packagemaker and soft links

Can packagemaker put soft links into a pkg? 

Take for example Office 2011 which has various soft links in amongst its folder structure in /Applications. 
How can I package that?

It is odd also because, when inspecting the contents of some pkg archives, I see their creators have somehow put soft links into the archive, but when I've tried running packagemaker on a folder containing soft links, it seems to harden the links into real file copies, or follow the links and end up in loops and crash.

I've resorted to using a postinstall script to create the soft links, but presumably there's a proper way?
