Compatibly renamed Gem::DependencyResolver to Gem::Resolver. Added support for git gems in gem.deps.rb and Gemfile. Fixed resolver bugs. * test/rubygems: ditto. * lib/rubygems/LICENSE.txt: Updated to license from RubyGems trunk. [ruby-trunk - Bug #9086] * lib/rubygems/commands/which_command.rb: RubyGems now indicates failure when any file is missing. [ruby-trunk - Bug #9004] * lib/rubygems/ext/builder: Extensions are now installed into the extension install directory and the first directory in the require path from the gem. This allows backwards compatibility with msgpack and other gems that calculate full require paths. [ruby-trunk - Bug #9106] git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@43714 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

# A VendorSet represents gems that have been unpacked into a specific

#
|
|
# set = Gem::Resolver::VendorSet.new

#
|

# set.add_vendor_gem 'rake', 'vendor/rake'
|

|
|
# The directory vendor/rake must contain an unpacked rake gem along with a
|
|
# rake.gemspec (watching the given name).
