From what I can tell the feature that is "Hotfix"ed does not appear until Zope 2.7.3. If the Hotfix is installed in Zope 2.7.0 through to 2.7.2 then it shows up as a broken product. No real harm done.
The product import breaks with: Traceback (most recent call last): File "/usr/local/www/Zope/lib/python/OFS/Application.py", line 660, in import_product product=__import__(pname, global_dict, global_dict, silly) File "/usr/local/www/Zope/Atrac/Products/Hotfix_20060821/__init__.py", line 8, in ? from docutils.parsers.rst.directives import tables ImportError: cannot import name tables And we see that ``tables`` not show up till Zope 2.7.3 via: http://cvs.zope.org/Zope/lib/python/docutils/parsers/rst/directives/Attic/ta... And a casual glance around docutils before ``tables`` was introducded suggests that feature was not part of another module. Cheers Michael
