# Runs the install procedures for a specific Gemfile.
    #
    # Firstly, this method will check to see if `Bundler.bundle_path` exists
    # and if not then Bundler will create the directory. This is usually the same
    # location as RubyGems which typically is the `~/.gem` directory
    # unless other specified.
    #
    # Secondly, it checks if Bundler has been configured to be "frozen".
    # Frozen ensures that the Gemfile and the Gemfile.lock file are matching.
    # This stops a situation where a developer may update the Gemfile but may not run
    # `bundle install`, which leads to the Gemfile.lock file not being correctly updated.
    # If this file is not correctly updated then any other developer running
    # `bundle install` will potentially not install the correct gems.
    #
    # Thirdly, Bundler checks if there are any dependencies specified in the Gemfile.
    # If there are no dependencies specified then Bundler returns a warning message stating
    # so and this method returns.
    #
    # Fourthly, Bundler checks if the Gemfile.lock exists, and if so
    # then proceeds to set up a definition based on the Gemfile and the Gemfile.lock.
    # During this step Bundler will also download information about any new gems
    # that are not in the Gemfile.lock and resolve any dependencies if needed.
    #
    # Fifthly, Bundler resolves the dependencies either through a cache of gems or by remote.
    # This then leads into the gems being installed, along with stubs for their executables,
    # but only if the --binstubs option has been passed or Bundler.options[:bin] has been set
    # earlier.
    #
    # Sixthly, a new Gemfile.lock is created from the installed gems to ensure that the next time
    # that a user runs `bundle install` they will receive any updates from this process.
    #
    # Finally, if the user has specified the standalone flag, Bundler will generate the needed
    # require paths and save them in a `setup.rb` file. See `bundle standalone --help` for more
    # information.
