RubyGems 2.0.15 installed
Parsing documentation for rubygems-2.0.15
Installing ri documentation for rubygems-2.0.15



------------------------------------------------------------------------------

RubyGems installed the following executables:
        C:/Ruby200-x64/bin/gem

Ruby Interactive (ri) documentation was installed. ri is kind of like man
pages for ruby libraries. You may access it like this:
  ri Classname
  ri Classname.class_method
  ri Classname#instance_method
If you do not wish to install this documentation in the future, use the
--no-document flag, or set it as the default in your ~/.gemrc file. See
'gem help env' for details.
