The vSphere PowerCLI, allows you to use PowerShell to communicate with the vSphere advanced programming interface (API).

PowerCLI 4.0 = VI Toolkit 1.5 + Bug Fixes + Host Profile Cmdlets

"Host Profile Cmdlets" Are commands that allow to create configuration files of ESX hosts and to apply to another host in order to evaluate differences.
