###Compiles the example
RegionalNamespaces -ConfigurationData $PSScriptRoot\RegionalNamespaces-Config.psd1 -ShellCreds $ShellCreds

###Sets up LCM on target computers to decrypt credentials.
#Set-DscLocalConfigurationManager -Path .\RegionalNamespaces -Verbose

###Pushes configuration and waits for execution
#Start-DscConfiguration -Path .\RegionalNamespaces -Verbose -Wait
