Deployment

It is a two-head environment:

• the "pre-prod" (staging) environment is https://staging.ruby-lang.org
• the production server is https://www.ruby-lang.org

The staging environment runs on the same hardware (same bay) as the production. It is deployed automatically by Travis CI when commits are pushed to the master branch.

Deploying www.ruby-lang.org is achieved by any editorial team's member, pushing it to the remote repository on Heroku.

git push heroku  # makes it live!
