ruby-wmi is an ActiveRecord style interface for Microsoft's Windows Management Instrumentation provider. Many of the methods in WMI::Base are borrowed directly, or with some modification from ActiveRecord. http://api.rubyonrails.org/classes/ActiveRecord/Base.html The major tool in this library is the #find method. For more information, see WMI::Base. There is also a WMI.sublasses method included for reflection.
