Originally, I had it in mind to move letsencrypt-auto inside this dir. However, now we'd like to copy it or link it to the root level, where people are used to finding it (at least for awhile). Since it would be confusing to have a letsencrypt-auto and a letsencrypt_auto right next to each other, we rename this folder.
