How do I install ActiveSupport for plain Ruby scripts?

Gemfile: gem 'activesupport', bundle install. Or gem install activesupport. Require selectively.

What ActiveSupport methods work best in Ruby scripts?

.blank?, .present?, integer/time (3.days.ago), string (camelize, pluralize), array.in_groups_of, hash.with_indifferent_access.

Does ActiveSupport slow down small Ruby scripts?

Full require adds 200ms boot, 50MB RAM. Selective? Negligible — under 50ms, tiny footprint.
