iwsyncdb.ipl -mb option

System

Maybe I'm just a little tired now but ...
I can't seem to get iwsyncdb.ipl to run with the -mb option.
It just takes the -mb option as a DCRType argument.

For example I try -

iwperl iwsyncdb.ipl -initial /default/main/Empower2.0/WORKAREA/Home -mb

or

iwperl iwsyncdb.ipl -initial -mb /default/main/Empower2.0/WORKAREA/Home

or

iwperl iwsyncdb.ipl -initial "/default/main/Empower2.0/WORKAREA/Home" -mb

or even

iwperl iwsyncdb.ipl -initial "/default/main/Empower2.0/WORKAREA/Home" synopsis/synopsis -mb
