require 'chef/cookbook/file_vendor'
# This FileVendor loads files from Chef::Config.cookbook_path. The
# thing that's sort of janky about this FileVendor implementation is
# that it basically takes only the cookbook's name from the manifest
# and throws the rest away then re-builds the list of files on the
# disk. This is due to the manifest not having the on-disk file
# locations, since in the chef-client case, that information is
# non-sensical.
