# Bundler provides a consistent environment for Ruby projects by
|
|
# tracking and installing the exact gems and versions that are needed.
|
|
#
|
|
# Bundler is a part of Ruby's standard library.
|
|
#
|
|
# Bundler 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.
