This entry point is called from the function scriba_DoSyntaxAnalysis implemented in the file `scriba.c' when the syntax analyzer has finished.
The only difference between this entry point and the entry point PreprocessorExEnd is that at this point the field pCommandList in the peXobject object structure already points to the list of nodes.
The argument p points to the actual peXobject syntax analysis object structure. The function has to return zero or the error code and should set the parameter *pCmd to PreprocessorContinue, PreprocessorDone, or PreprocessorUnload.
