Automating lighting builds in Unreal Engine 4.18

BuildLighting.ps1

$ContentPath = "$PSScriptRoot\Content\Levels".Replace("\", "/")
$process = Start-Process `
    -FilePath "C:\Program Files\Epic Games\UE_4.18\Engine\Binaries\Win64\UE4Editor-Cmd.exe" `
    -ArgumentList @(
        "$PSScriptRoot\MinuteOfMayhem.uproject",
        "-run=resavepackages",
        "-buildtexturestreaming",
        "-buildlighting",
        "-MapsOnly",
        "-ProjectOnly",
        "-AllowCommandletRendering",
        "-SkipSkinVerify",
        "-PACKAGEFOLDER=$ContentPath",
        "-stdout",
        "-crashforuat",
        "-unattended"
    ) `
    -NoNewWindow `
    -WorkingDirectory "$PSScriptRoot\Content" `
    -PassThru `
    -Wait
if ($process.ExitCode -ne 0) {
    Write-Output $process.ExitCode
    Write-Error -Message "Lighting build failed!"
    exit 1
}

Got any info on what the undocumented arguments like -stdout -crashforuat and -SkipSkinVerify do?
