# Usage examples
#   .\whatif.ps1 "Hello, World!"
#   .\whatif.ps1 "Hello, World!" -WhatIf
#   .\whatif.ps1 "Hello, World!" -Confirm
#   .\whatif.ps1 "Hello, World!" -Confirm:$False

# This is an example on how to use SupportsShouldProcess to implement
# the -WhatIf and -Confirm flags for your script

# Try setting the ConfirmImpact to "High" to enforce a confirmation from the
# user. This confirmation can be supressed by using the -Confirm:$False flag
