Dear All,

I will perform the changes proposed in "FS#386 - Replace link 'dune'"
within the next days.

As these changes will change the repository structure, everybody is
adviced to commit his changes before.

We have to agree on a certain date for the change. I ask everybody to
commit his changes till
  Tuesday 13th october 2009 18:00
I will then announce once all changes are performed.

Christian
