require 'chef/mixin/shell_out'
class Chef
# Generates file diffs.
#--
# TODO/BUG:
# This is a quick hack. The final implementation should do the following:
# * Support a max file size above which diffs won't be attempted.
# * Support a max diff size above which results will be thrown out.
# * implement diffs in a way that will be performant and not depend on the diff(1) program.
# Xdiff looks pretty hot for this: http://XMailServer.Org/xdiff.html
