question: How can I put empty directories into a zip-archive?

[T. Kaufmann]

Hi there,

in my directory are some 'normal' files like *.py sources and some empty 
directories too. How can I put all togehter into a zip-archive?

There is no problem to zip the *.py files but if I try to add empty directories 
  an exception is trown.

Thanks.
