{protocol.cx, protocol.hx, protocol.sys, 
 protocol.pro} --> prepro ---> protocol.cxx protocol.hxx

To change configuration (location) of protocols in Processes, 
change only the .sys, .pro; recompile with prepro to get new 
.cxx and new .hxx.  (.cx and .hx - are protocol specific).  

prepro makes agent/real services as specified in the .pro/.sys.
