Yes that's about all you have to do

My main C-Script has...

include <PPE_Start.c>;

...and in PPE_Start.c I have...

#define PRAGMA_PATH "shade-c" //if you use Shade-C
#include <acknex.h>
#include <default.c>
#include "mtlView.c"
#include "sc_core.c"; //if you use Shade-C

...because I also use Shade-C HDR.

Now you can use and chain stages...

camera.stage = viewBleach;
viewBleach.stage = viewDesat;
viewDesat.stage = viewColor; //viewBleach,Desat&Color are my own views- i can't remember the original GS PPE view names

...or/also Shade-C...

sc_setup();

...that's all.

Btw:
If you want antialiasing you will have to use ChrisB fullscreen antialiasing plugin...
http://www.opserver.de/ubb7/ubbthreads.php?ubb=showflat&Number=263055#Post263055
...because d3d_antialias will now be totally useless

Btw Btw:
I forgot very, very important thing
In PPE_Start.c you need a startup function because your function main is in C-Script and Lite-C can't see actions assigned in WED or C-Script.
So you need...

void ppe_startup()

...and everything works out.
