# Allows for declaring a Gemfile inline in a ruby script, optionally installing
# any gems that aren't already installed on the user's system.
#
# @note Every gem that is specified in this 'Gemfile' will be `require`d, as if
#       the user had manually called `Bundler.require`. To avoid a requested gem
#       being automatically required, add the `:require => false` option to the
#       `gem` dependency declaration.
#
# @param install [Boolean] whether gems that aren't already installed on the
#                          user's system should be installed.
#                          Defaults to `false`.
#
# @param gemfile [Proc]    a block that is evaluated as a `Gemfile`.
#
# @example Using an inline Gemfile
#
#          #!/usr/bin/env ruby
#
#          require 'bundler/inline'
#
#          gemfile do
#            source 'https://rubygems.org'
#            gem 'json', require: false
#            gem 'nap', require: 'rest'
#            gem 'cocoapods', '~> 0.34.1'
#          end

#          puts Pod::VERSION # => "0.34.4"
