 Hi,

 that comment inspired the following observation:

 In zope.conf we can specify an out-of-Zope-tree directory
 for Products.

 # Directive: products
 #    products /home/chrism/projects/myproducts

 I believe the 'Extensions' direcrectory deserves the same rights,
 or is there a good reason (that eludes me) for not having such a feature ?

 best regards,
