# Powerpack
Powerpack offers some useful extensions to the standard Ruby classes (kind of like `ActiveSupport`, but less ambitious and more modular).
## Installation
Add this line to your application's `Gemfile` (if you're using `bundler`, that is):
gem 'powerpack'
And then execute:
$ bundle
Or install it yourself as:
$ gem install powerpack
