 \chapter{Conclusion}\label{ch:conclusion}
 
-Lorem Ipsum.
+This work presented \texttt{intercept.so}, a shared object file intended to be preloaded using \texttt{LD\_PRELOAD}, which may be used to intercept function calls on Linux systems.
+Furthermore, a tool to use this shared object easier---the \texttt{intercept} Python program---was presented.
+By using preloading to hook/intercept function calls, the overhead and performance degradation is negligible for the purpose of testing student submissions.
+To make use of intercepted function calls, some techniques of automatic testing of simple C programs were discussed.
+
+The source code of the programs developed in this work is attached below.
+(Not all PDF viewers may open/download attachments.)
