# Re-define regular expression (REGEX) global variable to reduce

# reduce the amount files find, the regular expression is
# evaluated in the whole path. This way, when the regular
# expression is specified, we need to build it in a way that
# matches the whole path. Doing so each time we pass a `--filter'
# command-line argument may be a tedious task, so, in the sake of
# reducing some typing, we prepare the regular expression here to
# match the whole path using the regular expression provided by
# the user as pattern.
