In order to lay the groundwork for migrating the CMF to the new

"Zope Component Architecture",

we began fleshing out the interface declarations in the CMF.
Unfortunately, this work had the effect of colliding with a bug
in the HelpSystem's handling of a Python package, when registered
as a help directory:  the registration machinery chokes trying to
load APIs from the __init__.py!

I've patched CMFCore/__init__.py to work around this problem, and

have fixed the help system on both the 2.3 and 2.4 branches and the
head.  Here is the CMF patch:

Or you could 'cvs up' to get it.
