What would you like to do?
Download my destroyallsoftware videos

This script will download all ios files in the current directory.

It will check for already downloaded files in the current directory.

It can work interactively or with a config.yml (copy from config.yml.template)

usage

das = DasDownloader.new
das.sign_in.download_videos

or

ruby das.rb

Any idea how to TDD this?

Other comments?
