# A general packaging (tar) middleware. Given the following options,
# it will do the right thing:
#
# * package.output - The filename of the outputted package.
# * package.include - An array of files to include in the package.
# * package.directory - The directory which contains the contents to
# compress into the package.
#
# This middleware always produces the final file in the current working
# directory (FileUtils.pwd)
