          This creates commands for creating AWS users, buckets an versioning policies and CloudFront. 
          It also guides you to set up the necessary environment.

          You will be asked for:
          (- installation of aws-cli, if not yet done)
          (- setting up aws user `renuo-app-setup`, if not yet done)
          - project name and suffix so that the script can respect our naming conventions
          - the Redmine project name to tag buckets for AWS billing references
          - whether you want to setup CloudFront to deliver assets via S3

          The generated commands do the following:
          - create an IAM user for each environment (master, develop, testing) and add it to the renuo apps group.
          - create S3 buckets for each user who owns it
          - tag the buckets
          - enable versioning for master buckets
          (- set up a CloudFront distribution for each environment with the default config or plus alias if configured)
