Hi Nandini, this is great feedback. It's likely that not many people
are using ZK and those cmd scripts on windows. As a result things get
stale. I'd encourage you to provide some patches agains the trunk
which incorporate your fixes. You can see more detail on how to do
that here:

Regards,

Patrick
