Gem::ConfigFile RubyGems options and gem command options from gemrc.
gemrc is a YAML file that uses strings to match gem command arguments and symbols to match RubyGems options.
Gem command arguments use a String key that matches the command name and allow you to specify default arguments:
install: --no-rdoc --no-ri update: --no-rdoc --no-ri
You can use gem: to set default arguments for all commands.
RubyGems options use symbol keys. Valid options are:
:backtrace
See backtrace
:sources
Sets Gem::sources
:verbose
See verbose
:concurrent_downloads
gemrc files may exist in various locations and are read and merged in the following order:
system wide (/etc/gemrc)
per user (~/.gemrc)
per environment (gemrc files listed in the GEMRC environment variable)

An Uninstaller.
The uninstaller fires pre and post uninstall hooks. Hooks can be added either through a rubygems_plugin.rb file in an installed gem or via a rubygems/defaults/#{RUBY_ENGINE}.rb or rubygems/defaults/operating_system.rb file. See Gem.pre_uninstall and Gem.post_uninstall for details.
