{mTask} type it needs to implement the \texttt{mTaskType} class. The
+binary operators work as expected.
+
+\begin{lstlisting}[language=Clean,label={lst:arithbool},
+	caption={Basic classes for expressions}]
+class mTaskType a | toByteCode, fromByteCode, iTask, TC a
+
+class arith v where
+  lit :: t -> v t Expr | mTaskType t
+  (+.) infixl 6 :: (v t p) (v t q) -> v t Expr | type, +, zero t & isExpr p & isExpr q
+  ...
+class boolExpr v where
+  (&.) infixr 3 :: (v Bool p) (v Bool q) -> v Bool Expr | isExpr p & isExpr q
+  Not           :: (v Bool p) -> v Bool Expr | isExpr p

+\subsection{Tasks}
+
+\subsection{Shares}
+Shares can live on multiple clients at the same time. For every share created
+for an \gls{mTask} a real \gls{SDS} is created that mirrors the value on the
+client. All shares currently in use are stored in a system-wide \gls{SDS} in
+such a way that the actual share can be retrieved at any moment. All shares
+have a unique numeric identifier and an initial value.
