# FakeFS::SpecHelpers provides a simple macro for RSpec example groups to turn FakeFS on and off.
# To use it simply require 'fakefs/spec_helpers', then include FakeFS::SpecHelpers into any
# example groups that you wish to use FakeFS in. For example:
#
# require 'fakefs/spec_helpers'
#
# describe "Some specs that deal with files" do
# include FakeFS::SpecHelpers
# ...
# end
#
# Alternatively, you can include FakeFS::SpecHelpers in all your example groups using RSpec's
# configuration block in your spec helper:
#
# require 'fakefs/spec_helpers'
#
# Spec::Runner.configure do |config|
# config.include FakeFS::SpecHelpers
# end
#
# If you do the above then use_fakefs will be available in all of your example groups.
#
require 'fakefs/safe'
