+The \mpgt consists of the \ggui and the \gtg.\\
 \begin{compactitem}
 \item The \ggui tool is the graphical interface tool for editing MP Code and for running the \gtg engine to view generated traces.
 \item The \gtg tool compiles MP Code into traces that the \ggui can read and graph.\\
 \end{compactitem}
 
 \subsection{Compatibility}
-\ggui Version 0.3.0 is compatible with \mphoenix Version 4 pre-alpha and \gtg Version 4 pre-alpha.
