# 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 <tt>gem:</tt> 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
#
# 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)
