Overview

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)
