Hi, you might know that the "famous" Zope Book is available as Debian package to increase the comfort of the Debian users and to make this fine work pupular in the Debian world. You might have heard that there is some trouble with license of documentation in Debian and this trouble now has hit the Open Publication License and thus the Zope Book package. This is explained at http://bugs.debian.org/266417 The problem is explained in Detail at http://people.debian.org/~srivasta/Position_Statement.html to make clear why Debian can not distribute documentation with licenses which are not compliant to the Debian Free Software Guidelines. I have to admit that I personally do not really understand these issues and just do foreward this information to you. A short resume of it might be: Just put the documentation under the same license as the software. The same is true for the Zope Development Guide: http://bugs.debian.org/266414 So if you - especially the authors of the documentation - have certain reasons to stick to the license you have choosen, I would have to move these two packages to the non-free section of the Debian mirrors. Kind regards and thanks for your attention Andreas.
