# 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`
# :   See #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)
#
