Moved help system code to the HelpSys module. Removed the HelpSystem module. This was done to improve backword compatibility with Zope 2.1.6 and earlier.

Zope's built recently from CVS may have problems with this change. If I hear a lot of complaints I may add backward compatibility, otherwise it should be easy enough fix by either erasing your database or replacing your HelpSys object.

Added support for getPhysicalRoot method, which is actually acquired
from the top-level object. We actually set the attribute to

that makes it callable only from Python.

Added unrestrictedTraverse, which does publisher-style traversal
(__bobo_traverse__, getattr, getitem) without security checks.
Provide a setting that makes it private.

Added getPhysicalRoot method, which just returns self. This methof is acquired by objects that need to get hold of the top-level application object.
