piapp> exec multicurve  
 OR exec multicurve.pic

5/ axel.pic :  Some options for axes

6/ addelts.pic : How to add some graphic objects (circles, rectangles, text) 
   to a plot, in this case a function plot

csh> make exmodule.so 
11.b/ Execute the script exmod.pic 
  ---> new commands are added to piapp

12/ exmoddrw.pic exmoddrw.cc 
csh> make exmoddrw.so 
 in piapp> exec exmoddrw.pic
  ---> extends piapp graphic capability by a new drawer
