    # NOTE: if you have a sudo requires tty you have to change the require tty line in your sudeors file

    # Make sure you can write to the dir:
    `sudo chown -R ec2-user:ec2-user /var/app/current`

    # 1. Read STDIN (Format: "from_commit to_commit branch_name")
    from, to, branch = ARGF.read.split " "

    # 2. Only deploy if master branch was pushed
    # Uncomment to ensure this only happens on master branch
    # if (branch =~ /master$/) == nil
    #     puts "Received branch #{branch}, not deploying."
    #     exit
    # end

    # 3. Copy files to deploy directory
    #you can change the deploy_to_dir to whatever is needed

    #deploy_to_dir = File.expand_path('../deploy')
    deploy_to_dir = '/var/app/current/'


    `GIT_WORK_TREE="#{deploy_to_dir}" git checkout -f #{branch}`
    puts "DEPLOY: #{branch} (#{to}) copied to '#{deploy_to_dir}'"
