Overview

github.com/aussiegeek/rubyzip/blob/master/samples/example_recursive.rb This is a simple example which uses rubyzip to recursively generate a zip file from the contents of a specified directory. The directory itself is not included in the archive, rather just its contents.

Usage: dir_to_zip = “/tmp/input” out_file = “/tmp/out.zip” zf = Zippy.new dir_to_zip, out_file zf.write

Or: z = Zippy.new(directory_to_zip, output_file) { |f| f.include? ‘html’ } z.write
