world writable directories

[Shmuel Fomberg]

Hi All.

I uploaded a module to CPAN, and got a surprising email, saying that 
PAUSE failed to index my module, because it had world writable directories.
Now, I understand the concern. My question is, considering that I work 
on a Windows machine, and have all the normal Windows tools + bsdtar 
that I installed for packing modules, how do I pack the module so it's 
directories won't be world writable?
Maybe I should mark all the directory as read-only before packing?
Thanks.
Shmuel.
