Label

Label describes the gems in your Gemfile so you don't have to look them up to see what they do.

Just run it:

$ label

Then check out your beautiful new Gemfile:

source 'http://rubygems.org'

# Flexible authentication solution for Rails with Warden
gem 'devise'

# Upload files in your Ruby applications, map them to a range of ORMs, store
# them on different backends.
gem 'carrierwave'

# RailsAdmin is a Rails engine that provides an easy-to-use interface for
# managing your data.
gem 'rails_admin'

Label will look for a Gemfile in your current working directory by default, but you can tell it to look somewhere else if you like:

$ label /path/to/Gemfile

$ gem install label
