[Zope] Product not registering?

[VanL]

Hello,

I am trying to create a new python product that builds on a  previous 
product.  I am doing the following:

install product "Foo"
Foo installs correctly.

cp -r lib/python/Products/Foo lib/python/Products/Bar

cd lib/python/Products/Bar
search and replace "Foo", "Bar"
rename Foo.py Bar.py, etc

restart Zope, no errors

Now, the drop-down box for adding objects includes object "Bar", but the 
installed prducts screen does not list Bar as an installed product, so 
adding Bar fails.

Any help?

Thanks,

VL
