You need to add the following code to your config.rb file:

activate :s3_metadata do |config|
  config.bucket                = 'my.bucket.com' # The name of the S3 bucket you are targetting. This is globally unique.
  config.region                = 'us-west-1'     # The AWS region for your bucket.
  config.aws_access_key_id     = 'AWS KEY ID'
  config.aws_secret_access_key = 'AWS SECRET KEY'
  config.after_build           = false # We chain after the build step by default. This may not be your desired behavior...
end

The s3_metadata method set a metadata for S3 object:

# Set suitable Content-Type
s3_metadata('feeds/feed.rss', 'Content-Type', 'rss/xml')
s3_metadata('archives.tar.gz', 'Content-Type', 'application/x-gzip')

# Disable caching
s3_metadata('index.html', 'Cache-Control', nil)
s3_metadata('index.html', 'Expires', nil)

First argument is key for S3 object, second and third arguments is key and value for metadata.

A Debt of Gratitude

I used middleman-sync and middleman-s3_redirect as a template for building a Middleman extension. My gratitude goes to @karlfreeman and @fredjean.
