+To build this example, modify the components.py file
+to take into account your configuration.
+
+1- your prerequisite file 
+2- your KERNEL_ROOT_DIR
+
+Then set the environment (including PYTHONPATH for YACGEN, ../.. from here and execute components.py ::
+
+  source <your prerequisite file>
+  python components.py
+
+You should get a SALOME module in source form (cppcompos_SRC), its installation (install) and
+a SALOME application (appli) composed of modules KERNEL, GUI, YACS and cppcompos.
+
+To run a coupling:
+
+ 1. start SALOME in background : ./appli/runAppli -t
+ 2. start a SALOME session : ./appli/runSession
+ 3. start YACS coupler with coupling file : driver coupling.xml
+ 4. examine output files in /tmp
+ 5. shutdown SALOME : shutdowSalome.py
+ 6. exit session : CTRL-D (or exit)
