PowerShell Scripting Global Config

My approach to scripting is to make things a reusable as possible. Hence, I always start things off from with the following global config file and script template.

CONFIG.ps1

$hosts = @("vcenter.local")
$VBRServer = "veeam.local"
$OUTPUTDIR = "c:\Shares\LOGS"
#$CREDS = Get-Credential
#####$CREDS | Export-Clixml c:\Shares\Scripts\admin.creds
$CREDS = Import-Clixml -Path c:\Shares\Scripts\admin.creds
$SMTPServer = "mail.local"
$SMTPPort = 25
$SMTPFrom = "tasker@mail.local"
$SMTPTo = "root@mail.local"
$VMExcludelist = @("vm1.local", "vm2.local", "VMware vCenter Server")

$CLUSTERExcludeList = @()
$Post = $True

)


### Script Config Vars





##
$ScriptDirectory = Split-Path -Path $MyInvocation.MyCommand.Definition -Parent
try {
	. ("$ScriptDirectory\Config.ps1")
}
catch {
	Write-Host "Error while loading supporting PowerShell Scripts" 
	exit 1
}



## Module Load
if (!(Get-Module -Name VMware.VimAutomation.Core) -and (Get-Module -ListAvailable -Name VMware.VimAutomation.Core)) {  
	Write-Output "loading the VMware COre Module..."  
	if (!(Import-Module -Name VMware.VimAutomation.Core -ErrorAction SilentlyContinue)) {  
		# Error out if loading fails  
		Write-Error "`nERROR: Cannot load the VMware Module. Is the PowerCLI installed?"  
	}  
	$Loaded = $True  
}  
elseif (!(Get-PSSnapin -Name VMware.VimAutomation.Core -ErrorAction SilentlyContinue) -and !(Get-Module -Name VMware.VimAutomation.Core) -and ($Loaded -ne $True)) {  
	Write-Output "loading the VMware Core Snapin..."  
	if (!(Add-PSSnapin -PassThru VMware.VimAutomation.Core -ErrorAction SilentlyContinue)) {  
		# Error out if loading fails  
		Write-Error "`nERROR: Cannot load the VMware Snapin or Module. Is the PowerCLI installed?"  
		Write-Host "Try: 'Install-Module VMware.PowerCLI'"
	}  
}
