+#
 #  - add the binary name into the noinst_PROGRAMS variable
 #  - add a rule to compile the program, inspired from the existing ones
+#  - add a tesh file running it in several conditions. 
+#    Write the file taking the others as example, and after reading
+#    <simgrid>/tools/tesh/README.tesh
+#  - List the tesh file in the TESTS variable so that it gets tested on make check
