Checking for powergadgets snap-in

[marco.shaw]

Just a quick code snippet to check whether the powergadgets snap-in is loaded on a system.

One won't get any ugly errors, and the Powershell script will gracefully exit.

$err=@()

# Check for powergadgets snap-in.

$return=get-pssnapin powergadgets -ea silentlycontinue -ev err

# Check err array if powergadgets snap-in not found.  If not found, exit.

if($err.count -gt 0){write-output "Powergadgets.com snap-in does not appear to be loaded.  Exiting...";break}
