+// Last element of Key becomes prop, first part is the path and optionally nodes,

 // Values can be the following: Value (string) and Final (dword, optional)

 // For example the following registry setting:
 // [HKEY_LOCAL_MACHINE\SOFTWARE\Policies\LibreOffice\org.openoffice.UserProfile\Data\o]
 // "Value"="Example Corp."
 // "Final"=dword:00000001
 // becomes the following in configuration:
