RubyGems is a package management framework for Ruby.
This gem is an update for the RubyGems software. You must have an

$ gem update --system # you might need to be an administrator or root
See UPGRADING.rdoc for more details and alternative instructions.

If you don't have RubyGems installed, you can still do it manually:
* Download from: https://rubygems.org/pages/download
* Unpack into a directory and cd there
* Install with: ruby setup.rb # you may need admin/root privilege
For more details and other options, see:
ruby setup.rb --help
### Changes:
RubyGems 2.0 includes several new features and many breaking changes. Some of
these changes will cause existing software to break. These changes are a
result of improvements to the internals of RubyGems that make it more
maintainable and improve APIs for RubyGems users.
If you are using bundler be sure to install a 1.3.0.prerelease version or
newer. Older versions of bundler will not work with RubyGems 2.0.
Changes since RubyGems 1.8.25 (including past pre-releases):
* Breaking changes:
* Deprecated Gem.unresolved_deps in favor of
Gem::Specification.unresolved_deps
* Merged Gem::Builder into Gem::Package. Use Gem::Package.build(spec)
instead of Gem::Builder.new(spec).build
* Merged Gem::Format into Gem::Package. Use Gem::Package.new instead
of Gem::Format.from_file_by_path
* Moved Gem::OldFormat to Gem::Old. Gem::Package will
automatically detect old gems for you, so there is no need to refer to it.
* Removed Gem::DocManager, replaced by Gem::RDoc and done_installing hook
* Removed Gem::TarInput in favor of Gem::Package
* Removed Gem::TarOutput in favor of Gem::Package
* Removed Gem::RemoteFetcher#open_uri_or_path. (steveklabnik)
* Removed Gem::SSL in favor of using OpenSSL directly
* Removed Gem.loaded_path
* Removed RSS generation from the gem indexer
* Removed benchmark option from .gemrc
* Removed broken YAML gemspec support in `gem build`
* Removed support for Ruby 1.9.1
* Removed many deprecated methods
* Major enhancements:
* Improved support for default gems shipping with ruby 2.0.0+
* A gem can have arbitrary metadata through Gem::Specification#metadata
* `gem search` now defaults to --remote and is anchored like gem list. Fixes
#166
* Added --document to replace --rdoc and --ri. Use --no-document to disable
documentation, --document=rdoc to only generate rdoc.
* Only ri-format documentation is generated by default.
* `gem server` uses RDoc::Servlet from RDoc 4.0 to generate HTML
documentation.
* Add ability to install gems directly from a compatible gemdep
file (Gemfile, Isolate, gem.deps.rb)
<code>gem install --file path</code>
* Add ability to load gem activation information from a gemdeps
file (Gemfile, Isolate, gem.deps.rb).
Set RUBYGEMS_GEMDEPS=path to have it loaded. Use - as the path
to autodetect (current and parent directories are searched).
* Minor enhancements:
* Added `gem check --doctor` to clean up after failed uninstallation. Bug
#419 by Erik Hollensbe
* RubyGems no longer defaults to uninstalling gems if a dependency would be
broken. Now you must manually say "yes". Pull Request #406 by Shannon

Pull Request #412 by Sam Rawlins.
