# This is an example script, which can be used to rename large amount
# of steps. It's kind of a hack, since this is a Cucumber "formatter".
# However, it does its job pretty ok.
#
# Usage:
# 1) Add step-to-be-renamed and rename method to `replaces` hash
# 2) Run: cucumber features --format Rename::GivenListingRenamer
