 ==argument string variantname optional multiple
 
 A symbolic name for the hardware variant may be specified instead of having to know the machine uid. This maximises compatibility with platforms that provide a custom variant.exe and/or that need more than just the machine UID to determine the variant. Check the platform-specific documentation for what variant string is used to identify that platform's hardware. If multiple variant names are specified KErrNone is returned if any one of them matches.
