# There are 3 ways of passing `reek` a configuration file:
# 1. Using the cli "-c" switch
# 2. Having a file ending with .reek either in your current working
# directory or in a parent directory
# 3. Having a file ending with .reek in your HOME directory
#
# The order in which ConfigurationFileFinder tries to find such a
# configuration file is exactly like above.
