What is the 'Package options:' field for?

Hello all,

In DS 6.9, there is a Distribute Software task, which has the following two fields: 

'Package options:'& 'Additional command-line switches:'

The documentation explains what the latter field is for, but I have not been able to find any information concerning the 'Package options:' field. 

Does anyone know what the difference is between these two fields? 

Would 'Package options:' be used for say MSI paramters, and 'Additional command-line switches:' used for say the applications config switches like a licensing server, etc?
