# Bundler provides a consistent environment for Ruby projects by
# tracking and installing the exact gems and versions that are needed.
#
# Since Ruby 2.6, Bundler is a part of Ruby's standard library.
#
# Bunder is used by creating _gemfiles_ listing all the project dependencies
# and (optionally) their versions and then using
#
#   require 'bundler/setup'
#
# or Bundler.setup to setup environment where only specified gems and their
# specified versions could be used.
#
# See {Bundler website}[https://bundler.io/docs.html] for extensive documentation
# on gemfiles creation and Bundler usage.
#
# As a standard library inside project, Bundler could be used for introspection
# of loaded and required modules.
