Thanks to the PowerShell team’s release of the Cmdlet Help Tool (http://blogs.msdn.com/powershell/archive/2007/05/08/cmdlet-help-editor-tool.aspx), I’ve updated the SAPIEN Extensions for PowerShell download (http://www.primalscript.com/freetools) to include an XML help file. Make sure the XML file is co-located with the snap-in’s DLL, and PowerShell should be able to display help for the snap-ins cmdlets, now. If you already have installed the DLL, just copy the current DLL on top of the old one (with PowerShell closed).
Still open to feedback and suggestions for additonal cmdlets to add to the package!
