Why do I have not access to all SUWpdate options?

Hi

I use the SWUpdate tool within the system without the DIGI update-firmware tool.
I included the SWUpdate tool additionally in one of my recipes.
with
swupdate
swupdate-www

No the problem:
I don’t have access to the following SWUpdate options.
-r
-w
-u
-t
-a
Why is this so?

Regards
Michael
