# 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.
