If you want to regulate this output at all, Powershell has a standard way of controlling the output stream with `Write-Debug`, `Write-Verbose` and `Write-Warning`.  When calling the script you just pass the appropriate switch along like `-Debug`, `-Verbose`, '-Warning`.  Just be aware that there can be [some issues with redirecting those streams elsewhere](http://connect.microsoft.com/feedback/ViewFeedback.aspx?FeedbackID=297055&SiteID=99) depending on PS version.
