+The environment command lets you query rubygems for its configuration for
+use in shell scripts or as a debugging aid.
+
+The RubyGems environment can be controlled through command line arguments,
+gemrc files, environment variables and built-in defaults.
+
+Command line argument defaults and some RubyGems defaults can be set in a
+~/.gemrc file for individual users and a gemrc in the SYSTEM CONFIGURATION
+DIRECTORY for all users. These files are YAML files with the following YAML
+keys:
+
+ :sources: A YAML array of remote gem repositories to install gems from
+ :verbose: Verbosity of the gem command. false, true, and :really are the
+ levels
+ :update_sources: Enable/disable automatic updating of repository metadata
+ :backtrace: Print backtrace when RubyGems encounters an error
+ :gempath: The paths in which to look for gems
+ :disable_default_gem_server: Force specification of gem server host on push
+ <gem_command>: A string containing arguments for the specified gem command
+
+Example:
+
+ :verbose: false
+ install: --no-wrappers
+ update: --no-wrappers
+ :disable_default_gem_server: true
+
+RubyGems' default local repository can be overridden with the GEM_PATH and
+GEM_HOME environment variables. GEM_HOME sets the default repository to
+install into. GEM_PATH allows multiple local repositories to be searched for
+gems.
+
+If you are behind a proxy server, RubyGems uses the HTTP_PROXY,
+HTTP_PROXY_USER and HTTP_PROXY_PASS environment variables to discover the
+proxy server.
+
+If you would like to push gems to a private gem server the RUBYGEMS_HOST
+environment variable can be set to the URI for that server.
+
+If you are packaging RubyGems all of RubyGems' defaults are in
+lib/rubygems/defaults.rb. You may override these in
+lib/rubygems/defaults/operating_system.rb
