 '''Except if you develop the routing module or if you make changes related to reading and writing files or changing the grid information''', you don't need to worry about
 the parallelization. However, you have some rules to respect :
- * 1. Use the subroutines called restget_p, restput_p and getin_p instead of restget, restput and getin. Note that all processes should call these subroutines _p and not only the master. 
- * 2. Exception : if you '''restart a scalar''', you have to use restget followed by a bcast command :
+ * Use the subroutines called restget_p, restput_p and getin_p instead of restget, restput and getin. Note that all processes should call these subroutines _p and not only the master. 
+ * It is now possible to use restget_p also for scalar values. Before a workaround where only the master MPI did the call was used, see following example:

- for restput, follow the example :
-{{{

-       var_name = 'day_counter'
-       xtmp(1) = day_counter

-    ENDIF

- Note that only the master does the call to restget and restput.
