#
# == RubyGems Plugins
#
# As of RubyGems 1.3.2, RubyGems will load plugins installed in gems 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 discovered via
# Gem::find_files then loaded. Take care when implementing a plugin as your
# plugin file may be loaded multiple times if multiple versions of your gem
# are installed.
#
# For an example plugin, see the graph gem which adds a `gem graph` command.
#
# == RubyGems Defaults, Packaging
#
# RubyGems defaults are stored in rubygems/defaults.rb. If you're packaging
# RubyGems or implementing Ruby you can change RubyGems' defaults.
#
# For RubyGems packagers, provide lib/rubygems/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 and 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
