Drupal 7's new multilingual systems compilation

While creating mutlilingual Drupal sites is getting easier with each release, and each new major version of the contributed modules involved, it still requires you to understand the basic building blocks and plan ahead to find the right tools fit for your job. My article series is aimed at highlighting the thinking behind different components and detailing the sometimes admittedly obscure steps involved to set them up. Note that each article was (to my best attempt) accurate at the time of writing, and the articles are not updated as the tools change. I hope they will be useful for some time.
