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
