# WORK: It aims to :
#
#      - Treat output timing from the osxxlf target for 
#        mon, mpi runs
#     *- compare it to a reference version 
#
# * this step is performed only if a reference tag 
#   is specified with the -t option and if files exist.
#   See the Makefile under ./config/HEAD directory
