# RubyGems is the Ruby standard for publishing and managing third party
# libraries.
#
# For user documentation, see:
#
# * <tt>gem help</tt> and <tt>gem help [command]</tt>
# * {RubyGems User Guide}[https://guides.rubygems.org/]
# * {Frequently Asked Questions}[https://guides.rubygems.org/faqs]
#
# For gem developer documentation see:
#
# * {Creating Gems}[https://guides.rubygems.org/make-your-own-gem]
# * Gem::Specification
# * Gem::Version for version dependency notes
#
# Further RubyGems documentation can be found at:

# * {RubyGems API}[https://www.rubydoc.info/github/rubygems/rubygems] (also available from
# <tt>gem server</tt>)
#
# == RubyGems Plugins
#
# RubyGems will load plugins in the latest version of each installed gem or
# $LOAD_PATH. Plugins must be named 'rubygems_plugin' (.rb, .so, etc) and
# placed at the root of your gem's #require_path. Plugins are installed at a
# special location and loaded on boot.
#
# For an example plugin, see the {Graph gem}[https://github.com/seattlerb/graph]
# which adds a <tt>gem graph</tt> command.
#
# == RubyGems Defaults, Packaging
#
# RubyGems defaults are stored in lib/rubygems/defaults.rb. If you're packaging
# RubyGems or implementing Ruby you can change RubyGems' defaults.
#
# For RubyGems packagers, provide lib/rubygems/defaults/operating_system.rb
# and override any defaults from lib/rubygems/defaults.rb.
#
# For Ruby implementers, provide lib/rubygems/defaults/#{RUBY_ENGINE}.rb and
# override any defaults from lib/rubygems/defaults.rb.
#
# If you need RubyGems to perform extra work on install or uninstall, your
# defaults override file can set pre/post install and uninstall hooks.
# See Gem::pre_install, Gem::pre_uninstall, Gem::post_install,
# Gem::post_uninstall.
#
# == Bugs
#
# You can submit bugs to the
# {RubyGems bug tracker}[https://github.com/rubygems/rubygems/issues]
# on GitHub
