# the overwriting policy can receive
# objects from many different crit_action_* classes
# - crit_constant_action() used here does always the same
# action on Data and EA+FSA when a conflict arise that
# would lead to overwriting
# - testing(criterium) the action depends on the evaluation
# of the provided criterium (see below)
# - crit_chain() + add(crit_action) performs the different
# crit_actions added in sequence the first one that provides
# an action for Data and/or EA+FSA is retained. If no action
# is left undefined the following crit_action of the chain are
# not evaluated
#
# for the testing crit_action inherited class, we need to provide
# a criterium object. Here too there is a set of inherited classes
# that come to help:
# - crit_in_place_is_inode
# - crit_in_place_is_dir
# - crit_in_place_is_file
# - ...
# - crit_not (to take the negation of the given criterium)
# - crit_or + add_crit() + add_crit() ... makes the logical OR
# - crit_and + add_crit() + add_crit()... for the logical AND
# - crit_invert for the in_place/to_be_added inversion
# Read the manual page about overwriting policy for details
# but in substance the criterum return true of false for each
# file in conflict and the object if class testing that uses
# this criterium applies the action given as "go_true" or the
# action given as "go_false" in regard of the provided result
