根据yaml文件的内容打包指定的文件

package.rb

#!/usr/bin/env ruby
#coding: utf-8

require 'yaml'
require 'fileutils'

config_file_path = 'package.yaml'

# get related diretories information & prepare
src = Dir.getwd
dst = File.expand_path('_package', src)

Dir.mkdir(dst) if not File.exist?(dst)

# read structure data
files = YAML.load_file(config_file_path)

# fetch files and keep their hierarchy
files.each do |v|
  dir = File.expand_path(File.dirname(v), dst)
  FileUtils.mkdir_p(dir) if not File.exist?(dir)
  FileUtils.cp_r(File.expand_path(v, src), File.expand_path(v, dst))
end

package.yaml

- dir1
- dir2
- dir3/file1.rb
