Compare File Permission with powershell instead of calcs , xcacls, Icacls

The following Powershershell is handy, it will compare 2 directories ACLs and report any differences.

#CompareNetworkACL.ps1
[System.IO.FileInfo] $outputFile = "C:\temp\AclCompareDump.txt"
[System.IO.DirectoryInfo] $searchDirSource = Read-Host -Prompt "Enter source project folder path to search"
[System.IO.DirectoryInfo] $searchDirTarget = Read-Host -Prompt "Enter target project folder path to search"

if ($outputFile.Exists)
{
    $outputFile.Delete()
}

if ($searchDirSource.Exists -and $searchDirTarget.Exists)
{
   foreach ( $sourceProject in $( Get-ChildItem $searchDirSource | where { $_.psIsContainer -eq $true } ) ) {
        $targetProject = Get-Item $($searchDirTarget.FullName + "\" + $sourceProject.Name)

        foreach ( $sourceArea in $( Get-ChildItem $sourceProject.FullName | where { $_.psIsContainer -eq $true } ) ) {
            $targetArea = Get-Item $($targetProject.FullName + "\" + $sourceArea.Name)

                $currentAcl = Get-Acl $sourceTaskFolder.FullName
                $refacl = Get-Acl $targetTaskFolder.Fullname

                Write-Progress -Activity "Searching source for folder ACLs..." -Status ("Comparing " + $sourceTaskFolder.FullName + " to " + $targetTaskFolder.FullName)

                $comparison = compare-object $refacl $currentAcl -Property Access
                if ($comparison -ne $null)
                {
