The ScsmPx module facilitates automation with Microsoft System Center Service

Manager by auto-loading the native modules that are included as part of that

product and enabling automatic discovery of the commands that are contained

within the native modules. It also includes dozens of complementary commands

that are not available out of the box to allow you to do much more with your

PowerShell automation efforts using the platform.
