Module wmiutils

This module provides a set of tools to access Common Information Model (CIM) classes through Windows Management Instrumentation (WMI).

WMI API can be accessed by various protocols such as * Windows shell -- by using 'wmic' command line tool * WMI protocol -- WMI natively provides remote connection capabilities * PowerShell -- PowerShell 2.0 also provides an access to WMI and remote connection capabilities

This module provides a set of classes which are created on top of Universal Discovery clients and provide unified interface to access CIM. That said, the code which uses this module is totally detached from the underlying protocol.
