[Zope] Mutliple "Extension" directories?

[David Hassalevris]

.
I've developed a fair number of external python scripts - all of which are
located in the Zope\Extensions directory (thats the protocal).

Of course when the number of scripts becomes large the directory becomes
crowded.

I would like to include the ability to add *addional* directories that would
be searched when an external script is called.
For examaple, the start script could have a new paramater
EXTERNAL=Extensions;extern1;extern2;etc

Does this sound like something that is implementable?  Does it even sound
like a good idea?

Thanks for any thoughts,

David
