RubyGems is the Ruby standard for publishing and managing third party libraries.
For user documentation, see:
For gem developer documentation see:
Further RubyGems documentation can be found at:
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 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/#{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.
You can submit bugs to the RubyGems bug tracker on RubyForge
RubyGems is currently maintained by Eric Hodel.

Activates an installed gem matching dep. The gem must satisfy requirements.
Returns true if the gem is activated, false if it is already loaded, or an exception otherwise.
Gem#activate adds the library paths in dep to $LOAD_PATH. Before a Gem is activated its required Gems are activated. If the version information is omitted, the highest version Gem of the supplied name is loaded. If a Gem is not found that meets the version requirements or a required Gem is not found, a Gem::LoadError is raised.
More information on version requirements can be found in the Gem::Requirement and Gem::Version documentation.

Find the full path to the executable for gem name. If the exec_name is not given, the gem‘s default_executable is chosen, otherwise the specified executable‘s path is returned. requirements allows you to specify specific gem versions.

Returns a list of paths matching glob that can be used by a gem to pick up features from other gems. For example:
Gem.find_files('rdoc/discover').each do |path| load path end

Adds a post-build hook that will be passed an Gem::Installer instance when Gem::Installer#install is called.
