Dear Andreas and Jonathan, first a mistake: I want to access
'Extensions' folder as you mentioned Jonathan, not 'import'.

Andreas, I've done that, I can see several path there like
.../instance/Products/Sprout/src, .../lib/python/Zope2/Startup etc.,
but none for .../instance/Extensions.

I was hoping that I could get the path where 'Extensions' is because I
work with several zope installations in several platforms and I would
like to make my module independent of a variable inside its code that
should be manually adjusted for every situation.

And yes, I am aware about adding the path only once (that's why
there's a 'if') and then I avoid recursive insertions.

You can easily check what's in your sys.path by having your external method
return it.

Typically, the Extensions directory (where your external methods live) are
not in the default path and need to be added to sys.path.(warning: be
careful on how you do this or everytime your external method gets called it
will add to the sys.path and will eventually cause you grief!).
